The Windows Command Line Beginner's Guide Quotes

“Generally, when working on a computer, it is always a good idea to back up the contents of the C:\Users directory. Especially if it is the personal machine of a technically unskilled user – the user will almost always claim that he or she doesn’t “have anything important” on the machine if you need to wipe the hard drive and reinstall Windows. Nevertheless, if you do wipe the machine and reinstall Windows, a few weeks later the user will become irate when he notices that “all his stuff is missing” – and of course the user has no backup copies! It is therefore always a good idea to back up the C:\Users directory when repairing a Windows computer. ”

“Unlike Linux or Mac OS X, the Windows Command Prompt is not case sensitive, and does not distinguish between commands or filenames based up the case of the letters in the file name. To return to the previous example, the Command Prompt will interpret COPY, Copy, and copy as the same thing - every one of these will launch the copy command. In the same vein, Command Prompt will view Report.doc, REPORT.doc, and report.doc as the same file”

“Copying text in this way is rather cumbersome. There is a way to speed it up. If you right-click on Command Prompt’s title bar and click on Properties, this will take you to the Properties dialog box. Most of the Properties dialog box’s tabs let you control the shape, color, and font size of the Command Prompt. But under the options tab, there is a check box labeled “Insert Mode.” If you check that, it will be as if the Mark option is turned on in Command Prompt all the time – you can highlight text simply by left-clicking and dragging the mouse cursor over it, rather than going to the menu, selecting Edit, and then clicking on Mark every time you want to copy some text. ”

“Because of this, Command Prompt usually opens with the permissions of a standard user, even when you launch it from an administrator's account. This means you won't be able to use Command Prompt to launch any commands that alter the system or install programs. To do so, you will need to run Command Prompt as an administrator.  Fortunately, running any program as an administrator within Windows is easy. Simply right-click on the icon for Command Prompt and select "Run as administrator" from the context menu that appears (it will have the multicolored shield icon of the UAC prompt next to it). If you're running within an administrator account, you need only click Yes to continue; if you're using a standard user account, you'll need to enter an administrator's username and password. Once Command Prompt opens as an administrator, the program's title bar will change from "Command Prompt" to "Administrator", and you can now launch commands that will affect system settings.”
