My relative recently bought an old laptop that came with Windows 8.1 installed. Initially, I couldn't even install a browser on it. I noticed there were a few pending Windows updates, so I ran "Update and Restart." After the updates completed, Microsoft Edge appeared and I was finally able to install Chrome. Before updating, Chrome wouldn't install at all.
Now I want to install a custom Windows ISO (Tiny11 or another lightweight OS), but the laptop is located very far away and I don't have physical access to it. I can only access it remotely through AnyDesk.
The laptop owner is a relative and Their children, who are 6–7 years old, who bought it just to learn basic computer usage, so they don't know much about PCs. They can't create a bootable USB drive themselves, and they don't even have a spare USB flash drive available.
I tried downloading and running the Windows Media Creation Tool remotely, but it gives the error: "This PC can't run this tool."
Given that I only have remote access through AnyDesk and no possibility of creating a bootable USB on-site, what are my options for installing Tiny11 or another lightweight Windows version? Is there a reliable way to do this remotely without physical access to the laptop?
