Using SysInternals Live or PowerShell: Install‑SysInternals.ps1

Below is a PowerShell script to deploy (or remove) the entire SysInternals Suite on your Windows systems—perfect for automation in RMM or other deployment frameworks.

# SYNTAX: .\Install-SysInternals.ps1 [-Uninstall] (Run as Administrator)
# Learn more: https://docs.microsoft.com/sysinternals
<#
.SYNOPSIS
    Downloads, installs, or uninstalls the Sysinternals Suite as a standalone PowerShell script.

.DESCRIPTION
    - Without parameters, the script downloads the latest Sysinternals Suite ZIP directly from Microsoft,
      extracts it to "%ProgramFiles%\Sysinternals", and ensures the folder is in the system PATH.
    - With the -Uninstall switch, it removes the installation folder and cleans up the PATH.

.PARAMETER Uninstall
    Switch parameter. If present, the script uninstalls the Sysinternals Suite by deleting the
    installation folder and removing its entry from the system PATH.

This script:

When you run Install-SysInternals.ps1 (without -Uninstall), here’s exactly what happens step-by-step:

Download
Invoke-WebRequest –Uri $downloadUrl –OutFile $tempZip
The script fetches the latest SysinternalsSuite.zip directly from Microsoft and saves it into your %TEMP% folder.
Remove any existing install
if (Test-Path $installDir) { Remove-Item $installDir –Recurse –Force }
If you already have a “C:\Program Files\Sysinternals” folder, it deletes it completely—so you always get a fresh install.
Create the installation folder
New-Item –Path $installDir –ItemType Directory
Makes a clean directory at “C:\Program Files\Sysinternals”.
Extract the ZIP
Expand-Archive –Path $tempZip –DestinationPath $installDir –Force Remove-Item $tempZip –Force
Unzips every Sysinternals executable (like PsExec, Process Explorer, Autoruns, etc.) into that folder, then deletes the temporary ZIP.
Update your system PATH
Add-ToPath –PathToAdd $installDir
Appends “C:\Program Files\Sysinternals” to your machine-wide PATH environment variable so you can just type e.g. procexp at any command prompt. This will not create a duplicate if it is already there.

Importantly: the script does not launch or run any of the Sysinternals tools itself—it merely places the binaries on disk and makes them globally callable. If you want to execute a tool (for example, Process Explorer), you would run it yourself after installation in an administrative Command or PowerShell prompt:

procexp.exe

Or use the Sysinternals Live feature:

\\live.sysinternals.com\tools\procexp.exe

Final Thoughts: Automate, Secure and Supercharge with AI

By pairing SysInternals Live with automated PowerShell deployment, we ensure that your entire team always has the latest troubleshooting tools at their fingertips—without manual downloads and with consistent configurations.

Supercharge SysInternals with AI:

Automated Anomaly Detection
- Feed Sysinternals output (Process Explorer logs, CPU/Disk metrics, Autoruns snapshots) into an AI model (e.g. Azure Copilot/ML, Claude, ChatGPT).
- Use unsupervised learning (autoencoders, clustering) to detect outliers—unexpected processes, spikes, or new auto-start entries.
- Alert on deviations from learned “normal” baselines.
Intelligent Incident Triage
- Integrate PSExec, PSLogList or ProcMon logs into an AI pipeline that classifies event severity.
- NLP on event descriptions to automatically generate incident tickets with prioritized summaries and suggested remediation steps.
Predictive Maintenance
- Aggregate performance counters (CPU, memory, I/O) collected via PsInfo or Performance Monitor alongside historical failure data.
- Train time-series forecasting (LSTM, Prophet) to predict disk failures, resource exhaustion, or service crashes before they occur.
Automated Remediation Playbooks
- Pair AI decision engines with PSExec and PowerShell scripts: when AI flags a malicious or runaway process, automatically execute containment (e.g. kill process, quarantine file) via Sysinternals tools.
- AI can learn which remediation steps historically resolved similar incidents, then execute the optimal playbook.
Enhanced Threat Hunting
- Use Autoruns and Sigcheck outputs as features in a machine-learning classifier trained on known-good vs. malicious binaries.
- Detect suspicious file versions, unsigned executables, or anomalous persistence mechanisms.
Natural-Language Troubleshooting Assistant
- Build a chatbot (using GPT or Azure OpenAI) that ingests Sysinternals outputs and answers questions like “Why is CPU at 90%?” or “Show me newly installed auto-start entries this week.”
- The bot can parse logs, correlate events, and suggest next steps in plain English.
Dashboarding and Visual Insights
- Stream Sysinternals data into a data lake, then use AI-driven visualization tools (Power BI with AI visuals) to surface hidden trends—e.g., which processes most often precede service outages.

Next Steps: Incorporate this script into your Remote Management & Monitoring (RMM) policies, and schedule regular runs of Sysmon for continuous security monitoring.

Getting Started

Schedule regular Sysinternals exports (via Task Scheduler + PowerShell).
Normalize outputs into JSON or CSV.
Prototype simple models in Python (pandas + scikit-learn or Azure ML).
Gradually automate alerts and remediation through PowerShell/PSExec integration.

By combining Sysinternals’ deep Windows insight with AI’s pattern-recognition and automation capabilities, you’ll transform raw diagnostic data into proactive, self-healing IT operations.

Happy automating and securing!
