Microsoft 365 (and Office 365) subscribers get more frequent software updates than those who have purchased Office without a subscription, which means subscribers have access to the latest features, security patches, and bug fixes. But it can be hard to keep track of the changes in each update and know when they’re available. We’re doing this for you, so you don’t have to.

Following are summaries of the updates to Microsoft 365/Office 365 for Windows over the past year, with the latest releases shown first. We’ll add info about new updates as they’re rolled out.

Note: This story covers updates released to the Current Channel for Microsoft 365/Office 365 subscriptions. If you’re a member of Microsoft’s Office Insider preview program or want to get a sneak peek at upcoming features, see the Microsoft 365 Insider blog.

While AI is proliferating across the workplace, it is introducing a new productivity paradox: While the technology makes work feel faster, it actually pushes more burden onto employees to provide context, perform quality checks, then rinse and repeat across numerous disparate tools.

This, according to a new survey of 6,000 full-time digital workers by Glean’s Work AI Institute, results in two emerging behaviors: “botsitting,” all the unrecognized work that goes into making AI actually usable; and “botshitting,” shipping AI-generated work that is unverified, not that well understood, or perhaps not even trustworthy. The survey report was co-authored by experts from Work AI Institute, Emory University, Stanford University, UC Berkeley, UC Santa Barbara, UNC Charlotte, University College London, and University of Notre Dame.

“It’s definitely in many ways a vicious cycle that feeds itself,” said Rebecca Hinds, head of Glean’s research center the Work AI Institute, a research collaborative of AI experts. Enterprises need to begin understanding and addressing the “massive, massive human labor that’s at the core of this.”

Workers are using AI more, getting more frustrated

There’s no doubt that AI is quickly becoming a central teammate in the workplace. Glean’s Work AI Institute found that 87% of digital workers are using AI: It is already automating more than a quarter of their work and saving about 11 hours a week.

Still, only 13% say the use of AI has significantly improved their company’s performance, and their time savings are being eaten up by the same technology that is producing them. Employees lose about one-third of their work week (6.4 hours) botsitting: feeding AI context, supervising outputs, debugging errors, cleaning up AI-generated work, and switching between AI tools.

“We’re seeing high, high rates of multiple tool usage, and often those tools aren’t connected,” said Hinds.

In terms of context-feeding, large language models (LLMs) are trained on the vast corpus of the internet, but not always on enterprise-specific data. Thus, employees often have to provide additional information around their company’s products, customers, services, or other details.

“They’re often feeling frustrated when the tools don’t understand enough about day to day work to be useful,” said Hinds. Also, because employees are using multiple tools, they often have to repeat the same prompt over and over.

“It’s exhausting for workers to not only do this, but to have the work be unrecognized, often unrewarded and unacknowledged within the organization,” she said.

Similarly, workers are having to catch outputs that might look polished and finished on the surface, but could be wrong, incomplete, or missing important context. Debugging is the biggest driver of exhaustion, because it is often conducted by people who didn’t necessarily contribute to the initial output, Hinds noted, so they first have to dig up background information.

However, “not all botsitting is bad,” Hinds emphasized. “Certainly, we want workers to have some level of ownership and oversight.”

But when it is unnecessary, it can lead to botshitting, where users ship AI-generated work they haven’t verified because they’re overwhelmed or time-constrained. Sixty-nine percent of users admit to doing so, and 41% say they sometimes deliver work they could not explain if asked. Another 28% blame AI for mistakes they themselves caused.

“Botshitting is offloading your critical human thinking, judgment, and understanding,” Hinds explained. “You’re offloading that work that absolutely needs to remain with the human.”

Workers using multiple AI agents are significantly more likely to do this, she added, because agents are so scalable, and can spiral out of control if they don’t have the right controls or permissions built around them, causing overwhelmed users to give up on their verification efforts.

“You don’t often see the negative impacts until 3, 4, 5, steps down the line,” said Hinds. “Then it requires all of this cleanup work, detective work, to understand where did the agent go wrong.”

Using AI … but not too much

Interestingly, more than half of the workers surveyed said they get more day-to-day help from AI than they get from their managers, and consider it easier to collaborate with than humans.

Still, they seem to be facing a Goldilocks problem when it comes to sharing their use of AI. Among self-identified high AI achievers, 54% are using unapproved tools or using approved tools in noncompliant ways, and 36% are hiding how much AI helps them.

