A bug was introduced in Configuration Manager 2012 R2 Sp1 which caused driver bloat when using the Import New Driver wizard, and below is a typical example of that.
Using drivers for the HP Z420 Workstation:
- with SCCM 2012 SP1, the Source Size 532MB, Package Size 532MB
- however with SCCM 2012 R2 SP1 CU1, the Source Size is still 532MB, but the Package Size is a whopping 12356MB
Microsoft has released a fix, listed below.
When you add new drivers to a driver package by using the Import New Driver wizard, the driver package files are larger than you expect.
The content for the driver package may be duplicated multiple times. This causes the package file to be significantly larger than the package in the original source location.
Additionally, the process to import the new drivers by using the Import New Driver wizard may take much more time than you expect.
