Sysinternals turned 30 this year and Microsoft still ships it as a manual download that never lands in Windows 11 by default. Process Explorer, Autoruns, TCPView, and RAMMap have kept the same 2005-era UI while the rest of the OS moved on. That gap is why the tools below exist. Every Sysinternals alternative here fixes a specific limitation we hit when running the original suite on a modern Windows 11 install.
We spent a week rebuilding a Sysinternals workflow from scratch using open-source and freeware replacements. Some pieces (like Process Explorer) have peers that surpass the original. Others (like Autoruns) are harder to replace outright. This article covers what actually swaps in cleanly, what still needs Microsoft’s tools, and which combinations reproduce a full power-user toolkit.

Why people leave Sysinternals
The original toolkit works, and Mark Russinovich still ships updates. But the practical friction is real. Three complaints keep surfacing on r/sysadmin and Hacker News.
The UI is frozen in 2005. Process Explorer’s icons, layout, and dialog spacing predate DPI scaling. On a 4K monitor at 150% scale, half the buttons overflow and toolbar text clips. There is no dark mode, no accent color inheritance, and no filter-as-you-type in most tools.
There is no installer, no updater, and no channel. You download a ZIP, unblock the exe, and remember to check for updates yourself. That is fine for one workstation, painful across a fleet. Sysinternals Live works as a runner but breaks in offline or air-gapped environments.
Some tools have obvious gaps. RAMMap does not export. Autoruns has no VirusTotal scoring by default. TCPView cannot chart bandwidth over time. Handle is command-line only. The alternatives below either fill those gaps or replace the tool outright with something that solves them.
The alternatives
System Informer — Best overall Process Explorer + Process Monitor replacement
System Informer (formerly Process Hacker) is the closest thing to a modern Sysinternals rewrite. It handles what Process Explorer, Process Monitor, and Handle do, plus a service manager and a network monitor. The kernel driver lets it inspect protected processes and read memory that Task Manager cannot touch.
The UI supports dark mode, per-column filtering, and a scriptable plugin API. Tree view for process ancestry works out of the box, and CPU history graphs go per-thread when you drill in.
Where it falls short: No direct equivalent to Process Monitor’s boot-time trace, and the log format is different so existing PML files do not import.
Pricing:
- Free: Full-featured, no tiers
- Paid: None
- vs Sysinternals: Same price (free), meaningfully more modern
Migrating from Sysinternals: Process Explorer keybindings and column choices don’t carry over, but the layout is close enough that muscle memory adapts in a day. Process Monitor filter files (.pmc) don’t import, but System Informer’s own filters cover the same fields.
Download: System Informer
Bottom line: Install this first. It replaces the two Sysinternals tools most people actually use, and adds features Microsoft never shipped.
NirSoft Suite — Best for one-off tasks and forensic work
NirSoft publishes 250+ single-purpose utilities that overlap heavily with the Sysinternals surface area. CurrPorts covers TCPView. ProcessActivityView covers Process Monitor. WhatInStartup covers Autoruns. NK2Edit reads Outlook autocomplete files. There is a tool for almost every “how do I inspect this exact Windows thing” question.
Nir Sofer has maintained the collection since 2001, and each utility is a single small exe with no dependencies. That makes NirSoft the go-to for portable forensics: drop the folder on a USB stick and every tool runs.
Where it falls short: No unified launcher, so remembering which utility does what takes time. Some tools are Windows-XP-era in appearance. Antivirus flags a few of them because password-recovery utilities look like malware.
Pricing:
- Free: All utilities, no tiers
- Paid: None
- vs Sysinternals: Comparable, wider coverage but shallower per tool
Migrating from Sysinternals: No import path. Each NirSoft tool is standalone. The NirLauncher wrapper gives you a searchable index if you want one interface across all 250.
Download: NirSoft
Bottom line: Keep this on your admin USB. When you need to answer a weird Windows question fast, someone at NirSoft usually already wrote the tool.
HWiNFO — Best for hardware sensor detail
Sysinternals never covered hardware sensors. HWiNFO does, and it does more of it than any competing tool. Read CPU package temperatures per core, per-VRM voltages, GPU hotspot temps, NVMe drive-write endurance, and DIMM thermals. Logging runs down to 1-second intervals into CSV, which is enough resolution for thermal throttling analysis.
The sensor coverage is broad because HWiNFO reads directly from motherboard EC and SMBus rather than only WMI. That means it picks up sensors most tools miss.
Where it falls short: The UI shows everything at once and can be overwhelming. Free is personal-use only; commercial licenses cost extra.
Pricing:
- Free: Personal use, full features
- Paid: About $30/year commercial per seat
- vs Sysinternals: Complementary rather than replacing anything
Migrating from Sysinternals: No overlap to migrate. This fills a gap Sysinternals never covered.
Download: HWiNFO
Bottom line: If you diagnose thermal, power, or memory issues on real hardware, this is the tool. Sysinternals users who run Windows on laptops or workstations get the biggest lift.
GlassWire — Best for network monitoring with charts
TCPView shows current connections. GlassWire shows current connections plus a five-minute-to-multi-year traffic graph broken down by process, host, and country. If someone asks “why is my machine chatty at 3 AM,” GlassWire answers it in one screen. TCPView requires you to be watching at the right moment.
The firewall integration lets you block per-app in one click, and alerts fire on new hosts, new applications, or unexpected traffic spikes.
