I added keys for 32bit and 64bit for phpdesktop-msie.exe select version IE 10 like bleow.
32 bits: [(HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE)\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
64 bits: [(HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE)\Software\wow6432node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"phpdesktop-msie.exe" = dword 10000 (Hex: 0x2710)
but still phpdesktop render IE7.
What did I miss?
