Windows7 system software compatibility issues

Microsoft since October 2009 since the release of Windows 7 has been 20 months, and received universal acclaim. The system is designed to make people's daily computer operations simpler and more efficient and easy to work.

CNET comments represent, "Windows 7 is a reliable platform, enough to compete with Mac OS X, Microsoft on behalf of its birth is still to launch a strong, useful operating system." According to the US market research firm Net According to data released by Applications, more than 20% of Windows users worldwide use Windows 7 systems. Windows 7 is also the fastest selling Windows system in Microsoft's history. Windows 7 allowed Microsoft to step out of Vista's embarrassment on the operating system and rebuild Microsoft's reputation.

Compatibility is a major drawback of Vista. At the beginning of the release, there were many problems with software and hardware incompatibility. However, after several years of development, all problems have been solved one after another. Windows7 catch the "ride" is the same as its core and Vista, according to Microsoft, if your software can run correctly on Vista, it must be able to smooth the transition to 7 Wndows.

But for those programs that can run on XP but not on Vista, Windows 7 is not compatible. To solve this problem, Windows 7 provides a solution: compatibility mode. Unable to find a running program's executable file, right-click and select Properties, switch to the Compatibility tab, before the previous "run the program in compatibility mode" box point hook, generally choose to run Windows Xp sp2.

In Windows 7, a lot of software can't run because there is no administrator rights. Right click on the executable and select "Run as administrator" and confirm in the pop-up UAC menu.

Windows 7 to solve the compatibility problem has also introduced a new feature: Windows XP Mode, also known as XP compatibility mode, this mode is intended to solve some of the applications under Windows 7 is not compatible with specially formulated, Through it, these applications may get run in XP compatibility mode. The Windows 7 version including the "XP Mode" function is as follows: Professional, Ultimate, and Enterprise. XP Mode has corresponding hardware requirements. It requires 32-bit or 64-bit processors with hardware virtualization technology above 1 GHz. At least 1.25 GB of memory, more than 2 GB of memory is recommended, and more than 15 GB of free disk space is required. To install an application in Virtual Windows XP, you can run the installer from a CD-ROM media, a USB storage device, or a virtual machine to access a local disk that has already been mapped. After the program is installed, shut down the virtual machine. When you need to run the application in virtual Windows XP mode, click, all programs, Windows Virtual PC, under the "Virtual Windows XP Application" folder, you can run in Windows XP mode by clicking the corresponding program shortcut. After the program starts, the user starts. Only the window of the program interface will be obtained, and the system will not display the Windows XP desktop. In the user's opinion, this program is just like running on local Windows 7. However, XP mode also has some shortcomings. In order to improve compatibility, XP mode has made many restrictions on the function and performance of hardware. For example, in XP mode, the graphics card does not have 3D acceleration and only supports 16-bit color display.

Under the influence of a solid market share, almost all software and hardware products regard Windows XP as a standard platform. Compatible with Windows XP is almost compatible with everyone's computer. In this relatively single computer. In the environment, compatibility issues almost never appear on Windows XP. Windows 7, a young and historic system, will surely achieve impressive market share over time like its predecessor, Windows XP, and its software compatibility issues will inevitably be resolved.
