Windows 11 is officially out, and early adopters are already reporting some bugs and issues with the next generation of Windows. 

While many of these issues should get sorted out pretty quickly by Microsoft, if you encounter one it doesn't matter how soon a fix might come — you want to know what's going wrong with your PC, and how to deal with it.

To help you solve your Windows 11 woes, we've pulled together this guide to the most common Windows 11 problems we're seeing right now, and what (if anything) can be done about them.

Microsoft won't let you upgrade to Windows 11

Even though Windows 11 launched October 5, that doesn't mean you'll have an easy time installing it. Microsoft has set some pretty steep Windows 11 system requirements, and if your PC doesn't meet them you'll hit a wall when trying to install Windows 11 or upgrade to it from Windows 10. Here's what you need:

  • CPU: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)
  • RAM: 4GB
  • Storage: 64GB of larger
  • System firmware: UEFI, Secure Boot capable
  • TPM: Trusted Platform Module (TPM) version 2.0
  • Graphics card: Compatible with DirectX 12 or later with WDDM 2.0 driver
  • Display: High definition (720p) display that is greater than 9” diagonally, 8 bits per color channel
  • Internet: Windows 11 Home edition requires internet connectivity and a Microsoft account to complete device setup on first use.

There are a number of different ways this issue can impede you. To solve the problem, the first thing to do is verify that the PC you want to install Windows 11 on meets the minimum requirements. The fastest way is to download Microsoft's PC Health Check app from the Windows 11 website (the link to "download PC Health Check app" is at the bottom of the page) and run it. The PC Health Check app will then tell you whether your PC meets the minimum requirements to install Windows 11, and what needs to be fixed in order to meet them.

If your PC doesn't meet the Windows 11 system requirements: Windows 11 won't install unless your PC meets the minimum requirements, and some are more onerous than others. The most restrictive requirements are those which demand your PC have a pretty modern CPU and TPM 2.0 (Trusted Platform Module) support. 

This is ostensibly so Windows 11 will be more secure. And if you have a PC built within the last 5-10 years, there's a chance that even if you don't have TPM 2.0 enabled, you can switch it on in your BIOS. To find out, just reboot your PC, open your BIOS menu, and hunt around to see if there's a setting to enable TPM. If you can enable it, that might let you install Windows 11 with no trouble.

However, it's quite possible to run Windows 11 on a PC that doesn't meet all the minimum requirements. If you do a clean install of Windows 11 using an ISO file, you will often have the option to proceed with installing Windows 11 even though your system is non-compliant -- you'll simply get a warning that it may cause you to not receive important Windows 11 updates, and may cause damage to your PC (very unlikely).

If you try to install Windows 11 but can't because you're lacking an appropriately modern CPU or TPM 2.0, there's a couple ways you can try to get around the issue. First, you could try to upgrade to Windows 11 without a TPM using this script trick, which basically fools the Windows 11 installer into letting you proceed. 

You can also try to bypass Windows 11's ridiculous system requirements with this hack directly from Microsoft. It can be a little dicey since you have to edit your Windows registry, but it comes directly from Microsoft and is listed on their public support page, so it should be pretty safe. When in doubt, back up your PC and important files before trying!

Your PC meets the Windows 11 minimum system requirements: If your PC meets the Windows 11 minimum system requirements and passes the PC Health Check with flying colors, that still doesn't mean Microsoft will let you upgrade to Windows 11.

Windows 11 is a free upgrade for Windows 10 owners, but the offers to upgrade are rolling out gradually through mid-2022. Newer, more compliant PCs should get priority, and if you're running Windows 10 you should get your offer to upgrade through Windows Update -- but it may not come for months yet. 

If you can't wait, you can try doing a clean install of Windows 11 using an ISO file on your PC. You could also run out and buy a new PC with Windows 11 pre-installed, but that seems like a pricey solution.

Windows 11 hurting performance of AMD CPUs

AMD and Microsoft are currently working on fixes for two common Windows 11 issues that can slow some AMD processors by up to 15%. The first is that Windows 11 may cause L3 cache latency to as much as triple on some AMD PCs, and the second is that an AMD CPU feature which preferentially allocates work to the CPU's fastest core may not work correctly in Windows 11.

What's worse, Microsoft released a cumulative update the week after Windows 11 launched that actually appeared to make AMD performance even slower. Both AMD and Microsoft have since promised to patch the issue before the end of October.

If you think you might be affected by this issue, there's not much you can do except wait for Microsoft and AMD to release software updates that address it. So if you have an AMD CPU in your PC, you might want to hold off on updating until after October 2021.

Windows 11 causing Internet slowdown

Microsoft is reporting some compatibility issues between Windows 11 and some Intel networking software that may cause early adopters to experience some Internet issues.

According to Microsoft, some Intel "Killer" and "SmartByte" networking software is not playing nicely with Windows 11. This can cause Windows 11 PCs with said software to experience decreased Internet performance, most notably slower loading of websites and videos. 

As with the AMD issues, if you think you might have this problem there's not much we can recommend here beyond waiting for Microsoft to patch the issue. Luckily, the company's Windows 11 known issues page claims they should have a solution ready to go by October 12th.

Windows 11 still has Windows 10 Start menu

Some folks who beta-tested Windows 11 before it was released report that they have a problem with still seeing the Windows 10 Start menu and taskbar despite having upgraded.

If this happens to you, don't worry: it appears to be a simple fix. All you need to do is uninstall a Windows update by navigating to Control Panel > Programs > Programs and Features > Installed Updates.

Then, select update KB5004300 and uninstall it, then reboot your PC -- you should hopefully have a working Windows 10 Start menu and taskbar. Now, head to Windows Update and reinstall the update you deleted -- in this case, KB5004300 -- and you should be back to a fully functioning Windows 11.

Do note that this can be done with relative safety, so if deleting and reinstalling KB5004300 doesn't work, you can try the same trick with other Windows updates to see if it fixes the issue on your PC.

Windows 11 Start menu won't let you type

As with any new software there's bound to be some visual bugs and oddities cropping up in Windows 11, but many users are reportedly seeing one issue in particular: sometimes when they hit the Start button to bring up the new (centered) Start menu, Windows 11 won't register any keyboard input. That's a problem for people who like to use the Start menu's built-in search feature, and it can seriously slow down your workflow.

Luckily, Microsoft's suggested workaround is simple: if you find your Start menu won't register anything you type, Microsoft recommends you open the Run app. Typically you'd do this by hitting the Start button and typing run, but given the nature of this bug you should try the keyboard shortcut to launch Run: Windows key + R

Once you open the Run app, you should be able to close it without doing anything and your Start menu should return to normal working order. It's yet unclear when we should expect Microsoft to roll out a fix for this bug, but since the solution is pretty simple it shouldn't slow you down too much.

    I found that the Verge had an article about editing the registry to make it easy to upgrade a non-supported computer. I had no issue upgrading a Surface Book 2 with a non-supported CPU following their instructions. See them here: How to install windows 11 unsupported cpu

    Does anybody know if the new patch fixed the video driver lag issue? This is where you get a noticeable (2 sec?) lag when trying to use the mouse on the screen. This is not a good situation in a fast-paced video game.

    The solution to the problem is to remove all video drivers and install the windows default. I've got no more lag, but two hirez monitors that show text at 640x480 resolution :(
