Windows 7 Pro - Validation Issue

I bought a computer in March/April 2013 with Windows 7 Home installed as OEM.  I have since upgraded to Windows 7 Pro, but I still cannot get past the online validation test, although I pass the Genuine Windows with 0x0.

Lately, I am getting too many errors in Windows reliability applet.  Over the past months I have spent more time futzing with Windows system than on my own work, most of which done with win-32 applications.  Does anyone else have these problems?

maybe it is time to do a fresh install of the windows 7 pro, of course you want to backup your data first. Note a fresh reinstall will wipe out any applications you have installed. Sometimes instead of wasting more time troubleshooting it makes more sense just to backup your data then to a fresh install.

I'd do an overinstall first..

Question: how did you do the upgrade? did you use windows anytime upgrade?

just to add to my previous comment, you should run that command in an elevated command prompt

it is a very simple procedure and shouldn't take too long, so i would try that before re-installing anything.

Try the command line activation using your upgrade key.

You can use this tool to help diagnose why WGA isn't happy with your product activation

It will create a text file log you can upload for analysis.  This will contain fragments of your activation key but not enough for it to be copied.
if you have the original  window key use it  otherwise need new window pro need key you can buy from Microsoft .

I have tried the script and I see a brief appearance the Command Prompt window, and no error messages.  Thanks.  I'll see if that offers any improvements.

I have gone that route a couple of times earlier this spring.  It's a painful time-consuming ordeal, but I will try it as a last resort.  Trouble is the software has become so complex, I find myself spending too much time worrying about the health of the system.  I'd give my kingdom for Win 3.1.
