We already know that by default installing Vista capacity requires 7GB~8GB of space, for users with hard disk space, we can manually remove Vista unnecessary components in Windows XP. Because the components to be removed in Windows XP are not in use, we can easily remove them.
Before deleting a file, it is recommended that you back up the system before you go to Vista without exception and then delete the backup completely. For example, you can delete D:windows/web/wall/paper (own wallpaper, unwanted delete, Occupy 45.5MB), D:windows/system32/driver/storefile/repository ( window with drive backup takes up 1.03GB), D:windows/win/sxs/backup (backup files, Occupy 354MB), d:users/public (all user public folders, occupy 217MB), d:windows/ System32/driverstore/filerepository (drive file, Occupy 1030MB).
Tip: Vista is formatted with NTFS, if you cannot delete a file at Windows XP prompt, right-click the file you want to manipulate select Properties, and then click the Security tab to set the current user's permission to delete files to Full control. Back up and Restore Vista on Windows XP.
Although the speed of installation of Vista has greatly improved, but with your own installed software + Automatic system updates, the installation of the entire system is more time-consuming, and because of the new system, many applications and Vista also have compatibility issues. Therefore, it is necessary to back up the vista after it has been installed. Now we have a dual system installed. Because of the size of Vista, it is recommended that you use the Ghost32 8.3 version, which produces a mirrored file larger than 2GB.
Run Ghost32 after you enter Windows XP, click local→partition→to Image, then select 2nd partition (install Vista partition), and then back up the partition as Vista.gho (Figure 5). This will restore vista later. Ditto, after you start Ghost32 in Windows XP, click Local→partition→from Image, and then select the prepared mirrored file to revert to the second partition.
