Hello
In your Diagnostic Report it shows the error code "Online Validation Code: 0x80070426". This means that the Software Licensing Service has stopped. Vista uses this service to check itself and confirm it is Genuine. When the servise is stopped, Vista is unable to confirm it's own Genuine status and assumes something (or someone) has tampered the Software Licensing Service and flages itself as Non-Genuine.
If you have acces to the Start button:
1) Click the Start button
2) Type: cmd in the Start Search field
3) At the top the Start window, you will see cmd.exe
4) Right Click cmd.exe and select Run as Administrator
5) Type: net start slsvc
If you do not have access to the Start button:
1) Click the option that opens an Internet Browser
2) A Browser will open, type: %windir%\system32 into the address field
3) Find the file cmd.exe
4) Right Click on the cmd.exe and select Run as Administrator
5) Type: net start slsvc
If the above steps did not start the Service, please see below:
The "net start slsvc" command is the manual command to Force Start the file slsvc.exe (which is the Software Licensing Service). I don't know of any other way to start the service (it's like clicking on the Internet Explorer icon and the browser not launching). The only reasons (that I know of) that "net start slsvc" wouldn't start the Service is that:
a) Some 3rd party program is preventing/suppressing the service when the service attempts to launch.
b) There is something wrong with the slsvc.exe file (this is not the issue, in this case, since the Diagnostic Report did not shown that the slsvc.exe file had been modified or become corrupt).
c) Something is wrong in some core area of Vista, in such a way, that the "net start slsvc" isn't being processed correctly.
Since a) and c) are outside of my area of knowledge and b) has been ruled out, I really couldn't be more help. So in this event, I would suggest going to http://support.microsoft.com for additional support options.
