Alternate method:
Press (Windows)+R.
Paste explorer.exe shell:::{8E908FC9-BECC-40f6-915B-F4CA0E70D03D}
or the command previously provided above.
After testing, create a shortcut using either one of those commands and assign it a hotkey sequence... use said hotkey to launch in the future. Check out %SystemRoot%\System32\netcenter.dll
for viable shortcut icons...
While this, of course, doesn't fulfill your "use everywhere" requirement, you could create an installer batch script on a flash drive and bring that everywhere with you.
Realistically, the fastest method (for use with any Windows 7 system) might be to press or Ctrl+Esc, type "sharing", and, when "Network and Sharing Center" is highlighted,
press Enter.
is there any other option in Microsoft.* namespace?? – AminM – 2015-02-28T18:50:56.487
This only works if user is granted permissions to Network and Sharing Center. My institution blocks this with global policies for standard users. Giovanni's method works, even when not given permissions. – None – 2016-02-24T18:47:23.537
