Open a Run command box by pressing the Windows key and R key at the same time. You can also do this by searching "Run" in your Start menu's search bar.
In the Run window's dialog box, type msinfo32 and click OK.
When the System Information window opens, give it a moment to pull information from your system. You’ll know it’s done when you click through the menus on the left and see information for each of them.
Click File, then Export... Do not choose File, then Save as. This will create a very large file that you may not want on your system.
Name your file something simple, like "mymsinfo", and make sure it’s saved as a text (.txt) file.
Save the exported file somewhere you can easily find it, like your Desktop or your My Documents folder. It can take a minute or two for the file to export and save.
