How To Uninstall Individual Windows Updates and/or edit the Windows Registry – ‘0x50’ stop error message


Although Microsoft test their updates there are times when an automated update results in system problems. As example of this is the recent system crashes caused by the August 12 updates. Problems with Windows updates on this batch resulted in some systems crashing with a ‘0x50 Stop’ error message.

Note: For more information about the August 2014 0x50 Stop error issue read Microsoft KB article

If you want to uninstall a particular update, either to trouble shoot your own symptoms or when prompted by Microsoft then this is how…

First open your Control Panel and Click on Windows Update


On the left click on View Update History


You will now see a list of installed updates.

If Microsoft are advisi9ng the removal of any update they will provide the KB (Knowledge Base) number and this can be seen in brackets in the update description.

To remove any individual update;

Click on Installed Updates at the top of this Window.


Find the update that you want to remove. Click on it


Click Uninstall at the top of the window to remove this update.


The update will now be removed and when complete you will most likely be prompted to restart your system.

In some cases you may be prompted to also make manual changes to the Windows Registry. To do this…

Click on your Start button and select Run or type Run on your start screen


Type regedit and press enter/OK



The Registry Editor will now open.


Making changes to the Registry is very low level and you should not make any unprompted changes as this could cause your system to malfunction. To prevent accidents before making any changes take a backup by clicking on File and Selecting Export then save a copy of your Registry to your documents folder.


You can now make any changes as advised by Microsoft or your technical support.
