The page file disk defrag, and performance settings are key. For pagefile it doesn't need to be big and it should be a fixed size. Performance settings include visual effect degradation for sure. All of this can also be controlled with GPO, including the preferences. Preference GPOs can largely replace logon scripts. Some of Olav's favorites include a registry wizard in GPO fir Server 2012. Browser is built right into the GPO tools. The targeting editor allows hardware and software queries with WMI and such. He likes the GPO for creating a local user such as a local admin. All of this is in Preferences>Control Panel, explore a bit. Combining things like the local user creation, and the WMI filtering (maybe via the targeting editor) we can make some pretty dynamic use cases.
So there was some pretty good stuff in here, but soooo disorganized. Sorry for being all over the place- the instructor was as well.
