1. Delete the sample files in C:\Windows\Web\Wallpaper and my music/pictures/videos.

2. If you don't use the hibernation function, you can delete the hibernation file during the disk cleaning process. (2G space can be released)

3. You can transfer the page file. In my computer-properties-advanced settings, advanced-performance-advanced, transfer virtual memory to other places. If you have 1GB of memory, there will probably be 1.5GB files.

4. You need to clean the system frequently to recover, or if you think the computer is working well, you can disable it. You can make a lot of space.

If you feel trouble, use the vista optimizer. After installation, open the system cleaning function, there is a special vista slimming, but it is best to be careful not to delete it wrong.