As Hinds explained, depending on the context and the level of psychological safety an organization has provided, it can be “differentially beneficial or harmful” to show you’re using AI, and, on the flip side, to conceal that you’re using it too much, because that might make you less valuable, or perceived as less valuable, she said.

It’s a complicated balance, because, she noted, “there’s massive pressure in so many organizations to demonstrate AI fluency, to demonstrate you’re a power user.”

What successful organizations are doing differently

In fact, the report said, “The companies pulling ahead are doing something different. They aren’t spending a greater share of their AI time using AI. They’re spending a greater share on the work around it: setting context, defining what ‘good’ looks like, building judgment, and deciding what should never have been handed to a model in the first place.”

The most transformative organizations are addressing AI challenges proactively: Providing training and support, treating AI as an opportunity to redesign work, and formally rewarding AI skills. In addition, it noted, the hardest skill to build is knowing when not to use AI.

It is “not just clicks of the tool, not just tokens used, but real skills, real learning,” said Hinds. In addition to investing in workers, these organizations are clearly stating AI strategy and clarifying the “why” behind it. Governance should also be “living and breathing,” with companies continuously re-evaluating policies.

And it needs to happen at every level, top execs included, said Hinds: “It’s being able to see the executives use the technology, sharing both the success stories and the failures.”

Successful companies are also actively using metrics anchored in existing key performance indicators (KPIs). They are measuring quality, efficiency, and employee engagement in different ways, and putting data in the hands of employees so they can assess their own adoption and success.

“It’s less about surveillance and more about feedback in terms of how we work collectively,” said Hinds.

What’s “fascinating but perhaps not surprising,” she said, is that workers are increasingly using AI itself as a teacher, and prefer it over other learning channels. This speaks to the importance of low-code, no-code tools, with low learning curves and organizational context, that are embedded directly into workflows.

“It is starkly different from what we’ve seen with previous technologies,” she said.

