My question: I noticed in two areeas.1- In the actual programs and features Microsoft downloads a lot of security upgrades, that some are years older and do clutter and take space. Can these updates,the older and not updated ones be removed without causing any major probems? 2- In the smae manner, under C: Windows folder - There is a large group of files that beging with the file name of $NtUnistall... and other files with KB9XX (the numbers differ) these are Text documents and do not know how they get there...can these also be deleted without causing major problems?John1 person needs an answerI do too

If your PC is behaving properly you can remove those hidden Windows hotfix backup files that begin with $NTUninstallKB from the WINDOWS folder. Be aware that once they are removed you will not be able to uninstall the updates that they represent.There are two ways to do it:1. 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.2. 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.
