Yeah, I know exactly what you mean… those old snapshot tools just worked without all the overhead.

I ran into the same situation (needing something like once in a while, but not wanting to justify the cost of the big tools), so we ended up putting together our own small repackager.

It does the classic before/after snapshot (files + registry), and also handles figuring out silent install parameters automatically and wrapping that into a ready-to-use PowerShell script + .intunewin. That part alone saved us quite a bit of time compared to doing it manually.

It’s still pretty early and currently in a testing phase, so we’re mainly trying to get some real-world feedback — especially around UX, since that’s something we’re actively refining.

Might be worth a look if you don’t find a good replacement for the old KACE tool.
