Many of customers request information on querying hot fix information. They need a report on what hot fixes have been patched and what hot fixes they do not have installed. This article explains several ways to find this information.
1. Go to Windows Update Online.If the computer is connected to the Internet, you can go to Windows Update Online athttp://windowsupdate.microsoft.com. After scanning your system, the website will tell you what hot fixes you do not have.
2. In the %windir%, you can find a number of log files with names beginning with “KB” and followed by six digits, e.g. KB870764.log, KBxxxxxxUninst.log. KBxxxxxx.log – Contain installation information of the hot fix. If you can find this file and there are no errors in the log, then the hot fix in the file name has been installed. KBxxxxxxuninst.log – Contain uninstallation information of this hotfix. If you can find this file and there are no errors in the log, then the hot fix KBxxxxxx has been uninstalled from your system.In addition, you also can find uninstall folders of the hotfix in %windir% (with names like $NtUninstallKBxxxxxx$) and %windir%\$hf_mig$ (with names like KBxxxxxx). Generally you can uninstall the hot fix from that folder by running spuninst.exe.
