Windows Explorer – add Open a Command Line Here to your right click menu

http://www.petri.co.il/add_command_prompt_here_shortcut_to_windows_explorer.htm has details of how to do this 5 different ways.
Unfortunately there's a small error in the one about editing the registry, although it might be the simplest:

  1. Copy and paste these lines into a CommandLineHere.reg file on your desktop. Do include a carriage return at the end.
  2. Double-Click it.
  3. Say yes.
  4. Now right-click on a Folder and voila.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Command Line]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Command Line\command]
@="cmd.exe /k pushd %1"

Can’t Find Groups Management On Windows 7 Home and Vista Home Editions

How to Manage Local Groups on Windows Home

Ever helpful, Microsoft provides a GUI interface for managing users and groups on Windows. Unless you have a Vista home edition or a Windows 7 home edition, in which case you can't find the interface to manage groups because it isn't there. You can however manage groups very easily from the command line.

Manage Windows Groups from the Command Line

Simples. Find Command Line in your Start Menu Programs so that you can right-click on it and choose 'Run As Administrator'
Type:

net localgroup /?
net localgroup MyNewGroupName /Add
net localgroup MyNewGroupName MyFirstUserName /Add
net localgroup MyNewGroupName MySecondUserName /Add
... and so on

And voila. You can now set security on folders in explorer, and use your new group to grant access.
If your Windows permissions are not working after you've granted new permissions, the usual trick is to lock and unlock your session (Start Menu -- The Power/LogOff/Hibernate/Lock/Sleep button). Failing that, log out and back in again.

iTunes Home Sharing Not Working

There's a handful of reasons that can cause this. The probably definitive list can be found by combing the apple tech support discussion thread for it at https://discussions.apple.com/thread/2586385?start=105&tstart=0
I recommend you start at the end of the thread where you'll find the answers rather than at the beginning of the thread where'll you find the kind of posts that people write when they're tearing their hair out because their shiny expensive toy DOESN'T WORK.
The one that worked for me was:

  • Restart the windows Bonjour service. If you don't know how to do that, just restart your computer.
  • The other popular one is: "Sorry bud, you need a new router." Or if you're 'lucky' just a firmware update (Have you ever tried updating your router firmware? I did it once). You can't win then all.
