Microsoft admits it broke a Windows 11 backup feature — but it's now fixed

Microsoft has acknowledged a bug in its Windows 11 September update that rendered a backup feature, File History, unusable for some users. The issue, which was widely reported since the update's launch over two weeks ago, affected the ability to create or update backups using File History. Microsoft has now released an optional update that reportedly fixes the problem, although a full resolution of all File History issues has not been confirmed.

The optional update is essentially a preview of the upcoming October update, scheduled for release on October 13. While some users have reported that File History is now working after installing the optional update, there remain concerns over the "Run now" functionality and synchronization issues. Microsoft has faced criticism for the frequent bugs in Windows 11 updates, prompting some users to delay updates.

Analysts suggest that Microsoft must improve its quality assurance and testing processes to ensure a more reliable Windows 11 experience in the future.
