How to Use Windows 7 without Activation?

1. Go to “Start Menu -> All Programs -> Accessories”. Right click on “Command Prompt” and select “Run as Administrator“.

2. Now type the following command and hit enter “slmgr –rearm” without cotes.

(You will be prompted to restart the computer. Once restarted the trial period will be once again 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.)

3. Now comes the actual trick by which you can extend the trial period for another 240 days. Open Registry Editor (type regedit in “Run” and hit Enter) and navigate to the following location “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform”

4. In right-side pane, change value of SkipRearm to "1". Now you will be able to use the slmgr -rearm command for another 8 times so that you can skip activation process for another 240 days!
