Hi, I have searched the forum and found various references related high CPU load and the prl_cc.exe. I have the situation under Windows Vista as well. Even so the system is doing nothing prl_cc.exe is causing a CPU load of 30-50%. This causes the host system to be slow and as well the guest system to behave strange. Is there anything new related this issue or is that still unresolved yet? Thanks for an update Alex -- considering to go back to Parallels 3 because this just worked so much easier and much more performat
prl_cc at 99% CPU even after 3810 I upgrade to 3810, and despite this prl_cc.exe still occupies one core at 99% and Windows XP is unusable. The only respite is to kill the prl_cc.exe process in this task manager, immediately after every reboot David
