I bought my new computer a few weeks ago. I have 2 harddrive with 60 GB (C:) and 1TB (D:). Now my first problem was to free up some space on C as when I bought it with only windows installed there were just 15/20 GB free... I followed some instruction and I changed the settings of the page file, the restore points and so on and I arrived to 30 GB.
Today I upgraded my Windows from Home to Professional and when i checked my C drive the space became suddenly 15 Gb. Anyone know what happened and how can I recover my space agan?
