Every time you buy a new computer you of course need to install a bunch of software. In my case this would be stuff mostly from MSDN

Visual Studio 2008 + Service pack 1
SQL Server 2008 + Service pack 1
Expression Studio 2
Win XP SP 3 (to run on a virtual machine)
Windows 7 RC (to run on a virtual machine)
Visual Studio 2010 (to run inside the Win 7 virtual machine)
Office 2007 Ultimate

The nice thing about Virtual machines is that you can mount an ISO right inside the machine, this way you don’t have to burn a CD or install a ISO mounter inside the virtual machine itself

If you upgraded from Windows XP to Vista you probably wonder how to mount images. On XP you might have used alcohol or the VCdControlTool provided (but unsupported) by Microsoft. On Vista (and I am running the 64 bit version) you can use MagicISO. If you end up using this tool on a regular basis the I would suggest paying the $29 for it otherwise companies will stop making tools like this.
MagicISO is very easy to use. After you install the program you will see a new icon in the taskbar.

To mount an ISO do the following
In the taskbar right click on the MagicISO button
In the taskbar right click on the MagicISO button

Select the topmost entry labeled Virtual CD/DVD-ROM, click on K: No Media
Select the topmost entry labeled Virtual CD/DVD-ROM, click on K: No Media

After that select Mount
After that select Mount

Now navigate to the folder that you have the ISO in
navigate to the folder that you have the ISO in

After you select the ISO you will see the following dialog box
dialog box

Now you can either run the program immediately or click on the K drive. It is as simple as that. MagicISO has versions optimized for Win 7 and Server 2008 and versions optimized for Vista
