Windows tips

🕑 Display Windows start-up date and time:

  • open a PowerShell terminal (WIN+R, powershell, ⮠ )
  • type the following command: (gcim Win32_OperatingSystem).LastBootUpTime

 

▶️ Launch programs at start-up (Windows 7 and above):

  • open the start-up directory by running (WIN+R):
    • shell:startup for personal use
    • shell:common startup for common use
  • put shortcuts you want to launch at start-up in that directory

 

🔗 Get the shortcut of an application pinned in the taskbar (Windows 7 and above):

  • type WIN+R and run shell:user pinned
  • enter the TaskBar directory, it should contain shortcuts to these applications
  • there may also be an ImplicitAppShortcuts directory containing other shorcuts

 

🚐 Display HTTP proxy settings:

netsh winhttp show proxy

 

🥇 Set the window of an application always on top of others knowing its PID (Windows 7 and above):

  • open a PowerShell terminal (WIN+R, powershell, ⮠ )
  • replace the value of the target PID in this script and run it:
$targetPID = 12345
$signature = @'
[DllImport("user32.dll")] public static extern bool SetWindowPos(
IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
'@
$api = Add-Type -MemberDefinition $signature -Name NativeAPI -Namespace NativeAPI -Using System.Text -PassThru
$window = (Get-Process -id $targetPID).MainWindowHandle
$api::SetWindowPos($window, -1, 0, 0, 0, 0, 0x0003) # use -2 instead of -1 to cancel the
  • this other script does the same in a more advanced manner: a GUI is shown to select the targeted window without having to know its PID

 

📂 Mount a directory as a drive:

subst D: C:\DATA

 

🔒 Lock current session:

  • from the keyboard: WIN+L
  • from the command line: rundll32.exe user32.dll,LockWorkStation

 

➰ Trigger CTRL+ALT+END from a Remote Desktop session to get the same behaviour as CTRL+ALT+DEL.

 

😃 On a French AZERTY keyboard, use the WIN+; shortcut to access the emoji pop-up window.
