Microsoft Has Rolled Out A New Windows 10 Update To Fix High CPU Usage Bug
Microsoft delivered new cumulative updates to several versions of Windows 10, including the May 2019 Update. The M19U has been plagued with numerous bugs since it rolled out, which according to users included a Cortana/Search issue that caused CPU usage hike.
Microsoft last week finally acknowledged user complaints about the Cortana process SearchUI.exe causing abnormally high CPU usage. To remedy the issue, the company on Tuesday released the September Patch KB4515384, which should get rid of the bug. The release notes read:
"Fixed on Sept 10: Addresses an issue that causes high CPU usage from SearchUI.exe for a small number of users. This issue only occurs on devices that have disabled searching the web using Windows Desktop Search."
Windows 10 users bombarded Microsoft with complaints after it's been found that the KB4512941 update came with several issues. Ironically, that the particular update was intended to fic the lingering bugs found in version 1903.
Microsoft issued a statement promising that the high CPU usage issue will have a fix by mid-September, but kudos to the tech giant, it actually delivered earlier.
The Windows maker also patched some security issues in the operating system along with the bug fix. The new patch should provide extra security against a new class of vulnerabilities known as Microarchitectural Data Sampling.
According to ZDNet, the company has also addressed two zero-days, tracked as CVE-2019-1214 and CVE-2019-1215. They are both are elevation of privilege (EoP) flaws that impact the Windows Common Log File System (CLFS) driver and the ws2ifsl.sys (Winsock) service, respectively.
Lastly, Microsoft has released security updates for some of its programs, including Frameworks, Windows Apps Platform, Internet Explorer, and Microsoft Edge.
In April, Microsoft promised to up its game but last month alone we've seen Windows 10 1903 updates run aground and updates break Bluetooth connections. Last month, the company also acknowledged the presence of vulnerabilities in all versions of Windows 10. There had been two Steam exploits that were capable of compromising the security of the OS.
Since the Microsoft Windows 10 update does not happen automatically, users may refuse the update prompt that appears on their device. Users who have already installed the update may also undo the process and free their devices up from the trouble of orange and red screen simply uninstalling the latest update.
The latest update -- KB4515384 - Build 18362.356 -- can be installed manually through the Microsoft Update Catalog website or via Windows Update.
