Windows8 system Metro (Modern UI) interface application installation failure solution

Many students react to Win8 Metro applications often encounter installation failures, re-installing the application does not help, always appear hangs, then there is no reacted. Excluding Win8 is still not perfect, the big reason is due to the optimization of Win8.

The installation failed application can also display the big square icon on the Modern UI interface, but there will be a small cross symbol (X) in the lower right corner of the square icon. The application system will prompt you to open the application system. Lets you reinstall the fix to the app store. These applications are inherently problem-free, and the chances of system bugs are small. The only reason is that students are habitually optimizing the system.
Metro Application Installation Failure Solution:

The Metro application will have a suspend prompt before the installation fails, and you will be prompted to install the app later.

The application should not be considered from the following aspects:
Windows Update service is turned off, just reopen it (if Windows Update is disabled, various problems will occur, often Will cause a high CPU usage.) Windows Firewall is turned off, if it is already started, stop and start again. Cache problem, some applications may be uninstalled and then installed, then the cache file problem can not be installed, the cache file can be cleaned up, there are not many software that can clean Win8 cache file, I know the soft media Win8 The optimization master is one of them. The last one is prevention. When you are fine, don't move some system directories, such as: Windows app directory, don't delete files, unless you really know what the file is, and what happens after deletion.

The above method has been verified to solve the problem of not being able to install the application, but there are many reasons for causing system problems, and there is no guarantee that 100% of the students can not be installed.
