How to Add Another 90 Days to Your Windows 8 Trial

Extend Your Windows 8 Evaluation Period

Whether you want to try Windows 8 out  to see what it looks or you’re evaluating it for deployment across your business, you’ll appreciate the free 90 day trial of Windows 8 Enterprise Microsoft makes available. However, if 90 days is not enough, you can renew the trial period once it has expired with just one simple command. Just follow these steps:

  1. Launch the command prompt with admin permissions. The easiest way to get to the command prompt is to hit Windows + X and select Command Prompt (Admin).
    Select Command Prompt (Admin)
  2. Enter slmgr -reaarm at the command prompt and hit Enter.
    Type slmgr -rearm at the command promptAfter you hit Enter, you’ll get an alert which says “Command completed successfully.” Click Ok. 
    Windows Script Host will say command completed successfully 
  3. Reboot the computer. 

The corner of the screen should now show that you have a new 90-day trial. After that trial is expired, you’ll need to buy Windows 8, stop using it or wipe your computer and reinstall.

    I hope this works… I have it on my laptop that I hardly use and don’t feel like reinstalling Ubuntu just yet.

    Question, though: in the text you wrote ‘slmgr -reaarm’ but in the CMD box it shows ‘-rearm’ (only 1 a). Which one is correct ?

    I’ll try both.

    Thanks for the tip… have a great day :)

  2. Simon Says:

    The cmd is:>>>

    slmgr -rearm

    You got a typo as>>> slmgr -reaarm

    It didn’t work. However on my desk top in lower right corner it says “windows 8.1 build 9600″, which wasn’t there before. I still get a prompt to reactivate in word and excel
