I have noticed over the past few days something odd was happening to my almost brand new pc since these windows updates and it took a lot of time and reading to figure this out. I will take no credit for this as this was someone else's ideas and how they fixed it, but i will say thanks to this guide it also fixed my problem. See below for the full how to guide. Step 1 Use the charms bar on the right hand side and go to search and type regedit. Step 2 Navitgate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\NDU Step 3 Where it says Start on the right panel right click it and select modify and change the value data to 4, click ok then restart the PC. By doing this myself i went from 97% ram used to a nice 15%- 18% with minor apps running and games running at about 30%. After disabling Ndu.sys (Windows Network Data Usage Monitoring Driver) with regedit and performing normal boot - voila memory leak has gone!!!! UPDATE: After more reading this problem is to do with Qualcomm Killer e2200 Network So as far as i know if your using Any of the MSI Gaming G mother boards and possibly the ASrock Faitality series boards you could have having the same problems as i have. Hope this helps.
