- Install: SP3, IE8, Windows Update Agent. I use 7.4. Install Windows Update Agent 7.4.7600.226 which is the last one with manual installation. The 7.6.7600.256 has automatic installation but needs the previous agent already installed, so if there is no agent installed you have to start with 7.4. https://support.microsoft.com/en-us/help/946928/information-for-network-administrators-about-how-to-obtain-the-latest (Change en-us to your language as pl-pl?)
- Switch from Windows Update to Microsoft Update:
- Activate Control Panel / automatic updates and it is important to wait about 5 minutes
- http://www.update.microsoft.com/microsoftupdate
- Install ActiveX until it says it has been installed.
- Close IE8.
- Turn off automatic updates.
- Reboot. If it fails to repeat again expecting more.
