How to clean that hyper-v mess?

I just want to delete all of them.

And yes, right click -> uninstall does nothing :(

I tried deleting the regedit entries and got a permission denied.

I tried to set permissions to the entries and got a access is denied:

C:\> subinacl.exe /subkeyreg HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\ROOT\VMS_VSMP\0002 /grant=administrators=F

The title pretty much says it all, is there any advantage to giving a VM 2048MB of memory instead of rounding to base-10 and doing 2000MB?

It seems like a simple thing to find the answer too. But, I can't seem to find it in the Hyper-V doc. I'm sure it's there somewhere.

Simple question, when I am in Hyper-V manager there are two options that seem similar but I am sure they are different. "Turn Off..." and "Shut Down..." What do they each do?

My gut tells me that "Turn Off..." is like pulling the plug on a physical machine where as "Shut Down..." sends a shut down message to the guest. Is that correct?

In both cases is the VM no longer running and using memory and CPU resources on the host.

With the new Xeon CPUs supporting Hyper-threading, what is the current wisdom with regard to using it (or not) on a Hyper-V host machine?

I was originally under the impression that turning it on in a virtual host environment could be detrimental as the 'extra' CPUs were not true cores. However I've also read (unconfirmed) comments along the lines of MS doing some hard work to get Hyper-V running well in a Hyper-threading environment.

Does anyone have any solid information or experience in this regard? Cheers!

Does Windows 7 support running Hyper-V Manager?
