An increasing number of Windows 11 users have reported that their computers are struggling with slowdowns and freezes after installing the first cumulative update to the new operating system, particularly those who own AMD processors. While Microsoft has not officially acknowledged this issue, users on reddit and Microsoft’s support forums have been posting concerns about the issue since early last week. An increasing number of Windows 11 users have reported that their computers are struggling with slowdowns and freezes after installing the first cumulative update to the new operating system, particularly those who own AMD processors. Windows 11’s First Cumulative Update Makes AMD CPU Issues Worse
PSA: DO NOT UPDATE YOUR LAPTOP TO WINDOWS 10

If you’re using a laptop that has an AMD processor, upgrading to Windows 10 can cause some serious issues. If you haven’t installed it yet and own a laptop with an AMD processor, DO NOT INSTALL WINDOWS 10. You will experience some performance issues with web browsing after upgrading to Windows 10. Microsoft is aware of these problems and working on a fix for it. For now, just avoid installing Windows 10 on your computer if you use an AMD processor on your laptop or desktop computer…or at least update as a last resort.
What is causing the problem?
This issue appears to be caused by a security feature that Microsoft added to prevent Meltdown and Spectre hacks from being used on Windows machines. This function is enabled by default, and prevents all programs (including malware and antivirus software) from reading certain areas of memory. However, Microsoft has confirmed that AMD chipsets do not correctly follow our instruction when it comes to interpreting its new security protection, which is designed to prevent possible attacks against Intel processors using flaws discovered in January 2018. When these systems are paired with AMD-based GPUs, they can result in an infinite loop of reboots that render computers unusable—which seems exactly like what happened in some cases.

What will Microsoft do to fix this?
Microsoft is aware of these issues and are actively working on a solution. It’s likely that an upcoming update will address at least some of these problems. However, in general, people with AMD CPUs should avoid Windows 11 until all of their issues have been fixed. The updates released to date seem to make things worse—and you might end up losing your data while waiting for Microsoft to finish working out all of kinks.
How can you fix it?
Windows 10 has long been considered to be a more performant and efficient operating system than Windows 7 or 8, but since its release there have been some issues with computer systems. Namely, most of these issues have involved problems with Internet Explorer, but lately many users have been reporting serious difficulties when trying to run their programs. The cause seems to be an issue with all current processors manufactured by Advanced Micro Devices (AMD), particularly those in laptops. While initially it was just performance issues, many users are now finding that after applying Microsoft’s latest cumulative update (KB3081424) they can no longer get any programs to launch at all.
A Complete Guide to Downgrade from Windows 10 back to 7 or 8.1
You might not be happy with Windows 10, or you might just feel comfortable with an older version of Windows. Whatever your reason for ditching Windows 10 in favor of a previous version, it’s important to know exactly how to downgrade. The following guide will show you how to downgrade from Windows 10 back to 7 or 8.1—and beyond. But before we get started, let’s take a look at why anyone would want to downgrade their system in the first place. Downgrading offers several benefits, including faster boot times and more privacy controls.
#Downdetector on Twitter
Earlier today, Microsoft released its first cumulative update for Windows 11. The software giant has been on a mission to keep its latest operating system stable, and so far that’s been relatively successful—but yesterday’s cumulative update caused more problems than usual. Users who installed KB3184143 reported widespread issues with their machines. Just looking at Downdetector, one of our favorite places to check when troubleshooting issues in Windows, you can see how widespread these problems were—and there was no particular pattern to them.
Does Windows 11 affect AMD?
As noted by Forbes and ExtremeTech, updates to Windows 10 may have made performance on computers with AMD chips worse. But why is that? Because Microsoft uses a specific version of software in Windows 10—the User Mode Scheduler (UMS)—on their newest operating system to help manage tasks for background processes. Older versions of Windows use a different kind of scheduler, which doesn’t cause those same problems. This isn’t an issue that only exists in Windows 10; it was also in existence previously but not as obvious.

Did Windows 11 fix the AMD problem?
It would appear not, at least if you are running certain AMD processors. After last week’s Windows 11 release, I was seeing some users reporting that their PCs were running sluggishly after installing the update. One of our readers with an Intel i7-6700K Skylake processor and an MSI X99A motherboard said that his PC used to boot in under two minutes but now takes between 6 and 8 minutes. It appears that there is a fix for it though, according to Microsoft.
Does Windows 11 cause performance issues?
Windows 11 has faced its fair share of issues, from privacy concerns to problems with outdated software. However, Windows 11 users may have a new reason to be frustrated with Microsoft’s latest operating system. The first cumulative update for Windows 11 has reportedly introduced some serious performance issues with older computers and laptops. Reports indicate that devices running Windows 7 or 10 see a 10% decrease in overall performance after installing April 2019 Update, while devices running Windows 8 or 8.1 are hit even harder with an estimated 15% decrease in performance. For devices already struggling to run older versions of Windows efficiently, these numbers aren’t just alarming—they’re heartbreaking.
Is Windows 11 stable now for Ryzen?
This is a tricky question and one I get asked on a daily basis. The simple answer to your question is, it depends. While Windows 10 has been fairly stable since its launch in July 2015, that doesn’t necessarily mean that Windows 11 will be. Unfortunately, there is no crystal ball I can look into and tell you what will happen when Microsoft finally releases it. My biggest concern right now is with Skylake users, who are reporting stability issues after installing cumulative update KB4103718. If you have been holding off upgrading because of Ryzen issues in Windows 10, I would still recommend waiting for Intel to release their own fix for Skylake before jumping onto Windows 11.
Does Windows 11 support Ryzen?
It’s no secret that Windows 10 has been less than friendly to AMD’s Ryzen platform. Since its release last year, Windows 10 updates have been worse than Linux for Ryzen users, which is sad considering how long it took Microsoft to support Zen in their flagship OS. To be fair, Microsoft has made progress since then and some of those early bugs were fixed with a recent Windows update. Still, it looks like things are about to get worse for Ryzen fans: A new cumulative update issued by Microsoft today seems to make matters worse on at least one AMD CPU.
