A note from Luke. Reference material, not a story. I had an AI research and draft this one.
Disable it #
Documented by Microsoft as the actual switch for this notification. Run from an elevated command prompt.
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsBackup /v DisableMonitoring /t REG_DWORD /d 1 /f
If a notification is already sitting in Action Center when you set this, it clears itself at 10 AM the next morning rather than immediately.
Separate, older mechanism, worth doing alongside the registry value.
- Control Panel → Security and Maintenance → Change Security and Maintenance settings.
- Uncheck “Windows Backup” under Maintenance Messages.
What doesn’t work #
Settings → Personalization → Start → “Show account-related notifications” is the fix most commonly suggested online. On the Microsoft Q&A thread about this exact notification, multiple people report toggling it off and getting the “Action advised, back up your PC” banner again anyway. Don’t stop there.
Background #
Per Microsoft’s own documentation, this notification has existed since Windows 7. It fires at startup starting seven days after the OS is installed, and immediately whenever a drive is plugged in, until Windows Backup is configured or the DisableMonitoring value above is set.
Bottom line #
Set DisableMonitoring to 1 under WindowsBackup in the registry, uncheck Windows Backup in Control Panel’s Maintenance Messages, skip the Personalization toggle since it’s reported unreliable on its own.
