Every process started by Windows (with the exception of the System "process") runs in user mode.
I have seen many times some application such as browser whenever i opened it on my computer after some time it get crashed and rebooted system.
if every process other than system process run in user mode, that application process should not affect whole system.? is there any possible reason why it affect whole system?
e.g e.g. browser is one application which runs in User mode but i have seen many time as soon as i opened browser my system either rebooted or hanged and crashed if process runs in user mode why it affect my system(MTA 98-349 (Understanding Operating system architecture))
