Amazing again! There was NO mysterious program running in the background that preventing the PC from shutting down!! Speed is between 70-85 Mbps, faster than my Cox plan of 60 Mbps. My PC internet download speed has been stable for the past 6 hours. Amazing!! Intel has an updated driver issued on !! I went through the download, install and reboot. So I googled for the AC8265 driver, found the Intel website. I went through Control Panel -> Device Manager -> Network Adaptor -> Intel Dualīand Wireless -AC8265 -> Right click -> Update Driver ->Search automatically for updated driver -> Windows found the most updated driver is already installed, but suggested there may be better driver on manufacturer's website.

Since I do not have initial internet connection problems, I followed your list of items and went straight to review my WIFI driver. Nothing seemed to consume much to slow down my internet net speed to such extremeĬan someone share some thoughts on this? Any help will be deeply appreciated!! I have watched the Memory and CPU usage for all items running in Task Manager. I have tried anti-virus by Kaspersky, Windows Defender,ĭo anyone know how to find out what is this unidentified program running in the background that slows the internet speed to 0.3Mbps consistently? It is running in the background and preventing the PC from shutting down? Does something inside Windows 10 haveĪnything to do with this? I have turned off 'Allow downloads from Other PCs' in the setting. It takes up almost all my internet bandwidth and choke my internet speed to almost zero. Is running in the background that does not show up on the Task Manager. I believe it is this mysterious program that I have confirmed that it is not due to Cox Internet. This happens at work, at home., during the day, during late night, or 1-5AM in the morning before work. One hour or so due to extremely slow internet speed. So my routine every day is as follows: Start my PC fresh, then restart my PC again every I have to force it to restart and to regain my internet speed back to 60 Mbps. Happens every time that I noticed the extremely slow internet speed and tried to restart. There is no active programs running in the Task Manager. I have closed ALL programs before the restart. When I try to restart, there is ALWAYS a warning saying, 'This program is preventing Windows from shutting down'. I have been fighting this problem for several months after the Fall Creators Update without success: When I start my PC fresh, I get fast internet download speed of 60 Mbps, which is the speed of my Cox Internet plan.
