It might not be such a good idea if the VM started as a physical machine and was P2V'd. Snapshots are your friend.

I don't believe so, Spin up a test VM, upgrade the processors to (2) or more it turns to Multi Proc when you look at Processors in Device Manager, then shutdown the VM remove a processor, it will still show a Multi processor in Device manager ( It should, I haven't tested) and Windows should load.

I'm curious, would decreasing the number of processors in a multi-processor vm cause a problem with Windows? I'm not talking about multi to uni processor changes, only multi to multi, like from 4 to 2 (or 8 to 4). I googled around a bit, but haven't found any info; most articles only discuss increasing cpus. If Windows is OK with a switch like that, how about ESX?
