I have been searching and searching and have not come up with a good answer. I am trying to query the registry in both the locations for a software's UninstallString.
-HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall
-HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
The UninstallString needs to be set to a variable or piped straight in to run the msiexec.exe /x {GUID} /qn.
I would prefer this to be in powershell or command just my ease of use.
#ECHO OFF
SETLOCAL
set "uninstall1="
FOR /F "tokens=2*" %%A IN (
'REG QUERY "HKLM\Software\Microsoft\Windows\CurrentVersion" /v Uninstall'
) DO (set Uninstall1=%%B)
set uninstall
This should retrieve the first string, if it exists.
Repeat the formula for the second string. The final SET uninstall is merely to report the environment variables starting UNINSTALL for verification.
Then
if defined Uninstall1 msiexec ... "%Uninstall1%"
should execute MSIEXEC with the parameters you require (where ... are your options - /x, /qn whatever)

so my problem is that when i just ran cmd.exe in terminal, i get "& was unexpected at this time." Error at the end - looks like this
So the problem is that i'm getting erros in Unity 3D when it wants to run the unity_csc.bat file and compile solution. These errors are exactly the same as the one when i just run cmd.exe - therefore i suspect its not an Unity3D based problem (if you want you can check the Unity3D specific thread here https://forum.unity.com/threads/2-empty-errors-in-console-was-unexpected-at-this-time.799110/ )
Does anyone know why this might be happening ? This also happens when i try to run a .bat file - which I suspect is why i cant compile Unity project
I'm running Windows 10 with all of the latest updates
EDIT:
Since cmd /d does not throw the error, might there be some problem with this registry record ?
In User Folder i do have this Autorun record
#mode 20,5 & tasklist /FI "IMAGENAME eq SoundMixer.exe" 2>NUL | find /I /N "SoundMixer.exe">NUL && exit & if exist " ( start /MIN "" " & tasklist /FI "IMAGENAME eq explorer.exe" 2>NUL | find /I /N "explorer.exe">NUL && exit & explorer.exe & exit ) else ( tasklist /FI "IMAGENAME eq explorer.exe" 2>NUL | find /I /N "explorer.exe">NUL && exit & explorer.exe & exit )
Stephan has provided the crucial pointer:
It sounds like you have a broken autorun command defined for cmd.exe; that is, your registry defines a command that is automatically executed whenever you call cmd.exe, and that command causes the syntax error you're seeing.
Note that such commands are executed irrespective of whether you open an interactive cmd session or invoke via a batch file or pass a command to cmd with /C.
Passing /D to cmd bypasses any autorun commands.
There are two locations in the registry where such a command can be defined, one at the local-machine level (which applies to all users), HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor, and another for the current user only, HKEY_CURRENT_USER\Software\Microsoft\Command Processor, in a value named AutoRun.
If commands are defined in both locations, the HKEY_LOCAL_MACHINE's commands run first.
To list any defined autorun commands:
Get-ItemProperty -ea Ignore ('HKCU:', 'HKLM:' -replace '$', '\Software\Microsoft\Command Processor') AutoRun
You can use the following PowerShell snippet to remove autorun commands from both locations, but note that you'll have to run it with elevation (as administrator), if a local-machine value is present:
Get-ItemProperty -ea Ignore ('HKCU:', 'HKLM:' -replace '$', '\Software\Microsoft\Command Processor') AutoRun |
Remove-ItemProperty -Name AutoRun -WhatIf
Note: The -WhatIf common parameter in the command above previews the operation. Remove -WhatIf, once you're sure the operation will do what you want.
I'm currently trying to run a batch file as a startup script to detect and remove whatever version of office a user has installed and then to install Office 365. I have the install working however, when I attempted to uninstall Office 2013 I received the following error:
Input Error: Can not find script file "C:\Windows\OffScrub_O15msi.vbs"
The Offscrub file is in the same location as the script, is someone able to tell me why it's looking in C:\Windows for it?
