I recently installed Windows 7 on my tablet. It, so far, has been ok - not as bad as Vista or XP. I was trying to see how much room I had on my hard drive to try and do a dual boot Hackintosh tablet. I have hardly anything on the tablet (Windows 7 and Adobe Illustrator plus a few files of my own that take up maybe a few hundred MBs of space). The computer tells me that I have 27GB free out of 68.4GB! WTF!!!! Snooping around a bit I find a folder called Windows.old which has a "size" of 25.2GB and "size on disk" of 20.9GB (presumably all of Windows fu****' Vista and all the programs I had previously on the computer).
Anyways, I know this is the Mac thread so I just wanted to complain here and say that Microsoft still has so much to learn from Apple.
By the way, anyone know if I can just delete this huge folder and get back half of my harddrive? Is there some way I can reinstall everything and not have this happen.
