Tutorial: Fix V4W issue related to Windows 10

Configurator keep saying "V4W can be installed" or popup a message box "Access XXXXXX\FxProperties failed. Please take ownership of the registry key manually."

Manually take ownership the following registry key with RegOwnershipEx
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{GUID} HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{GUID}\FxProperties
Replace GUID with Device GUID (Configurator -> Select Device -> Copy Device GUID)
e.g. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{6617710e-237b-4b0b-8d8b-4a3cfdc6f08b}

Error Technical info: Access to path ‘C:\Program Files\ViPER4Windows\LocalPreset.bin’

Run cmd as admin, type
takeown /f "C:\Program Files\ViPER4Windows" /r /d n
takeown /f "C:\Program Files\ViPER4Windows\LocalPreset.bin" /r /d n
cacls "C:\Program Files\ViPER4Windows" /t /e /p administrators:f
cacls "C:\Program Files\ViPER4Windows" /t /e /p users:f
Restart ViPER4Windows.
If this problem still exist, manually take ownership of ViPER4Windows folder and LocalPreset.bin file.

V4W audio effects still not apply on playback devices
