Hello Mandar Aryamane
Welcome to Microsoft Community.
Assuming that you are currently controlling ten other physical computers from one physical computer, this case is essentially a multi-computer setup, where multiple computers are controlled by a single set of input devices. Here are some suggestions that might do this:
Disclaimer: The following suggestions may involve some hardware introduction, but Microsoft does not manufacture these Hardwares, and you may need to search for companies that manufacture these Hardwares.
- KVM Switch: A KVM (Keyboard, Video, Mouse) switch allows you to connect multiple computers to a single set of input devices. With a KVM switch, you can switch between the different computers by pressing a button on the switch itself or by using a hotkey on the keyboard. However, this solution does not allow simultaneous control of all computers, which seems to be a requirement for your use case.
- Software-based solutions: There are several software-based solutions that allow you to control multiple computers from a single keyboard and mouse, you can move your mouse from one screen to another seamlessly, and your keyboard will automatically switch to control the computer that the mouse is currently on.
- Hardware-based solutions: There are hardware-based solutions that can help you achieve simultaneous control of multiple computers. One such solution is called the multi-Point services. With this method, you can control multiple computers using multiple keyboards and mice, all at the same time. For more details of this services, you can click the following article
