Note: In Safe Mode, your system display and Desktop will look and perform differently than in Normal Mode. This is only temporary. To return the
system back to Normal Mode, we can simply restart the computer.
Once you are in safe mode I would suggest you to perform a system restore to an earlier point when the update was not installed – The System Restore tool uses restore points to return system files and settings to an earlier point in time. You can use it to
restore the operating system to a point in time in which you did not experience the issue.
Note: When you use System restore to restore the computer to a previous state, programs and updates that you installed are removed.
