I'm running Windows 11 Pro 25H2, and everything was working normally until the computer was shut down last night. When it was started 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 return errors, and previously created backups are no longer available. Resetting Windows asks for a BitLocker recovery key, but I never intentionally enabled BitLocker and the PC isn't signed in to a Microsoft account. Windows also fails to show basic hardware details such as the processor in System settings. Is there anything else I should try, or is a clean installation the only realistic option?

If another user account exists on the computer, try signing into it first. A damaged user profile can cause missing taskbar information, settings problems, and authentication-related errors, even when the underlying Windows installation is still usable.
The storage drive may be failing, either physically or because its file system has become badly corrupted. Check the drive’s health and run hardware diagnostics before reinstalling. A reinstall may only be a temporary fix if the drive itself is failing.
Protect your files before making major changes. If BitLocker encryption is active and the recovery key was never saved, data recovery may not be possible through the local account. If there is nothing important to preserve, create a bootable Windows USB with a tool such as Rufus and perform a clean installation. You can configure the installer for a local account and no internet connection, then remove or disable cloud-sync software if you don’t use it.

Do you mean the physical drive could be dying, rather than this being only a Windows software problem?
