Warning: Messing with Windows folder is not advised. This may render your computer useless.c:\windows\system32\dllcache\contains backups of your system files. When, for some reason, system files are deleted/get corrupted, Windows copies the file from this backup.
When the file is not found in the cache, you are prompted for inserting Windows CD so file can be extracted from it.
Rather than deleting the files in the cache, you can do
sfc /purgecache, that way Windows will empty the cache in a more efficient way.
c:\windows\servicepackfiles\i386\This folder contains service pack uninstall files. When you installed SP1/2/3 over an exisiting installation of Windows XP, the uninstall option files are copied here.
If you do not want to have an option to uninstall SP later on, you can delete them.
c:\windows\driver cache\i386\You should not delete all the files, but only
driver.cab. But you would lose the functionality of automatically installing a hardware when you plug it in. Windows would ask you to insert XP CD instead.
c:\windows\inf\You should not delete files in this folder. This folder contains catalog inf files. These are necessary for PnP (Plug N Play) enumeration. When a new device is found, Windows checks inf files for a matching device driver then looks the driver up in the
c:\windows\sysem32\drivers.
