Hi guys.
Just wanna share with you guys on this Memory Leak ONLY in Windows 8.
Not sure any of you heard of it or got it before.
I gotten it a few times and finally managed to resolve it.
Apparently this guy below
"Windows Network Data Usage Monitoring Driver" or NDU.sys was introduced in Windows 8.
Info:
Windows Network Data Usage Monitoring Driver - Windows 8 Service - batcmd.com
This guy is pretty naughty and causes memory leak.
It is being reported in a few places below:
Discussion Threads
Non-Paged Pool Leak in Network layer
Windows 8 high memory usage - Windows Discussion & Support - Neowin Forums
Damjan's playground: Windows 8 RTM Memory leak - NDU.SYS?
This screenshot is gotten from Damjan's website
Causes
The exact criteria to trigger is not confirmed 100% though.
Some were pointing at the Network Drivers.
Like what some say, is probably a VERY BADLY written network code by dear Microsoft.
This guy will cause the "Non-paged pool" to grow massively, SQUEEZING almost every last bit of your RAM and also causes your pagefile to be VERY active. Which in turn affects your HDD/SDD IO performance.
The result = causing your system to be slowed down to a crawl, irresponsive
Temporary Solution
Restart the computer.
Alternative (Permanent) Solution
Open up "regedit" and go this key.
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu
Change the "Start" value to 4 (to disable it).
Thanks for reading.
