## Gaining a command shell
|
||
|
||
* **Shortcut**
|
||
* [Window] + [R] -> cmd
|
||
* [CTRL] + [ALT] + [SHIFT] -> Task Manager
|
||
* [CTRL] + [ALT] + [DELETE] -> Task Manager
|
||
* **Access through file browser**: Browsing to the folder containing the binary (i.e. `C:\windows\system32\`), we can simply right click and `open` it
|
||
* **Drag-and-drop**: dragging and dropping any file onto the cmd.exe
|
||
* **Hyperlink**: `file:///c:/Windows/System32/cmd.exe`
|
||
* **Task Manager**: `File` > `New Task (Run...)` > `cmd`
|
||
* **MSPAINT.exe**
|
||
* Open MSPaint.exe and set the canvas size to: Width=6 and Height=1 pixels
|
||
* Zoom in to make the following tasks easier
|
||
* Using the colour picker, set pixels values to (from left to right):
|
||
* 1st: R: 10, G: 0, B: 0
|
||
* 2nd: R: 13, G: 10, B: 13
|
||
* 3rd: R: 100, G: 109, B: 99
|
||
* 4th: R: 120, G: 101, B: 46
|
||
* 5th: R: 0, G: 0, B: 101
|
||
* 6th: R: 0, G: 0, B: 0
|
||
* Save it as 24-bit Bitmap (*.bmp;*.dib)
|
||
* Change its extension from bmp to bat and run
|
||
|
||
|
||
## Sticky Keys
|
||
|
||
* Spawn the sticky keys dialog
|
||
* Via Shell URI : `shell:::{20D04FE0-3AEA-1069-A2D8-08002B30309D}`
|
||
* Hit 5 times [SHIFT]
|
||
* Visit "Ease of Access Center"
|
||
* You land on "Setup Sticky Keys", move up a level on "Ease of Access Center"
|
||
* Start the OSK (On-Screen-Keyboard)
|
||
* You can now use the keyboard shortcut (CTRL+N)
|
||
|
||
