Hello,
If you really think that this is the update that caused your system to react like this, you can try to uninstall the installed update. To do so
- Click on the Start Orb and type 'Windows update' in the search box
- select Windows update
- and at the bottom right of the Windows update screen you will see 'Installed Updates'. Click on it
- You will get all the updates made froma particular date. Uninstall the update that you think caused your windows to react like this
- Restart computer and see if it now works properly
Note: Please create a restore point before proceeding in these steps to make sure that if when you an update it makes your system unstable then you will be able to restore your computer and try a different method
