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.

  • I've tried playing Warframe over Remote Desktop before. The game refused to launch, saying it wasn't supported over Remote Desktop or something like that. – Hydraxan14 Dec 20 '16 at 22:50

    "For example, by default, it seems that a User Account Control prompt can't be answered." I do this all the time in my lab. Why exactly are you doing to RD RD back to the original PC? – Ramhound Dec 20 '16 at 23:21

    Just as you noted from the question, the answers could get into recursion and permutations of recursiveness. If you have a specific question we would probably find a specific answer, but as asked this question is too broad to be satisfactorily answered. – music2myear Dec 21 '16 at 0:09

What can't be done...

I imagine there are others, but this for starters.

Accessing the remote graphics or sound setup, as they're not really running. Instead you are using substitutes

...which is why you can't play games.

  • And which is also why you can't install or update graphics drivers remotely. – Nassbirne Dec 21 '16 at 8:36
  • Actually you can install updates, just not via the Control Panel. if you fetch directly from NVidia etc, then they install just fine. – Tetsujin Dec 21 '16 at 9:09
  • Oh, that hadn't occurred to me. Microsoft could have done this differently, but I can see their technical reasons (instead of security reasons, thanks!) to limit things. If I needed to adjust the true graphics and sound (I would really prefer to just get a remote clone, so the audio, for example, would get played on both computers), I now wonder if there is a better alternative to RD. My motivation, since people are questioning it, is just to be able to help my grandma out remotely. – bobuhito Dec 21 '16 at 13:19
