Normally download patches to your operating system is to solve problems. However, there are times when instead of fixing bugs, what they do is cause new ones can leave your computer completely unusable. If it were the case and work with Windows Vista , you can uninstall patches that have been updated the system and leave things as they were at first. However, this can not be done with them and that will depend on the amount of changes that have made those patches.

To access the Uninstall utility will continue this path:
Home > Control Panel > Programs and Features

• At the top left of the window find View Installed Updates. We click there.
• We will see a list of installed updates, and can sort them by name, date, program …
• Select the patch that we were looking for and click on uninstall, to remove it from Windows.
