I've read about the difference between Service Packs and Cumulative Updates but I'm not seeing any official guidance on whether to install CUs as they come, or wait until they're rolled into a SP. Generally a CU is a collection of Hotfixes and the advice for those usually says not to install unless you are suffering from the problem the Hotfix solves.
It looks like this is an 'it depends' question. So:
- Do you routinely install CUs or do you wait for the SP?
- And why?
