VNC is the kind of the baseline remote desktop that works on pretty much any operating system. You can start there & then decide if you need specific features that the others have.
You didn't mention your own OS but it too probably already has support for its own remote desktop solution.
Windows has its default Remote Desktop Connection that uses RDP (Remote Desktop Protocol), once enabled it will listen on port 3389. It is pretty solid and has a few features beyond VNC. Just be careful, you probably don't want to open that port onto the internet since every port scanner is scanning that port & looking for unpatched Windows vulnerabilities or insecure user/password logins.
I use RDP myself for my Windows system but I need to SSH into my network before using it, so it's really RDP over SSH. If you're not going to go through all that at the very least change the port to something else so it doesn't get port scanned to death.
.. TBH if you're not too sure about how to secure this stuff maybe Chrome Remote Desktop is the best option, at least it's secured behind your own Google account (hopefully that itself is secure and you have 2FA enabled).
RDP is kind of limited because it's a virtual session. It's useful if you only need to do stuff while you're actively connected but you can't, for example, remote in and start an app or process going and then disconnect and have that app continue. When you d/c your profile is essentially logged out. Your activity also can't be viewed by a user on the remote system, if you needed to collaborate or assist somehow.
UltraVNC has worked ok for me for windows systems. It has some of that open-source clunk to the UI, but is pretty straight forward and does what I need.
It’s useful if you only need to do stuff while you’re actively connected but you can’t, for example, remote in and start an app or process going and then disconnect and have that app continue.
Sure you can, I do this all the time on the work RDP server. Maybe you need to tweak your group policy so it doesn't kick you out right away.
When you d/c your profile is essentially logged out.
Nope, depends on what group policy you configured. If you've never configured that before as a starter launch gpedit.msc (with admin privileges) and head to Administrative Templates / Windows Components / Remote Desktop Services / Remote Desktop Session Host / Session Time Limits. The other settings in there are also useful for other things you may want to configure.
Your activity also can’t be viewed by a user on the remote system, if you needed to collaborate or assist somehow.
Yes this is true, the only way to do that is to have admin privileges on the host and then take over that user session. But of course that's not collaboration, that's just you taking a user's current session without them being able to see what you're doing.
On Windows the official way to do that is via Quick Assist (on Windows 10, not sure if it got renamed on Windows 11), it's sort of a shared RDP session where both the user and the remote user can share the same session. I've never needed to use it myself - with the work system users are pretty content with just having me "fix" whatever they needed without them watching, they usually don't care how to fix the problem themselves LOL.
What? This just isn't true? I RDP into work all time and it picks up my user session with all open apps from the last time I was physically at the machine. Then next time I'm at the machine, it picks up the session from last time I remoted in. In other words, as long as you always use the same account, it's always the same session.
Your activity also can't be viewed by a user on the remote system
You are right this, but this is actually a benefit in my opinion. The last thing I want is for someone to turn on my monitor and see everything I'm doing. I like that it's a private session of sorts.
Also RDP is better at adapting resolutions (I want my session to use my local monitors' resolution, not the remote one) and forwarding system key shortcuts than any other remote solution I've used.
I switched over to anydesk when TeamViewer started enshitifying itself, haven't looked back it works great on all my devices, even my phone (as in I can control my PC from my phone I use it a ton)
Setup is super easy, just make sure to set up proper passwords for it, specially if you use public wifi
Maybe the Windows clients are paid now? But I use it currently for free on many Linux boxes. I haven't logged into one of the Windows boxes like my mother's office computer to fix something in a while.
I have had nothing but great experience from Parsec. It's gaming intended, but works perfectly for simple remote desktop use as well. Very low latency. Can start when windows boots, so you can even sign in remotely if you need to restart. Free
