The latest Windows 11 releases, versions 24H2 and 25H2, have a very bizarre bug (http://www.windows11newsinfo.com/smf/index.php?topic=42866.0), where closing Task Manager does not close its process properly, and every other launch results in duplicate processes piling up and eating your system's resources. Right now, there are no official fixes, except for a temporary workaround, where Microsoft recommends users kill duplicated processes with the taskkill.exe /im taskmgr.exe /f command executed as Administrator. However, enthusiasts have already discovered a way to resolve the issue.
You can prevent Task Manager from spawning duplicated processes by adding several registry keys or enabling two IDs using the ViVeTool app:
1️⃣ Download ViVeTool from GitHub (http://github.com/thebookisclosed/ViVe/releases) and unpack the files in any folder you like.
2️⃣ Launch Command Prompt as Administrator and go to the ViVeTool folder using the CD command. For example, CD C:\vive.
3️⃣ Type vivetool /enable /id:49407484,57048231 and press Enter.
4️⃣ Restart your computer.
After this, Task Manager should no longer duplicate itself every time you launch it.
Another way to patch the buggy Task Manager is to add four keys to the system registry, as explained by SimonMacer on GitHub. You can simply download the ready-to-use file from GitHub (http://github.com/SimonMacer/CreateMediaRefresh25H2/blob/main/Other/Resolve%20Task%20Manager%20process%20might%20continue%20to%20run%20in%20background%20after%20app%20is%20closed.reg) (the file's content and the keys it adds are visible on GitHub, so you can be sure the file is not doing any shady stuff with your PC's registry) and launch it to apply changes. Tip: You can always check what a registry file does by opening it in Notepad and checking paths, keys, values, and their data.
Should you need to undo those changes, launch Command Prompt as Administrator and type the following:
REG DELETE "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\FeatureManagement\Overrides\14" /f
While applying either of these methods should not cause any damage to your system, we still recommend backing up important data. Also, if you are not comfortable with editing the system registry or using the ViVeTool app, you can wait for an official fix from Microsoft. Meanwhile, you can clear duplicate Task Manager processes by restarting your system or using the taskkill command mentioned above.
