Logon Performance Enhancements

I’ve been experimenting with logons to try to making them faster for my users, and have come across a way to make the initial profile creation go faster…

- Delete the value “StubPath” under this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}

(I actually renamed mine to BACKUP_StubPath in case I ever wanted to reverse it)

Also change the following key:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}]

Modify it to "IsInstalled"=dword:00000000

This will prevent “Windows Mail” from generating around 14MB of content when the user profile is created (local folder under AppData, not roaming). It seems to be some sort of database thats created and who actually uses the Windows Mail application now-adays? Probably the same number that still use Outlook Express....


It can also be disabled through group policy as well if you don't want to do it via the registry:

CPU Config -> Admin Templates -> Windows Components -> Windows Mail -> Turn off windows mail application - enabled

This change cut about 15-20 seconds off my login times, and undoubtedly saved IOPS as well.
