Vista: Unsuccessful Service Pack 2 install (Error 80070426)

original title: the Service Pack installation failure

I have a HP Pavilion 061 and Vista Home Premium 32-bit running. The following has occurred:

1. Windows has detected an update, service pack 2. It came out like two years ago, so I don't know why my system just inform me of the update. I did the update. After installation, I couldn't start my computer to run Windows. I could access the screens before starting Windows. I tried a variety of options, but could not do anything for work. SafeMode would note boot Windows. System Restore does not seem to work and start with an earlier version of Windows does not work, even though I'm not a very competent with these options.
2. I used the 'Windows Vista Home Premium Express Upgrade' original CD. It reinstalled Vista without any service packs or updates.
3 Windows started, but I lost all my old files and programs.
4. I tried to install Service Pack 1, but it would not be installed successfully. I ran the software to Microsoft for Service Pack 1 upgrade and tried the upgrade. It did not work.
5. my Control Panel does not open.
I need help:
a. install SP1 so I can run the Office 2010 software
b. to restore files lost, if possible
c. open my control panel
In my view, that a virus may have caused this. I ran Avast, but nothing is found.

I run Avast, the free version. He will do a 'quick scan' and didn't find any viruses. When I do the "full system scan", it crashes and the computer shuts down.

Or, you see the effects of an infection (perhaps because the computer Vista was online without being fully patched) or the effects of not running the Norton Removal Tool when you should have done.

In any case...

If (and only if) you can use the Vista Upgrade disk to do an clean install of Vista (after formatting the HARD drive!), see the poster in this thread and follow the instructions of (my) WHOLE (to the letter and in order! ) to return Vista to a safe & functional State: http://answers.microsoft.com/thread/c44429fb-3f7c-4646-8529-5a97bb3cd0eb

If you need additional help with the clean install of Vista, please start a new thread in this forum: http://answers.microsoft.com/en-us/windows/forum/windows_vista-system

Otherwise, you will need to format the HARD disk and then perform a new installation of Windows XP. Once you get fully-patched WinXP again, you would be able to upgrade to Vista again (but why anyone in their right mind does not want to do, is beyond me). Follow the instructions in this post of mine in another forum (to the letter and in order! ) to return Windows XP to a safe & functional State: http://aumha.net/viewtopic.php?f=62&t=44636

If you need additional help with the clean install of Windows XP, please start a new thread in this forum: http://answers.microsoft.com/en-us/windows/forum/windows_xp-system

Wish I had better news for you.  Good luck!
