The $ Windows. ~ BT and $ Windows. ~ WS folders are located on the disk where you installed Windows, which is usually C. These folders are safe to delete but to view them you must first configure File Explorer properly. since they remain hidden by default.
These folders were created by the Windows 10 operating system when you upgrade your Windows 10 installation to the latest version. For example, these folders are created during the latest Fall upgrade Creators Update.
The $WINDOWS.~BT folder contains files from the previous version of Windows 10, which are required to go back to the previous version. The setup files used by Windows setup or the Media Creation Tool are stored in the $Windows.~WS folder.
If your system host has free space and you do not want to go back to the previous installation or version of Windows, you can delete these folders. Caution, once you delete these folders, you cannot go back to the previous version of Windows 10. But how can you delete with better safety of the $WINDOWS.~BT and $WINDOWS.~WS folder in Windows 10?
