Feb 05, 2015  I purchased windows 8 Pro having been using 8.1 preview for 3 months, installed ontop of w7. So given that 8.1 Pro final was available, I downloaded and installed successfully, using product key supplied with Win 8Pro. Activation was a joke - impossible whilst online, so contact CS who were less than useful - key interpreted as VLK.

On the black windows that appear, write : slmgr -rearm and push Enter.

Wait some moments and you`ll see the black screen dissapear and appear a box message that anounce you that your windows is activating for 30 days.

You`ll have to repeat this steps only in the final day of those 30, but before the hour that you make the first activation ! (you must be stil in the activated period to run again that commands).

In this way you can have your windows full option, for 4 month = 120days (first month - evaluating period + other 3 activations !).

After this period, you must change something in registry (to change a value from 0 to 1) and then you`ll have an other 8 month acivation, with the same method.

You can see the days remaining to the activation when you right-click on Computer, from the desktop, choose Properties and on the down page, you`ll see how many days you`ll stil have to the next opperation !

Now, to continue using your Windows (7 or 8 or 8.1) to the 360days, do this:

Programa Para Activar Windows 8

a) in the search box tape ,regedit', then go to the key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionSoftwareProtectionPlatform

b) in the right panel change ,SkipRearm' value from 0 to 1

c) now you`ll be able to use the command : ,slmgr -rearm' for an other 8 times.

With this method, you may use your Windows for one year, without buying a licence !!!

So, you`ll have: - 120 days before editing registry ;

- 240 days after editing registry
