I'm not sure if this is the right forum for this problem, but I will give it a try.
I am running Windows 7/64bit. About three weeks ago I removed my internet security suite in favor of using Windows firewall and MSE. I made sure that the internet security suite was completely removed from my computer.
I went to Control Panel>System and Security>Windows Firewall. On the right side of the page, it said that Windows Firewall was not using the recommended settings. There is a Use Recommended Settings button to the right of that. Nothing else was there. On the left side of the page was a list which included Turn Windows Firewall on or off.
When I clicked on the Use Recommended Settings button, I got an error message......
"Windows Firewall can't change some or your settings". Error code 0x8007042c.
I then clicked on the Turn Windows Firewall on or off link. Nothing happened.
I gave up there and decided to try installing MSE v2. Another error message with an different error code. Error code 0x80070643.
I did a Google search, found some things that were recommended, but nothing seems to work. I was thinking of doing a Win 7 repair, but not sure if I should try that. This HP Pavilion didn't come with a Win 7 CD. It came with four restoration disks. I do have a Win 7 CD, but not sure I want to use it on this computer. Any ideas what is wrong, or what I should do?
