Where is that batch file posted / what is it for?
All of that mysterious stuff on that drive perplexed me. I had cleaned everything, disk cleanup on all installed HDs multiple times as admin, as well as doing the chkdk, and nothing was found.
Just to make sure, I opened a cmd prompt during install, ran diskpart, cleaned the drive, converted to gpt again, created the partition, and then formatted the drive without the quick option. Took around 20-30 minues to finish, but now I have some peace of mind that the drive is not malfunctioning or going on the fritz in any way.
Right. My drive said 120+ GB were taken up by almost 66K files. The problem was that I could only find the original ~30GB of files - nothing hidden or anything, since I keep the setting to show hidden files enabled all the time.
I have no idea what was going on. But I am re-installing everything now after installing 4971 and then taking the Update to 14986, optin to leave UUP enabled. Cool thing - as soon as I enabled IP Fast ring, the update was available to download.
