I have subsequently obtained and filed the full diagnostic report and await a reply
A very disconcerting remark at the start of the report is:
Validation status : Invalid license
Validation code : 50
I bought my laptop from Dell direct with Vista pre loaded and it worked fine for some years so why has the license now become INVALID? Was I supposed to buy Win 7 after a certain period of using VISTA--no one told me so !!
MSFT please explain or refund me the cost of Vista to fund the purchase of Windows 7
Thank you
