To solve the problem that Windows 7 cannot uninstall the patch package update

to ensure the computer runs smoothly, we need to update the system from time to time. Installing Windows Update is definitely one of the main ways we update our Windows system. Every once in a while, Microsoft will release a service pack, which contains a lot of individual updates, so you can download and install it at one time. These patches are even seen as an updated version of the operating system. Updates are released one by one before the patch package comes out. Although they are tested and stable, the software environment of each user is different, and not all updates work as expected. If an update does not work properly or the system is not working properly after installing an update. You can try uninstalling this update. The specific steps are as follows: 1. In the Start menu, click “Control Panel->Programs”. 2. Open “Programs and Features->View Installed Updates". 3. Now all installed updates will be listed. Check out the "Installation Time" column to find the most recently installed updates. Select the update you want to uninstall, right click and select “Uninstall”. (Note: After some updates are right-clicked, there may be no "uninstall" menu popup. Because the update files are in order, if they are associated with other updates or programs, they cannot be uninstalled directly.) Can be installed again after uninstalling 4. After the uninstall confirmation window pops up, press “yes  continue. 5. Don't worry, if you find it wrong later, you can still download and install this update again. Open “Control Panel\\System and Security\\Windows Update'; on the left side of the window, click “Check for Updates 

However, unless there is a good reason, Xiaoyi recommends that you do not arbitrarily uninstall the update. Because the problem can get worse and expose the computer to malware attacks.
