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.

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.

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.
