Windows 10: Windows unable to activate

My Window 11 isn't working properly. All the Microsoft Windows icons are black and white. This is the error message 0x8007007B found in the systems area it initially said "activate windows" and when I click on the link it doesn't respond. Yesterday I performed a memory verification. not when I try to open the settings to see the systems info the window closes immediately upon opening.Now when I open my screen a new message pops up "The instruction at 0x00007FFC7823C003 referenced memory at 0X0000000...10. The memory could not be read. Help!!! Please

Unable to Activate Win 8

I got Win 8 isntalled on my file server, but I am unable to activate it with the key. Says the key is invalid. Since I work at microsoft I got a retail version from the employee store. I have been doing some reading, and to be able to activate Win8 with the key there needs to be a previous version of Windows installed for it to work. WTF, so you can't do clean installs?

And the box says nothing about Upgrade version. Straight Windows 8 Pro.
