im thinking of a few options, depending on how much control you have over the program
If you have the source code, and know a bit about the language / framework used, you can delete the parts of the program that handle closing / alt-f4 events. Then the only way to close it is via task manager / powershell
Create a script to check if the application is open with `tasklist` / `get-process`, and open the application again if it isn’t. this would just be a .ps1 file that you would run on startup and have it loop every few seconds or so and check the state. i have a script similar to this that you can see if you want or you can ask chatgpt, it’ll be accurate
im not sure exactly how to do this, but I know it’s possible; run the task on startup as an elevated user, and assuming that this environment is configured correctly (aka no-one has local admin perms) you can prevent apps from being closed by setting certain flags inside of the task scheduler.
