Hi Nikost, and welcome to Seven Forums.
On the first tutorial, right click on the shortcut and click on Properties. Under the General tab, click on the
Unblock button if there. This may be the cause of UAC popping up on you for it. If it's not there, then it is already unblocked.
If you
disable hibernation, then the other one should work as well.
Hope this helps,
Shawn
