Hi ! Did you create a system repair CD or a system recovery drive?? Here are the ways that you can recover. My first choice would be to restore to a time before the update with a restore point! Read this by HTG! How to Create and Use a Recovery Drive or System Repair Disc in Windows 8 or 10

PS! Using a Recovery Drive or System Repair Disc

A recovery drive will normally not be necessary. If your computer fails to boot several times, Windows 8 or 10 will automatically bring up the advanced startup options, which allows you to troubleshoot and fix it.

If Windows can?t even bring up these tools, you?ll need the recovery drive, system repair disc, or a Windows 8 or 10 installation disc. Insert the recovery media into your computer and restart. Your computer should boot from the recovery media automatically. (If it doesn?t, you may need to change its boot order.)