Multiple reports indicate that Chinese operatives continue using every tech tool at their disposal – including American AI – to amass data on and manipulate everyone from security-clearance holders to everyday US citizens. And they’re trying to influence public opinion on building datacenters for AI, albeit without success so far. One of these reports found a “significant resurgence” of a botnet linked to Chinese government-backed goons, including Volt Typhoon, which previously used a covert network of connected devices to burrow deep into critical US networks and preposition for future destructive attacks. In January 2024, the FBI said it killed Volt’s KV-botnet, comprised of hundreds of end-of-life routers and other internet-connected devices. At the time, KV-botnet consisted of four clusters, with the KV cluster primarily being used as a covert data transfer network, and the JDY cluster used for scanning and reconnaissance. In a Wednesday report, Lumen’s Black Lotus Labs said that while the KV cluster became largely defunct after the law enforcement takedown, the JDY cluster remains an active threat, and has since surged to more than 1,500 compromised routers and IoT devices. “Analysis of this activity shows a clear focus on identifying vulnerable infrastructure shortly after public vulnerability disclosures, suggesting that reconnaissance output is rapidly operationalized by China-nexus advanced persistent threat (APT) actors,” the threat intel team wrote. “This targeted focus has been observed across a range of sectors, with the US military and associated entities as the most prominent.” While the botnet resurgence poses the most pressing threat, and the security shop recommends all enterprises implement CISA and NCSC guidance for mitigating Volt Typhoon activity and defending against China-nexus covert networks of compromised devices, another report indicates that China’s attempts at influence operations haven’t died down, either. Using American AI for covert ops about … American AI OpenAI in a Wednesday report said it banned ChatGPT accounts likely originating from China after they used the American AI company’s models to generate content for covert operations about – wait for it – American AI. While neither of the two clusters seemed to have much success in sowing chaos or swaying opinions, the fact that they tried at all is significant, according to Ben Nimmo, principal investigator on OpenAI’s Intelligence and Investigations team. “Neither campaign appears to have gained much authentic engagement,” Nimmo told reporters. “They're important for what they reveal about the intentions of influence operators from China and the narratives they're testing and seeking to amplify.” The first cluster used ChatGPT to generate social media content and images for an operation claiming datacenters and AI applications are increasing electricity demand and causing higher costs for ordinary Americans. “For example, they asked for comic strips about a power grid operator’s capacity auction prices based on reporting from a legitimate regional paper,” the report says. “They asked ChatGPT to focus the comments on rising capacity prices as a consequence of peak electricity demand, framing the new demand as coming from data centers and AI applications and argued that these costs were ultimately passed to ordinary households.” The operators then posted these comments and images on X, likely using fake accounts, with links to real news stories about datacenters. OpenAI suspects the operators are part of a social-media team at a private Chinese tech company that provides services for Chinese provincial-level government clients. “This was not a case of an influence operation creating a debate,” Nimmo said. “The debate existed already. This was an influence operation from China trying to interfere in it. We didn't see any signs that they succeeded.” The second cluster of banned ChatGPT accounts also likely originated in China and used OpenAI’s models to write comments and draw political cartoons criticizing US tech policies and tariffs. “Interestingly, the operators specified in their prompts that the content should not include cartoons of Xi Jinping in the output and should only include President Trump,” Nimmo said. These accounts, all writing prompts in simplified Chinese and using VPNs to access the AI systems, also used ChatGPT to edit work reports and help design social media monitoring systems. “This isn't the first time that we've seen actors in China trying to come up with ideas for social media monitoring,” Nimmo said. In February, OpenAI said it banned ChatGPT accounts believed to be linked to Chinese government entities attempting to use AI models to surveil individuals and social media accounts. If AI doesn't work, bribery might? If Chinese agents can’t use AI systems to unearth sensitive information, there are always fake websites and job offers promising cash for state secrets. We’ve seen Beijing-linked government snoops use these tactics in the past, and according to the US Justice Department, they’re still using this scam (because it works). On Wednesday, the feds said they obtained a warrant for and seized 13 fake consulting company websites used to target US persons, including current and former security clearance holders with access to classified and sensitive government information. The domains include centrikglobalconsulting.com, rightinfoconsult.com, finnaclevesperconsulting.com, cydfconsulting.com, pulsewaveglobal.com, catalystglobalsolutions.com, thehorizzen.com, geoindopacific.com, gpf-ina.org, safesec-group.com, thetruthinfo.com, Vandercons.com, and gulfpeace.org. Since November 2023, these websites and associated job postings on social media, LinkedIn, and other hiring platforms advertised “consulting” jobs, including “Senior Analyst” and “International Affairs Consultant” positions. Suspected PRC operatives used the sites and job listings to recruit applicants and bribe them for sensitive information, DOJ alleges. “The conspirators have encouraged applicants and recruits to share confidential and sensitive information in violation of their official duties and of particular interest to the People's Republic of China (PRC) government,” according to the court documents. “The recruiters pressured candidates to share confidential information and reports from ‘insider sources' in violation of their official duties.” The court documents allege the conspirators then paid the recruits for these reports using online accounts in the names of fictitious individuals, and cryptocurrency to hide their identities and the source of the payments. ®

