"A required privilege is not held by the client" because of an "Account unknown..." in the Local Disk (C) Properties...??

Eamonn · 2024-06-30T00:38:52-0400

Hello,

on Friday 28th June I was able to download programs, images, etc... to the Local Disk (C) drive on my PC. On Saturday 29th... I tried to download another program to the Local Disk (C) drive but was unable to so, and I got this popup... "A required privilege is not held by the client."

There is now an "Account unknown..." in the Local Disk (C) Properties...??

I have tried to get rid of it but nothing is working...

The only difference from Friday's download and Saturday's attempted download... was that on Saturday morning I logged into my Microsoft account (for the first time since Windows 11 Pro was installed).... then later on Saturday, I began to download programs only for it not to allow me permission into the Local Disk (C) drive.

I can use all the other drives... just not the Local Disk (C) drive. What is going on here.

Invoked encryption? Check to see if Bitlocker is (now) activated.

This is what I've found... just turn everything on?

No

Check Settings > Privacy & Security > Device Encryption. Should be "Off"

I'm in there now but can't see, "Device Encryption"...

Sorry, that's a puzzler. May be not what I was thinking initially, but that setting should still be there.

I even used the search function within Settings and it returned "no results found".

I found this though...

To turn on Windows device encryption

Sign in to Windows with an administrator account (you may have to sign out and back in to switch accounts). For more info, see Create a local or administrator account in Windows 10.
Select the Start button, then select Settings > Update & Security > Device encryption. If Device encryption doesn't appear, it isn't available.
If device encryption is turned off, select Turn on.

I would right-click on the file, select Properties->Security->Advanced and make sure the Owner is Administrators (the group, not the built-in account). If it isn't change it to that. Then In same section click to modify permissions, delete the unknown user entry and make sure that Administrators have full access to the file. Now you should be able to do whatever you want. If this happens at a file in some folder you might have to change owner to Administrators at the containing folder and also grant full access to Administrators for this folder, subfolders and files.

I strongly caution against arbitrarily changing permissions just because you have the presence of this 'unknown account.' Your issue may well be something else.

The Account Unknown with SID (security identifier) indicates the User Profile which no longer exists. You can see this when an account may not have removed correctly.

I also have an "account unknown" in disk properties too. I can't say for sure which action caused it but I believe it was left behind either when I established a local test account and later removed that account or when I changed the name that appears on the login screen to be my name rather than my MS account email address.
I have not tried to get rid of this unknown account in disk properties as I believe in leaving well enough alone since I'm having no issues.

Account Unknown?

On my main Windows install I have an Account Unknown showing in Security tab for the C: drive. It also appears on all 3 of my VirtualBox machines. All machines are running Windows 11 22H2 with one of them on Dev channel. The full number is the same on all PCs...

Hi,

I can't leave it alone as because of it I am unable to get permission to use the drive... I am unable to download anything to my Operating System Drive.

In the video I've just attached

the guy talks alittle about the problem. In the comment section someone mentions "Unknow accounts" popping up when you sign into your Microsoft account for the first time after a fresh install of Windows... which I did on Saturday... The drive was working as intended on Friday.

Windows was installed at my PC shop a few days earlier to Friday. It was working as intended on Friday. The old thing that changed on the New PC was, on Saturday, I logged into my Windows account... then I didn't have permission any more to use the drive.

I had not deleted any accounts for this to happen in the first place.

Could this happen if you did not originally use a windows account to sign in when you installed windows, and then later signed in with a windows account?

Possibly but I've seen it when a user was deleted but it didn't get cleaned up.

Eamonn · 2024-06-30T14:26:25-0400

Yesterday, I deleted the unknown account. Then restarted my PC.. now I've the old unknow account and a new one

Do you not have an image you can restore from before the issue first occurred?

I really do not think this unknown account is what is preventing you installing anything. I would bet your user account has become corrupted. Of course, there always a chance Windows itself is corrupted.
You can prove if it's your account by creating another local user account with administrative privileges and attempt to install something. If you have no issues in the new account, your user account is corrupted.

How to create a new account.
If you have autologon set to on, you will need to disable it.

1. (HOME) As a precaution, Turn off device encryption if it is currently on. Turn On or Off Device Encryption in Windows 11 Tutorial
(PRO) turn off standard Bitlocker. Turn Off BitLocker for Drive in Windows 11 Tutorial

2. Create a new local account
Settings>Accounts>Scroll down and click on Other Users.
Select add account>select I don't have this person's signin information
This will let you create a local account
In user name box name the account and assign a password
Very Important- Make the new user an administrator. After account is created, to the right of the new user name click down arrow. Select Change account type.
Click arrow to right of standard user and select Administrator
Restart and login to the new account and install something
Try that, and report back your findings.

Thnaks,I'll look into this... and see what the results are.
