Answer
Back up important files, open Windows Update, install available updates, and restart when prompted. Windows 10 support ended on 14 October 2025, so plan a supported-device upgrade.
Check the starting state
Before changing Windows 10 updates, back up important files, connect power, confirm free storage, and record the current version plus any KB number or error code. Keep the current state, exact message, and any recent change available so each result can be compared.
Choose the supported path
Separate a normal pending restart, failed quality update, driver update, and Windows 10 end-of-support planning instead of repeatedly clearing update data.
Check the support status
Windows 10 no longer receives free security fixes from Microsoft. Confirm whether the PC can move to Windows 11.
Back up important files
Save current work and back up files you cannot replace before a feature update or operating-system upgrade.
Check for updates
Open Settings > Update & Security > Windows Update and select Check for updates.
Restart to finish
Install offered updates, connect the PC to power, and restart when Windows requests it.
Verify the result
Update history reports success and a second check completes after restart without losing files or recovery access. Repeat the original task once more after reopening the relevant app, connection, or Windows session so a temporary result is not mistaken for a fix.
Troubleshoot Windows 10 updates
If the same KB and code return, startup enters recovery, device encryption requests a recovery key, or the device cannot move to a supported Windows release, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
