No. It would be too dangerous. I've crashed my op system in the past when trying to install/uninstall Zone Alarm (for example) and need all the edge I can get. As a matter of principle I want all unnecessary processes turned off, no exceptions. The same when I'm flashing firmware where any system slowdown or interruption could kill the device permanently. Before doing so I kill all unnecessary processes with task manager, disable them in services manager, remove them from msconfig so they won't restart when I reboot, remove them from various startup folders and registry run starts, etc. I can usually get it down to 10-15 running processes, just the barebones that windows needs to keep going. It irks me that the avast processes can't be killed, that I must uninstall it completely.
