I think what happened is that Windows has a cleanup policy for stale profiles. If a machine hasn’t been logged into for a long stretch (like a year in your case), the profile can get purged either by corporate group policy settings or by the OS itself during maintenance. It’s basically trying to free up disk space and keep things tidy. The good news is that your data should still be safe if it was redirected to network storage (like OneDrive or a roaming profile), but anything stored only locally on that machine is probably gone. If you want to avoid this in the future, I’d suggest logging in periodically or checking with your IT team about the retention settings they’ve got in place. Hope that clears things up.
