Windows 7 slmgr
I do a lot of virtualization both at home and at work. Several times I’ve needed a way to extend the activation period of Window 7 because I’m not done w/ a project.
Enter Windows Software Licensing Management Tool.
If you open up a command prompt by right clicking it and selecting, “Run as administrator” you can run the slmgr.vbs command such as…
This can buy you some valuable time before you delete that VM and start on something else. This command ‘rearms’ the activation period and I believe you can do it for a total of 3 times before it stops working. Also, try adding a /? on the end to see a handy dialog box w/ the other available options.
