Yeah sorry should have mentioned that. You need to immediately assign the .ZIP extention to 7ZIP (or alternate) to stop it re-registering that DLL.

You have to un-register the ZIPFLDR dll like this: regsvr32 /u %windir%\system32\zipfldr.dll

Hey, if I buy a retail copy of Vista the license for use belongs to me, not the hardware. Moving and upgrading should be allowed as long as only 1 working copy of the OS exists. I'm sure under UK consumer law these restrictions will not be legally enforcable.

My apologies, I was thinking of this:
