But if I leave qBit turned on for about 8 hrs or more, the RAM leaking will crash Parsec. And I'll lose my control to it, until I told my parents to reboot it.
One day I came up with an idea that "maybe virtualize something will solve this problem", so I turned on "UAC virtualize" in Task Manager after qBit started. (Although later I realized it might not working at all)
However, things were surprisingly well - the AIO kept running for about 2 days with qBit never turned off, RAM usage is totally okay, and most important - Parsec still working, without crashing!
SO, if U guys suffering RAM leaking, please try this method, please reply whether it works or not!
