Imagine this: You’ve just finished a critical document or a long email, you hit “Save,” and suddenly—nothing. Your screen freezes, the cursor spins endlessly, and your application enters the dreaded state of “Not Responding.”
If this sounds like your week, you aren’t alone. A frustrating new bug in the latest Windows 11 update is causing freezes for users relying on cloud storage.
Microsoft confirms yet another bug
Will it ever end? Microsoft confirmed several bugs already that plague users who have installed the January 2026 update for Windows.
Today, Microsoft confirmed yet another issue and this one appears more widespread than the others.
- The issue: Apps might become unresponsive when saving files to cloud-backed storage
- Support page: Link
- Affected systems:
- Windows 11: Version 25H2, 24H2, 23H2
- Windows 10: Version 22H2
- Enterprise: Windows 10 LTSC 2021, Windows 10 LTSC 2019
- Server: Windows Server 2019, Windows Server 2022, Windows Server 23H2, Windows Server 2025
Microsoft admits that the bug affects file operations, such as load or save, when cloud-storage is involved. Attempts to save files to OneDrive, Dropbox or other cloud storage services may trigger the issue. Similarly, opening files from cloud locations may also cause the freezes.
Microsoft writes:
For example, in some configurations of Outlook that store PST files on OneDrive, Outlook might become unresponsive and fail to reopen unless its process is terminated in Task Manager, or the system is restarted. In addition, sent emails might not appear in the Sent Items folder, and previously downloaded might be downloaded again.
The company says that it is working on a resolution. It does not have a universal workaround for affected users at the time of writing. While it has published a workaround for users who load Outlook PST files from cloud storage, it simply states that users should contact the application developer to learn about other access options.
I will update this article once there is a fix or a universal workaround. Keep you posted.
What the heck is going on at Microsoft? Is it just that there is so much spaghetti code that no one understands what is in the OS? Is it no or to little internal testing? Or and this is my belief they know the problems in the updates but dont care send it out fix it later, this way they meet thetime line for updates they dont care if its fubar.
They forgot to read the fine print. “AI makes mistakes, check important information” 🙄
Apparently they need to hire back people who debug the code.
Thankful–no issues here. And, as Martin recommends monthly, yearly, nearly every article–“make a full system image” before tinkering or updating your computer.
Yes, MS shouldn’t be issuing updates that create issues for users, but most veteran Windows users know by now, after years of the same old, NOT to UPDATE on Patch Tuesdays and have auto-updates turned off. In reality, one can forgo updating at least monthly; definitely, don’t update when the tech blogs tell you to. Big mistake!
The least we could expect is apologies. Never.
If Windows OS was a newcomer Windows 11 just wouldn’t make its way. Microsoft relies on OS market domination and from there on carries on from one fix to another. Users are beta-testers.
Once a great company, slop now replaces soft in the company’s name.
I can only think that Copilot is debugging Windows code. What else that could be?
