Windows 10 Suddenly lost the option to rick click manage and also sleep mode

[adriancal]

Hi All,

For some reason, I can't fathom. In the last week, I can no longer right-click on "This PC" and select manage. I now receive a User account control pop-up telling me that the app has been blocked for my protection.
Additionally, the option to select Sleep has also disappeared when I click on power. There may also be additional functionality that has gone that I have yet to discover.

Does anyone have any idea what is going on here. I've never had a problem like this in the past.

Thanks

A

Just noticed I am also now receiving the message "Display Driver Failed to Start"
