Error Code- 800700C1, having problems with windows update

Original Title: having problems with windows update

Hi not too familiar with how this works but I'm having some issues with Windows Update.

Since about February my updates went smooth and everything, but after that even when I'm attempting to install multiple updates it will show less than what I am trying to update and come up with the error 800700C1. It mainly consists of Updates for Windows 7

I'm running Windows 7 Ultimate SP1 and im having issues installing the following:
KB2647516
KB2633873
KB2621440
KB2641653
KB2654428
KB2665364
KB2667402
KB2639308
KB2640148
KB2660075
KB971033
KB2647518
KB2607576 (one of the optional updates)

Got this computer from a used computer guy and didn't get a restore disc, prefer to leave a fresh install as a last resort if possible, but tried just about everything I can think of (Windows Fix-it and some other things that were supposed to help)


Edit: Alright thanks for the help, tried the first two ideas but no luck, going to try the third in a bit.

Note: Make sure you enable the antivirus software, other security programs and firewall after the test.
 
Warning:
Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
 
Try to install the updates.
 
Method 3:

Perform a clean boot of the computer.
 
Clean boot-   It’s a process wherein you can start Windows 7 by using a minimal set of drivers and startup programs.  A clean boot helps eliminate software conflicts.

Try installing the updates in clean boot mode.
