Cumulative Update 1 for System Center Operations Manager 2007 R2 is here

A long awaited cumulative update CU1 for SCOM 2007 R2 has been released.
First of all it can be downloaded at
Make sure to read the readme’s and the KB article over here:
Make sure you make an upgrade plan for the components installed everywhere.
I have already upgraded a few installations now, so some things to take into account when deploying this update:
When you get a popup asking you to restart now, just click NO first even it appears to be in the removing backup files stages already.
After looking through Kevin Holman’s install notes it appears the installer is not yet done when this popup occurs. I also see the installer still running and taking processor time in the background and after a minute suddenly the hotfixes appear in the agentdeployment directories as well. So click NO when asked to reboot and give the server a minute more to complete some tasks.
After a while I got the notification popup with an error, saying the system has to be restarted etc. Clicking OK returns you to the wizard. After this the system can be restarted.
remember the manually installed agents or the ones that are deployed by some other means (SCCM for example). Also Gateways (remember to check the agentdeployment directories). Consoles installed locally on all kinds of workstations and systems management servers have to be upgraded as well and are easily forgotten.
