I'm running Windows 8.1 in Parallels 9.0.23350 on Mac OS X 10.9 (13A603) The Mac has 16 Gb of RAM (4 allocated to Win 8.1 with 2 CPUs). Windows is used to run MS Office. It's slow. While Outlook uses 100Mb of ram, the only process using the processor constantly is prl_cc.exe. It averages 53%. What is this process and why is it eating so many resources (currently 38 threads and 51%)
