can't extend windows 7 trial period past 120 days

I'm reading from a article on this site named "how-to-rearm-and-extend-free-usage-activation-grace-period-of-windows-7-to-120-days" and from one of the comments posted a user says to

"1. Type in the “Search Box” > regedit and then go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\ SL or instead “SL”, search for “SoftwareProtectionPlatform”;
2. In the right panel change “SkipRearm” value to “1″;
3. From now on will be able to use “slmgr -rearm” for another 8(eight) times. So you’ll have a total of 360 days for using Windows 7 without activating it."

I used the slmgr.vbs -rearm command after i edited the registry setting and it asked me to reboot after it finished. windows is still saying i have 2 days left to activate.

i looked in the registry again and the SkipRearm value was back to "0"

how do I get the registry to save the new value I put? I just exited the registry after i clicked modify and changed the value to 1. not sure if there's a specific way of saving the changes.

 

I used the IR4 tool and it worked, thanks!

I can't use the daz loader, i've tried before but it always crashes my system no matter what mode i try installing it in.
