Delete $Windows.~BT and $Windows.~WS Folders is a batch file to simplify deleting these two folders that appear as hidden folders after a Windows Update. Also, see What Is the $Windows.~Bt Folder and Can I Delete It?

The $WINDOWS.~BT is a hidden folder created by a Windows Upgrade, typically done with Windows Updates. Other folders may appear including $GetCurrent, $WINDOWS.~BT, and $SysReset. The folders are hidden, and you can check for them by clicking View > Hidden items in File Explorer.

While you can delete the $Windows.~Bt, it's easier to ignore unless it's using a lot of space. We've seen the $Windows.~Bt folder take under 1MB but also use over 6GB.

Verify you don't have any Windows Updates pending by clicking Start > Settings > Update & Security > Check for Updates. We'd also wait a few days to a week to see if there's a large feature update coming.

Now that we've let you know that you don't need to delete these folders, you can use this batch file or you can use PowerShell.
