i have been checking out how to go about formatting windows and starting again as i have accumulated a lot of sh*t i don't need while getting to know my way around my comp and the big bad internet. i have just downloaded the magic jellybean winkey finder as i didn't get the install disc when i bought my laptop, but i have just came across a windows installation backup file while looking about for stuff i don't need. it is in my d drive as i have a partition, behind which i usually keep all my media and such. is this file a backup of my windows xp by any chance before i go any further ?
