Can I buy boxed Windows and Office from my hands?

Question

Microsoft

Will the license code be activated if it is already registered on some other PC? How does all this happen?

Answer 1

I think a phone call to the Microsoft office is indispensable.

Answer 2

It is possible, but not the fact that it is activated via the Internet, so you have to do it through the telephone activation system.
If de jure, then the previous owner deletes the installed copies of the software and gives you the key and media, the EULA conditions are met.

Answer 3

If the previous owner activated 1-2 times, then there are no problems, even via the Internet it can be activated, there was one time 2-3 attempts.
If it does not pass, the system will offer to call the free federal number 8-800 (Russia) or direct Moscow. Again, there are options. If there were not too many activations, the robot aunt will ask “How many computers have this software installed on? Press "1" if the software is installed on one computer." Press "1", and she dictates the answer code to you.
If there were a lot of activations or the license was canceled, then you will be connected to a live aunt with an even greater accent than the robot, and if you prove that the software is yours and licensed, and did not violate (say, this is not a key from the Internet with 1000 activations ) will dictate the code.
In a normal situation - 100% activation through the robot.
