Windows 11 File History not working? What to check

File History is still in Windows 11, but Microsoft treats it as a legacy feature now. When it stops, it rarely says so. Here's what to look at.

Updated October 2026

1. Make sure it's on – and where to find it

In Windows 11, File History isn't in Settings any more. Open Control Panel › System and Security › File History. It's off until it's turned on, and it needs a drive or network folder to back up to.

2. Install the latest updates

After Microsoft's September 2026 updates, File History stopped creating or updating backups for some people. Microsoft fixed it in the October updates: open Settings › Windows Update and install everything waiting.

3. Check what it actually backs up

In Windows 11, File History backs up the folders in your libraries (Documents, Pictures, and so on). A folder elsewhere – D:\Accounts, say – is left out unless you add it to a library first.

4. Look for files it skipped

• Files that are always open. Check that files kept open all day – Outlook's data file is the usual one – are really in your backup, with a recent date. See backing up Outlook while it's open.
• Long paths. People have reported files in deep folders with long names being skipped without any warning.
• OneDrive files. Files that are only in the cloud (OneDrive's Files On-Demand) aren't on the PC, so they aren't backed up.

File History's Advanced settings has an event log that shows errors – worth a look if a file you expected isn't there.

5. Check the drive

File History can only back up while its drive is plugged in – and if the drive was replaced or reformatted, select it again in File History. If the drive is full, it stops too: Advanced settings can clean up older versions.

Test a restore

Whichever backup you use, the only proof it works is getting a file back. Every few months, restore a file you'd miss and open it.
