How to make card compatible with Windows 8.1

My new Sandisk Extreme Pro SDXC 64 GB 95mb/sec UHS-I/U3 came with a paper stating that it is compatible with earlier versions of Windows, but nothing after Windows 7.  And my CPU running 8.1 does not recognize the card when inserted into it’s internal card reader.  Is there a way to make the card compatible with a CPU running Windows 8.1?


the card should be compatible with windows 8 also. so please ensure that you are using a sdxc compatible reader or sd slot with the pc. you can also try the card with another os to see if its there detected normally.

Sorry here is the rest

also you can check the drivers from windows maybe they are not updated correctly.
