ConfigMgr R2 SP1 upgrade does not clean up previous Cumulative Update entries in Control Panel > Programs and Features
Just a quick blog post on a small anomaly with Configuration Manager R2 Service Pack 1.
When upgrading an existing Configuration Manager site it seems the Installed Updates entries related to prior Cumulative Updates are not properly cleaned up. After upgrading a site the end result for Installed Updates looks like this:
The above example is based on a site that was up to Cumulative Update 5 – but the same happens with earlier released Cumulative Updates.
Although this is not really an issue and more cosmetics, it is something that could have been handled more properly by the Service Pack installer. A scenario where this potentially may cause unwanted effects is when using this information in your queries (collections, etc.).
The entries displayed are read from the registry. The screenshot below shows the entry in the registry for the particular cumulative update:
I used the following steps to clean this up:
- Start the Registry Editor (regedit.exe)
- Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall .
- Locate the key for CU5 (see screenshot) and take a backup (right-click > export).
- Delete the key for CU5.
- All done – the entry is no longer displayed.
Note that this cleans up the cosmetics part only – any other leftovers (if any) from Cumulative Updates (and alike) will still remain on the system.
Until next time!
