Microsoft is working on a fix for the Windows 11 update, that will boost performance back up on AMD Ryzen processors. The company notes there's an issue with high L3 cache latency, which reduces gaming performance by up to 15% depending on the AMD Ryzen CPU being used.

In some testing, the folks at TechPowerUp found that the L3 cache latency that normally is at 10ns is at a much higher 31.9ns in the new Windows 11 update on the AMD Ryzen 7 2700X processor. Before the update, the latency was at 17ns... quite the increase.

At the time, the former Apple CEO said that the NeXT operating system was superior to Windows, but Dell founder and current CEO Michael Dell said he told Jobs at the time that it just wasn't going to happen because there was no software for it and "zero customer interest".

Dell talked about Jobs in his new book "Play Nice But Win" where Dell talks about how as a teenager, he was in love with the Apple II. He talks about meeting Jobs and how he asked Dell to license the Mac operating system and use it on Intel-based Dell PCs. In the end, Dell and Apple became competitors and both have enjoyed meteoric rises over the last couple of decades since Jobs asked Dell to put Mac OS on Dell systems powered with Intel processors.

According to Microsoft and technology human rights group Citizen Lab, the hacking group named Candiru has created software that is able to hack into Microsoft Windows to exploit it. Citizen Lab's security researchers showed how the tool has spread around the globe and how it was used to "target various civil society organizations, including a Saudi dissident group and a left-leaning Indonesian news outlet", per Reuters.

Microsoft has already fixed the flaws that Candiru was exploiting. However, Microsoft didn't give Candiru the credit of naming the group directly. Instead, Microsoft said it was an "Israel-based private sector offensive actor" that has been codenamed Sourgum. Microsoft wrote in a blog post, "Sourgum generally sells cyberweapons that enable its customers, often government agencies around the world, to hack into their targets' computers, phones, network infrastructure, and internet-connected devices."

Microsoft issues grave warning for Windows users, update 'immediately'

Jak Connor | Thu, Jul 8 2021 5:32 AM CDT

Microsoft has come out of the gates hot by urging all Windows users to update their operating systems "immediately".

The grave warning from Microsoft has come after a serious security flaw was identified in Windows. The flaw is known as PrintNightmare targets the Windows Print Spooler service, and researchers from the cyber-security company named Sangfor published a how-to guide for hackers to exploit it. Microsoft has said that hackers that exploit this flaw in Windows may be able to install programs on the PC, view/delete the PC's data, and even create new user accounts.

To fix this security flaw, Microsoft has asked all Windows users to perform an update immediately. If you are a Windows 7 user, and you thought this security flaw was just for Windows 10 users - you thought wrong. Microsoft ended support for Windows 7 and has yet still issued an update patching this security flaw. The fact that Microsoft has rolled out an update for an operating system that they officially aren't supporting anymore really highlights the severity of the PrintNightmare security flaw.
