I guess that backing it up and reformatting might do, but it too 3 or
4 days to install it including all recent patches, some language
installations just to get that plain empty system I would not

installed (OK: MS Developer Studio).

Undoing: how can I undo a volume extension?

Hi, Christian - I'm sorry that I don't have a direct answer to your
question, but I do have two suggestions:

1. VMware gives you the ability to take snapshots of virtual machines. In
effect, this gives you a complete image of the vm at a specific point in
time. So next time before you make any big changes, take a snapshot because
restoring to the working vm is a no-brainer.

2. You might want to post your question on the VMware user forums. They are
very active and helpful.

Good luck,

Malke
