How about all my CPU cycles?

Updated Some Windows 10 users are experiencing alarming CPU spikes after the last optional cumulative update of the week.

The problem patch, KB4512941, was released last week as an update for Windows 10 1903 (also known as the May 2019 release).

Although optional and not a security update, 1903 remained an important patch and contained a lot of fixes, including the treatment of a problem that prevented some applications created with VB6 running, as well as VBA Macros and applications that used VBScript

We can imagine that the Windows team dusted off and then went for what it did. I felt it was a well-deserved Labor Day weekend (at least in the US) At the time of writing this article, the patch support page states with sufficient air "Microsoft is not aware of any problem with this update. "

Oh dear

It became clear over the weekend that the patch has resulted in an impressively high CPU usage for some of the users who pressed the button & # 39; Check for updates & # 39; And they installed the thing.

The problem, according to frustrated users on Twitter, Reddit and Microsoft The own comment forums seem to be with Cortana, which is absorbing about 40 percent or more of the CPU in the affected systems. We assume that this is a way to make users notice.

Call Windows 10 what you want – Microsoft seems


Some Players have reported a precipitous drop in frame rates after the update. Those who can uninstall the decrypted code saw that performance was restored.

The problem does not seem to be too widespread today, and Microsoft clearly does not consider it important enough to update the support page. We contact the Windows giant for more information and we will update it if there is an explanation.

It's all a bit embarrassing. Detectives in Windows Latest discovered that the problem was also reported in the Microsoft Feedback Hub for the Windows Insider Preview Ring, but no action was taken before the update was released worldwide.

No doubt, no one could find out what Windows 10 compilation those Insiders were really testing. ®

Updated to add

Redmond has not answered our questions, but at least he seems to be acknowledging that there is a problem with the update.
