Thanks to informations found here, I removed telemetry and W10 related KBs from my W7 computer. However, Windows Update got broken in the process : it now fails to download any further updates and puts a 100% load on the CPU. The Windows Update Troubleshooter (kb2714434) cannot fix it and insistently reports a 0x80070057 error. Various Microsoft "fixit" scripts related to that error failed to solve it too (kb929833; kb947821; kb968003; kb949104; kb2700567). Sorry for not providing links to these KB but the editor of the forum prevents me to do so. What should be my next steps ? Fix Windows Update in order to keep my computer in the mainstream ? That's what I would prefer to do. What is the right place in the forum to ask for support on that issue ? Resign from using Windows Update altogether and start to install manually the next updates ? Is it realistic ? How to check Microsoft repositories for new updates ? Thanks for any guidance.
Hi, The only restauration point which is available is January dated. The removal of telemetry KBs was done in december. No way to go that direction, unfortunately. Furthermore, sfc /scannow has been one of the first step I went through; it shows no error at all.
Search for Microsoft online update repair tool. They have an online tool to do repairs to windows update. Will solve most problems.
Thanks Dewot. It has been done before I posted. The tool is called Windows Update Troubleshooter. It reports error 0x80070057 bait fails to fix it.
