Everything included in the 7z is needed to sync to a Windows 7 phone. Additionally, I will be including another hotfix soon to get rid of an error some have in some VMs.
EDIT: Scratch that, I just forgot to install WMP11b2 in the VM.
If you need any Zune language packs, let me know.
EDIT2: That WASN'T the problem. New pack pending as soon as I figure this out.
EDIT3: No new pack needed.
IF YOU GET AN ERROR SIMILAR TO THE FOLLOWING:
Zune has encountered a critical error and needs to close
Reisntall WMF! If you still have problems, use the media collection reset tool:

As well, the security updates for multiple versions of WMF are safe, and so is the WMDRM device update.
