Ho Hum

I never promised I’d keep this blog interesting.

I use VHD boot to keep multi-boot setups clean without to create having multiple partitions on my primary disks. There’s minimal performance drop and the only functionality I’ve really noticed you lose is hybrid sleep which I use on my laptop.

One of the pains with it is that though you can create the VHDs as expandable, by default Windows will expand them out to their full size during boot. This can be disabled in the registry but I always forget where, so yertis:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\FsDepends\Parameters]

“VirtualDiskExpandOnMount”=dword:00000004

Very parochial stuff, of no interest but the utterly geeky with a bent for Microsoft isometric diagrams in Visio:

Microsoft’s 3D server stencils are transformed by 28.55° not 30° used by most isometric diagrams, and I think that equates to 1 down, 2 across in a grid that is 2.5mm by 2.72mm, but my trigonometry has failed me…

Great, got that off my chest.

I know why MS have turned TCP IP v6 on by default in Vista and Server 2008, I just don’t use it and don’t need it turned on – it makes ipconfig really messy. You can’t uninstall it, and even de-selecting it in the NIC properites leaves it there, but you can disable the tunnelling interfaces that pop up in ipconfig, or even disable it completely.

This article just about says it all http://www.mydigitallife.info/2007/09/09/disable-and-turn-off-ipv6-support-in-vista/, but just to jog my memory all that’s needed is to add the ‘DisabledComponents’ entry to HKLM\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters and set it to 1.
