Are System Center VMM Update Rollups Cumulative?

Hi,

We've had this long running argument for years now on whether Microsoft Update Rollups are cumulative.

Part of our team believes they are while the other part thinks otherwise.

Adding confusion is the varied internet articles that aren't sure either. There are articles that say Microsoft Update Rollups ARE cumulative for some products while others seem to refute this.

Where it concerns VMM 2012 R2, we've been running Update Rollups at customer sites with the assumption that they ARE cumulative. For example, we recently installed Update Rollup 7 on a System Center VMM 2012 R2 UR5 installation with the assumption that the fixes for UR6 are already included in UR7.

Could someone for Microsoft settle this once-and-for all for all of us.

1. Are System Center VMM 2012 R2 Update Rollups Cumulative?

2. Are Microsoft Update Rollups in General Cumulative?

Thank you in advance for the feedback.
