We had a consultant come in and do the BIOS switching magic, so not my time spent. ☺
SP1 also has some things that will help the required TS issues, but it doesn’t account for massive amounts of machines being added to a collection with deployments already on it.

I've been wanting to write a system that did the following: Query 1: Whenever a TS deployment is made, run a PS script that checks the number of clients in the collection. If > a certain %, it changes the deadline date of the deployment. Also, it creates a status message query for the collection it's deployed to that runs a PS script whenever the collection properties are changed (ie, rule added). That script waits until the collection refresh is complete and then checks the number of clients. If > a certain %, it changes the deadline date of the deployment. It could also automatically remove any include collection rules to avoid the I added to x collection which includes to y collection which adds the computer to the imaging collection. Query 2: Whenever a collection is removed it checks if any status filter rules are associated with the collection and, if there are, removes them. Query 3: Whenever a TS deployment is removed it removes status filter rules associated with it. I'd prefer something like this was built into ConfigMgr, but status filter rules could probably do it.

These are risks for you to weigh and there are ways of mitigating them but there are at least three very well known cases of a TS being deployed as required to all systems in an environment and causing major havoc as well as being an RGE.

We don’t recommend even trying – just keep the system running legacy BIOS emulation until it’s replaced (or until you “reclaim” the system for redeployment). If you just want to automate the switchover (and destroy the contents of the drive later), it’s a little easier, but still vendor-specific (to modify firmware settings). You would only want to consider this for Windows 8 logo-certified devices (those running UEFI 2.3.1 or higher), since previous UEFI versions were way too flaky. I would also start thinking about this as a point-forward change: Stop deploying Windows 7 systems using legacy BIOS emulation if you are planning to upgrade or refresh them to Windows 10 sometime within the machine’s lifetime.

Switching the BIOS to UEFI with a command line isn’t the problem, but doing this as part of OSD might be. Refresh using hardlinks can’t work, but anyone tried switching to UEFI during OSD for baremetal? (That of course would lead to a mix of legacy and UEFI installations) Assuming the computer is currently configured to use Legacy bios mode, that seems like a chicken/egg problem. -Roland The information transmitted is intended only for the person or entity to which it is addressed and may contain CONFIDENTIAL material.
