Unusual notification problem on Windows 10 Issue with pings or alerts not functioning properly
Hey, I see something odd here. You might want to try this with me. It becomes more obvious when using AMD's 3000 series CPU. - Connect directly to your router - don’t run other programs on your PC. Open the command prompt (press Start > type "cmd"). Type "ping <your local router IP> -t" unless you have a complicated network or powerline setup, then it should be under 1ms. While pinging, launch a game or application. You don’t need to join any server—just open the main menu of the game. Notice a sudden increase in ping.

Those who don’t see the issue consistently are using Windows 1909. The rest are running Windows 2004 or 20H2. I’ve checked my router, cables, ports, drivers… etc. Plus others are facing the same problem as me (the six international participants). I’m pretty sure it’s not a hardware problem. In Windows XP, 7, this issue doesn’t appear. Someone also mentioned that Windows 10 might now include processing delay in ping. Not entirely sure.
This problem didn’t occur on my older Windows XP PC, though I suspect the latest updates might be the cause.
It appears to run on Windows 2004 or 20H2 and is impacted by non-network dependent programs such as AMD Ryzen Master. Opening it directly triggers a significant increase in activity.
I just tested it on my computer and it happens too. Probably similar to what @flashiling mentioned—starting a game causes the system to briefly slow down (temporarily uses a lot of CPU) and slightly delays the pings. Or maybe the game you and I started has heavy network connections right from the beginning, which affects the packet timing a bit. We're only talking about a few milliseconds for a couple of packets, which isn't noticeable at all.
I really can't recall this occurring on Windows 7 or XP with an older PC, to be honest. Thanks for your feedback!
I believe I identified the reason; it was released on February 9, 2021 - KB4601050 Cumulative Update for .NET Framework 3.5 and 4.8 targeting Windows 10, version 2004, Windows Server 2004, Windows 10 20H2, and Windows Server 2004 20H2. This update follows the one released after uninstalling it on January 12, 2021 - KB4586876 Cumulative Update Preview for the same versions. Installing it on another machine triggered the spike. Removing it resolved my problem. An update (KB4578968) also seems to impact this and appears after KB4586876.
For those curious, the latest cumulative update appears to resolve this problem, and the ping issue is now quite minor.
