CRM Update Rollups and Hotfixes and Updates That Must Be Enabled or Configured Manually
I am seeing more and more clients with Rollups installed but not having done the manual changes following the installation. Customer Effective has a great article on this and I believe is worth publishing here.

You are probably aware that approximately every 8 weeks Microsoft releases an Update Rollup, a cumulative set of updates and fixes.
When deploying an Update Rollup, it’s important to realize that update rollups include two categories of updates:
1. Bug fixes—these are fixes to issues where CRM is not working as designed, and they are applied automatically when you install the update rollup.
2. Design changes—these are updates where CRM is working by design, but Microsoft has made a change in the way CRM works. For example, there were recently some updates that changed how CRM handles housekeeping of completed system jobs. Design changes require a manual change on the CRM server, typically a registry change, to enable the update, since Microsoft doesn’t want to change the system design for users who expect it to work the way it was originally designed.
The changes that require a registry change to enable are included in knowledge base article for the update rollup under the section “Hotfixes and updates that you have to enable or configure manually.”
This is why it’s important to read the knowledge base articles associated with CRM update rollups before you roll them out. Read through the changes included. I only make the changes that require registry changes if the fix addresses an issue that I’m seeing in my environment. Making changes that fix issues that you are not experiencing can have unintended side effects. It’s ok to pick and choose which ones you enable.
This is also why, if you read a blog or hear somebody from Microsoft say “Rollup X fixes that problem,” don’t automatically assume that the problem is fixed because you have installed the update. Read the small print—there may be additional steps required to enable the change.
