Personal Vault Will Not LOCK After Windows Update

Question

Personal Vault Will Not LOCK After Windows Update

LGLDSR73-6492 1,480

A few moments ago I just finished Windows Update, "Windows 11, version 25H2 (repair version)" and "2026-07 .NET Framework Security Update (KB5100998)".

I went into my Personal Vault. It is as you can see, Open. In the upper left you can see that it is telling me to Unlock it.

When I select 'Lock' the Door does not close and 'Unlock' appears in the upper left. See screen capture below.

I have logged out and in multiple times.

Please advise and thank you.

Hello LGLDSR73-6492,

I understand that after the Windows update, Personal Vault still shows an open-door icon even after you select Lock.

First, test the actual security status rather than relying on the icon: close Personal Vault, reopen it, and check whether Windows asks for a PIN or another verification method. If verification is required, the Vault is locked correctly.

Restarting OneDrive may also refresh the stuck icon without changing any settings:

Close all files stored in Personal Vault and wait for OneDrive to finish syncing.
Press Ctrl + Shift + Esc to open Task Manager.
Select Microsoft OneDrive, then select End task.
Open Start, search for OneDrive, and launch it again.
Lock Personal Vault and test it once more

If the Vault still opens without asking you to verify your identity, try resetting OneDrive:

Press Windows + R, enter %localappdata%\\Microsoft\\OneDrive\\onedrive.exe /reset then press Enter. Afterward, open the Start menu, search for OneDrive, and launch it again.

Note: Resetting OneDrive does not delete your files. It rebuilds OneDrive’s local settings and sync connection, which can clear a stuck or outdated Vault status and allow the lock function to work correctly again.

Please let me know how it goes after trying these steps, and I'll be glad to continue looking into it with you.

Thank you very much.

I go to the OneDrive icon and View Online. I click on the Personal Vault which is closed. It has me sign in, then prompts me for my PIN. I provide the PIN.

I go to My Files, Vault is open.

I go to Vault ---> Lock.

Vault is open. Upper Left shows "Unlock Vault".

I then click on 'Home' or any other option such as 'Recycle Bin then return to 'My Files' and Vault is locked.

I am wide open for any explanation(s).

Thanks again for your time!

Hi LGLDSR73-6492

Thank you for explaining the situation very clearly.

Since Unlock Vault appears after you select Lock, and the Vault asks for your PIN when you open it again, the Vault appears to be locking correctly. The open-door image may simply because the page has not yet refreshed to show the updated lock status.

My recommendation is to first try the earlier methods, such as restarting OneDrive through Task Manager and resetting OneDrive to refresh the app and clear any stuck local status information that may be preventing the Vault icon from updating correctly.

Please let me know how it goes afterward, and I’ll be happy to look into this further with you!

Thank you so much for your patience!

Yours sincerely.

Thank you, Norah-L.

This is strange...

I went to I went into Task Manger and ended the process for OneDrive.
I then relaunched OneDrive.

I went to View Online.

I unlocked the Vault but this time I locked it from within the contents of the contents of the Vault.

I then went to My Files and Vault showed as Locked.

Previously I had exited the contents of the Vault, went to lock the Vault but it showed as open unless I first clicked on Recycle Bin, Home or some other Icon. Then the Vault would show as Locked.

Any thoughts on that? Thank you very much for your time, greatly appreciated!

LGLDSR73-6492,

Thank you for testing that and sharing how it goes.

What you observed supports the idea that the Vault itself is locking correctly, but the My Files page does not always refresh the Vault icon immediately.

When you select Lock while still inside the Vault, OneDrive returns you to My Files, which reloads the page and displays the current locked status. When you first return to My Files and then lock the Vault, the lock command is completed, but the existing Vault tile may continue showing its previous open state until another navigation refreshes the page. This is the most likely explanation, although I could not find official documentation confirming this exact visual behavior.

Restarting OneDrive may also have refreshed the connection, but because this occurred in View Online, the different locking path is probably the more relevant factor. For now, locking it from within the Vault appears to be a suitable workaround. If the Vault requires your PIN when reopened, your files remain protected.