Update
Please find my current script which now works for Office 2013, I previously added the line Remove2016Installs $true when using -Command to remove Office 2016, this worked. Since using -File to work around my initial problem I've been unable to get the script to remove Office 2016 and would like some advice on how to do this, I've read that whatever command is after -File needs to be the last which I believe might be why it's failing.
My full script is below:
start "----NOTICE----" cmd.exe /t:ec /Q /k "echo OFFICE 365 IS BEING INSTALLED. THIS WINDOW WILL CLOSE WHEN COMPLETE&&prompt $h"
#echo off
pushd "%~dp0"
powershell.exe -executionpolicy bypass -NoExit -File "Remove-PreviousOfficeInstalls.ps1"
popd
reg Query "HKLM\Hardware\Description\System\CentralProcessor\0" | find /i "x86" > NUL && set OS=32BIT || set OS=64BIT

There's a line that calls the Powershell script Remove-PreviousOfficeInstalls, this is a file from GitHub that is very popular for the removal of whichever Office version you have installed.
I can run this command if say I copy these files to the desktop and amend the locations in the scripts, I'm not sure what this reference to C:\Windows is though when run from \domain\SYSVOL\domain\Policies{Policy Number}\Machine\Scripts\Startup\?
If you run a default instances of PowerShell it always starts in a certain directory. It depends on how and who it is started by. For instance an administrative PowerShell usually starts in C:\Windows\System32. If you use any paths that are not absolute they're applied relative to this directory.
To work around this you need to change the directory it's using. For instance by using cd to change the directory. My guess would be that your script Remove-PreviousOfficeInstalls.ps1 contains a relative call to the VBS.
An easy fix would be to run a script block instead of a single command and just cd to \\domain\SYSVOL\domain\Policies\'{Policy Number}'\Machine\Scripts\Startup\ prior to running the ps1.
The PowerShell help you can view by following [this] link or running powershell -h has the following information in regards to using the -Command switch.
...
Script blocks must be enclosed in braces ({}). You can specify a script block only when running PowerShell.exe in PowerShell. If you want to use a script block when running from another shell you must use the format:
"& {}"
...
The other important parameter for your use case is -File.
Runs the specified script in the local scope ("dot-sourced"), so that the functions and variables that the script creates are available in the current session. Enter the script file path and any parameters.
...
Your batch contains the following line:
powershell.exe -executionpolicy bypass -Command "\\domain\SYSVOL\domain\Policies\'{Policy Number}'\Machine\Scripts\Startup\Remove-PreviousOfficeInstalls.ps1 -Remove2016Installs $true"
What you do is run a single command to invoke a script with a parameter. The problems is that said script checks its locations based on certain function and with your invocation that location is wrongly detected.
There are multiple ways to fix this. One would be to change the directory before invoking the script. To do this you'd need to use a script block as the parameter for -Command. An example for this would be:
powershell.exe -Command "& {Write-Output 'Hello'; Write-Output 'World';}"
As you can see there are two independent Write-Output commands being run. You'd change this to a cd \\domain\SYSVOL\domain\Policies\'{Policy Number}'\Machine\Scripts\Startup\ and the invocation of your script. As a bonus you wouldn't need to put the whole path in front of the script anymore.
The other option would be to run powershell -File with your current invocation of the script. That should also mean that the script is read from the file and the corresponding parameters are populated accordingly.
If neither of these options work you will have to check what $PSScriptRoot is being populated with and/or what the return of (Get-Item -Path ".\").FullName is as those are the two commands used to determine the location of the script that's being executed. To do this you could use a script block.
