How to remove Windows 10 installation folder [Tip]

Windows 10 is the latest operating system from Microsoft. It comes as a free upgrade for Windows 7 and 8.1 users for the first year. The giant company has put a lot of effort in getting as much as machine to Windows 10. In latest report, some users found out that their Windows 7/8.1 PC downloaded the Windows 10 installation even when they didn’t reserve the upgrade.

This behavior doesn’t do any harm except it takes about 4 to 6 GB of your system drive. If you really don’t have a plan to upgrade to Windows 10, you can remove this downloaded folder and the upgrade offer all together to free up your disk space.

What is the $WINDOWS.~BT folder and how to remove it

If you are on Windows 7 or 8.1 and suddenly you see the system drive free space reduces without you install any new program, the $WINDOWS.~BT folder might be your suspect. This folder comes from Windows Update and it contains the bits of Windows 10. It can range between 4 and 6 GB depend on your system. As a folder, it can be deleted easily. However, first, you need to see it because it’s a hidden folder.

  • To show a hidden folder, in either Windows 7 or Windows 8.1, click Start then type “folder options.” Open Folder Options.
  • In Folder Options window, select View tab.
  • Scroll down the list you’ll see the section “Hidden files and folders.” Select “Show hidden files, folders, and drives.”
  • Click OK to apply the change.

After you set to show hidden folders, navigate to your system drive and you’ll see the $WINDOWS.~BT folder. Just simply select it and hit Shift + Delete to permanently delete the folder.

There is a catch though. Because the upgrade offer is still in your system, Windows Update will eventually download Windows 10 installation when it has a chance. And you’ll end up with the $WINDOWS.~BT folder again. To stop this, you’ll need to uninstall a update that gives you this offer.
