Every time I encounter a Windows system update, one of the topics that everyone cares about most is compatibility. In fact, this is Microsoft's biggest headache. The Windows family has accumulated wealth and burdens for so many years. In particular, Windows 7/8.1 can be upgraded directly for free, and compatibility has become a top priority.
Microsoft also acknowledges that compatibility issues are inevitable, but efforts have been made to identify and resolve all issues, especially in the case of user upgrades in time. After all, it is not easy to upgrade the problem.
This is mainly divided into three aspects:
1, application compatibility
This is definitely the easiest to encounter. Simply put, it runs well on Windows 7/8.1. The program, upgrade to Windows 10, went on various errors or strikes, and even caused the system to crash.
Microsoft said that if such an application is detected during the upgrade process, users are advised to delete it first because they will also interfere with system installation and setup, resulting in an upgrade failure.
But facing the new system that is so important to Windows 10, I believe that most developers will quickly catch up and ensure that their applications are compatible.
Of course, if you are running an older version of an app, it's best to upgrade to the latest version first. If you are nostalgic, you need a version, or you hate that the new version is too bloated and complicated, so you have to be at your own risk.
2, device compatibility
This problem is more headaches, the cost is much higher than the application compatibility, and there are not many solutions: either temporarily disable or replace the device.
Although the hardware requirements of Windows 10 are not high, basically similar to Windows 7/8.1, but this does not mean that the normal devices can still be used. After all, the functions of the new system are more advanced, and may not appear. Support for higher resolution display, missing device features, etc.
3, set compatibility
If you are a "lazy", you are used to the default settings, then don't worry about this problem, but if you like toss, modify the system everywhere And the configuration of the software, it may lead to some parameters to prevent Windows 10 upgrade.
At this time, either you find out where the problem is (more difficult), or simply install Windows 10 directly, but remember to back up your personal data.
