❗️ If your Windows 11 PC keeps running out of storage and you can't figure out why, it might not be your files. It might be Windows itself. A bug causes a hidden system file to grow without limit. The file is supposed to be a small log of which apps use your camera, microphone, and location, normally just a few megabytes. On affected PCs it never gets cleaned up, and users have found it at 70GB, 200GB, and in one case roughly 500GB. The worst part is you can't see it. Storage settings just show a huge "System files" entry with no explanation, so most people blame their photos or games and start deleting the wrong things. The folder itself is locked, so even File Explorer says access denied. Microsoft never listed the bug as a known issue. The fix arrived quietly inside June's optional update (KB5095093), and everyone else gets it automatically in the next monthly update, expected July 14. To check now, open Settings > System > Storage > System & Reserved. If "System files" shows hundreds of gigabytes, install the June update. If your drive is already too full to update, there's a Safe Mode workaround: rename the oversized file and Windows rebuilds a fresh one. 😂
