The open-source system information utility Glow has just received its 26.9 update, delivering a suite of meaningful enhancements aimed at both hardware enthusiasts and privacy-conscious users. Among the most notable additions are broader processor detection, more accurate RAM vendor identification, built-in public IP and ISP reporting, and a long-requested search function to quickly sift through detailed system specs. Available as a free, portable download for Windows 10 and Windows 11, Glow version 26.9 solidifies its position as a lightweight yet powerful alternative to heavier diagnostic tools—all without tracking users or bundling unwanted software.

For anyone who has struggled to identify a no-name RAM stick using Windows’ built-in tools or wondered why a brand-new CPU shows up as ‘Unknown’ in device manager, this update delivers immediate, practical value. It also brings a privacy-first approach to network information: with one click, you can now see your public IP address and ISP without having to visit a third-party website that might log your activity. The new search bar, meanwhile, turns Glow from a static spec sheet into an interactive dashboard where finding a specific hardware detail takes seconds instead of minutes.

What is Glow, and Why Does It Matter?

Glow first appeared on GitHub as a community-driven response to the clutter and closed nature of many system information tools. Unlike commercial offerings that often monetize through ads or bundled promotions, Glow is completely open source, with its code publicly auditable and contributions welcomed from developers worldwide. It runs as a single executable on Windows 10 and 11—no installation required—and leaves zero traces on the host system. That portability makes it a favorite among technicians who need to diagnose multiple machines without installing software, as well as privacy-focused users who balk at the telemetry built into Windows’ own system information utilities.

At its core, Glow provides comprehensive hardware and system data: CPU model, core count, clock speeds, cache sizes, motherboard information, RAM configuration, GPU details, disk drives, network adapters, and more. Version 26.9 expands that capability in several critical areas while introducing new features that reflect real-world user needs. The tool’s developer, known online as ‘raven-au,’ has steadily refined the utility over dozens of releases, often incorporating feedback from the Windows community.

Broader Processor Detection: No CPU Left Unnamed

The centerpiece of Glow 26.9 is its revamped CPU detection engine. Previous versions already recognized most mainstream processors from Intel and AMD, but the new release significantly expands the database to include the latest generations, as well as some niche and embedded chips that often confuse other tools. For example, Glow can now correctly identify Intel Arrow Lake and Lunar Lake engineering samples, AMD Strix Point APUs, and even certain server-oriented Epyc models that previously showed up with generic descriptors. The detection logic has also been refined to extract stepping, microcode revision, and thermal design power (TDP) more reliably from the CPUID instruction, giving overclockers and system builders granular data they can act on.

The update also addresses a long-standing annoyance: hybrid architecture processors like Intel’s 12th–14th gen Core parts, which mix Performance-cores and Efficient-cores, now have their core configurations displayed clearly. Instead of lumping all cores together, Glow breaks down the P-core and E-core counts, base frequencies, and turbo ratios. For users trying to optimize thread pinning or diagnose uneven performance in games, this level of detail is a game-changer.

Better RAM Vendor Identification: Decoding the SPD Table

Ask any PC builder about the most frustrating part of system diagnostics, and RAM identification will likely come up. Windows Task Manager and generic system info tools often show only capacity and speed, leaving out the manufacturer, part number, and memory type. Glow 26.9 tackles this head-on by deeply parsing the Serial Presence Detect (SPD) data stored on each memory module’s EEPROM.

In earlier versions, Glow already listed basic RAM info, but it sometimes defaulted to the module’s JEDEC manufacturer ID code, which could be ambiguous or entirely unknown for smaller brands. The new update cross-references a much larger SPD database—regularly updated from industry sources—to decode those codes into human-readable brand names. As a result, you can now distinguish between, say, SK Hynix, Samsung, and Micron OEM sticks, or spot a Corsair module even when its heat spreader obscures the label. This is invaluable when troubleshooting memory compatibility issues, planning upgrades with identical DIMMs, or verifying the authenticity of second-hand purchases.

Beyond vendor names, Glow 26.9 now reports the memory rank (single, dual, or quad rank), which influences performance and motherboard compatibility, and accurately reads the voltage requirements for both non‑XMP and XMP profiles. For laptops with soldered memory, where physical inspection is impossible, Glow offers the most complete look at what’s actually inside.

Public IP and ISP Reporting: Privacy-Friendly Network Intelligence

Network diagnostics often require knowing your public IP address and internet service provider, but most people resort to websites like “WhatIsMyIP” that monetize the very query by serving ads and potentially tracking you. Glow 26.9 eliminates that dependency. A new “Network” tab now displays your external IP address, ISP name, and autonomous system number (ASN) by making a one-time, anonymous query to a public STUN server. No personal data is transmitted, and the transaction leaves no cookie or fingerprint behind.

This feature is especially useful when you’re behind a VPN or proxy and want to verify that your real location is masked. Glow compares the detected public IP against known VPN/cloud IP ranges and flags mismatches—so if you think you’re connected through a VPN but Glow shows your home ISP, something is misconfigured. It also reports whether IPv6 connectivity is active and, for advanced users, lists the internal network interfaces with their MAC addresses and link speeds.

