Simon and I have been writing a series on managing PCs the modern way recently over on The Register; here's a roundup of most of the pieces I wrote, from helpdesk tools to what's different about managing a notebook to whether you really can let users buy their own PCs (fascinating discussion between users and IT admins in the comments on that one).
The challenges of desktop configuration

Productivity: IT pros to the rescue
http://www.theregister.co.uk/2011/03/25/business_productivity/
Windows support tools
http://www.theregister.co.uk/2011/04/14/windows_support_tools/
Managing the desktop when it's a notebook
http://www.theregister.co.uk/2011/04/12/desktop_management_frameworks/
Automated patch management (I will note this one was edited for length and ends up with an unusually staccato delivery compared to my excessively discursive original)

Your PC our problem
