OSI: User's Guide

OSI is in progress: more information categories are being added.

Downloads & Runtimes

Download the latest release from the Releases page.

Folder Target Framework Architecture Required Runtime
net10.0 x64 .NET 10.0 64-bit .NET 10.0 Desktop Runtime (x64)
net10.0 x86 .NET 10.0 32-bit .NET 10.0 Desktop Runtime (x86)

On 64-bit Windows 10/11, use x64. The plain ".NET Runtime" is not enough; OSI needs the Desktop Runtime. To check which runtimes are installed, run dotnet --list-runtimes and look for a Microsoft.WindowsDesktop.App 10.x line.

Install

OSI is portable: there is no installer.

  1. Download and extract the folder that matches your system, e.g. net10.0 x64.
  2. Copy the whole folder to a permanent location, for example D:\My Apps\OSI\. Keep all the files together: OSI.exe loads the modules modWindows.dll, modHardware.dll and SharedInterfaces.dll, and needs System.Management.dll and the runtimes folder.
  3. Double-click OSI.exe.

If Windows blocks the file ("Windows protected your PC"), right-click OSI.exe → Properties → check Unblock → OK, then try again.

Usage

Click a category in the tree on the left; its information is shown on the right. The progress bar shows how far the information is read.

Category Information (WMI class)
OS Windows edition, version, build, codename, release date and end of support (Win32_OperatingSystem, Win32_ComputerSystemProduct)
Windows → Environment Variables All environment variables (Win32_Environment)
Windows → User Account The user accounts of the computer (Win32_UserAccount)
Hardware → BaseBoard Motherboard (Win32_BaseBoard)
Hardware → BaseBoard → BIOS BIOS (Win32_BIOS)
Hardware → Battery Battery, on laptops (Win32_Battery)
Hardware → Disk Drive Physical disks (Win32_DiskDrive)
Hardware → KeyBoard Keyboards (Win32_Keyboard)
Hardware → Memory Memory modules (Win32_PhysicalMemory)
Hardware → Processor CPU (Win32_Processor)

Command line (in progress)

OSI.exe /host:<computer> /user:<user> /pass:<password>

These switches are read, but reading the information from a remote computer is not finished yet: OSI always shows the local computer.

Uninstall

Delete the folder you copied in step 2 of Install. OSI doesn't write any settings.
