hi, I m getting error 80073712 in win update. i m using win 7 sp1 32bit ultimate. few days ago some updates appeared repeatedly asking to install though every time it show ''installed successfully'' msg after each update. i tried to install them manually offline but it re-appeared again. after few days IE9 became unable to launch. i got error ''no installed updates found in ur computer'' in update folder so i couldnt un-install IE9. Now my windows not getting any updates but MSE gets updates regularly. I tried sfc scannow cmd enabling win module installer service setting to manual from eleveted cmd prompt as well as from repair windows cmd prompt booting from installation disc. But every time it returned me error msg without any scan.'' requested action couldnt be completed due to protection''. I tried ms fixit tools for win update and windows update readyness tools but no luck. Is there any way to avoid re-install of windows in order to solve this problem? please reply/
