Win11 Show hidden items checkbox in File Explorer toolbar disappears after system restart

Those File Explorer choices are per-user preferences and should normally survive a restart. Microsoft’s supported locations are View > Show > Hidden items and View > Show > File name extensions, so the reset suggests something is rewriting your profile rather than the options being session-only. Enable both, close Explorer, reopen it, and recheck before restarting. If the device is work-managed, ask IT whether Group Policy or MDM enforces Explorer settings. Otherwise, disable shell customizers or cleanup utilities and perform a clean boot to identify a program resetting them at sign-in. Create a new local user and test there; if the settings persist, the original profile is damaged. If they reset in every profile, install current Windows updates, then run DISM and sfc /scannow from an elevated Command Prompt. Avoid repeatedly editing registry values until policy and profile scope are known, because the same process may overwrite them agai
