You can also set to restore only the disk or partition where the system is located.

Component ",you can open the file \windows\inf\sysoc.inf with Notepad, and replace all the" hidden "characters in the file with spaces with the find/replace function. In this way, the hidden properties of all components are removed. After saving, run the Add-Remove program, and you will see many options that you didn't see before. Delete those components you don't need (remember to save them as sysoc.inf instead of the default sysoc.txt), such as Internat messenger service, fax service and Windows.

Settings "user name" \Local Settings\Temp folder (y: the partition where the system is located). Files in both locations can be deleted directly.

18. Clear the pre-read file: Windows
Although the pre-reading setting of XP can improve the system speed, after a period of use, the number of files in the pre-reading folder will become quite large, resulting in a longer system search time. Moreover, some applications will produce dead-chain files, which will increase the search burden of the system. So these pre-read files should be deleted regularly. It is expected that the file will be stored in Windows.
In the prefetch folder of XP system folder, you can delete all files under this folder.
