I'm running Windows 11 Pro 25H2, and everything was working normally until the computer was shut down last night. This morning, the taskbar no longer showed the time or weather, neither Wi‑Fi nor Ethernet was detected, and the display refresh rate kept resetting. Recovery tools produced errors, and previously created backups were no longer available. Windows also asked for a BitLocker recovery key when I tried to reset it, but I never knowingly enabled BitLocker and the PC is not signed in to a Microsoft account. The System settings page also fails to detect basic hardware such as the processor. Is there a way to repair this, or should I prepare for a clean reinstall?

If another user account exists on the computer, try signing into it. A damaged user profile can sometimes cause missing taskbar information and authentication-related problems, although it would not usually explain every hardware detection issue.
BitLocker can sometimes be enabled automatically, especially on supported systems, even if it was never manually configured. The recovery key may have been saved to a Microsoft account, printed, stored on a USB drive, or saved elsewhere during setup. If the drive is encrypted and no recovery key can be found, recovering the existing files may not be possible, so avoid formatting until you have checked every possible backup location.
The symptoms could point to a failing storage drive rather than ordinary Windows corruption. Check the drive’s health and run hardware diagnostics before reinstalling. If the drive is dying, reinstalling may only work temporarily and could make data recovery harder.
Try entering the firmware setup or BIOS and running its built-in hardware diagnostics. Check whether the drive and other hardware are detected there, and note the exact errors shown by the recovery environment. That will help distinguish a hardware problem from damaged Windows files.
If the data is not important or has already been recovered, create a bootable Windows USB and perform a clean installation. A tool such as Rufus can create installation media with options to avoid requiring an online account. Keep the computer offline during the first setup, then review OneDrive and other automatically enabled services afterward.
I’m mainly worried about the files on the drive, so I’ll check its health and investigate the recovery key before wiping anything.
