;
; LogicLib extensions for handling Windows versions and service packs.
;
; IsNT checks if the installer is running on Windows NT family (NT4, 2000, XP, etc.)
;
;   ${If} ${IsNT}
;     DetailPrint "Running on NT. Installing Unicode enabled application."
;   ${Else}
;     DetailPrint "Not running on NT. Installing ANSI application."
;   ${EndIf}
;
; IsServerOS checks if the installer is running on a server version of Windows (NT4, 2003, 2008, etc.)
;
; AtLeastWin<version> checks if the installer is running on Windows version at least as specified.
; IsWin<version> checks if the installer is running on Windows version exactly as specified.
; AtMostWin<version> checks if the installer is running on Windows version at most as specified.
;
; <version> can be replaced with the following values:
;
;   95
;   98
;   ME
;
;   NT4
;   2000
;   XP
;   2003
;   Vista
;   2008
;   7
;   2008R2
;   8
;   2012
;   8.1
;   2012R2
;   10
;
;   Note: Windows 8.1 and later will be detected as Windows 8 unless ManifestSupportedOS is set correctly!
;
; AtLeastServicePack checks if the installer is running on Windows service pack version at least as specified.
; IsServicePack checks if the installer is running on Windows service pack version exactly as specified.
; AtMostServicePack checks if the installer is running on Windows service version pack at most as specified.
;
; Usage examples:
;
;   ${If} ${IsNT}
;   DetailPrint "Running on NT family."
;   DetailPrint "Surely not running on 95, 98 or ME."
;   ${AndIf} ${AtLeastWinNT4}
;     DetailPrint "Running on NT4 or better. Could even be 2003."
;   ${EndIf}
;
;   ${If} ${AtLeastWinXP}
;     DetailPrint "Running on XP or better."
;   ${EndIf}
;
;   ${If} ${IsWin2000}
;     DetailPrint "Running on 2000."
;   ${EndIf}
;
;   ${If} ${IsWin2000}
;   ${AndIf} ${AtLeastServicePack} 3
;   ${OrIf} ${AtLeastWinXP}
;     DetailPrint "Running Win2000 SP3 or above"
;   ${EndIf}
;
;   ${If} ${AtMostWinXP}
;     DetailPrint "Running on XP or older. Surely not running on Vista. Maybe 98, or even 95."
;   ${EndIf}
;
; Warning:
;
;   Windows 95 and NT both use the same version number. To avoid getting NT4 misidentified
;   as Windows 95 and vice-versa or 98 as a version higher than NT4, always use IsNT to
;   check if running on the NT family.
;
;     ${If} ${AtLeastWin95}
;     ${And} ${AtMostWinME}
;       DetailPrint "Running 95, 98 or ME."
;       DetailPrint "Actually, maybe it's NT4?"
;       ${If} ${IsNT}
;         DetailPrint "Yes, it's NT4! oops..."
;       ${Else}
;         DetailPrint "Nope, not NT4. phew..."
;       ${EndIf}
;     ${EndIf}
;

;    * IsStarterEdition
;    * OSHasMediaCenter
;    * OSHasTabletSupport
