After I updated KB5124008 recently, file history was disabled, and many users reported being affected. Some netizens said they had spoken with others and confirmed that other users had encountered similar issues, but they had not yet confirmed that KB5124008 was the root cause. https://learn.microsoft.com/zh-tw/windows-insider/release-notes/experimental/preview-build-26340-9502 https://learn.microsoft.com/zh-tw/windows-insider/release-notes/beta/preview-build-26220-9492 Microsoft released version 26340.9502/26220.9492. These two URLs contain fixes for the issue where backups using [File History] unexpectedly fail and display the error message "No available disk drive found". So happy What is Windows 11 Insider Beta? When will all these features be released to everyone?
