Windows 7 Safely Delete $UPGRADE.~OS and $WINDOWS.~BT in C:\?

[Dave McKeen]

Hello! I just noticed I have $UPGRADE.~OS and $WINDOWS.~BT in the root of my C: drive. The former "size on disk" is 264 MB and the latter is 3.3 GB. The latter has tens of thousands of files and thousands of folders.

I ran Disk Cleanup on the drive. It removed a lot of files, but these two folders remain. I can't find anything on them on-line or in a search here. Can I safely delete them?

Thanks very much,

- Dave McKeen

How many hard drives do you have ? If more than 1 ssd/hdd was in your pc and you had your documents, etc. on a 2nd drive prior to the 8.1 upgrade, you'll have alot of weird issue's like this. If this is the case, you're better off unplugging the 2nd drive, doing a clean 8 install, followed by running Windows Update until none are found. Then reinstall 8.1 from the Store, re-run Windows Update until none are found. Then get the updates for the Modern app's, open the Store and in the Charms Barr click on App Updates and then Search for Updates. Install any and shut down your pc. Replug in the 2nd hdd and start Windows. Now point Windows to those folders.

O.K. Try this type Disk Cleanup in 7's start menu search box, right-click on Disk Cleanup up top and click on Run As Administrator. When it's done running and a Window pop's up click on every box in it and click on OK. Now go back and see if you still see those folders. You may want to do a bios update,too. Your's is a beta version that's over 2 years old.

Did you re-install the programs on your 2nd Vertex 3 after the new install of Windows ? If no, you'll need to reinstall them again. I had the same ssd, until last month when I upgraded to a 256gb. I also have the same Blu-ray burner.
