Error 13 the data is invalid

After applying patches on server 2012, host of exchange 2013 I got Windows Process Activation Service cannot start, Error 13 The data is invalid and a lot of errors containing c:\Windows\system32\intesrv\config\applicationhost.config Line number: 1 Error:Configuration file is not well-formated XML. A lot of other services didn’t started as well

Net.Tcp Listener Adapter
Windows Process Activation Service
World Wide Web Publishing Service

and few other

The solution turned to be simple – replace the applicationHost.config located in

c:\Windows\System32\Inetsrv\config

with the latest backup file located

C:\inetpub\history

That’s all, thank you glazenbakje
