I need to find out what Windows and Service Pack system is currently running. All I have is ftp access, it means I cannot run any the software.

Is there a way to determine what version of Windows, Service Pack, and what Language is installed on a system?

  • pull the entire registry SAM? – Richie Frame Jan 15 '16 at 4:19
  • It's protected. Windows doesn't let to copy it. – Dranik Jan 15 '16 at 4:25
  • There are programs that will use the packets from the network of the machine to fingerprint the OS. It will not be as details as you want, but it's something. – schroeder Jan 15 '16 at 4:43
  • What kind of access do you have to the filesystem? Can you search the whole c:\system directory? – schroeder Jan 15 '16 at 4:43
  • "nmap -O" will give you some details. – N. Greene Jan 15 '16 at 14:46

Based on https://superuser.com/questions/363018/how-do-i-tell-what-version-and-edition-of-windows-is-on-the-filesystem you can find the Windows Version and Service pack in C:\Windows\System32\license.rtf for Windows 7. For Windows XP the information is in C:\Windows\System32\eula.txt. For Windows 10 licenses.rtf does not contain the version. Instead it contains the EULA code, which you can use to find the version online.

I tested this on XP SP3, 7, 7 SP1, and 10 and found that this works for each OS.

The current language pack is a little more tricky. You can find what appears to be the currently available languages in C:\Windows\System32. The folders are in the format of xx-XX (xx = language, XX = country). For example en-US is English-United States, es-MX is Spanish-Mexico.

The packs that have been used are copied to C:\Windows.

To test this I switched my Windows 7 SP1 and Windows 10 Pro machines over to es-MX and, once I rebooted the computer, found that the es-MX folder was created in C:\Windows. Unfortunately the en-US was still there making the current language ambiguous. However you should be able to use the combination of active packs and the names of Documents, Photos, Music ect. to get the current language.

I was unable to test this in XP as I could not risk bricking my last running example of XP.

  • Go ahead and brick it. It's well overdue. – Iszi Jan 20 '16 at 15:52
  • Also, I wish I could brick it but I still need to support XP users which involves testing. – AstroDan Jan 20 '16 at 16:27
