Fix: UAC YES Button is Gone or Grayed out in Windows 10

April 21st, 2020 by Admin

When you try to open a program as administrator, the User Account Control (UAC) dialog will pop up as normal but the Yes button might be missing or greyed out.

This problem usually happens when there is no other administrator account exists in the system and your account no longer has the admin rights. In this tutorial we’ll show you an easy way to fix such UAC privileges problem.

How to Fix: UAC YES Button is Gone or Grayed out in Windows 10

  1. Open a Command Prompt window without admin privileges. Type the following command and hit Enter.
    SHUTDOWN /R /O -T 00

  2. The computer will log you off and bring up the Choose an option screen. Click on Troubleshoot.

  3. Select Advanced options.

  4. On the next screen, click on Startup Settings.

  5. From the Startup Settings window, click on Restart.

  6. Once Windows restarts to the Startup Settings screen again, press 6 or F6 to choose “Enable Safe Mode with Command Prompt“.

  7. Although the built-in Administrator account is disabled and hidden, it will still show up on Safe Mode login screen. You can click it to login without a password.

  8. Once logged in, the Administrator Command Prompt will open. To fix the problem of “Yes button missing or grayed out in UAC”, type the following commands one by one to change your password, prompt your account to administrator and make it active.
    net user YOUR_USER_NAME YOUR_NEW_PASSWORD
    net localgroup Administrators YOUR_USER_NAME /add
    net user YOUR_USER_NAME /active:yes

  9. Reboot your computer as normal and everything should be good to go.

If you have previously set a password on the built-in Administrator account and you can’t remember it, the above method won’t work and you can use PCUnlocker to reset your password and account settings, which will also make the “Yes” button in UAC dialog become accessible.

2 Ways to Prevent NTLM Credentials from Being Sent to Remote Servers

April 14th, 2020 by Admin

When you try to access a web page which contains a file hosted on a SMB server, Windows automatically sends your user name and NTLM credentials to authenticate. Although the credentials are not sent in clear-text, the attacker can crack them to recover your Windows password. To avoid leaking your account credentials, you can block NTLM (allowing only Kerberos) so Windows will no longer send your NTLM credentials to remote servers.

Method 1: Restrict Outgoing NTLM Traffic Using Group Policy

  1. Open the Local Group Policy Editor and navigate to: Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options. On the right pane, double-click the “Network security: Restrict NTLM: Outgoing NTLM traffic to remote servers” policy.

  2. Select Deny all from the drop-download list, click Apply and then OK.

  3. Reboot your computer and Windows will no longer automatically send your NTLM credentials to a remote server when accessing a share.
  4. If you need to add some remote servers to a whitelist, double-click on the “Network security: Restrict NTLM: Add remote server exceptions for NTLM authentication” policy.

  5. Add the remote servers to the list of exceptions, click Apply and then OK.

Method 2: Restrict Outgoing NTLM Traffic Using Registry Tweak

  1. Open Registry Editor and browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0. Right-click on the MSV1_0 key, select New -> DWORD (32-bit) Value.

  2. Name the newly created DWORD RestrictSendingNTLMTraffic, then double-click it to set the value data to 2 and click OK.

  3. If you want to add certain servers that you wish to whitelist, use the similar method to create a new DWORD named ClientAllowedNTLMServers. Double-click it and add remote servers which you allow sending NTLM credentials to.

  4. Reboot your computer to apply the changes. You can continue accessing files on remote servers which are whitelisted while stopping Windows from potentially sending your NTLM credentials over the network.
