Windows 7: Svchost.exe High memory usage at startup

Well, I am not an expert by any means, but I believe MS finally fixed the issue caused by 2 GiB memory machines in a recent update (Can't remember where I read about it at this point in time). However, from what I understood, the issue (Which seemed to come out with a windows update 'update', in spring-ish of this year) mostly only affected machines with less than 4 GiB of RAM, which is why I simply decided to upgrade my RAM to 4 GiB to avoid the issue (For only $8.99 on ebay, it was an easy and painless fix).
I originally used that code above as a temporary fix. Once I did some research in my free time, and felt confident more RAM would fix the issue, as it seemed MS was not doing anything quickly to address it, I ordered the memory to alleviate the problem. It seems however that very recently MS did finally release a KB fix for the issue, but the increase in RAM never hurts.
My only issue was is it seemed that code left a residual effect of changing the WSCSVC from it's default setting to manual even after I removed it (or rather, it probably changed it when run originally, and removing it did not change it back). I did not change the service(s) (well... the code I copied and ran did, but I did not knowingly stop the service(s)).
Since the computer now has all action center and windows update services running normally upon reboot again and my memory usage is holding @ ~25% (of 4 GiB), I think my problem is resolved and I will skip the long winded difficult fix I do not seem to need!
Thanks!

I will add that this fixed my issue with svchost.exe constantly taking 50% of the cpu, sop basically when i ran Chrome and/or Firefox and a couple of other apps, I'd be up around the 95 - 100% CPU usage and basically this was making the system non-responsive and very sluggish.

Changing the "Windows Update" service settings to 'dsiabled' it brought my system back to life and the CPU was functioning normally, bouncing around but usually sitting at under 10%.

As for the updates, I will do them manually once a week.
