A Windows 11 Bug May Be Quietly Eating Hundreds of Gigabytes of Your Storage
Microsoft says the June preview and July updates fix a Windows 11 bug that can bloat a system file to 500GB.
- Microsoft released a fix for a Windows 11 bug in the CapabilityAccessManager.db-wal file that could consume up to 500GB of disk space. The update addresses the file's failure to compact properly, preventing unexpected storage loss.

- If the "System & reserved" category shows no more than three dozen gigabytes, the system is likely unaffected. Microsoft advises users to avoid manual deletion, as some users reported losing WiFi functionality after attempting to remove the file.
