Best way to run multiple instances of Win7?

I on a daily basis run a program that use's the "web browser" control. Let's just say I need to constantly check 3 hotmail accounts (24-7), all with their own cookies etc.

So far, the only solution I've found is to create new user accounts under win7 & run 1 instance of the hotmail program on each username. Thus, keeping the cookies etc. seperate from each other & allowing me to login 3 accounts at once. By having 3 user accounts setup.

Please tell me there is an easier (less ram intensive) way to emulate seperate instances of the win7 operating system??

Thanks! :major

 

How about checking your 3 mail accounts with an email client like Outlook or Thunderbird? Then you won't need 3 user accounts or 3 Windows instances.

 

It's complicated, but that's not a possibility at the moment.

Any other suggestions?

Someone mentioned virtual machine to me....would that work to run 10+ instances of a win7 desktop?

My PC is a Quad Core AMD running at 3.4ghz each. I've got 4gb of RAM etc. & I have dual harddrives.

 

Tried different browsers for each address, like ie for one firefox for one, chrome for the last?
