Windows 7 Service Pack 1 x64 Update Error 80070002

[AphexCCFC]

Hello. I have noticed that there are 309 errors in my CBS log but I don't know how to fix them. I've been trying for around 6 months to install service pack 1 but no matter what method I try it fails showing the 80070002 error.
Here is my CBS log:

You have a considerable amount of corruption present - I think your best bet is going to be to do a repair install of WIndows.

I would have considered that method but unfortunately I don't have the Windows 7 disc and it's too expensive for me financially at the moment :/

If you look, you can download the ISO file and create your own disk - for free.
