Windows 7 Pro Services to disable for Forensics station?

I finished setting up a dedicated forensics workstation that is running Windows 7 Pro on it. I wanted to see if anyone had recommendations for services to disable in order to speed up the indexing of data?

I connected the workstation to the internet updated everything, then installed AV, updated it, scanned it completely. Then I unplugged from the internet, removed AV. Now, I want to see what I can turn off from a Windows Services side.

Any help would be greatly appreciated.
