After upgrading to Windows 11, many people will encounter hardware or software incompatibility issues. These problems may affect the user experience and may even cause the system to fail to function properly. If you are considering upgrading, or have encountered problems after upgrading, the following information can help you quickly judge and respond.

The processor does not support TPM 2.0

Windows 11 has clear hardware requirements, the most important point is that the processor must support TPM 2.0 (trusted platform module). Many 8th generation or earlier Intel processors, although performing sufficiently, do not have built-in TPM support.

• If your computer does not support TPM 2.0, you will receive a warning when upgrading, and the installer may directly prevent you from continuing.
• Some motherboards support turning on the TPM function in the BIOS. You can enter the BIOS to see if there are any relevant settings on the "Security" or "Advanced" tab.
• If the motherboard supports it but is turned off by default, remember to manually turn it on before trying to install it.

It is recommended to use Microsoft's official "PC Health Check" tool to check whether it meets the requirements before upgrading.

Driver incompatible

After the upgrade, some hardware drivers may not work properly, especially older models of graphics, sound cards or network cards. Common manifestations include:

• Unstable network connection or unavailable to connect to the internet
• Screen resolution abnormal
• Sound cannot be output

Solution:

• Go to Device Manager to see if there is a yellow exclamation mark
• Download the latest Windows 11 drivers to the official website of the motherboard or laptop brand
• Use third-party driver management software (such as driver life and driver elves) to automatically detect and update

Some brands (such as Dell and Lenovo) have begun to push drivers specifically adapted to Windows 11, and it is safer to give priority to using brand official website resources.

Old software runs abnormally

Some old software, especially internally developed programs, old versions of antivirus software or industry-specific tools, may experience compatibility issues on Windows 11. Common phenomena include:

• The program crashes or cannot be opened
• The interface displays abnormality
• The function cannot be used normally

You can try the following:

• Right-click the program icon and select "Properties" → "Compatibility" → Try running in Windows 10 or Windows 8 mode
• Run the program as an administrator
• Update the software to the latest version, and many developers have launched updates that are compatible with Windows 11

If the software is very important but does not work, it is recommended to contact the developer or manufacturer for support.

Bypass tips during installation (use with caution)

If your computer does not meet the official requirements but wants to force Windows 11, you can bypass the restrictions by:

• Use a USB flash drive to create installation media, skip the system check to install it directly
• Modify the registry or use third-party tools to bypass TPM checks

But be aware:

• Microsoft does not recommend this, as future updates may lead to system instability
• Some features (such as BitLocker encryption) may not work
• Officials may not provide support after a problem occurs

In general, Windows 11 compatibility issues are mainly focused on hardware support and old software operation. As long as you check the equipment configuration and commonly used software in advance, most problems can be avoided in advance. Basically, these things you need to pay attention to. Making more preparations before upgrading can save a lot of trouble.
