At last I bought Windows 7 ultimate for $320 ($2,499), from history here I bought Vista nearly 3 years ago. The rearm trick didn't work and I have no other alternatives of OS for work. My MacBook Pro just can't connect to network resources running obsolete versions of windows server here.
To do that first of all I need elevated privilege as administrator, do that from below
then I ran this slmgr - rearm, I then got a successful prompt and rebooted it.
Windows is still shutting itself down every 2 hours?
My diagnosis of my own leg pain problem appears to be correct. Since then I bought myself a new pair of shoes and new Nike+ sensor after a run on 31 Jan.
I had two 5k runs recently with pace gradually improved from 6:58 to 6:44 per km. I will from now on focus on 5k run with a target to do it in 30 minutes.
