Copy and pasted as I dont think I can post external links here....
To change the name of a process in Task Manager, you only need to change the name field displayed in the program's properties.
Right-click an empty space on the taskbar. Click "Task Manager." Click the "Processes" tab.
Click "Image Name" to sort the processes alphabetically. Right-click the process you want to rename, then click "Properties."
Right-click the process once again, then click "End Process." Click "End Process" once again.
Return to the "Properties" window. Select the "General" tab. Erase the name of the process, but leave the file extension
Enter into the box the name you want to change the process to. Do not change or delete the file extension
Click "Apply," then "OK," to change the process name.
I tested this method before posting and it works. The only issue I had was that I had to tick "show processes from all users" to have permission. Hope this helps!!
