Well, here's how I see it...
The 'problem' is... since Win9x... users became accustomed to running Windows in admin mode - even in Enterprise (corporate) environments. Apps were written with this in mind - developed in admin mode - and tested in admin mode. User mode was an afterthought, if at all.
In home environments, pre-Vista, even 4 year-olds had full-blown admin rights - able to install anything they want, go anywhere they want on the web, yada, yada, yada.
In the past, Microsoft (wrongly) assumed 99% of the time, ppl were going to run in user mode, and 1% of the time in admin mode but, they supposedly 'discovered' ppl were actually running in admin mode 90% of the time and user mode 10% of the time - even though XP, for instance, remains in admin mode after installation. Hello?!?!?!
That being said...
Microsoft et al (after listening to security complaints for years) has decided enough-is-enough, and starting with Windows Vista - and from here on out - all users in the Windows ecosystem WILL be running in user mode - period. Exclamation!
I *think* the specific problem you're having is... you're used to doing things old skool style (as we all were) in admin mode - using legacy apps that aren't Vista-ready, yada, yada, yada. Now, Vista is forcing you to NOT run in admin mode, by design, and you're getting frustrated.
If I'm understanding your situation correctly (and I'm probably not) your choices
might be to revert to an old skool OS, like XP, but I think I would try a format/clean install first... albeit an old skool solution! It's hard to break old habits, yes?
