Hello Carmella Cullen,
I understand how disruptive this is, especially when the update runs for hours and then asks for the BitLocker recovery key.
For now, please avoid forcing the laptop off again. In Settings > Windows Update, pause updates to cancel the current attempt and prevent another automatic retry.
Then open Settings > Windows Update > Update history and provide:
- The exact error code shown for KB5101684
- Your Windows version and OS build from
winver
The failure code will help distinguish an update-component problem from a device-specific installation failure.
