Win XP to Win 7 migration application compatibility solution

This article mainly introduces three simple and straightforward methods to solve the application compatibility problems in the Windows XP to Windows 7 migration process.

1. Application Upgrade

If there is an upgrade method that can solve the compatibility problem when the application is used for the new operating system, then this will be the fastest and easiest way to solve the compatibility problem. . However, the upgrade may be subject to a fee, or the original application version may not support the upgrade.

Upgrading Available Resources

The Application Compatibility List is being updated quickly and will also list the version number of the application currently supporting the upgrade. Of course, sometimes you can also contact third-party software developers to directly develop and provide their Windows Vista/Windows 7 compatibility solution.

2, repair source

If you can get the source code of the application, then you can make it compatible with the new operating system by fixing the source code. With this approach, you need to pay for the development source you need to resolve compatibility issues, and you need to spend time on project management and end-customer testing.

3. Adding an interface to an application

In a nutshell, an interface is a piece of code that sits between the application and the operating system and intercepts and fixes the interaction between the application and the operating system. effect. In some cases, the application could have been run on Windows 7, but since the developer set up the operating system version detection, the application could only run on XP. In this case, an interface is added so that when the application launches and detects the operating system version, the interface blocks version detection and gives a response: the system is an XP system.

The interface can intercept hundreds of system version detections. You can consider using the interface when:

1, when an application vendor no longer produces or provides such an application;

2, when an application Is developed internally, but does not provide source code or no developer know how to modify the source code;

3, when you are waiting to use a compatible version of an application, and temporarily only the previous version can be used.

The interface data is stored in an interface database. First, the interface data is deployed to each workstation and then installed through the command line. Your professional IT developer needs a strategy to manage the database, deploy and install interface data.

Microsoft Windows application compatibility infrastructure is an effective solution to implement programming interface hook procedures. Moreover, it can be fundamentally located from Windows itself, or from another party's code - the interface itself's Application Interface Programming (AIP) call link.

The evolution of the Windows operating system from one version to another is by changing settings to support new technologies, fix bugs, and implement remediation strategies, and changing the implementation of some functions may affect applications based on these. program. Given the nature of the software itself, fixing compatibility issues by modifying the functionality may affect more applications, or Windows needs to preserve these imperfect improvements that can be provided by middleware.

The Application Compatibility Toolkit (ACT) includes hundreds of widely used third-party application interfaces. Other applications, such as business-wide applications developed in-house, may provide Windows 7 Compatible interface.
