I have all if the install/uninstall folders and logs since I installed XP.I am sure that the latest set of Windows Updates are working.Is there a problem with deleting off of the old folders/flies and logs using CCleaner?If not all, can I at least delete those files older that the SP2 install date?What problems can I incur after doing the cleanup?I would assume that the answer would apply to MS Office updates also.Thanks,caveman881 person needs an answerI do too

If your PC is behaving properly you can remove the Windows hotfix hidden backup files that begin with $NTUninstallKB from the WINDOWS folder. There are two ways to do it:A. Manually, but copy the folders to a CD/DVD first to allow their restoration should a fix need to be later removed. Now delete them from the \WINDOWS folder but leave the orphaned Add or Remove Programs entries intact. Only delete the $NTUninstallKB folders that relate to fixes not those for applications like Word, WMP, etc. Also, DO NOT DELETE THE $hf_mig$ folder.B. My preference is to run a script which additionally removes the corresponding entries in Add or Remove Programs. Once they are removed by the script, they cannot be restored. Download, extract and run this little scripthttp://www.dougknox.com/xp/utils/xp_hotfix_backup.htm Create a system restore point first just in case anything goes wrong during the registry updating.
