Hello all. I am new here and luckily found this site. My issues are: on 2-2-13 I went to MS update to dnld. items. I have AU, but went there to see if any new items were of interest. There was 1 critical item and 2 optional items. I clicked all and they dnld. Afterward, update kept giving restart warnings to finish dnld. Restart didn't stop notices. Then, I found two of the items did not match my OS. They faild, and now AU will not work, I cannot access WUD from updater and AUD will not respond.When I go to updates from start, it blocks access with the restart notice. I downloaded and ran Fix WU Utility, but have same issue. Get error code 80070BC9 and KB2754295. Have run Malwarebytes, Tweeking Windows Repair, MS Fix It- still have restart blocking AUD. If I try to open the wuapp file, it gives me the notice to restart. Sorry if this post is so windy. Have put hours&hours on fixes. Any ideas & help is greatly appreciated. If I am in the wrong forum, please move to correct one. Thanks, Rod
