A recent Windows 11 update has caused Task Manager to misbehave. Closing it doesn’t fully shut it down, resulting in multiple instances running simultaneously and potentially affecting system performance.
Task Manager not closing properly
Multiple instances can run simultaneously
Each instance consumes system RAM
Performance impact may go unnoticed
Frequent reopening leads to bloat
Battery life could be affected
So, what’s happening? Users are finding that the Task Manager keeps running even after they try to close it. Each time you open it, a new copy keeps cranking up in the background, which can pile up quickly.
Task Manager’s Strange Behavior
When users close Task Manager, they expect it to shut down. However, after a Windows update, it seems like closing the window doesn’t actually stop the program. This glitch causes every new Task Manager launch to add another layer on top of the old process.
You’d think a few extra copies wouldn’t matter too much. Each instance eats up around 20MB of RAM and only uses about 0-2% of your CPU. For most people, this might fly under the radar, especially if you’re not running a ton of programs. But if you often rely on Task Manager and open multiple copies, the slow but steady drain on resources can start to add up.
Potential Impacts on Performance
As you accumulate multiple versions of Task Manager, you might start to notice a performance hit, especially if your computer tends to stay on for long periods without a reboot.
Imagine having two or three dozen copies running at once; it’s like packing your room too tight—eventually, you’re going to feel cramped. This can be especially concerning for laptops, as it could harm your battery life as well.
