    How to prevent $Windows.~BT file from coming back?


    I have a $Windows.~BT file on my c drive (Windows 10 Trial version, Partitioned on a Macbook via Bootcamp) that takes up a lot of space (can easily get to 17gb+ if left undeleted). Normally I can't delete it via the recycle bin so I did some googling and found that you can do so by entering the following in order on the command line:

    takeown /F C:\$Windows.~BT* /R /A

    icacls C:\$Windows.~BT*.* /T /grant administrators:F

    rmdir /S /Q C:\$Windows.~BT\

    However every time I delete it and restart the computer, the file comes back after 10-20 minutes and quickly starts eating space again. How do I delete this file permanently? Apparently the file is used when upgrading from Windows 7/8 to 10 but this is a mac so I'm not sure why I even have this file (I did have a previous partition of Windows 10 which I deleted) ? I also had a windows.old file which I deleted via disk cleanup.

    No, not just from 7/8 to 10. It's also used to update from one version of 10 to the next. What version of Windows 10 did you install in Bootcamp? The current version is 1803, run Winver to find out which you have installed.

    If you installed a previous version (1709 or earlier) then windows update will be attempting to download the install files and automatically update you to version 1803. The easiest way to stop this would be to install version 1803 yourself so there's nothing to upgrade. Alternatively, stop deleting the files and let windows update complete the job of upgrading your Windows.

    What exactly did you mean by a 'Trial version'? Where did you get it from? Note that it against the EULA to run an unlicensed copy of Windows, even in bootcamp.

    I see, that probably explains it, I'll try to update Windows.

    Also I meant my Windows 10 is unactivated, i.e. I downloaded the ISO from Download Windows 10 and installed via Bootcamp without having an activation code.

    Ah, that makes sense,. There is a 90-day trial version of Windows 10 Enterprise so I just wanted to be clear you weren't talking about that. It would seem likely that you downloaded the ISO a while ago, before April 30th this year when 1803 was released. If you download it today you will get the ISO for version 1803.

    If you installed 10 Home or Pro using that ISO and want to continue using it legally you'll need to purchase a licence.
