Windows 7 - Internet Explorer - Multiple instances of same version -

i have been hired work multiple clients once using ie on windows 7. want ask if there way run multiple ie's @ once packed several tabs each individually divided across them.

i run each ie separated unit each client working with. 1 ie instance have client stuff , second client b etc.

i click instances on task bar load each browser config match current client.

edit: clarify doing customer service gives me different tools different services. organize them in different ie windows.

one way using virtual machines each ie instance - way "real" of ie possible.

microsoft has vms available versions of ie 8+ , windows 7+: https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/windows/
