Have you every wondered why the Windows folder is growing and growing so big? I always create a new partition for a brand new Windows. However for Windows Vista I wondered what would be a good size. Windows XP has lived on a 21GB partition for many years without even coming close to the end and it will still live a long time. Thus I added additional 10GB to this size and installed Windows Vista on it. (Be aware that I always try to install programs on another much larger partition.) Oh dear! I should have added 30 GB instead of 10GB. Maybe the next time…

The main reason why Vista uses so much space is the WinSxS folder. There are lot of questions out there that ask if this folder can be deleted safely. After reading this technet article you should know the answer once for all.
