Getting a users System Information (tricky)

Is there a way to get a users system information:
-Windown Version
-Remaining Disk Space
-Running Applications

and all that other good stuff?
any tips/tricks would be most usefull!

The following are quick samples from allapi.com:

1. Windows version

VB Code:

Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (lpVersionInformation As OSVERSIONINFO) As Long
Private Type OSVERSIONINFO
    dwOSVersionInfoSize As Long
    dwMajorVersion As Long
    dwMinorVersion As Long
    dwBuildNumber As Long
    dwPlatformId As Long
    szCSDVersion As String * 128
End Type
Private Sub Form_Load()
    Dim OSInfo As OSVERSIONINFO, PId As String
    'KPD-Team 1998
    'URL: [url]http://www.allapi.net/[/url]
    '[email protected]
    'Set the graphical mode to persistent
    Me.AutoRedraw = True
    'Set the structure size
    OSInfo.dwOSVersionInfoSize = Len(OSInfo)
    'Get the Windows version
    Ret& = GetVersionEx(OSInfo)
    'Chack for errors
    If Ret& = 0 Then MsgBox "Error Getting Version Information": Exit Sub
    'Print the information to the form
    Select Case OSInfo.dwPlatformId
        Case 0
            PId = "Windows 32s "
        Case 1
            PId = "Windows 95/98"
        Case 2
            PId = "Windows NT "
    End Select
    Print "OS: " + PId
    Print "Win version:" + str$(OSInfo.dwMajorVersion) + "." + LTrim(str(OSInfo.dwMinorVersion))
    Print "Build: " + str(OSInfo.dwBuildNumber)
End Sub

2. Disk free space

VB Code:

'In general section
Private Declare Function GetDiskFreeSpace Lib "kernel32" Alias "GetDiskFreeSpaceA" (ByVal lpRootPathName As String, lpSectorsPerCluster As Long, lpBytesPerSector As Long, lpNumberOfFreeClusters As Long, lpTtoalNumberOfClusters As Long) As Long
 
Private Sub Form_Load()
    'KPD-Team 1998
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
 
    Dim Sectors as Long,Bytes as Long,FreeC as Long, TotalC as Long,Total as Long,Freeb as Long
    'Retrieve information about the C:\
    GetDiskFreeSpace "C:\", Sectors, Bytes, Freec, Totalc
    'Set graphic mode to persistent
    Me.AutoRedraw = True
    'Print the information to the form
    Me.Print " Path: C:\"
    Me.Print " Sectors per Cluster:" + Str$(Sector)
    Me.Print " Bytes per sector:" + Str$(Bytes)
    Me.Print " Number Of Free Clusters:" + Str$(Freec)
    Me.Print " Total Number Of Clusters:" + Str$(Totalc)
    Total = rTotalc& * rSector& * rBytes&
    Me.Print " Total number of bytes in path:" + Str$(Total)
    Freeb = rFreec& * rSector& * rBytes&
    Me.Print " Free bytes:" + Str$(Freeb)
End sub

3. It's a little too much for posting here.
