Validating genuine windows
If you go to the store and buy a copy of Microsoft Windows you’re likely buying a standard retail license.
A retail license lets you install Windows on one computer.
Which is correct, because your activation has been transferred.
In the command prompt window type or right click - 7. NOTE: This method has worked for some people but not others.
OEM stands for Original Equipment Manufacturer, and this label is slapped onto software that comes pre-installed or packaged with a computer.
OEM copies of Windows come with a license that only allows Windows to be installed on the machine the manufacturer shipped.
This is not surprising when you think about it; if you could simply remove your activation, there would be no point to the OEM license.
There are cracks, of course, but these are not difficult for Microsoft to counter over time by releasing new updates.
