Solution: Virtual Drives not working in Windows 8

If you are having problem loading Virtual Drives on Windows 8 (most probably after you upgraded from Windows 7 to Windows 8), the following should solve the problem.

• Open devmgmt.msc and see if you have yellow warning icon in front of your virtual drives. Try to reinstall the driver for them and see if it fixes it.
• If it doesn't then uninstall the drivers. Goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} and delete the following values
• UpperFilter
• LowerFilter

After deleting these two registry values, you should be able to see your virtual drives in the explorer. These keys created problem for all my native virtual drive and also with the CloneDrive. I had tried uninstall/reinstall of clone drive many a times but in the end it's the registry that always helps.
