Windows 7: XP - password req switching to full screen and back

Hi all
Not sure if this is a glitch but I added a password for user USER in XP mode.
Now I get a password prompt every time I switch between full screen an windowed mode -- not really what users would want.

I removed the password again but it still prompts for a password on the switch between full screen and windowed mode. It logs on OK without a password.

Re-installing the VM again fixes this but I shouldn't have to do it.

Bug Nr 1 ?

Everything else so far works fine.

Another question

-- is it possible to make the default USER in the VM machine the same as the user of the host workstation - remembering here that different people could be using these computers -- we have external consultants with "hot desking" facilities.

The "Production" workstations have dedicated connections. The consultants can use laptops etc for accessing Internet, Corporate Intranets, DEV and QA type machines but the PROD network is kept "insulated" with no " open outside" access. (E-sales, CRM,ESS, secure portal etc is of course allowed but via secure servers).


Currently "evaluating" the use of XP mode as opposed to other "Server virtualisation" solutions.
