there is a plugin here: nsis.sourceforge.net/GetVersion_%28Windows%29_plug-in
or you can use this function
; GetWindowsVersion
;
; Based on Yazno's function, http://yazno.**********/powerpimpit/
; Returns on top of stack
;
; Windows Version (95, 98, ME, NT x.x, 2000, XP, .NET Server)
; or
; '' (Unknown Windows Version)
;
; Usage:
; Call GetWindowsVersion
; Pop $R0
; ; at this point $R0 is "NT 4.0" or whatnot
Function GetWindowsVersion
Push $R0
Push $R1
ReadRegStr $R0 HKLM "SOFTWARE\Microsoft\Windows NT\CurrentVersion" CurrentVersion
StrCmp $R0 "" 0 lbl_winnt
; we are not NT.
ReadRegStr $R0 HKLM SOFTWARE\Microsoft\Windows\CurrentVersion VersionNumber
StrCpy $R1 $R0 1
StrCmp $R1 '4' 0 lbl_error
StrCpy $R1 $R0 3
StrCmp $R1 '4.0' lbl_win32_95
StrCmp $R1 '4.9' lbl_win32_ME lbl_win32_98

StrCmp $R1 '5.2' lbl_winnt_dotNET lbl_error
lbl_winnt_x:

Goto lbl_done
lbl_winnt_2000:

To detect Windows version plus service pack you may use this plugin by Afrow UK.
Otherwise there is the included header WinVer.nsh, find it into include folder under NSIS installation.

The script above is great but needs some corrections.It doesn't detect XP,first line skip it to lbl_error
StrCmp $R1 '5.0' lbl_winnt_2000 lbl_error
StrCmp $R1 '5.1' lbl_winnt_XP lbl_error
StrCmp $R1 '5.2' lbl_winnt_dotNET lbl_error
StrCmp $R1 '5.0' lbl_winnt_2000 0
StrCmp $R1 '5.1' lbl_winnt_XP 0
StrCmp $R1 '5.2' lbl_winnt_dotNET lbl_error
StrCmp $R1 '5.0' lbl_winnt_2000 lbl_error
StrCmp $R1 '5.1' lbl_winnt_XP lbl_error
StrCmp $R1 '5.2' lbl_winnt_dotNET lbl_error
StrCmp $R1 '5.0' lbl_winnt_2000 0
StrCmp $R1 '5.1' lbl_winnt_XP 0
StrCmp $R1 '5.2' lbl_winnt_dotNET lbl_error