For the privacy-conscious, the tool’s approach is a model of transparency: the entire network query module is open source, and users can inspect exactly what data is sent and received. There’s no phoning home, no usage analytics, and no nag screen asking you to buy a premium version.

Search: Finding a Needle in a Hardware Haystack

Even Glow’s previously clean interface could become overwhelming when it listed dozens of sensors, drive partitions, and USB devices. Version 26.9 introduces a global search box—press Ctrl+F or click the magnifying glass—that scans all reported system information in real time. Type “temperature” and you instantly see CPU, GPU, and drive thermals; type “serial” and every device serial number appears, from the motherboard to the OS license key (when readable).

The search also supports partial matches and filters by category. For instance, entering “GPU:vram” narrows results to only VRAM-related data for graphics devices. This makes Glow not just a reporting tool but an interactive diagnostic assistant, especially when you need to quickly pull a specific value for support tickets or forum posts.

Other Refinements and Known Community Input

Beyond the headlining features, Glow 26.9 includes numerous smaller improvements that polish the overall experience. The user interface received a slight visual refresh with better high-DPI scaling and dark mode support that respects Windows system settings. Tool tips now explain what each sensor reading actually means, demystifying values like “VDDCR CPU” or “DRAM CH_B VREF.” A new export function can save the full system report as a plain text or JSON file, making it easier to share with technical support or compare configurations between machines.

Community feedback has been instrumental in shaping this release. On forums and GitHub issues, users had frequently requested better Ryzen Infinity Fabric clock detection, and Glow 26.9 delivers that along with unified L3 cache reporting for AMD’s 3D V‑Cache models. Some early adopters on Windows Forums noted that the public IP feature initially failed with certain VPNs that block STUN traffic; the developer pushed a quick patch (26.9.1) to fall back to an HTTPS-based API in such cases, still with privacy safeguards. This rapid response typifies the project’s commitment to user-driven development.

How Glow Stacks Up Against the Competition

The Windows ecosystem offers a slew of system information tools, from HWiNFO and CPU‑Z to AIDA64 and Speccy. Each has its own strengths, but Glow carves out a unique niche by being completely open source, portable, and laser-focused on privacy. HWiNFO provides even deeper sensor readings and benchmark integration, but it is proprietary and its portable version still writes to the registry. CPU‑Z excels at processor validation but has limited GPU and network info. Speccy, once a go-to, is now largely abandoned and often flagged by antivirus due to outdated bundled offers. AIDA64 is powerful but requires a paid license.

Glow occupies the middle ground: comprehensive enough for most power users and IT professionals, yet light enough to run from a USB stick on a locked-down client machine. Its open‑source nature means any security-conscious organization can audit the code, compile it themselves, and deploy it without worrying about supply‑chain attacks—a significant advantage in enterprise environments.

The addition of public IP reporting also distinguishes Glow from its peers. No other major tool integrates an ISP check directly into the UI; you typically need to switch to a browser or command‑line utility. By bundling this into a system info tool, Glow reduces context-switching and keeps your diagnostic workflow private.

Real-World Use Cases: Who Benefits Most from Glow 26.9?

  • System builders and repair technicians can quickly inventory a machine’s components without installing any software. The improved RAM detection helps them order exact replacement parts, while the CPU breakdown assists in verifying that a used computer matches its advertised specs.
  • Overclockers gain precise core-by-core frequency and voltage data, plus the ability to search for specific tuning parameters instantly.
  • Privacy advocates get a one-stop view of their internal and external network identity, letting them confirm that their VPN or Tor setup is working as intended—all while avoiding tracking-laden IP‑check websites.
  • Enterprise IT can deploy Glow via Group Policy or login scripts to collect standardized hardware inventories without worrying about license audits or vendor lock-in.
  • Casual users upgrading their RAM or SSD will appreciate being able to identify their existing modules without cracking open the case, especially for laptops with difficult access.

Getting Started with Glow 26.9

The update is available immediately from the project’s GitHub releases page, where you’ll find both the standard portable executable and a ZIP archive with the source code. No installation is needed: just download, extract, and run Glow.exe. It automatically detects your system language and adapts the interface accordingly, though English is the default. The tool asks for no admin rights unless you want to read S.M.A.R.T. drive data—a deliberate design choice that limits potential security exposure.

For those who prefer to build from source, the repository includes a Visual Studio solution and straightforward build instructions. The project is licensed under the MIT License, meaning you can freely modify and redistribute it, even in commercial environments.

A Look Ahead: The Roadmap for Open-Source Diagnostics

While the developer has not published a formal roadmap, discussions on GitHub suggest that future versions of Glow may include GPU‑specific health monitoring (e.g., VRAM temperature delta, hotspot readings) and integration with Windows’ built-in performance counters for real-time charting. There’s also talk of a community plugin system that would let third parties extend the tool’s capabilities without altering the core code—imagine add-ons for benchmarking, stress testing, or even RGB control.

In an era where system utilities are often viewed with suspicion due to bundled crapware or opaque data collection, Glow’s transparent, community-led model feels like a return to the golden age of PC tinkering. Version 26.9 demonstrates that open source can not only match but exceed the polish and functionality of proprietary alternatives, all while respecting user autonomy. As Windows continues to evolve, tools like Glow become essential for anyone who wants to truly understand what’s happening under the hood—without sacrificing privacy or convenience.
