unable to uninstall updates in windows 7

[AWS]

Version of Windows: 7 Home Premium, 64-bit OS (I don't see any service pack # when I look at Windows Edition under Computer--system properties.  If there is somewhere else I should look, let me know)

the problems (performance so slow I can't do anything) started after installing downloaded updates

     -update for MS OneNote 2010 (KB2553290)

     -update for MS Office 2010 (KB2553310)

     -update for MS Office 2010 (KB2553092)

     -update for MS Office 2010 (KB2553270)

 

when the computer starts in normal mode, it is EXTREMELY slow and I get various pop up messages like 'problem starting rundll'

 

I have tried to do a system restore, but there is no system restore point.  I have read that I can create a system restore point now, but I don't see how that will help me since I need one from a time before the updates were installed.  Is there some way

I can find such a system restore point that I don't see when I choose system restore?

 

I have tried to uninstall the updates but see 'an unknown error occurred.  the update could not be uninstalled.'  Perhaps that is because I am in safe mode, but I can't uninstall in normal mode because I can't operate the computer in normal mode.

 

I also tried using a microsoft support fix it tool to diagnose problems with windows updates.  the result is

Issues found:  Repair Windows Update components                           Fix status: not fixed.

 

I did have a similar issue with a windows security update in the past.  After installing that update (I don't have a record of the name/number of that update), I got countless messages about not able to run xxxx.  That time, I went back one day with system

restore.

 

My anti-virus program is Norton AntiVirus.

 

Please tell me if you have any suggestions to either help me do a system restore or how to uninstall the windows updates.  I would love to get back to using the computer in normal mode.  Thank you very much!
