Keys not working on PC

[BobLfoot 301]

You're about to enter the "Twilight Zone" as you read through this post.

1. Recently restored a Macrium Image to a Dell PowerEdge Server

2. After booting the image Keys c, v, h, i, o & p would not type and enter into the login boxes either from USB Keyboard or On Screen Keyboard

3. Restored another image to the Server and it booted normally all keys working.

4. Returned to restoring image 1 and keys malfunctioned.  But when trying to use OSK noticed that the "Windows" key was showing presses.  

5. Tapped the "Windows Key" on the USB Keyboard and the OSK no longer showed a pressed "Windows Key"

6. Keys c, v, h, i, o & p now worked as expected.

Never seen this in 35 years of PC work and thought it was worth sharing.
