I just did this and my computer is running faster. I was lucky, this patch killed your computer.
Tech giant Microsoft has recommended that an update released in the latest Patch Tuesday be removed, after users reported incidents of the "blue screen of death" after installation.Microsoft released two critical security updates and others rated as "important" for Windows and Internet Explorer as part of its latest round of Patch Tuesday updates.However, a number of Windows 7 users have reported issueswith security update 2823324, which is part of security bulletin MS13-036.MS13-036 was meant to fix three privately disclosed flaws and one publicly disclosed flaw in an NTFS kernel-mode driver related to the elevation of privileges when a user is logged in. However, once installed, security update 2823324 -- part of the bulletin -- may produce a "STOP: c000021a {Fatal System Error}" problem for users. The error occurs early in the startup process, and no Memory.dmp file is created.As a result, Microsoft has temporarily pulled the patch from its security bulletin while the issue is being investigated.
If you have this patch, this might be a good idea.
