There is a folder named $WINDOWS.~BT on the root of my C: drive. It is a hidden folder and is 75 MB in size.
What is its purpose? Is it safe to delete it?

This seems to be Windows update logs & files.
It includes files to upgrade Windows, and also, once you do upgrade, the old OS goes into that folder
It should be perfectly safe to delete it, as long as you don't want to upgrade or downgrade Windows.
However, you can't do it the normal way.

Instead,
a) Press Windows key + R
b) Type: %windir%system32cleanmgr.exe
c) Hit Enter on your keyboard
Edit: This method seems to only delete some things in this folder, some may be left over. See the other answer for a more complete removal method, though that isn't perfect, either. Additionally, this may help: How to delete trustedinstaller files on Windows 8

Well, I got as much as 4.4 GB in it. Looks like Windows 7 is “pre-loading” Windows 10, though I never agreed and explicitly disabled it..
CleanMgr.exe mentioned in the other answer deleted some stuff, but mostly refused. Manual install in File Manager also failed, because of lack of rights (even with full admin privileges), lack of ownership (owned by “TrustedInstaller”), etc..
Here is a brief receipe, to help yourself from windows command prompt with administrator rights:

The $WINDOWS.~BT and $WINDOWS.~WS folders are associated with the Windows 10 upgrade process. They may appear on either Windows 7, 8, or 10, using gigabytes of disk space.
These are hidden files, so you’ll have to show hidden files in Windows Explorer or File Explorer to see them.
On Windows 7 and 8

During the free Windows 10 upgrade period, Windows 7 and 8 automatically downloaded Windows 10 installation files and stored them in the $WINDOWS.~BT folder. When you agreed to the free upgrade, it could start quickly using the already downloaded installation files.
The free upgrade period is now over, so you couldn’t use these files to upgrade to Windows 10 even if you wanted to.
Microsoft should eventually remove these files if they’re still present on any Windows 7 or 8 systems, but they may still be sticking around for now.
On Windows 10
RELATED:What is the Windows.old Folder and How Do You Delete It?
On Windows 10, the $WINDOWS.~BT folder contains your previous Windows installation. These files are used to downgrade to a previous version of Windows, or a previous build of Windows 10.
It’s similar to the Windows.old folder, which contains files from your previous Windows installation. In fact, you’ll see both folders after upgrading to Windows 10–both Windows.old and $WINDOWS.~BT folders.
It also contains log files. For example, if you download and run the media creation tool, it creates a $WINDOWS.~BT folder with a few setup log files. That media creation tool also creates a $WINDOWS.~WS folder that contains most of the Windows setup files.
Windows should automatically delete these files to free up space after ten days in the Anniversary Update, or thirty days if your PC hasn’t upgraded to the Anniversary Update yet.
Can You Delete It, and How?
RELATED:Is It Safe to Delete Everything in Windows’ Disk Cleanup?
Warning: If you choose to delete the $WINDOWS.~BT folder on Windows 10, you won’t be able to downgrade to the previous build of Windows 10 or previous version of Windows your PC had installed. The option to roll your PC back at Settings > Update & Security > Recovery will vanish. However, Windows 10 automatically deletes these files after ten days anyway.
If you want to delete these files, though, you can. But you shouldn’t just delete them the normal way. Instead, you should use the Disk Cleanup tool included with whatever version of Windows you’re using.
Introduction to microeconomics lecture notes pdf. To do so, access the Disk Cleanup tool and click “Clean Up System Files”. Check the following items in the list and remove them:
Click “OK” to remove the files.
If the $WINDOWS.~BT folder is still present afterwards, it likely just contains a few spare log files–or now-useless setup files on Windows 7 or 8–and you can try deleting it manually from File Explorer. Just right-click it and select “Delete”.
