hi all - I just bought a mini computer with 32GB drive [19GB free + 6GB recovery partition] thus approx. 7 GB for the Win8.1 install --- after doing Windows Update, just once, now I'm down to 8GB free.

This seems rather excessive since the Win Update downloads were less than a Gig - I've checked with Disk Recovery to see what I could delete, but only found about 400MB of Windows Update backup files. I thought at first it was just a reporting error, but after rebooting a few times and 'trimming', I'm still at 8 GB free.

any ideas what mushroomed!, and how to free some more space?
