Drag and drop

Right, but unless you've disabled UAC then you're not really running
with admin privileges. If you disabled UAC then both your desktop and
VPC are running with administrator privileges. In this scenario you
should be able to drag and drop.

A simple way to see if you're actually running with admin privileges
is to open a cmd prompt, if you see "Administrator:Command Prompt"
then you really have admin privileges.

But, for instance, if you didn't disable UAC, and set the VPC shortcut
to run in compatibility mode with the privilege level set to
administrator, then you won't be able to drag and drop. I ran into
this scenario. Not running VPC with admin privileges will allow drag
and drop but can have other effects on your VMs, depending on when
they were created. I have UAC enabled and I am not running VPC as
administrator, this allows me to drag and drop successfully...but I
needed to modify some of the VPC files for my VMs to be able to launch
them again after removing the administrator privilege from VPC.

Clear as mud? ;-)

 

You were right that my command prompt didn't id me as an Administrator.
So, I turned off UAC, rebooted, found that the command prompt now id'ed
me as Admin, fired up my VPC with XP, and discovered that I still
couldn't drag and drop.

 

Not really sure that I did much to help but glad to hear you've got it
working!

 

You told me what I needed to know.

 

I just regained my ability to drag and drop files between guest and host
by uninstalling and then reinstalling the additions, as suggested by
Benjamin Armstrong in response to a question (posted just today)
regarding the same problem as mine.
