Windows (let's say Windows 10) comes with Remote Desktop Connection. If I buy two identical laptop computers and connect them with an ethernet cable, what can't be done over this connection (but can be done directly)?
For example, by default, it seems that a User Account Control prompt can't be answered. But, Microsoft does allow a registry change to fix this, so let me reword my problem to consider two identical laptop computers with their registries modified "for maximum operation". I'm trying to find the true limitation of Remote Desktop.
For a second example, I would think that there might be a problem if I use Remote Desktop to Remote Desktop back to my original computer...but I've never tried this. I'm actually wondering if there are examples without resorting to this recursive limit.
