How to Silently Install WinDirStat

Get a reliable rollout and predictable detection for WinDirStat with a packaging approach built for enterprise deployment. This guide is aimed at IT admins who need a straightforward way to deploy the machine-wide MSI with admin rights while keeping installs consistent across endpoints. It focuses on using the verified silent install command, validating detection rules, and reducing deployment friction when distributing WinDirStat through Intune, SCCM, or PDQ.

msiexec /i "WinDirStat.WinDirStat.2.6.2.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1

Overview

Silent install steps

Run any one of the methods below to install WinDirStat silently with zero user interaction. Command Prompt and PowerShell produce the same result — use whichever fits your deployment workflow.

Method 1: Install with Command Prompt

1. Download or stage the installer (WinDirStat.WinDirStat.2.6.2.X64.msi) to a local folder, for example C:\Installers.

2. Open Command Prompt as Administrator:
   Press Start→Type cmd→Right-click Command Prompt→Choose Run as administrator

3. Switch to the installer folder, then run the silent install command:

msiexec /i "WinDirStat.WinDirStat.2.6.2.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1

C:\> cd /d "C:\Installers"C:\Installers> msiexec /i "WinDirStat.WinDirStat.2.6.2.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1Installing WinDirStat 2.6.2…100%Installation complete — exit code 0.C:\Installers> ▋

Method 2: Install with PowerShell

Run the same silent install through PowerShell (elevated).

1. Download or stage the installer (WinDirStat.WinDirStat.2.6.2.X64.msi) to a local folder, for example C:\Installers.

2. Open PowerShell as Administrator — right-click Start (or press Win+X), then:
   • On Windows 10: choose Windows PowerShell (Admin).
   • On Windows 11: choose Terminal (Admin) — it opens Windows Terminal running PowerShell.

3. Run the command:

Start-Process -FilePath "msiexec.exe" -ArgumentList '/i "WinDirStat.WinDirStat.2.6.2.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1' -Wait -NoNewWindow

PS C:\> Set-Location 'C:\Installers'PS C:\Installers> Start-Process -FilePath "msiexec.exe" -ArgumentList '/i "WinDirStat.WinDirStat.2.6.2.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1' -Wait -NoNewWindowInstalling WinDirStat 2.6.2…100%Installation complete — exit code 0.PS C:\Installers> ▋

Deployment Notes

Key facts to confirm before rolling this out to production machines — permissions required, scope of install, and reboot behavior.

Detection Rules

Configure your deployment tool with the detection rule below to confirm a successful install of WinDirStat. The same rule work for Microsoft Intune, SCCM, PDQ Deploy, and most RMM platforms — just paste the values into the matching fields.

MSI product code detection

PowerShell detection script

Prefer a script-based check? Use this as a custom detection script in Microsoft Intune (or any tool that supports detection scripts). It exits 0 when WinDirStat is detected and 1 otherwise.

$Code = '{7B2660BD-6B99-4BFE-8FA7-43B2BA839761}'
$Paths = @(
    "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\$Code",
    "HKLM:\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\$Code"
)
if ($Paths | Where-Object { Test-Path $_ }) { exit 0 }
exit 1

Silent Uninstall Steps

Remove WinDirStat silently from one machine or your entire fleet. The commands below uninstall without prompts and suppress automatic reboots so you control the timing.

Method 1: Uninstall with Command Prompt

Run the uninstall command from an elevated Command Prompt.

1. Open Command Prompt as Administrator.
2. Run the silent uninstall command.

msiexec /x "{7B2660BD-6B99-4BFE-8FA7-43B2BA839761}" /qn REBOOT=ReallySuppress

Method 2: Uninstall with PowerShell

Run the same silent uninstall command through PowerShell.

1. Open PowerShell as Administrator.
2. Run the silent uninstall command.

Start-Process -FilePath "msiexec.exe" -ArgumentList '/x "{7B2660BD-6B99-4BFE-8FA7-43B2BA839761}" /qn REBOOT=ReallySuppress' -Wait -NoNewWindow

Deployment Examples

Drop one of the snippets below into your deployment tool, Group Policy, or scheduled task. Each script wraps the silent install command for WinDirStat as a batch file or PowerShell script — copy, save, and run.

Batch file example

Save the following content as install-windirstat.bat in the same folder as the installer.

@echo off
cd /d "%~dp0"
msiexec /i "WinDirStat.WinDirStat.2.6.2.X64.msi" /qn REBOOT=ReallySuppress ALLUSERS=1
exit /b %errorlevel%

PowerShell script example

Save the following content as install-windirstat.ps1 in the same folder as the installer.

Set-Location -Path $PSScriptRoot
$Installer = 'WinDirStat.WinDirStat.2.6.2.X64.msi'
& msiexec.exe /i $Installer /qn REBOOT=ReallySuppress ALLUSERS=1
exit $LASTEXITCODE
