Without knowing the details of exactly what it does, it is hard to compare with what can already be achieved on XP anyhow. For example, CCleaner includes a capabilty to remove old Windows Update files from XP (and earlier).
Thank you for that Batch. It does work on Windows 8 but I had to run Disk clean-up twice for it to show. Same as getting rid of the windows old. folder. Took a while and no reboot needed. Cleared 660 MB.
