Windows 10: Is it safe to delete the system managed account named 'DefaultAccount'

Yes, and confirmed by @Kari's link. But note the accompanying warning!.

That just leaves us with the question that started this thread: What on earth is the purpose of the (undocumented) DefaultAccount ?

 

That seems to be a copy of the native built-in administrator profile, not copy of default user profile as you might logically think. It is totally useless, not required, yet it is sometimes shown even if you check existing user profiles with net user command or in advanced user control panel netplwiz.

A very interesting detail is that I've seen the name of this profile written in two different ways, as defaultuser() ( with ( and ) at the end), and as defaultuser0 (with digit 0 at the end).

If it is shown with net user, I always remove this user before removing the folder. Even when not shown in net user I do not remove the folder after first boot to desktop; I am too old school, have seen too much so what I do is I first check if it is shown as user and remove if yes, then reboot and only then remove the folder.

 

That's not quite what I asked, I'm puzzled by purpose of the built in (but disabled) account DefaultAccount which (as far as I can see) doesn't have an associated profile.

 

It has no purpose. There's obviously a minor bug in system, a useless and irrelevant profile will be created for no valid, factual reason.

It's like asking what is the purpose of Settings app sometimes just suddenly closing when you click it, not working, forcing you to re-open it. No purpose, just a bug.

 

Hi again.

Kari, mystere and Bree. I thank you all very much for taking the time to explain things in such detail for me. It's really appreciated.

I'm tinkering with quite a few systems at the moment and also looking forward to buying some new components to make a new desktop PC for myself.. hopefully next month.

All your valuable info will certainly go a long way to helping me understand and configure my new system exactly the way I want it to be.

I'll try and remember to report back and update you all on how things are progressing.

Many thanks once again.

Best wishes *Smile
