64-bit only OS Deployment and 64-bit Client
SCCM should have a native 64-bit client. With most computers having more than 4GB of RAM, 64-bit should be the only deployment option available. Like Apple, it's time for 64-bit only!
We have had a 64-bit native Configuration Manager client (CCMEXEC) since Configuration Manager 2012.
