Windows Mobile 6.x AKUs
"What is an AKU and why is it important to me?" you might ask yourself.. As stated nicely here:
"Microsoft creates updated builds of the Windows Mobile operation system called Adaptation Kit Updates (AKU). These releases are rarely intended directly for consumers, and are usually a result of some extra features or fixes required by a particular Windows Mobile device. For example, if an OEM (Original Equipment Manufacturer) decides to add a new kind of external keyboard to a Windows Mobile Pocket PC, then some extra driver code will be required - in that case, Microsoft creates an AKU to drive the hardware."
So different levels of the OS could have different features, patches and updates. For an enterprise environment this is of course very relevant to determine issues and resolutions for problems.
How to find the Build and AKU number?
On a touch screen Professional/PocketPC device go to: Start->Settings->System tab->About.
On a non-touch screen Standard/Smartphone device go to: Start->Settings->More->About.
The AKU version is also stored in this registry key: HKLM\SYSTEM\Versions\Aku.
The AKUs are numbered incrementally after the Build number. See the table below for more details and known WM 6.1 builds. It is not meant to be a complete overview.

A listing of older WM 5 and WM 6 AKUs are posted here. And don't forget my previous postings of Windows Mobile 6.1.x Upgrades and Build Levels. :-) That gives a good overview of some of the devices out there and their AKU level.
What is important is knowing the AKU level for specific SCMDM features. In particular the MDM Password Reset Client feature, which can be downloaded from here: http://technet.microsoft.com/en-us/scmdm/cc304591.aspx.
I will go into more details on this feature in my next posting.
