Script put together by one of our devs - cycles through all datastores (or whichever ones are picked up by the name filter) and adds the parameters to any .vmx files it finds. Won't add them twice, and if they're currently set to true it'll switch them to false. Goes through the datastores rather than vCenter since many of our VMs aren't in vCenter.
Of course it should be easy enough for anyone who wants to customise this to change other parameters. The main bits to change to get it to work are the datastore name - remove this for it to apply to all datastores, and the url. It uses the web api.

As a note of warning - this can put a heavy load on your server's soap API, and is best run on a single datastore at a time, during low usage periods.
To second this warning, we just attempted to run this across a large selection of datastores and managed to kill off vpxd with a flood of requests. Best to keep it down to one datastore at a time, or build a delay in before each request runs.
