What happens after the trial period of Windows has expired? [duplicate]

Windows 7 activation period

I installed Windows 7 Home Premium 64-bit on my laptop a few days ago. Today I got a message in notification bar saying that I have 25 days remaining to register windows with the product key.

Now, I do not have a product key at all. I want to ask what happens after 25 days if I do not enter the product key at all.

  • Will Windows stop booting?
  • Will I not be able to use Windows at all?
  • Will I have to install some other OS or re-install Windows?

Windows will shut down forceably after 1 hour. Your background will go black, and you will be constantly reminded that you are on an illegal copy of Windows.


After a month when you get the "Activate Windows Today" message you can open a command prompt (as administrator) and type "slmgr -rearm" (without the quotes). This will extend the trial license for 1 month. You can do this three times.

Don't you have a restore disk/partition?
