: I have hundredsnof K0000 security notices on my system dating back to 2007. Can I safely delete them?

Please explain what are ' hundredsnof K0000 security notices ' ?Are you referring to updates being offered ( KBxxxxxx )? If the system has not had any updates installed since 2007, then your system is now Owned by ( in possession of ) someone other then yourself and you will need to reinstall whichever edition of Windows that is currently installed to regain control of it.

Folders that have uninstall as part of the name (for example $NtUninstallKB282010$ which reside in C:\windows (hidden folders) are Window Hot Fix Update folders/files) can be safely deleted (providing you never wish to uninstall the updates). I would recommend leaving these folders for a period of at least a month to make sure the update is working correctly.These updates can be deleted individually or in multiples. To find out more about the update/s go to:http://support.microsoft.com/kb/XXXXXXNB: XXXXXX = the actual number not including the "Q" or "KB"Once you have deleted the uninstall folders/files, then go to Control Panel, Add/Remove Programs. Select the matching Windows Hotfix Title relating the update folder/file you have just deleted and select remove. You will get a Windows error. This is because you have deleted the uninstall folder/files. Just choose OK and the entry will be deleted from the Add/Remove Programs Listing.Do NOT delete the $hf_mig$ folderTidying up after installing SP2http://aumha.org/win5/a/sp2faq.php#afterand/orXP SP3: Post Installation Cleanuphttp://aumha.net/viewtopic.php?f=62&t=33827Please note this is only for Windows XP and does not relate to Vista or Windows 7TaurArian [MVP] 2005-2011.
