How to Rearm / Activate Windows 7 for 120 days


Windows 7 rearm is just like using Windows 7 trial for 30 days.  This rearm can be done  four times maximum. Today we will talk about how to do that.

Most of you know that Windows 7 RTM is out now though not officially. For those of you who are over enthusiasts and cant wait to test windows 7, must have downloaded Windows 7 RTM from somewhere either from torrents or some warez networks.

As many of you have noticed, you can’t use release candidate RC or beta keys to activate Windows 7. You still need to wait till Windows 7 is officially available to public. Till that time you can use it as evaluation copy but just for 30 days.

There is a legal way to activate it for 120 days till public release. It is not a hack, it is a system put in place by Microsoft to give you more time to evaluate it.

1. Open the Start Menu.

2. In the Start Menu search box, type Regedit and press Enter.

3. In the registryEditor, go to:
HKEY_LOCAL_MACHINE >> SOFTWARE >> Microsoft>> Windows NT\CurrentVersion\SoftwareProtectionPlatform . In the right pane, see if SkipRearm is set to 0 (number 0)

Windows 7 Skip Rearm5. If it is not set to 0 – Right click on SkipRearm and click on Modify. Type 0 and click on OK. (See screenshot below).If it is set to 0 – Skip this and go to step 6.

6. Open an elevated command prompt (it will be elevated if you are Admin, or if not just run it as Admin)
7. In the elevated command prompt, type slmgr -rearm and press Enter. (See screenshot below)

    • You need a genuine Windows 7 key to activate it.This rearm can extend the evaluation period to 120 days only. RTM is out already but will be available to public later on.

      • Alright thanks. Btw, any info about “Windows 7 Ultimate Cracked and Activated Permanently with OEM SLP Master Product Key (with SLIC 2.1)”?

  1. most of your steps with the registry are not needed..

    Open a elevated command prompt (it will be elevated if you are Admin, or if not just run it as Admin)

    In the elevated command prompt, type slmgr -rearm and press Enter…

    not sure what all the unecessary regedit stuff is about..Ive been re-arming for ages on many versions and its never been necessary. just do the command line stuff

    • Yes i know many of the Registry steps are not needed for most of guys but many guys get stuck with some error if they don’t know what they are doing. Its just for help of those guys who get stuck with some errors.
      Otherwise for tech savy guys, running the rearm script/command is just typing a simple command.
      And hence the need for this article wont have risen as its just a simple command.

  2. Is second time it works for me.. it worked for my brother giving 30 days.. I didnt count my first activation,s days… but Thank You so much 😀

  3. i have a problem while doing command prompt part ” access is denied and it requires elevated privileges..

  4. I could not rearm windows 7. Following appears on the screen whenever i press enter after typing slmgr -rearm on command prompt
    Error:0xC004F025 Access denied: the requested action requires elevated privileges

  5. What happens after 120 days, will i not be able to use the same method to re-arm Win7 again.That would be fun.

  6. Dear Avinash,
    I have installed W8 , and it was written in license that it is activated and rearm time is 1000 … can you please explain what is that?

    • In Windows 8, rearm can be done much more times compared to Windows 7. We are still not sure about the maximum count though.