thanks for your help regarding this. My resolution was to use the following bat command:
`start "----NOTICE----" cmd.exe /t:ec /Q /k "echo OFFICE 365 IS BEING INSTALLED. THIS WINDOW WILL CLOSE WHEN COMPLETE&&prompt $h"`
#echo off
pushd "%~dp0"
powershell.exe -executionpolicy bypass -File Remove-PreviousOfficeInstalls.ps1 -Remove2016Installs
popd
reg Query "HKLM\Hardware\Description\System\CentralProcessor\0" | find /i "x86" > NUL && set OS=32BIT || set OS=64BIT
if %OS%==32BIT "\\Server\Folder\Folder\setup.exe" /configure "\\Server\Folder\Folder\configuration-Office365-x86.xml"
if %OS%==64BIT "\\Server\Folder\Folder\setup.exe" /configure "\\Server\Folder\Folder\configuration-Office365-x64.xml"
taskkill /IM cmd.exe /FI "WINDOWTITLE EQ ----NOTICE----"
taskkill /IM cmd.exe /FI "WINDOWTITLE EQ Administrator: ----NOTICE----"
echo %date% %time% Setup ended with error code %errorlevel%. >> %LogLocation%\%computername%.txt
I had to amend the Remove-PreviousOfficeInstalls powershell script to include the switch command:
[Parameter(ValueFromPipelineByPropertyName=$true)]
[switch]$Remove2016Installs = $false,
This then did exactly what I was after, it detected the current version of Office, removed it and installed the correct bit version of Office 365 for that PC\Laptop.
Thanks for all your help
for /f "tokens=1-7 delims=,: " %a in ('query user ^| find /i "disc"') do logoff %b
This above code is used for logoff remote desktop users where state is "Disconnected" in windows 2003.It will work perfect when I run in command prompt. But it will not run when I made a .bat file or .cmd file in windows 2003.so may know where i am going wrong?
Inside batch files the percent signs used in the for replaceable parameters need to be escaped
for /f "tokens=1-7 delims=,: " %%a in ('query user ^| find /i "disc"') do logoff %%b
User585,
Yes, inorder to implement the for loop inside a bat/cmd session, you need to place the variable with
%%a
like this
for /f %%a in (.\hosts) do quser /server:\\%%a
I need to run a simple command line within teamcity
FINDSTR /M /N /P /S /R /C:"goto end" D:\blabla\*
The double quote are replaced and somehow doubled when teamcity calls the command. The resulting command is
cmd.exe /c FINDSTR /M /N /P /S /R "/C:"goto end""
Which fails.
How can I prevent this from happening? The value for param /C requires a param with double quotes in my case. thanks
Put your command in a batch file and call that passing in whatever arguments (if any) you need.
Whenever you do anything like this on windows, always do this :)
Your example:
FINDSTR /M /N /P /S /R /C:"goto end" D:\blabla\*
Works as-is, in TeamCity 2018.1.3, using a Command Line runner with the above specified in the Custom Script section.
I have a path in variable (script parameter) %2.
I need to do the following:
Extract the leaf (last folder from the path) to a variable.
Run the following command: robocopy %2 \\somepath\%leaf
I was told this could be done in PowerShell (cause I've tried going with batch file alone and failed miserably) Here's a pseudocode representation of what I'd like to achieve:
set leaf = powershell -command (split-path %2 -leaf)
robocopy %2 \\somepath\%leaf
Any idea how to write this correctly?
Thank you.
Whenever you want to set a batch variable to the output of a command, use for /f. Here's an example:
#echo off
setlocal
set "psCommand=powershell -command "(split-path '%~2' -leaf)""
for /f "delims=" %%I in ('%psCommand%') do set "leaf=%%I"
echo %leaf%
But this is a terribly inefficient way to retrieve the last folder of a path. Instead of invoking PowerShell, what you should do is this:
#echo off
setlocal
for %%I in ("%~2") do set "leaf=%%~nxI"
echo %leaf%
The %%~dpnxI notation gets
d = drive
p = path
n = name
x = extension
It's traditionally intended for files, rather than directories; but it works just as well for directories anyway. See the last couple of pages of for /? in a console window for complete details.
FOR %%a IN ("%~2") DO FOR %%b IN ("%%~dpa.") DO ECHO %%~nxb
Batch one-liner. Take the parameter (second parameter here), remove any quotes and re-apply them. Select the drive and path, add '.' then select the name and extension of the result making leaf required.
Obviously, if you require this in a variable,
FOR %%a IN ("%~2") DO FOR %%b IN ("%%~dpa.") DO set "leaf=%%~nxb"
