Hi. I'm wondering if someone would be kind enough to answer a question that I have. Recently, I added a new piece of hardware to my gaming PC that was running Windows 7. All of a sudden, Microsoft comes back telling me that my operating system was not valid. I couldn't get them to accept my legal registration key again. Talk about being mad and frustrating. So, I had to go online and purchase another key again so I could reinstall Windows 7 and, thus, upgrade to Windows 10.
Now, I'm think of adding a new graphics card to this PC that I also run TrainSimulator on, but I'm reluctant to do so because of the problem that I had with the other one. I'm wondering why Microsoft does this and why there isn't any way of getting to them and telling them that I am running a legal version of their operating system and to cut out the nonsense. Even using the phone method of trying to reestablish my reg key didn't work. Has anyone else out there had the same problem and how did you deal with it.
