I did the registry hack a month ago and it worked. I was allowed to run slmgr -rearm but this month when I tried to rearm I got an error. So I did the registry hack again and again ran the rearm command it appeared to work but on reboot I found the registry value back to 0 and I still had only 2 days to activate. Looks like Microsoft blocked the hack. Any find a work a round?

Did you get the Command complete successfully message after running the command?

I tried to extend my Visio but then it does not work even if I religiously followed the instruction.

Actually the Windows 8.1 Enterprise Trial only allows one re-arm, giving another 90 days, so the maximum you can run WIndows 8.1 for without re-installing is 180 days.

Question: does this work even if you’ve exceeded the 30 day trial? I’m guessing the answer is yes?

Situation: I installed Windows 7 on January 23. I used the “slmgr -rearm” command on February 23 to extend the trial 30 more days. However, I forgot to use the command again on March 23, and then didn’t use the PC for a few days. When I booted on March 26 my desktop background color was black, and there was a message in the lower right hand corner saying that this version of Windows 7 wasn’t genuine. I executed the -rearm command again and rebooted, and my desktop went back to what it looked like before, and the message was gone.

Just wondering what your thoughts are on this situation.

Ahmed March 28, 2016, 1:46 pm

It seems you successfully reset trial period, If you are not getting any message at right-bottom corner like “The copy of Windows is not genuine” or a popup message like “Activate Windows now, The activation period has expired…”
If you are thinking about license expired black screen then try to change the desktop background.

Yeah the hack really worked on my windows 8..1enterprise evaluation! It did give me an additional 90 days after running the rearm command but the second attempt gave me an error message that I can only run the command once. Whatever way your information still helps thanks so much.

I wouldn’t mind if you can send some useful DOS commands and their use to my email. Thank in anticipation.

Are there any real way out there that can tell us how to reset 8.1 forever, instead of just for a few months?
