I desperately need a new high end machine for my motion graphics work and can't wait till 'sometime 2013' so I'm going ahead with my windows workstation build. I've been a Mac owner exclusively for 15 years. I've used PCs on the job and even field some minor windows based tech support calls from clients occasionally, but have never personally owned a windows box before. I'm looking for some advice on the windows experience from fellow Mac users who've made the switch due to the lack of a clear direction for the Mac pro. I'm primarily curious about a couple of things: Firstly, I know very little about standard antivirus procedures. I'm aware that there are a million competing products out there and a few popular leaders. Are they all based on the same principles of downloading the program and then downloading daily updates? I've noticed they all seem to cause a lot of false positives, particularly during on demand file scans on file types that don't have clear associations. Is this just par for the course? Is there a clear leader in this department, kaspersky, avg, norton, ect. ? Or are there better solutions than these popular consumer choices? Secondly, how long has it taken you to lock down and customize your windows system the way you like? One thing I love about OSx is the centralized system preferences pane. I hate how windows scatters these panels in various places around the system. Sometimes I feel it's like playing one of those 'whack-the-gopher' games. I have one client whose dell systems keep disabling their wireless card despite having completely uninstalled third party controllers and competing resources. The place it gets disabled from changes between three different locations. It's things like this that annoy me, and I'm curious what some of your experiences have been like with 'locking your system down'. And thirdly, as far as customization goes, do most of you just strip Windows down to its essentials? Do you use themes to enhance or simplify the look/feel of the environment? Third party apps, etc? Any and all advice, experience, tips, caveats, etc. are much appreciated!
