I just used Acronis True Image WD Edition to clone my 1TB WD SATA drive to a 2TB Seagate SATA Drive to upgrade the boot drive in my HP PC. The cloning process went well and was without errors, and the computer boots fine from the new drive. All settings are correct, etc. The problem is that I can no longer get Windows Updates, download updates to Security Essentials, or upload troubleshooting info to MS. I can access the internet, browse sites, download files, get e-mail, etc. I did have to reactivate Office 2010 when I booted from the new drive, and that went fine.
Windows Update gives me an error message that the update service is not running and I should restart the computer. However, according to services.msc, the update service is running. I tried stopping and restarting the service but it didn't change anything. It was suggested that this hardware change might have caused Windows to deactivate, but it still shows as activated. Nonetheless, I reactivated it (successfully) but there was no change.
The UAC message I get before I run any MS system program (like mmc) shows the publisher as "Unknown". My user account (the only one on the machine) has Administrator privileges, but in order to run certain system programs from the command prompt I have to invoke cmd.exe by selecting "Run as Administrator" or else I'll get the message that I must have Administrator privileges to run the particular system program.
When I reinstalled the original 1TB drive, everything worked fine.
Frankly I'm stumped and would appreciate any ideas as to what may have happened and how to fix it.
