Hi Jeff,
Good to hear from you -  looking for lock-down things to do it seems  .
MS Autocollage is not supposed to work for W10 but it does
There is a free up t date version here called Coolage!:
https://www.microsoft.com/en-gb/p/coollage/9wzdncrcs1h5?activetab=pivot:overviewtab

I've had a very quick play, it possibly has more features that the old version but I've only just installed it.
Click "GET" on the web page, It should then automatically download and install. It's free so not need to go via checkout. I have an MS account so not sure if that's essential.

I'll send you a private message which may help with the old version.
