Account Unknown(S-1-15-3-65536-1888954469-739942743-1668119174-2468466756-4239452838-1296943325-355587736-700089176)

What did you do after that

Account Unknown(S-1-15-3-65536-1888954469-739942743-1668119174-2468466756-4239452838-1296943325-355587736-700089176

Unknown accounts are called "feature SIDs" and are there to provide permissions for applications. For example, the S-1-15-3 one could be associated with Nvidia. It is not recommended to delete them.

The reason it appears this way is because the system can no longer find a friendly name for the account and by default just moves SID to the full name.

However, to see who the real users and administrators of the PC are, you can do a further check by typing in the search bar: "netplwiz" without quotes obviously, check if that user appears there...

The request to send feedback about this unknown account was made by an operator named Napoleon from Microsoft support. Give feedback It's important! The strength of the group is already demonstrated within nature...

Wrong. “feature SIDs” are shown as Unknowns, but you can't say, either an Unknown is a “feature SID” or not, even if it looks like a “feature SID”. Even if it is a “feature SID”, you cant figure out what feature is it, where it came from, you cant figure out that you need a “feature” and cant control “feature”. That is a problem, not the “feature SIDs” by itself.

Thank you for the correction, Jar J Binks (Wrong. “feature SIDs” are shown as Unknowns, but you can't say, either an Unknown is a “feature SID” or not, even if it looks like a “feature SID”.

That is a problem, not the “feature SIDs” by itself.), it is important to always try to be as clear as possible, in the SIDs in question I only hypothesized that it could be associated with Nvidia, however I want to be clearer still, correct me if I'm wrong:

Each part of the SID has a specific meaning:

S-1: The constant prefix indicating that this is a security SID.

15: Identifies the revision level of the SID.

3: Identify the security authority.

The other numbers represent the unique identities assigned to the specific security object.

The SID in question

(S-1-15-3-65536-1888954469-739942743-1668119174-2468466756-4239452838-1296943325-355587736-700089176), seems to be a randomly generated SID, I didn't find any clues about it, however, I think not it's a good idea to delete it without knowing what it is exactly, support has asked for feedback on this SID, it seems like a good start, then.

It seems like a good thing to see who the real users and administrators of the PC are, you can do a further check by typing in the search bar: "netplwiz" without quotes obviously, check if that user appears there...

Daniele, do you really think that we shall look for a issue on feedback hub using this poor directions?

Please use “share” feature of feedback hub and provide us with direct link to the issue.

It looks like you haven't read this thread from the beginning. If you look at my post on May 18, 2023, you see direct links to the three issues on feedback hub, all concerning “Account Unknown” problem. I already sent a feedback, why should I care about Napoleon? And what changed?

And, please, stop copy-pasting your own posts. What makes you think I was unable to read your words first time?
