Since you're on Windows, did you defragment your disk after updating to build 1200? (Generally, run a defrag after any major software update - Windows Update or other.)
I assume you're talking about the time it takes to get to the startup dialog (open previous/new project, etc) - in which case libraries have not been scanned yet. Or, are you talking about the time it takes to load a project?
Do you Norton or some other virus protection software that you've recently updated, and which is scanning each program as it is opened? Consider disabling that option if you are always careful about what programs you launch and have done a full scan and scan all incoming files.
