Enable Shared PC with registry

We need to check if this script really enables Shared PC mode.
It works with registry, but there is also a way to work with Cim/WMI.
In the next few days I will check what is better.

Comparing Terminal Emulators

I have created this table with the assistance of ChatGPT and Bard.

My primary concern is to include all three connection options: SSH, RDP, and Web. However, none of the five completely free options can connect using all three options simultaneously.

If you require SSH and RDP connectivity, mRemote could be considered the best choice. For Web access, Hyper is a viable option as it offers both SSH and Web connectivity.

If you only need SSH access, SuperPutty is a viable choice, especially considering its password memory feature, which is not available in its closest competitor, MTPutty.

For a comprehensive set of access options, MobaXterm or Devolution RDM can be considered. Both provide SSH, RDP, and Web connectivity even in their free versions. However, they do have limitations on the number of sessions or connections allowed. MobaXterm permits up to 12 connections, while Devolution RDM allows up to 10.

RoyalTS also offers all three connection options, but Web access is only available in the paid version. Hence, if you prefer a free option, mRemote is comparable to RoyalTS in terms of features, and mRemote does not have any limitations on the number of connections.

In summary, the two winners among the free options are MobaXterm and Devolution RDM, considering their limitations on the number of connections.

Here are some additional details about each program:

• mRemote: mRemote is a free and open-source remote desktop connection manager that supports a wide range of protocols, including SSH, RDP, VNC, and Telnet. It has a simple interface and is easy to use.
• Hyper: Hyper is a free and open-source terminal emulator that supports a wide range of protocols, including SSH, RDP, and Websockets. It has a modern interface and supports a wider range of features than mRemote, such as tabs, split panes, and macros.
• SuperPutty: SuperPutty is a free and open-source SSH client that supports a wide range of features, such as saved sessions, password management, and tunneling. It is a good option if you only need SSH access.
• MobaXterm: MobaXterm is a freemium remote desktop connection manager that supports a wide range of protocols, including SSH, RDP, VNC, and Telnet. It has a powerful feature set and is a good option for users who need more than the basic features offered by mRemote or Hyper.
• Devolution RDM: Devolution RDM is a freemium remote desktop connection manager that supports a wide range of protocols, including SSH, RDP, VNC, and Telnet. It has a similar feature set to MobaXterm, but it is a bit less powerful.
• RoyalTS: RoyalTS is a paid remote desktop connection manager that supports a wide range of protocols, including SSH, RDP, VNC, and Telnet. It has a powerful feature set and is a good option for users who need more than the basic features offered by the free options.
