How to Use Windows 7 Without Activation

Use Windows 7 Without ActivationMost of you might be aware of the fact that it is possible to use Windows 7 and Vista for 120 days without activation. This is actually possible using the slmgr -rearm command which will extend the grace period from 30 days to 120 days.

However, in this post I will show you a small trick using which it is possible to use Windows 7 without activation for approximately an year! Here is a way to do that.

Step-1: Go to “Start Menu -> All Programs -> Accessories“.

Right click on the “Command Prompt” and select “Run as Administrator“. If you are not the administrator, then you are prompted to enter the password, or else you can proceed to step-2.

Step-2: Now type the following command and hit Enter:

slmgr -rearm

Step-3: You will be prompted to restart the computer. Once restarted, the trial period will once again be reset to 30 days. You can use the above command for up to 3 times by which you can extend the trial period to 120 days without activation.

Step-4: Now comes the actual trick by which you can extend the trial period for another 240 days. To do this, open the Registry Editor (type regedit in “Run” and hit Enter) and navigate to the following location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

Step-5: In the right-side pane, change value of SkipRearm to 1.

Step-6: Now, you should be able to use the slmgr -rearm command for another 8 times so that you can skip the activation process for another 240 days. So you will get 120 + 240 = 360 days of free Windows 7 usage.

120 days using “slmgr -rearm” command before registry edit


240 days using “slmgr -rearm” command after registry edit

=      360 Days

      Wow. YOU must have been sent from somewhere. I thought I won’t be able to use my laptop. I am getting the Black Screen of Death and spent sleepless nights to fix this to no avail.
      For the last time, I ask if I won’t be using my laptop forever just because my Windows is not genuine and lo! you solved my problem.
      First time for me to comment.

    But srikant,as u said, windows can run apporx for 1 year.. I have also cracked many paid softwares like this…HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform is an entry is registry which have a boolean value 1 or 0 …as changing from 0 to 1 extends windows 7 activation for more days….if we change value 0 to 1 whenever the value becomes 0 ..does it not make windows 7 for life time,, Or some other issue is also involved..?

    Now i want to format my system but i have lost the product key, the only thing that i have is product id. I want to reinstall the same copy on same machine. So plz help to find out that key either by manually in system registry or by the help of some software( window key finder).
    Is it possible to have the key from system registry as some where i have read that key is always there but in encrypted form??????

    It appears to only work if your trial period hasn’t “already” expired. Once the screen goes black and your identified as not genuine it appears that this fix will not work.

    November 30, 2012 at 12:15 PM

    I was having a problem at first but not any longer,this is awesome,thank you very much…..all those having a problem try the command again…….first enter space bar,type slmgr -rearm……it is working 100%…….i love this…..

    Hi, I tried the slmgr -rearm and I got the following message:

    “On a computer running Microsoft Window non-core edition, run ‘slui.exe 0x2a0xC004FE00’ to display the error text.

    Error: 0xC004FE00”

    I have been using the same version of Windows 7 since 2009, no problems.

    I can still use the PC, it’s just Microsoft Security Essentials that has been deactivated.

    Please, please help me, I am SO terrified of losing any information!!

    Hi, I tried to follow your steps, but when I typed slmgr -rearm, I got this message: slmgr is not recognized as an internal or external command, operable program or batch file.
    And then asked to type it again, which I did and this continued every time. So I cannot finish the steps.
    can you help me?

    I used slmgr -rearm for 3 times.. 120 days are over now.. I have also changed the value to 1 as you have said (it should be decimel or hexagecimal??) But it is not getting extended.. I read this post after 120 days expired.. Please help sir.. :(

  62. Keshav Poddar
    August 17, 2013 at 8:08 PM

    My 120 days of trail period are over. I changed the Skiprearm value to 1 as told by you. Then I used slmgr -rearm again, re started my lappy. Still it shows Windows is not genuine. I go back to regedit and find the value of Skiprearm to be 0 again.. Where is the problem?
    1. Is the Skip rearm value not getting saved? [whether it should be decimle or hexagecimal? ]

    2. Is it happening because I’m doing this post expiry of 120 days?

    Please help…

    In case of this error “slmgr is not recognised as an internal or external command” etc CHECK if your slmgr.vbs is actually named slmgr.vbs.removewat,

    open command prompt as mentioned
    type dir slmgr.*

    If you see in listing slmgr.vbs.removewat, then type ren slmgr.vbs.removewat slmgr.vbs

    Now, you should be able to use the slmgr -rearm command! :-) That was the problem in my case.
