Mouse Support during OSD after WinPE stage
During OSD in Windows 10, the Mouse gets suppressed and you can't see it after the "Setup Windows & ConfigMgr Step" until the end of the TS. Many of us have cheated by adding a registry value in the offline OS
MS has even blogged about it:
My Request is... Build this into the Setup Windows & ConfigMgr step.
In that step, you're already mounting the offline registry, just add that value while you're in there. Perhaps make it controlled via a checkbox on the step or variable.
I see on your page you recommend undoing the change at the end of the TS, but I've never seen this causing an issue by leaving it. Perhaps you could resolve this by adding it into one of your scheduled tasks.
During Offline, you set that key and one additional key that says this key was changed by CM during OSD
CM Scheduled Task POST OSD, checks that key to see if set, then checks to see if it was set because of the TS, it then "fixes" the key and removes the "Set by CM" Flag.
