Microsoft Windows 11, like previous builds since first Windows 10, continues to install hidden mstsc-4b0a31aa-df6a-4307-9b47-d5cc50009643 files. During installation, the file is 4.7 GB in size, but it continues to grow up to 35 GB during the last check. To complete the picture, I will add to the review, after a couple of Windows updates, the file stopped updating itself and appeared in programs called "RemoteDesktop" with the signature of Microsoft, after choosing to delete it, a window popped up with a warning about a reboot, later I checked the file disappeared. It's hard to imagine that they stuffed a dozen GB there. Additionally, I decided to ask Microsoft technical support in the chat if this was really the case. The answer is as follows: "According to the check here, this particular code: mstsc-4b0a31aa-df6a-4307-9b47-d5cc50009643 is a Windows feature that is an important part of your infrastructure and operation. They're a built-in tool that offers enhanced security, and they're a key part of our engineering roadmap forward. In the future, you can expect even more features, such as the ability to better manage multiple connections". ???? What it collects, what makes it fatter, and where it connects is not yet known. In the registry:
You can see and uninstall (you can safely get rid of it) the file on your installation with the third party app UNINSTALL TOOL (hidden components)
false !!! 4.64gb are size of system32!! size increase because winsxs , if you need to reduce storage used use dism++ or cleanmgr+ and disable reserved storage !!!
@IXMas Is there any specific reason to "promote" a random closed-source uninstaller tool that miscalculates the installed size of several common Windows components, such as Remote Desktop Connection or Paint? I'm closing it here.
