Installing Windows 7 – Part 2
Scenario : You have finally installed Windows 7 but its only for a trial period of 30 days(You are not sure whether to purchase or not). And lo and behold….the 30 days are over but you are still not done evaluating.
Solution : Well….there is a way to fix this….and mind you it is not a hack, it is a system put in place by Microsoft to give you more time to evaluate it.
So how does it work ??
By default….Windows 7 has a trial period of 30 days(called Initial Grace Period) but once that is over you can “re-arm” for additional 30 more days of activation grace period, for up to 3 times, effectively allowing Windows 7 to run legally for 120 days without a legit or genuine product key to activate the system.
So How do you do it ??
1. First Login and check the activation status. To do so, open an elevated command prompt window as administrator, and run the following command:
slmgr /dlv (slmgr stands for software licensing manager )
The dialog box with the following details should appear:
License Status: Initial Grace Period
Time remaining: "As Applicable"
Remaining windows rearm count: "As Applicable"
2. In order to rearm the Windows 7 system for additional 30 days activation grace period, open an elevated command prompt window as administrator, and run the following command:
slmgr /rearm or slmgr -rearm
3. You can do this until your Remaining windows rearm count runs out. ( Interestingly this gives rise to a unlimited activation hack which we will discuss later 😉 )
Note : If you are not able to use this technique in spite of rearm count greater than 0, then do the foll. : Open 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) If not, set it to 0.
