Adding more disk space to a Windows virtual machine in VMWare is very easy.

All you have to do is the following:

Power down your virtual machine

1. In your VMWare manager (vSphere, etc.) edit the VM’s settings
2. Increase the provisioned size of the disk and click OK
3. Power on the virtual machine
4. Verify in Disk management that the VM sees the new unformatted disk space
5. Open a command prompt (In Vista/2008 as Administrator)
6. Run diskpart
7. Type list volume
8. Type select volume <volume number>
9. Type extend
10. Type exit

That’s it. No live CD. No nothin’! Just more disk space!
