Have you ever closed Task Manager only to feel your PC dragging minutes later? 

You’re not imagining it. 

Microsoft’s October 2025 update (KB5067036) quietly broke Task Manager’s close button, leaving behind ghost processes that hog memory and slow down your system. 

If you’re a frequent Task Manager user, or just someone who never shuts down, this bug could be eating up gigabytes of RAM without you knowing.

Feature Explanation

The bug affects Windows 11 users who installed KB5067036, an optional update released on October 28, 2025. 

When you close Task Manager using the “X” button, it doesn’t actually quit. Instead, it lingers in the background. 

Reopening it spawns another instance, and so on. 

Each ghost process uses around 20MB of RAM. 

Multiply that by dozens or hundreds and you’ve got a performance bottleneck.

Have you ever opened a file thinking it was a harmless document, only to realize it was something else entirely?

That tiny “.exe” or “.pdf” at the end of a filename isn’t just decoration. 

It’s the digital equivalent of a food label. 

And yet, Windows 11 hides these extensions by default, leaving users to guess what they’re dealing with. 

For business users, educators, and anyone juggling dozens of files a day, that’s a recipe for confusion or worse, a security risk.
