system description TOSHIBA Laptop, Model L505-S59903, Intel Core 2 T6500 @ 2.1 GHZ, with 3GB memory Windows 7 Home Premium 32-bit, SP1, newly installed 8/16 installation dvd was burnt from Digital River .iso for win 7, Home Premium 32 bit SP1 Win 7 Product key has been activated Reason for Reinstall Laptop picked up a serious virus that McAfee missed. The virus destroyed system services and system restore points. No hardware changes have been made. Currently system does not have anti-virus installed but windows firewall is active. I did install and remove MSE. No problems were found. Problem Description After installing windows I used windows update (WU) to install the first group of about 10 updates. About 4 installed before a reboot was required. After that 2 more installed and the rest failed with the 80070570 error. In subsequent groups of 10, about 2 of 10 would install with WU. I restarted WU and had a group of 55 updates to download and install. Several installed but about 50 failed with the 80070570 error. Corrective actions attempted sfc chkdsk clean boot Numerous uses of Mr. Fixit Update Readiness Tool Manually reset Windows Update Components per the steps provided in KB 971058 To rename the catroot2 directory I had 2 stop the cryptsvc service. Some of the registry steps failed because of bad or missing entry points into the dlls. Some of the registry steps failed because the specified DLL was missing. I have been able to manually install most of the updates using Windows Download Manager. In all, about 21 updates installed with WU and I used Manual Download/Update for 57 updates all of which failed WU with the 80070570 error. I have also tried reinstalling win 7 and using win 7 RTM iso instead of a SP1 iso. This produced very similar problem but many more updates to load. The systems is back with the SP1 iso installed. I have tried using WU to install single updates or in small groups. About 2 of a groupf 10 will install with WU. The results are repeatable, the same ones loaded or failed with WU. (Over multiple Win 7 installs). All the updates are installed now except for the following: Security Update for Windows 7 (KB2705219) Security Update for Windows 7 (KB2712808) Security Update for Windows 7 (KB2731847) Update for Windows 7 (KB2729094) The Manual Download could not find these in Download Manager! I can provide a list of updates that had to be manually loaded (57 total).

Hi, I suggest you can try to manually download these update from Microsoft Download Center and install it in Clean Boot mode to check the result. Hope this helps. Vincent Wang TechNet Community Support
