That sounds a lot like a temp directory created Microsoft's installer, in which case it's harmless.
Installers for a number of Microsoft products will create a randomly-named folder at the root of the drive with the most available free space*. The contents of the installer are extracted into this directory. These contents include graphics, language-specific text (the 1025-3082 folders probably correspond to LocaleIDs
), and MSI installer packages.
Look for a file named SetupUtility.exe
in the folder. If it exists, right-click on the file and select Properties
from the popup menu. In the Properties window that opens, check the Digital Signatures tab. If it is a Microsoft product (and therefore likely safe) it should have a digital signature from Microsoft Corporation like this:*which, by the way, contradicts Microsoft's own developer guidelines </rant>
