Windows Command Line Hacks

Windows command line hacks are a set of commands or tools that can be used to perform certain tasks on a Windows system. These hacks can be used to perform various tasks such as managing files and folders, changing system settings, and troubleshooting problems.

There are a number of different ways to access the command line in Windows, but the most common method is to use the Command Prompt tool. This tool can be found in the Accessories folder of the Start menu. To open the Command Prompt, simply type „cmd“ into the search bar and press Enter.

Once you have the Command Prompt open, you can begin typing in commands. Some of the most common commands include „dir“ to list the contents of a directory, „cd“ to change the current working directory, and „copy“ to copy files. There are many other commands that can be used as well, but these are some of the most basic and commonly used.

Here are some useful commandline scripts for the advanced Microsoft Windows user.

Password Function

Here is a little password function if you need it. Be aware that it is very slow, don’t type too fast. 😉 It’s more a concept than a tool you can work with. Just Enter your password and hit ALT+222 (on your numblock) to terminate.

@echo off
setLocal EnableDelayedExpansion

set allchar=Þ1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
set pw=

echo Please enter password SLOWLY and terminate with ALT+222
choice /C %allchar% /CS >nul
set cint=%errorlevel%
set /a cint-=1
set pw=%pw%!allchar:~%cint%,1!
if %cint% neq 0 goto pwloop

set pw=%pw:~0,-1%
echo %pw%
set pw=

Can’t Print FAX files – Workaround

If you have FAX files and open them in Windows with the Windows Photo Viewer or Windows Picture and Fax Viewer you may experience the problem that you can’t print the FAX file. Microsoft has not released any patch for this for now.

There is a little workaround to rename the files to .TIFF. But if you have a lot of FAX files it is too much trouble for such a little problem.

  • Rightclick a FAX file
  • Select open with
  • Select the FAX.exe
  • Be sure to check the box: always open with this program

Here is the original FAX.cmd file

@echo off
set tmpf=%temp%\myFAX
set file=%~nx1

if not exist %tmpf% mkdir %tmpf%
if exist %tmpf%\%file% erase %tmpf%\%file%
if exist %tmpf%\%file%.tiff erase %tmpf%\%file%.tiff

copy %1 %tmpf%
cd %tmpf%
ren "%file%" "%file%.tiff"
start "" "%tmpf%\%file%.tiff"

This file can be converted with the Bat2Exe Converter and made an executable.

Quick Admin Check with Version info for Windows in Batch

A little script which checks for your Version and also tells you if you have Admin rights or not.

@echo off

rem ***************************************
rem Info:
rem ***************************************

ver | findstr "DOSBox\ version\ 0.72.\ Reported\ DOS\ version\ 5.0.">nul && echo DOSBox
ver | findstr "Windows\ NT.\ Version\ 4.0">nul && echo Windows NT

(mkdir %windir%\system32\test 2>nul && rmdir %windir%\system32\test) || goto error
echo User has admin rights
goto End

echo User has *NO* admin rights
goto End


Delete protected partitions with windows

Sometimes it comes to a time where you need to delete partitions with windows and the diskmanager is not able to. I got a harddrive with 6 windows partitions here. To delete them all you can use a commandlinetool called diskpart.

Start a console with administrative rights and type-in


After this you can list all your disks with

list disk

select your preferred disk. Best thing is to choose them by the size. If you have two equal sized disks just disconnect the one, list the disks and then connect it again, list the disks and you see which one is new.

DISKPART> list disk
Datenträger ### Status Größe Frei Dyn GPT
 --------------- ------------- ------- ------- --- ---
 Datenträger 0 Online 149 GB 0 B
 Datenträger 1 Online 119 GB 0 B

Now select the disk with

select disk 0

now you can list the partition

list partition


Partition ### Typ Größe Offset
 ------------- ---------------- ------- -------
 Partition 1 Primär 149 GB 1024 KB

now you can select the partition

select partition 0

and delete the partition with

delete partition override

the parameter override is needed for protected partitions. For more partitions and harddrives you can prepare something like this:

select partition 0
delete partition override
select partition 1
delete partition override
select partition 2
delete partition override
select partition 3
delete partition override
select partition 4
delete partition override
select partition 5
delete partition override
select partition 6
delete partition override

Batch – Choose a directory by number

If you like your users to manually choose a directory in you filesystem but do not want them to type in the complete name of it, just use following script.

@echo off
setLocal EnableDelayedExpansion
set i=0
set c=0
for /f "tokens=*" %%a in ('dir C:\temp /AD /b') do (
 set /a i+=1
 set dir!i!=%%a
 if !i! leq 9 (echo [ !i!] %%a)
 if !i! gtr 9 (echo [!i!] %%a)
set /p choice="Please choose: "
if !dir%choice%! equ ^!dir^%choice^%^! echo Your choice !dir%choice%! was not found. &goto choose
echo Your choice was !dir%choice%!
