Let Windows 7 use 360-day free method to get

. This activation is 啥 I want to say "official" (with quotes), because this is within the scope of Microsoft's permission.

now activated the methods in addition to purchase genuine serial number, the network also spread a lot of ways, but those free methods first violation of Microsoft's use agreement. In addition, many methods use the replacement method, or brush the BIOS. The result is computer damage or system instability, which is not worth the candle. Let me talk about my method. This method has been personally tested by the author. This method works for any win7 version.

1, after the first installation, a 30-day period.



2, when the 30-day trial period is about to end, with the rearm command to restart the computer after the remaining time and return to 30 days. The official Microsoft document states that the order can only be used three times, which means that it can be used for a total of 120 days for free.

The method is as follows: Open the attachment - command prompt. (Note that you want to run using the right-click admin mode). Enter the command "slmgr.vbs/rearm" on the command line to extend the usage period by 30 days.


After rebooting the system, it will be restored to 30 days.

3, the above process three times, a total of 120 days, will not be used again thereafter. To proceed to the next step, modify a key in the registry, you can reuse the above command, please open the Registry Editor, and then navigate to "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSoftwareProtectionPlatform".


As shown in Figure 3, find "SkipRearm" in the right pane, change its key value to "1", and then use the "slmgr.vbs /rearm" command again. This key value can be modified a total of 8 times, which means that we can repeat the command of "slmgr.vbs/rearm" 8 times.

so the time can be used for free as follows: initial installation of 30 days, the first time the slmgr plus three 90 days, and then modify the registry 8 times 240 days.

My God, Win7 can be used for 360 days "free"!

Some people say, how to do a year later? I don't believe that you will not reinstall the system once in a year.
