MS-DOS

Dos eh keese

active root directory in the case of c and d C and D both refer to drives and hard drives so in this case dos is asking for the correct directory of drives c and d because the old directory no longer exists.

You can uninstall FreeDOS..

You can use file name as filename.extension. File name in DOS can be maximum of 8 characters and extension is maximum of 3 characters. If you create any file having more character then it will automatically exclude the remaining characters. Say if you create dharmsansar then DOS will save it as dharmsa~..

Since dos is operating real mode, thus it's limited to 1mb memory. Himem.sys is a tool to extend the memory so programs can utilize more than just 1 mb.

The original Microsoft Disc Operating Systems did not have particular names but were simply given numbers. They were text based such as the command screen and prompt.
The first with a graphic user interface to be released generally was Windows 3.1, successors are;

Windows 95
Windows 98
Windows 98 SE
Windows Millenium
Windows 2000/ NT
Windows XP
Windows Vista
Windows 7

Within these are special editions for certain applications such as business users and those with particular needs, such as Server, Home, Premium, and Pro Editions etc

1. Shut down the computer and reconnect the keyboard.
2. Try to recover the system to earlier time.

Run "ipconfig".. If your Ethernet will be active it will show you the current IP address of NIC..

Now a days, no any site is running on DOS.

If I understand the question correctly, the command is "dir" (without the quotes), short for directory. That will show you all the files and sub-folders within the current directory. You can navigate around to other directories/folders as well... for general help with command prompt commands, when you're at the prompt type "help". (Again, no quotes.) It'll give you a list of commands.

If you need more detailed help with any particular command, like the dir command, type help dir.

In MS-DOS, the copy con command is used for the creation of files from the command line. From the command line enter "copy con" and the name of the file desired to be created.

• XCOPY/D : date

"copy <source> <destination>"

Many times we face this problem when we or our friends forget Windows XP password and can't log into Windows. So here we are posting a few methods / utilities which can be used to reset Windows password:

1rd Method:

Try following trick which is actually a loophole in Windows XP Setup and a big security hole:

A. Boot using Windows XP Setup CD and follow the instruction like Accepting EULA, etc.

B. When it asks to repair your existing Windows installation, accept it and press "R" to run the repair.

C. Setup will start repairing your Windows and will start copying files, etc.

D. After a few minutes setup will restart your system and when it restarts don't press any key when it shows "Press any key to continue..." otherwise Setup will start from the beginning. Don't press any key and setup will resume where it left.

E. Now it'll start doing other tasks and will show a small progressbar with a few details in left side.

F. Look carefully at the details and when it shows "Installing devices", press <Shift>+F10 keys in your keyboard.

G. It'll open a Command Prompt window. Now type nusrmgr.cpl and press <Enter>.

H. It'll open the same "User Accounts" window which you see in Control Panel.

I. Now you can remove or reset any account password without any problem.

If this method does not work then use third party software to reset windows admin password like Stellar password recovery software

Format

Use "prompt $p$g" command.

You can start registry editor using command prompt by using "regedit" command. You can also use registry tools such as "regedit /restore" or "regedit /fix" etc.

Just execute the setup file through DOS. Say if your Mozilla setup file "mozilla.exe" is in D drive then just run the below command:

C:\> d:

D:\> mozilla and press enter..

Utilities are programs that can run or execute. Commands are slightly different than utilities. Command refers to the name of the program and any arguments you specify to that program to change its behavior.

Modifies and Programmed for general computing purposses.

COPY leaves the original(s) intact; MOVE does not.
