Windows 11 update gets stuck and rolls back

Do not keep forcing the same restart loop. First find which part is failing: download, install before restart, reboot phase, driver handoff, disk space, or firmware/security state. One update error code plus a storage check is more useful than ten repeated restarts.

Start here:

1. Plug in the PC and make sure C: has at least 20-25 GB free if possible.
2. Unplug non-essential USB devices and docks. Leave only keyboard, mouse, display, power, and network.
3. Open Settings -> Windows Update -> Update history. Note the failed update name, KB number, and error code if Windows shows one.
4. Open Settings -> System -> Storage. If C: is nearly full, use Settings to remove temporary files. Do not delete recovery partitions.
5. Run Settings -> System -> Troubleshoot -> Other troubleshooters -> Windows Update once.
6. Restart and retry the update one time. If it rolls back again, stop repeating the loop.

If Windows does not show a useful code, search Start for Reliability Monitor, open View reliability history, and check the red X on the update day. Look for Windows Update, Setup Host, driver, or disk-related entries.

Do not delete recovery partitions, clear TPM, turn off BitLocker, or reinstall Windows just because one cumulative update rolled back. Those are later branches, not first moves.

If you ask for help, include the failed update or KB number, error code if present, free space on C:, whether a dock/external drive/printer/capture card/USB hub/SD card was connected, and whether Reliability Monitor names a driver or setup failure. Hide account names, serial numbers, recovery keys, and private file paths.

Stop here if the PC enters a boot loop and does not return to the desktop, BitLocker asks for a recovery key, the Windows drive reports SMART or disk errors, C: has almost no free space, or a BIOS/firmware update happened right before the Windows update problem.
