I used to demote my user account so that it had no admin priveleges and used a 'sudo-like' trick where you create a shortcut to IE6 and enabled the 'Run with different credentials' option to open a shell window as local admin so I could install, uninstall things etc.
When I upgraded to IE7 this stopped working - IE7 launches Windows Explorer separately.
I've tried running Windows Explorer with different credential but this does not work.
Does anyone know how to re-enable this behaviour so that I don't have to run my computer on a daily basis with administrator priveleges?
