FREEZE Jeff Prosise
Command l986/No. 22


Purpose: Ensures confidentiality of in-memory data
when it is necessary to leave a PC running
without storing the data to a removable
medium or encrypting it. FREEZE temporarily
suspends program operation, blanks the
screen, and disables the Ctrl-Alt-Del reboot
sequence until a user-entered password (up to
64 characters) is re-entered.

Format: [filespec]FREEZE

Remarks: FREEZE is a memory-resident utility, normally
loaded by an AUTOEXEC.BAT file. After
loading, the machine is "locked" by pressing
Alt-NumLock and then entering the passphrase
of choice. The passphrase may include any
characters except Esc and Enter. Pressing
the Esc key aborts password entry, and
pressing Enter initiates the lockdown.

The Backspace key may be used to correct
incidental mistakes, but care must be
exercised, as the characters are not echoed
on the screen during entry. To unlock the
machine, simply re-enter the same password
and press Enter. Again, the Backspace and
Esc keys can be used to correct or abort
password entry.


1. The password is never stored and may be
changed each time FREEZE is invoked with
Alt-Numlock. If an attempt is made to
load FREEZE.COM more than once, an error
message will result.

2. While FREEZE is believed compatible with
most other memory-resident programs,
because of the importance of data with
which it is expected to be used, it
should be thoroughly checked out in your
specific configuration. In particular,
FREEZE should be loaded before SideKick.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
