    Default Upgrade Win7 to Win10 - Fix error: SAFE_OS, INSTALL_UPDATES, 0x800f0955 - 0x20003

    When I tried to upgrade Windows 7 to Windows 10, I got this error every time: The installation failed in the SAFE_OS phase during INSTALL_UPDATES, 0x800f0955 0x20003

    I tried many solutions to solve this problem but none of them worked.
    Based on the information I found on the internet, I tried a simple solution that no one had proposed before and it worked.



    You have to uninstall SNMP.

    Step 1: Open control panel
    Step 2: Navigate to programs and features
    Step 3: Click on "Turn Windows features on or off"
    Step 4: Disable "Simple Network Management Protocol(SNMP)"
    Step 5: Click ok

    After that upgrade Win7 to Win10 went without any problems.

    Maybe this help for someone.

    Default

    Instead of uninstalling SNMP, there is one more method.
    I advise people to use that.
    Go to the official Windows 10 page and download the installation media for Windows 10.
    Then upload the Windows 10 image to the media and install Windows 10 from there.

    It installs Windows 10 without any problem.
