Hi everyone. I'm facing a big problem after an Windows Update in a VM with Windows Server 2012 STD and Exchange 2013 installed. After run W. Update the server restarted and failed to install them, then become to revert changes. After some time it took about 4 hours in "Please Wait" screen, all services were working and I could access the server through Windows Explorer. Then I decided to kill trustedinstaller proccess, after that it went to login screen, when I tried to run W. Updates again it didn't work. Then I posted here and a member told me to rename pending.XML file. It worked fine and the server worked fine all week and I could install all updates again. Today I decided to update Integrated Services of this VM it asked to restart the server and the problems came back. Now I'm unable to install updates, rename pending.XML file ( because the keyboard doesn't work when I try it) and the cluster service is not working, but I can access the server cause I used revert function in Hyper-v. Please everyone I really need your help to solve this problem. Thanks!!
