Hi ArrowJade453
I am Dave, an Independent Advisor, I will help you with this . . .
If you are using the Microsoft Store version of Minecraft, then that is installed in its own folder inside C:\Program Files\WindowsApps
The WIndowsApps folder is the most protected folder on Windows 10 and you will not be able to access that
Open Task Manager, then choose the Processes Tab
Right click any Column Header on the Processes Tab and turn on the Command Line Column
Resize that column very wide
Start Minecraft, the on the Processes Tab find Minecraft, expand that and you should see the full path to the executable