They are angry at Redmond and will have their revenge. Nightmare Eclipse, the prolific bug hunter and possibly disgruntled ex-Microsoft employee, disclosed another zero-day vulnerability just hours after Redmond issued a record-breaking number of CVEs and fixes for June Patch Tuesday. The latest zero-day, RoguePlanet, targets Microsoft Defender and works against fully patched Windows 10 and Windows 11 systems, according to the researcher, who also released proof-of-concept exploit code for the security flaw. Assuming the attacker can win a race condition, this bug allows local privilege escalation and leads to SYSTEM-level control over an affected machine. Nightmare Eclipse (aka Chaotic Eclipse) is a disgruntled bug hunter with a deep understanding of Windows and an even deeper grudge against Microsoft. They claim to be an ex-employee, and accuse Redmond of ignoring vulnerability reports and refusing to communicate with them. "When I actively asked you to communicate with me, you refused, humiliated me and made sure to insult me in front of people," they wrote in an earlier blog post that also promised a “bone shattering” drop on July 14. "You defame me in public with your CVE-2026-45585 advisory even though you literally deleted the Microsoft account I used to report bugs to you with and I got zero pennies from doing so and I still happily did like an idiot," the post continued. Possibly as an outlet for this anger, and reportedly in response to Redmond's lack of action, Nightmare began releasing their findings to the public. RoguePlanet marks the seventh Microsoft zero-day that they found and disclosed - accompanied by either a PoC exploit or technical details - before Redmond issued a fix. Microsoft's initial response to those disclosures was widely interpreted as a threat of legal action, prompting massive outrage from the broader infosec community before Redmond sought to calm the backlash by stating it had "no intention to pursue action against individuals conducting or publishing security research." As of Tuesday, the previous six zero-days all have patches. Three of them, RedSun, UnDefend, and BlueHammer, came under attack soon after Nightmare published working exploit code for each and before Microsoft released security updates to address the flaws. The other three, YellowKey, GreenPlasma, and MiniPlasma, all have been fixed as of June’s Patch Tuesday. YellowKey (aka CVE-2026-45585) is a security feature bypass bug in Windows BitLocker. An attacker with physical access to the vulnerable system could bypass the BitLocker Device Encryption feature and gain access to the device's encrypted data. GreenPlasma (aka CVE-2026-45586) and MiniPlasma (aka CVE-2020-17103) are both privilege escalation flaws in the Collaborative Translation Framework (CTFMON) and the Cloud Files Mini Filter Driver that can be abused by an authorized attacker to elevate privileges locally and gain SYSTEM access. When asked about RoguePlanet, a Microsoft spokesperson told The Register that the Windows giant is “aware of the reported vulnerability and is actively investigating the validity and potential applicability of these claims." The spokesperson continued: "Microsoft is committed to investigating security issues and updating impacted products to protect customers as soon as possible. Importantly, we support coordinated vulnerability disclosure, an industry standard that protects customers and supports the research community by ensuring their findings are thoroughly investigated and addressed before being made public." Soon after Nightmare published a PoC for RoguePlanet, the ThreatLocker threat intelligence team validated the exploit code and said that they were “actively assessing impact, affected systems, and additional mitigations,” promising to share more findings “as they become available.” Tharros Labs senior vulnerability analyst and long-time respected security sleuth Will Dormann said he tested the exploit code, too. “It's reportedly not 100% reliable, but it worked on the first attempt for me,” Dormann wrote. Nightmare, for their part, rolled back the promise of a “bone shattering” drop on July 14. “(Un)fortunately I will be unable to mass disclose zerodays in July 14th, RoguePlanet took way more time than expected and truly drained me,” the researcher said on Tuesday. “I might take a break but I can't say for sure what I will be doing for next month, maybe it's nothing, maybe it's smtg. But the big thing is not happening. I did not intend to spread a mass panic with that post and I apologize for doing so.”®

New drugs are taking on the slippery molecular switches that fuel deadly cancers—and AI is speeding up the hunt.

For decades, a handful of molecular switches has haunted the nightmares of cancer researchers. The switches trigger runaway tumor growth and cause the disease to spread across the body in multiple cancers. In theory, this makes them perfect treatment targets. Blocking even one could lead to drugs that are effective against a variety of cancers.

But despite considerable efforts, these switches—all of which are proteins—have escaped our most advanced cancer treatments, earning them the term “undruggable.” This is largely due to a shared trait: They all have smooth surfaces, making it difficult for drugs to interact with them.

But maybe not for much longer.

Researchers recently reported promising results for a new medication targeting a family of undruggable proteins in a clinical trial for advanced pancreatic cancer. The drug, daraxonrasib, nearly doubled survival time compared to chemotherapy, with fewer side effects. It’s not a total cure. But the treatment gives patients precious time, adding roughly 13 months after diagnosis. Patients also reported less pain and better quality of life.

Daraxonrasib is the latest in a new generation of drugs aimed at undruggable proteins. And AI-based tools are now poised to further accelerate progress in the field.

RAS Attack

The RAS family was the first group of oncogenes—or genes that drive cancer—ever discovered. The genes became a major focus in 1982 when several teams independently showed the mutation of a single DNA letter could transform RAS genes into a potent cancer trigger.

The proteins RAS genes encode are like spring-loaded molecular switches that relay signals from a cell’s surroundings. When proteins called growth factors latch onto a cell, RAS switches flip on to promote cell growth and survival, while built-in safeguards quickly turn them off again.

Cancerous mutations break this cycle. The switches get stuck in the “on” position, continuously instructing cells to grow and divide. This is, of course, a hallmark of cancer.

An ideal drug would simply switch RAS off. But most drugs are like rock climbers. They need grooves, pockets, or bumps on a protein to grab onto. Similar to a smooth rock face, RAS offers few such features. Making matters worse, different mutations subtly reshape the protein, so it’s tough to build a one-size-fits-all inhibitor.

