I have always installed some of the Windows Live Essentials programs and have never had any issues with the install been running Windows 8 Pro on my Laptop with dual SSD's for many months with no more issues than 2-3 and most were my mistakes. I am getting ready to do the install on my desktop but am doing a clean install after running the Windows 8 upgrade advisor and it found to many issues with software for me so , I am doing a clean install. I was being help back on doing the Desktop because of no Media Center until it was offer for free. Once you learn the short cuts to Windows 8 etc and read some of the MS info on the internal working of 8 it becomes a much better user experience as far as I am concerned. Love the OS.
