From Command Prompt (admin), run:

reg add "HKLM\SYSTEM\CurrentControlSet\Services\DoSvc" /v Start /t REG_DWORD /d 3 /f

Post the output.

Restart Windows and check for updates.

    2. Right-click on the batch file, click Properties, click "Unblock" (if present), and OK.
    3. Double-click the batch file to run it.
    4. After it completes execution, don't close it yet.
    5. Right-click on that Command Prompt window, click "Edit" and click "Select all"
    6. Right-click on that Command Prompt window, click "Edit" and click "Copy" (This copies the output to the clipboard.)
    7. Paste the info (Ctrl + V) into your reply window.

    Please upload your CBS logs to OneDrive or GoFile.io for analysis.

    The logs are available in the following folder. Copy the following folder to the desktop.

    c:\windows\logs\cbs

    Zip the folder and share the file on OneDrive or GoFile.io.
