Windows 10: Is there a way to change the primary user on my PC but keep all the files and apps?

I originally set up my laptop with my son's Microsoft account. He's not using it anymore, and I want to change to mine. I've been using it for a couple years now, and want to keep the Office 365 apps along with all of the files and documents. Is there a way to do that?

How to change default app for file type

@Bree - yes, I'm quite aware of this thanks, but as you will see it's missing. I recall reading that clicking the dialogue at a certain point in blank space made it appear, and trying that once successfully, but doesn't seem to help now. Plenty of other similar reports of this option being missing.

Change primary alias

Hello,

Thank you for your reply,

As per description, when you click to change the primary on nothing happens.

Have you tried to perform the troubleshooting steps provided under section
Change which alias is primary ?

If you have not performed the troubleshooting steps I would suggest you perform steps under
Change which alias is primary , from my previous post. Which are as follow.

• 
  If you already have the latest version of Internet Explorer, get more info on how to
  
  reset your browser.
  
• 
  If you're still getting the error, check to see if you have the
  latest version of Silverlight.
  

Note: The Reset Internet Explorer Settings feature might reset security settings or privacy settings that you added to the list of Trusted Sites. The Reset Internet Explorer Settings feature might also reset
parental control settings. We recommend that you note these sites before you use the Reset Internet Explorer Settings feature.


Please do let us know if you need further assistance with Windows.

 

How to change default app for file type

'Open With > Choose another app' has three step, in the first it only offers apps registered for that file type. If you click 'More apps' it lists all registered apps regardless of suitability. Both these steps have the tick-box for 'Always use...' in my 18363.752. The third step, if needed, is 'Look for another app on this PC'. The 'Always use...' must be ticked before taking this step if you want the change to stick. However, WMP appears at the second step.

For a quick look at a JPG almost anything (including WMP) is more practical than Photos which on my system takes more than ten seconds just to open a photo. The OP is probably not aware that the Windows Photo Viewer is still available in W10, but hidden away. That's my default viewer for JPG.
