When I had computer problems back in the old days (circa 1999), I used to call some computer geek business and have them come out and fix it. Nowadays, I just go to YouTube. There is always some helpful guy or gal out there who has learned a few tricks and loves to share them.
This morning my wife came to me, a little panicked, complaining that her laptop’s screen was black with a message telling her that her copy of windows was not genuine. I had no idea what to tell her, but I did know where to look. First, I opened up my good, well-behaved laptop and Googled, “black screen windows not genuine.” I was expecting some forum posts to come up, but instead I saw my old friend, YouTube. Someone had exactly what I needed. The above video tells how to fix it. I was done in 5 minutes, including the time it took to watch the video.
Just in case the video gets taken down at some point in the future, here are the directions in plain English. First, click on the Windows icon at the bottom left. When you see the search box, type cmd. Then, when cmd is underlined, click on that with the right mouse button and choose, “run as administrator.” When the command line box opens up, type this exactly: SLMGR -REARM. Then hit enter. Next, type EXIT and then restart windows. Ta da! At least, that is how it worked on my wife’s old Gateway laptop.
Good luck! And remember that YouTube has many friendly experts who give away their information for free. It’s not just for cat videos…
