what is compatibility mode

The function of compatibility mode is to enable old Windows programs to run normally in the new system. It solves software compatibility issues by simulating the old system environment and is suitable for old games, internal management systems and unupdated professional tools. How to enable: Right-click Program Properties → Switch Compatibility tab → Check and select the appropriate version → Apply settings. It is recommended to give priority to trying Windows 7 or XP SP3, and to improve success rate with administrator privileges. However, it should be noted that the compatibility mode is not universal, may affect graphics performance and is only a temporary solution. Updates or alternative software should be considered in the long run.

Compatibility Mode is a practical feature in Windows systems, which allows you to start certain programs in the way older versions of the system run. This is especially useful when you use some older software that doesn't work properly on new systems.

Why do I need compatibility mode?

Many users will encounter this problem: a program that once runs well on old versions of Windows (such as XP or Win7) suddenly cannot be turned on, crashes or has abnormal functions after upgrading to Win10 or Win11. At this time, the compatibility mode can come in handy. It simulates the environment of the old system, making the program mistakenly think that it is still in a "familiar environment", thereby restoring normal operation.

Common situations include:

• Some old games crash if they fail to full screen or start
• The old management system developed internally is not compatible with the new system
• Some professional tool software does not update to support the latest Windows version

How to enable compatibility mode?

The operation is actually very simple, and it only takes a few steps to set it up:

1. Right-click the program icon you want to run (usually a .exe file)
2. Select "Properties"
3. Switch to the Compatibility tab
4. Check "Run this program in compatible mode"
5. Select the appropriate version of Windows (such as Windows 7, Windows XP, etc.)
6. Click "Apply" and try to run the program

If you are not sure which version to choose, you can try Windows 7 or Windows XP SP3 first, these two are the most frequently selected compatibility targets.

In addition, you can also check "Run as administrator". Some old programs have high permission requirements, and this option can improve the success rate.

What should I pay attention to when using compatibility mode?

Although the compatibility mode is very useful, there are some things to note:

• It is not omnipotent, and some programs may not run normally even if they are used.
• If the program relies on specific drivers or system components, there may still be problems
• Graphic interface or performance may be affected, such as abnormal resolution display or lag in operation
• Each run requires compatibility mode, which is equivalent to a "temporary solution"

If you find that a program can only run in compatibility mode, it is recommended to pay attention to whether there is an official updated version, or see if there is an alternative. After all, relying on compatibility mode for a long time is not the most ideal approach.

Basically that's it. If you encounter the problem that old software cannot run, you might as well try this method.
