I have 3 machines out of about 12 that are having continuous application hang issues which are mostly coming from MS Word and Adobe. All machines are running Windows 7 X64 sp1, Office 2010 Pro plus, and latest version of Adobe Reader. I did find that every time the issue occurs it stems from a custom app we use which hands off a job to either Word or Adobe for printing (printers directly connected to PC) I used resource monitor when the program hung and in the analyze wait chain splwow64.exe process seemed to be the consistent cause of the hang. I downloaded a hotfix from Microsoft which kills the process, but now the programs still hang with no sign of splwow64.exe holding it up. I have switched printers, ran windows update, ran office and adobe repair, but still having issues. Anyone ever see this issue or have a suggestion?
