What is this issue? my customer complaine pc after windows update cant connect to network client? i have received 2-3 customer have this issue

den prompt our the error message

you can't access the shared folder because your organaization's security policies block unauthenticated guess access. These policies help protect your PC from unsafe or malicious devices on the network.

some other pc have no update windows yet, dont have this kind of issue,

1st - u can't say need to reformat the whole windows agine, due to customer pc just fully reformate due to virus issue.

***Move from Windows / Windows 11 / Windows update***

    Hello

    I recommend that you use Registry Editor to enable Insecure guest login, see the following steps:

    1. Open Registry Editor. Go to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LanmanWorkstation.

    Note: If the key does not exist, you need to create it. Hold down the "Windows" key (right-click), select "New" > "Key" and name the switch "LanmanWorkstation".

    1. Hold down the "LanmanWorkstation" key (right-click), select "New" > "DWORD (32-bit) Value" and name it "AllowInsecureGuestAuth". Double-click, set "Value Data" to "1", and press Enter.

    Note If you modify the registry incorrectly, you can cause serious problems. So, follow these steps carefully. For additional protection, back up the registry before modifying it. For more information about how to back up and restore the registry, see Backing up and restoring the registry in Windows.
