RustDesk

RustDesk has a perfectly optimized system for allowing any user, regardless of their tech knowledge, to easily establish remote connections, change user permission levels when establishing a new connection, and transfer files.

RustDesk is a small in size file that does not need to be installed or configured in advance. All you must do is download the file and start it by double-clicking the executable. The tool is semi-portable, meaning it does not require installation, but leaves certain files in your system (in AppData, some configuration TOML files and logs about previously established remote connections). As such, logs and detailed information about previous sessions can easily be found in your system if needed.

After opening the tool, you will notice a left-sided panel that displays your device's credentials for remote accessing — the ID and the password. The ID is unique, but the password can be changed by clicking the random generator that automatically creates a new identification code. To establish a new remote connection, you must have RustDesk on another PC and insert there the unique ID and password of the machine you wish to access.

Also, it is important to add that all sessions are registered and, as a virtual machine's panel that shows you all the sessions of boxes you created, RustDesk will create different instances for all the computers you accessed, referencing them by their operating system and unique identification code.

Currently, RustDesk works on a single dev-hosted server. If you wish, the service's functionality can be extended. The developer offers you the needed technical assistance, via guided steps, on how to set up a server. Via client-side configuration, with payment in advance, you can configure your own cloud, using your unique server-side ID. For more details, check this guide.

To summarize, this app is super powerful, it has a lot of nice features and allows for a parallel view of your system files for easy data transfers (from the host's system and the receiver's machine).

You can interact with a lightweight application that is intuitive and simple. Also, while remotely connected to another device, you can easily adjust the image quality, change permission levels, chat with the person who's accessing your PC.
