After Windows attempted a System Restore, the message in my attachment appeared.
If someone can suggest a way to complete my System Restore, I would appreciate it.
(I am using a Dell 3847 computer with 12 GB of memory and a processing speed of 3 GHz.)
The reason I want a System Restore is because my display started intermittently to jitter and blur. Windows Defender scanned my computer completely and said that "no action is needed."
Before attempting the System Restore, I turned off CCleaner and Windows Defender.
