Administrator password can be broken by replacing sam file in system32config by the sam file in repair folder of windows. It can be easily done on a machine with dual operating systems, simply log on to os other then the one whoes password is to be cracked the way is exactly same as written above but if there is a single os on a machine then there is only one way i.e to use ms dos start up disk or some other boot disk and replace the sam file in config folder with the one in repair folder  note:- this method works only if hard drive is FAT32 formatted because NTFS drive doesn't take boot from Ms DOS  This way you can remove the old administratOr password as if the windows is newly installed and the password was'nt set

I have forgot my administrator password an I have not bootable CD how to break it easily ?

No you can't break the administrative password in DOS mode. As far as my knowledge goes, it can't break in windows too.

I don't know of ways to do this from a command prompt. But it is possible to get around the admin password on most current versions of Windows using a boot disk...
CAUTION -- if this is not your personal machine, it is probably illegal to attempt to get around password protection.
That being said ... What operating system? And do you just want to reset the password to get into a machine, or recover the existing one(s)?
If it is NT4, 2000 or XP, there are several tools and tutorials available for either case. Generally they involve using a Linux boot disk, capable of reading the NTFS file system, and a tool that either rewrites the password file, or copies the password hash file and attempts to crack it.
Two such tutorials, and links to the tools they use, can be found at the following sites:

or

...or use your favorite search engine and look for "administrator password" and "recover" or "reset"
