> So we need to find what is the value of
`Services.sysinfo.getProperty("version")` on Windows 7.
The short answer is "6.1".
The longer answer is that `PR_GetSystemInfo()` is used by
`Services.sysinfo` to obtain OS version information. On Windows, the
implementation is in `_MD_WindowsGetSysInfo()` which constructs a string
as `dwMajorVersion`.`dwMinorVersion` from a `OSVERSIONINFO` struct that is
filled in via a call to the Windows API function `GetVersionEx()`. I used
the Firedox browser console in to obtain the `6.1` answer, and it matches
the data in the table that is included in the following page:
