Windows Update and other Windows programs don't work
I did a clean installation of Windows 7 a few days ago. I used the HP repair program to install it since Windows 7 was installed when I purchased the system. I don't have installation disks. Update: I do have Win installation disks but they're ISO disks I used during a Repair Installation, see below. I'm running Windows 7 Home Edition.
Soon after the installation I noticed that I couldn't install Microsoft Security Essentials or run the Windows Troubleshooter / MS Fix-it Center or Windows Update. All other programs that I installed work okay.
I ran Norton Security Scan and Norton Security and no viruses were reported. Then I ran sfc / scannow a few times. Each time, corrupt files were reported. I reviewed the CBS log files and could find no specific references to corrupt files. No corrupt files were reported as being repaired.
The system passed all diagnostic tests run at bootup: startup, PCI devices, hard disk and memory.
What are my valid options? I'm inclined to think I should do a repair install, although on one website a couple of Microsoft certified advisers recommended a clean installation to address the problem of MS programs not running. Should I upgrade to Service Pack 1 first? Do I need to do a clean boot first? The last time I did a repair install, a couple of years ago, it worked well.
