I also have a general purpose computer and a Vue dedicated computer (plus companion software, like Geocontrol, Poser, etc). This allows me to go easy on protection software on the Vue computer (firewall, antivirus, antispyware) and make it absolutely minimal.

In addition, I almost never change anything in the Vue computer, unless something is broken. For example, I don't update drivers and I don't install hotfixes unless I'm faced with a Vue problem that needs it (which is practically never).

Also, I removed all non-vital services, all widgets, etc, and simplified the Windows GUI, optimizing it to performance to the maximum.

My Vue computer is an extremely stable environment, fast and reliable.
