In my case OWA also got broken and it left all services disabled.
Solved it with:
Change all "Microsoft Exchange...." services back to Automatic Startup
(Microsoft Exchange POP3, IMAP4, Monitoring and Server Extension for Windows Server Backup are set to manual by default - you might want to keep them that way)
Change the following (non-"Microsoft Exchange") services back to Automatic Startup:
- IIS Admin Service
- Microsoft Search (Exchange)
- Remote Registry
- Windows Management Instrumentation
- World Wide Web Publishing Service
That got me up and running with UM, mail flow and Outlook clients connected, but OWA was still broken with the following symptoms:
When simply applying the Update Rollup 4 for Exchange 2010, you might end up with a blank logon screen at your CAS servers when you want to reach OWA.
When opening up the details of the error message, the following text is shown:
Message: Syntax error

How to solve it?
Stop all "Microsoft Exchange..."
(In my case also: Backup Exec and Symantec Mail Security for Exchange)
Start an Administrative Exchange Management Shell
Type ii Exchange2010-KB982639-x64-en.msp
Close the Exchange Management Shell and finish the patch.
