Completely fresh reinstall of Windows 7 Ultimate x64 on a Dell Inspiron 1570 laptop. Using the entire 160 Gb new hard disk, formatted as per windows setup. Installing from a USB stick loaded with W7 installation files purchased from ebay. I am using the SLIC in the machine's BIOS together with a matching xrm-ms certificate file via slmgr.vbs to perform OEM SLP activation - this has proceeded uneventfully and control panel reports 'Genuine Windows'. It absolutely will not download Windows Updates. It just sits there with the blue progress bar going across. And across. And across. For days (I think, in truth, the longest I have left it running for is probably.. 20 hours?) I've tried a number of fixes I've found elsewhere on the net: - running .net_cleanup_tool.exe from Microsoft. It appears to uninstall all .net components apart from those (2.0, 3.0, 3.5?) that are preinstalled as part of W7, and then installing .NetFx35ClientSetup.exe and .NetFx45_Full_setup.exe both from MS. - MicrosoftFixit50123.msi - WindowsUpdateDiagnostic.diagcab - Completely turning off all firewalls - ensuring WU & BITS services are started - running windows_repair_aio_setup.exe from a site called tweaking 'full stop Charlie Oscar Mike' - installing WU standalone installer, Windows6.1-KB947821-v34-x64.msu - installing WindowsUpdateAgent-7.6-x64.exe error messages I have encountered along the way so far: Windows Update error 0x8024402C(2016-04-29-T-07_33_09A); Service registration is missing or corrupt; Access to the path 'C:\Windows\softwaredistribution' is denied; standalone WU installer: Installer encountered an error: 0x8024800c standalone WU installer: Installer encountered an error: 0x8024001e can anyone help me get Windows Update working?
