Hi DonT5:
Thanks for posting about this Win 10 bug. I found your report on the Feedback Hub at https://aka.ms/AAt1rb8 and will leave an upvote and comment there later today.
I have this same issue on my Win 10 Pro v22H2 machine. After I disable the News and Interests widget from my taskbar settings menu (by right-clicking on an empty space in my taskbar and changing News and Interests | Turn Off to ENABLED) and/or Local Group Policy Editor (Computer Configuration | Administrative Templates | News and Interests | Enable News and Interests on the Taskbar | DISABLED) I still see a News and Interests process running in Task Manager. With the News and Interests widget disabled this way my News and Interests process is suspended in Task Manager and consumes no CPU but it continues to consume memory, sometimes using over 60 MB of RAM.

A few users posting about this bug in the 08-Oct-2024 AskWoody topic October Updates Are Out have reported that going to the more extreme measure of uninstalling the MSEdgeWebView2 application (or even uninstalling the MS Edge browser with a custom batch file - see PKCano's 20-Oct-2024 post # 2711510 in that topic) will stop the six instances of MSEdgeWebView2.exe from running under the News and Interests process in Task Manager, but this will NOT stop the instance of SearchApp.exe.
Users posting comments below Vishal Gupta’s 04-Oct-2024 AskVG! troubleshooting guide at Fix: News and Interests Running in Task Manager in Windows 10 have also noted that the WebExperience app described in Step # 5 of those instructions (i.e., STEP 5: Use PowerShell Commands to Uninstall or Remove News and Interests in Windows 10) no longer exists in the current Win 10 OS build 19045.5011, which is further evidence that Microsoft has recently changed the way that New and Interests is implemented in Windows 10.
