SUMMARY
In Microsoft Excel you can programmatically obtain system status information and display it in a worksheet. This step-by-step article provides a sample Microsoft Visual Basic for Applications Sub procedure that displays the following information by using Windows API functions:
- The Windows version number with the GetVersionEx API function.
- The CPU processor type with the GetSystemInfo API function.
- The amount of free memory with the GlobalMemoryStatus API function.

To get Windows status information by using Windows API calls, follow these steps:
- Start Microsoft Excel, and then create a new workbook.
- On the Tools menu, point to Macro, and then click Visual Basic Editor (or press ALT+F11).
- On the Insert menu, click Module.
On the module sheet, type the following code:
Option Explicit Type SYSTEM_INFO dwOemID As Long dwPageSize As Long lpMinimumApplicationAddress As Long lpMaximumApplicationAddress As Long dwActiveProcessorMask As Long dwNumberOrfProcessors As Long dwProcessorType As Long dwAllocationGranularity As Long dwReserved As Long End Type Type OSVERSIONINFO dwOSVersionInfoSize As Long dwMajorVersion As Long dwMinorVersion As Long dwBuildNumber As Long dwPlatformId As Long szCSDVersion As String * 128 End Type Type MEMORYSTATUS dwLength As Long dwMemoryLoad As Long dwTotalPhys As Long dwAvailPhys As Long dwTotalPageFile As Long dwAvailPageFile As Long dwTotalVirtual As Long dwAvailVirtual As Long End Type 'The following three Declare lines must be each entered on a single 'line.
