Windows 10, with the latest update PCs are slower

With the latest Windows 10 update, an increase in CPU consumption has been reported: the problem is Cortana. Here's how to fix it.

Microsoft has recently released Windows 10 update KB4512941. This is not a big update, but a simple update that goes to fix some bugs and improves the use of some features of the operating system. For example Windows Sandbox and the "Remote Desktop Connection" that shows black screen when you try to use it. The update that has just been released and that can be downloaded and installed via Windows Update has, however, some problems. At least that's what the first users who have installed it report.

The first reports were published on Reddit, a forum widely used in the United States, and in a short time the comments were dozens and dozens. All users reported the same problem: an increase in CPU usage and a decrease in computer performance. Analyzing the tab of the "Task Manager", some experts have found the cause of the problem: the culprit is Cortana, the assistant present on all Windows PCs. In fact, with the Windows 10 update Microsoft has released a faulty version of Cortana, which in addition to increasing CPU consumption does not even show search results.

Windows 10 update: the problem is Cortana

A Microsoft error. This could be the cause of Windows 10 slowdowns encountered by many users who have installed the latest update. Inside the update would be a corrupted version of Cortana that requires more consumption of the PC's CPU. Analyzing the Activity Manager, the cause of the problem is SearchUI.exe that causes a 30-40% increase in processor consumption compared to before.

On Microsoft's official forum, there are many users complaining about the problem: some have found an increase in memory of 150MB. Resulting in a slowdown on the part of the PC. This, however, would not be the only malfunction found by users. Cortana, in addition to putting stress on your PC, doesn't work. If you try to do some research from the "hole" in the Windows 10 Start menu, it doesn't return any results.

After user reports, Microsoft would be working to release a new update soon that will fix the problem.

How to fix the problem

If you don't want to wait for the update to arrive from Microsoft, you can fix the problem yourself by uninstalling the problematic update.

To do this you need to go into the Control Panel and then into the Update and Security section.