The first RAS drug wasn’t approved in the US until 2021, nearly four decades after discovering the genes’ role in cancer. Even then, the drug targeted just one family member of three, limiting its reach to a relatively small group of patients. Many eventually developed resistance.

That’s why daraxonrasib turned heads. Developed by Revolution Medicines in Redwood City, California, the drugs switches off all three RAS family members. Rather than trying to grip the slippery proteins directly, it binds to a partner molecule that helps RAS proteins fold into their final 3D shapes. In this way, the drug hitches a ride on active RAS and shuts the proteins down.

The workaround paid off. The new study enrolled 500 people worldwide with advanced pancreatic cancer. All participants had already tried cancer therapies with limited success. On average, patients receiving daraxonrasib lived 13.2 months and spent most of that time with limited pain. The most common discomfort was a rash. Those receiving chemotherapy fared worse, living roughly 6.6 months and experienced more severe side effects.

The results don’t rival the dramatic success of CAR T cell therapies in blood cancer. In CAR T, caregivers engineer a patient’s own immune cells to recognize and attack tumors, sometimes producing long-lasting remission after a single infusion.

But the findings have energized the field. If approved, a daily daraxonrasib pill would likely be far more affordable and easier to administer than a personalized cell therapy. And because RAS mutations fuel many solid cancers—which CAR T still struggles to control—the drug could offer a new defense against deadly cancers that are largely beyond cell therapy’s reach. Combining daraxonrasib with earlier-generation RAS inhibitors may further boost its effects.

The Genome Guardian

Daraxonrasib didn’t appear overnight. Scientists used a crystallized snapshot of its target protein as a molecular blueprint. Years of medicinal chemistry followed, with scientists repeatedly tweaking candidate compounds to boost potency, improve selectivity, and minimize toxicity.

AI could dramatically accelerate similar efforts against other undruggable cancer targets. Among the most coveted is p53, often called the “guardian of the genome” for its dizzying array of roles. The protein orchestrates the activity of over 300 genes involved in DNA repair, metabolism, cell death, and inflammation, making it one of the cell’s most important defense systems.

Since its discovery in 1979, p53 has been both a holy grail and a headache for cancer researchers. Mutations in the gene are common in multiple cancers. But like RAS, the protein is flat and smooth. Some mutations destabilize its structure; others turn it into misfolded clumps. A universal p53 drug has remained elusive.

Some researchers are trying to restore the protein. In a small trial earlier this year, they tested a drug that restabilizes a common mutant form of p53. Within 21 days, tumors shrank roughly 20 percent in patients with ovarian, breast, and several other solid cancers.

Other researchers aim to selectively kill cells carrying the mutation. Using AI, a team at Baylor College of Medicine screened nearly 10 million compounds that cause mutated p53 cells to self-destruct, while sparing healthy cells. The search uncovered 83 chemically distinct candidates. One called H3 dramatically suppressed tumor growth in mice.

“These results highlight the potential use of AI-powered drug screening to investigate individual p53 mutants in the future,” they wrote. Although the approach is early-stage and only focused on one mutation, the team is hopeful it can be extended to other cancerous mutations.

Most Wanted

MYC is another formerly undruggable protein that could now be vulnerable. Roughly 70 percent of cancers have abnormal MYC activity. Normally, the protein is a master regulator of growth, directing cells to manufacture proteins, replicate DNA, absorb nutrients, and divide when needed.

Cancer finds many ways to hijack the system and keep cells in a state of runaway growth. MYC gene mutations aren’t just single-letter swaps. Sometimes the gene duplicates or is rearranged across the genome, churning out excessive amounts of the protein it encodes. This genetic diversity makes approaches using gene therapy difficult. And again, like RAS, the MYC protein’s smooth, featureless surface lacks stable anchors for drugs.

An emerging strategy is to disrupt MYC’s interaction with other proteins that it needs to function. A designer protein blocking MYC activity, for example, recently showed promise in a small trial against solid cancers. Other teams are using AI to identify drugs that limit MYC’s ability to fix damaged DNA in tumors, kneecapping their ability to divide. Meanwhile, biotechnology companies are deploying AI to map out MYC’s structure and molecular interactions in search of new ways to shut the protein down.

Daraxonrasib’s success shows that undruggable proteins aren’t untouchable. There’s a lot more work ahead to prove other similar drugs can work too. But scientists are increasingly leaning into AI during all stages of drug development to speed up the process. Maybe, one day, “undruggable” will disappear from our vocabulary altogether.
