Have a user who's pc keeps locking up, we've tried re-imaging, replacing, but still has the issue. What we are seeing in his roaming profile is his temporary internet files folder is collecting a bunch of spreadsheets for some reason, they are located in sub folders called 'Content.MSO' or 'Content.Word' or 'Content.Outlook'. Some of these files are 100mb in size and I got a feeling this is what's causing it. Where is the setting to change this?
