Microsoft recently released Windows 11 optional update KB5067036, which brings a series of functional improvements, including a new Start menu and improved power options.Microsoft says the update also fixes an issue where the Task Manager might not correctly group applications with their processes, but it appears the fix has introduced a new issue.
Windows Latest found thatOn affected PCs, when users try to click the "X" close button of the Task Manager window, it does not actually exit and the process continues to run in the background.
When the user opens and closes Task Manager again, a new Task Manager process will be left in the background, causing the number of processes to accumulate.
Windows Latest stated that the probability of this bug appearing is not low. In their test of 100 virtual machines, about 30% of the machines were affected.
It also conducted "extreme tests",Opening and closing the Task Manager about 100 times continuously resulted in 100 Task Manager processes running in the background, each taking up about 20–25MB of memory.
For high-end PCs with large memory, the impact is minimal, but for low-end hardware with less memory, the extra consumption may cause performance bottlenecks and system lags. Of course, in actual use, the vast majority of users will not open the Task Manager a hundred times a day.
