How to install non supporting / incompatible drivers in Windows 8

I has not been very long since the Windows 8 has released, so there exists the problem of driver support.

I has not been very long since the Windows 8 has released. There are several app that are still not available /
 compatible windows 8. Previously in my old post, i have mentioned a way about how to install old drivers in windows 8 in case the driver installer is not supported, you can check it here
"How to install old unsupported drivers in windows 8"
In this post, we will discuss about how to install drivers that get rejected by Windows 8 during some integrity or signature test or other support issues.
This method will not work for all case, but for  most of the cases.

All you have to do is to open Command Prompt with administrator privileges, and enter some commands.

Command 1
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS

Command 2
bcdedit -set TESTSIGNING ON

and reboot the system.

If you have problem in copying the text above, you can download it from here.

NOTE:- After this your windows 8 will display a message in the right bottom of desktop that it is running in TEST Mode, you can revert the above commands to remove this message after completing your work.

Command 1
bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS

Command 2
bcdedit -set TESTSIGNING OFF

This method helped me in several cases, specially in installing Flashtool drivers in Windows 8 for Xperia.