Where it falls short: The pro tier gates the longer history window and the more useful alerts. The free tier resets the graph on reboot.
Pricing:
- Free: Basic monitoring, current session only
- Paid: About $3/mo for Basic, $5/mo for Pro
- vs Sysinternals: Paid features beat TCPView; free tier is roughly equivalent
Migrating from Sysinternals: TCPView filter columns don’t carry over, but the metaphor is the same (process to remote host with counts).
Download: GlassWire
Bottom line: Pick this if you want visualization and history, not just a live table. Free tier is fine for spot checks; pay for the alerting.
Everything — Best Sigcheck / file search replacement
Sysinternals Sigcheck is a command-line tool for finding files. Everything by voidtools does the same job with an instant GUI. It indexes the entire NTFS Master File Table on first run (usually under a minute for a 1TB SSD) and answers filename queries in real time as you type.
Regex support, exclude patterns, and per-column sort all work. There is also an HTTP server mode for searching a machine remotely and an ETP protocol for LAN-wide search.
Where it falls short: NTFS only. FAT32 or exFAT drives fall back to a slower scanning mode. Content search inside files is a plugin, not built in.
Pricing:
- Free: Full features
- Paid: None
- vs Sysinternals: Free, faster, better UI
Migrating from Sysinternals: No import path. Command-line users can use es.exe (the CLI wrapper) for scriptable queries.
Download: Everything
Bottom line: Every Windows machine should have this. Sysinternals Sigcheck users get most of what they need plus a UI.
WizTree — Best RAMMap-adjacent disk usage tool
Sysinternals RAMMap shows physical memory usage. WizTree does the disk equivalent: read the NTFS MFT directly and show you what is taking space, ranked by folder, file, or file type. A 4TB drive scans in about 10 seconds.
The treemap view visualizes clusters of large files at a glance. Filter by extension to find every media file, every log, every crash dump on a system.
Where it falls short: NTFS-only for fast scans; ReFS and non-Windows filesystems fall back to slow mode. Free tier limits some export options.
Pricing:
- Free: Full scan and view
- Paid: About $12 one-time for Pro (adds export and CLI)
- vs Sysinternals: Free, and Sysinternals never had this tool
Migrating from Sysinternals: No overlap. WinDirStat users will feel at home immediately.
Download: WizTree
Bottom line: Faster than WinDirStat, quieter UI. Use it whenever a drive fills up unexpectedly.
Autoruns Organizer — Best Autoruns replacement with VirusTotal built in
Sysinternals Autoruns is the reference tool for finding what launches at boot, but it does not integrate VirusTotal by default. Autoruns Organizer covers the same startup entries (services, scheduled tasks, shell extensions, drivers, DLLs) and scores each entry against VirusTotal automatically, with severity coloring.
The interface is faster to filter than Autoruns and remembers your view preferences across sessions.
Where it falls short: Fewer categories than the full Autoruns list. Some obscure hive locations aren’t scanned. Pro tier adds silent scanning and reporting.
Pricing:
- Free: Basic startup management
- Paid: About $25/year for Pro
- vs Sysinternals: Free tier matches Autoruns core; paid tier adds automation
Migrating from Sysinternals: Autoruns backup files (.arn) don’t import, but the categories map one to one.
Download: Autoruns Organizer
Bottom line: Use this on any machine you suspect of adware or unwanted startup entries. VirusTotal scoring saves the copy-paste step Autoruns forces on you.
How to choose
Pick System Informer if you spend most of your Sysinternals time in Process Explorer or Process Monitor. It is the direct upgrade, dark mode included, and the kernel driver matches what the original tools do.
Pick NirSoft Suite if you want the widest tool coverage on a USB stick for forensics or emergency triage. No installer, no dependencies, works on any Windows.
Pick HWiNFO if you need hardware sensor detail Sysinternals never touched. Thermal analysis, power draw, drive wear tracking.
Pick GlassWire over TCPView if you want the network history to persist through reboots. Free is enough for spot checks; pay for alerts.
Stay on Sysinternals for Process Monitor boot-time traces, Handle command-line output for scripts, and the PsTools remote execution suite. Those still don’t have a clean single-tool replacement.
FAQ
Is System Informer safe to install? Yes. It is open source (BSD-3 license), signed, and audited. The kernel driver requires administrator install because that is how it inspects protected processes, same as Process Explorer.
Can I use Sysinternals alternatives on Windows Server? System Informer, NirSoft, HWiNFO, Everything, and WizTree all run on Windows Server 2016 and later. GlassWire and Autoruns Organizer target desktop editions but usually work on Server with minor UI quirks.
What is the best free Sysinternals alternative? System Informer for process work, NirSoft for one-off utilities, Everything for file search. All three are free with no paid tier. Together they cover about 80% of what most people actually use Sysinternals for.
Why isn’t there a full one-tool Sysinternals replacement? Sysinternals is a collection built over 30 years across process, autostart, network, memory, disk, and command-line domains. No single project has taken on all of that surface area. The alternatives here work best in combination.
Do these alternatives work in enterprise environments with SmartScreen and Defender? System Informer, HWiNFO, Everything, WizTree, and Autoruns Organizer are signed and reputation-cleared. NirSoft tools sometimes trigger antivirus heuristics because password-recovery utilities look like malware. Whitelist per site policy.
