Windows 10: How to run extended memdiag via bcdedit? What is the proper syntax?

I understand how to run a standard memory diagnostic as follows:bcdedit /bootsequence {memdiag}On the next reboot the computer successfully runs a standard memory diagnostic.What I would like to know is what is the syntax to make this an extended test?I see from this site and this site "testmix" is the switch to modify but nowhere is the proper syntax/usage shown.

MemDiag apearing in system task tray after running it and rebooting

So I ran a MemDiag a few days ago and everything came up fine, upon rebooting I noticed the MemDiag icon was still in the task tray and I was unable to click or right click on it. I've checked in my task scheduler and there is no task that boots up the
memory diagnostic tool, and there is no startup item for it in the system startup list. I can close it with task manager, but with each reboot it appears. SFC /scannow shows there are no integrity violations. So my question is, how do I stop MemDiag from appearing?
I've also tried
bcdedit /bootsequence {memdiag} /remove but it didn't work

***EDIT Was able to fix the issue by running the Memory Diagnostics again and then cancelling it

 

Getting: Syntax Error (Syntax Error)

Hi,



It's possible that you're receiving the Syntax Error due to program incompatibility. We'd like to learn more about your concern so we could
provide the proper resolution. We just have a few questions for you:

• 
  Have you checked with the software manufacturer if this particular software is compatible with Windows 10?
  
• 
  Which version of Windows 10 is on your computer? To check, click
  Start, type winver, and press Enter.
  
• 
  Since you mentioned that you couldn't read anything from the application when you're trying to install it, is there an English version of the game that you can install instead?
  
• 
  What is the name of the game?
  
• 
  Have you checked if your computer meets the game's system requirements?
  
• 
  What troubleshooting steps have you tried so far?
