Manually disable windows auto update

 Method 1: Using Group Policy Editor (for Windows 10 Pro, Enterprise, and Education editions)

1. 1. Press the Windows key + R to open the Run dialog box.
2. 2. Type "gpedit.msc" and press Enter to open the Group Policy Editor.
3. 3. In the Group Policy Editor window, navigate to the following path on the left-hand side:
   4. Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update.
4. 5. On the right-hand side, locate the policy named "Configure Automatic Updates" and double-click on it.
5. 6. In the configuration window that opens, select the "Disabled" option.
6. 7. Click Apply and then OK to save the changes.

Method 2: Using Registry Editor (for Windows 10 Home and other editions)

Note: Modifying the registry can be risky, so be sure to follow these steps carefully. It's recommended to create a backup of your registry or create a system restore point before proceeding.

1. 1. Press the Windows key + R to open the Run dialog box.
2. 2. Type "regedit" and press Enter to open the Registry Editor.
3. 3. In the Registry Editor window, navigate to the following path on the left-hand side:
   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows.
4. 4. Right-click on the "Windows" folder, select New -> Key, and name it "WindowsUpdate" (without quotes).
5. 5. Right-click on the newly created "WindowsUpdate" folder, select New -> Key, and name it "AU" (without quotes).
6. 6. Select the "AU" folder, right-click on the right-hand side panel, select New -> DWORD (32-bit) Value, and name it "NoAutoUpdate" (without quotes).
7. 7. Double-click on "NoAutoUpdate" and set its value data to "1".
8. 8. Click OK to save the changes.

After applying either of these methods, Windows will no longer automatically download and install updates. However, it's important to note that disabling automatic updates can leave your system vulnerable to security risks, as updates often include important patches and bug fixes. It's recommended to periodically check for and install updates manually or consider enabling automatic updates again after a certain period of time.
