About this tag
The $WINDOWS.~BT folder is a hidden system folder created by Windows during feature updates or upgrades, typically containing installation files like install.esd. Users often encounter this folder after updating Windows 10, and it can occupy significant disk space. Common questions include how to prevent its creation during custom installations, how to locate the install.esd file within it, and whether it is safe to delete the folder to reclaim space. While deletion is possible, it may affect the ability to roll back updates. This tag covers troubleshooting and management of the $WINDOWS.~BT folder in Windows environments.
