A stubborn late‑model PC and a patient tinkerer have done what many considered impossible: coaxing modern Steam and Team Cherry’s hotly anticipated Silksong to run on a machine still sitting on Windows 7. The spectacle is less about raw performance than it is a reminder that the PC ecosystem—its games, platform clients, drivers and energetic communities—can be bent, bridged, and sometimes bullied into cooperation. The episode touches on bigger issues: platform support lifecycles, the fragility of official compatibility guarantees, and the dedicated ingenuity of hobbyist modders who keep legacy systems alive long after vendors move on.
Windows 7 is officially ancient by OS standards: Microsoft ended mainstream support years ago, and security patching for consumer editions ceased in January 2020. Despite that, many users clung to the OS for familiarity, performance on older hardware, or because their workflows simply worked. Valve’s Steam client continued to support Windows 7 for a long tail, but in 2023 Valve confirmed it would end formal support for Windows 7, 8 and 8.1 effective January 1, 2024—leaving any continued use of the platform on those OSes unofficial and unsupported.
Team Cherry’s Hollow Knight: Silksong is a comparatively light‑weight 2D Unity title whose published minimums have historically been modest; the Steam store lists Windows 7 compatibility in its minimum requirements for the PC build. That low bar made Silksong a plausible candidate for a legacy‑OS run—on paper, at least.
What unfolded was a multi‑stage engineering workaround: forcing a now‑unsupported Steam client to start, bypassing modern download/validation blocks, moving game files from a modern machine, and applying community kernels and runtime patches to supply missing functionality on Windows 7. The result was not merely a slideshow—Silksong booted and played, including progression past an early boss encounter—on hardware and drivers that would be laughable by today’s standards.
The community response to support cutoffs is predictable and powerful. Projects, scripts, and modders appear to fill practical gaps: lightweight installer images, kernel extenders, runtime redistributables, patched drivers, and manual workarounds. These projects are not sanctioned, and they are far from risk‑free, but they give users agency. Tiny builders that prune modern Windows images to remove mandatory checks, unofficial drivers that restore dropped functionality, and creative file copying tactics are all part of a thriving ecosystem that counters forced obsolescence. Our archives of community discussion show that these efforts are widespread and ongoing; they’re a social and technical safety valve when vendor policies change.
This dynamic reveals two truths: 1) official support windows matter because they anchor long‑term security and compatibility; and 2) the tinkerer community will often keep older machines useful long after official support ends—sometimes at the cost of convenience or safety.
But the headline spectacle should not mask the practical truth: these setups are complex, brittle, and insecure by default. The community’s ingenuity keeps old systems alive and teaches valuable lessons about modularity and software design. What it cannot substitute for, however, is the ongoing security maintenance an OS vendor provides. In short: applaud the feat, admire the craft, but if your files or finances depend on the machine, choose a supported path.

Background / Overview
Windows 7 is officially ancient by OS standards: Microsoft ended mainstream support years ago, and security patching for consumer editions ceased in January 2020. Despite that, many users clung to the OS for familiarity, performance on older hardware, or because their workflows simply worked. Valve’s Steam client continued to support Windows 7 for a long tail, but in 2023 Valve confirmed it would end formal support for Windows 7, 8 and 8.1 effective January 1, 2024—leaving any continued use of the platform on those OSes unofficial and unsupported.

The result was not merely a slideshow—Silksong booted and played, including progression past an early boss encounter—on hardware and drivers that would be laughable by today’s standards.
Why this matters: support lifecycles and the hobbyist counterweight
Microsoft and Valve make platform decisions for defensible reasons: security, maintainability, and modern feature dependencies. When a platform component (for example, the embedded Chromium used inside Steam) drops compatibility with older OSes, the vendor is forced to push forward. Valve’s decision to stop updating Steam on Windows 7/8/8.1 was framed as necessary because core Steam functionality relies on an embedded browser that no longer works on those OSes; as a result the client will not receive updates or official technical help on those platforms. That’s a clear, industry‑standard trade‑off—but it leaves the possession of otherwise functional hardware at the mercy of compatibility churn.The community response to support cutoffs is predictable and powerful. Projects, scripts, and modders appear to fill practical gaps: lightweight installer images, kernel extenders, runtime redistributables, patched drivers, and manual workarounds.

The technical story — how Silksong was made to run on Windows 7
1. Getting Steam to boot on an unsupported OS
- The Steam client stopped being updated on Windows 7 as of January 1, 2024, meaning modern Steam builds can refuse to run, show nagging warnings, or fail at run‑time checks. Vendors sometimes embed explicit OS checks in the client to avoid unsupported usage.
- The reported method in this case involved manual manipulation inside the Steam installation to remove or neutralize the modules that prevented startup—basically, surgical deletion or renaming of a couple of DLLs that performed the OS sanity checks. Once those files were out of the way, the client launched and showed a warning banner about imminent incompatibility. This kind of “trick the client” approach is fragile—client updates or missing dependencies can break it at any time.
2. Getting the game onto the legacy machine
- Modern Steam downloads and content servers often assume a modern client and may use transfer/progress checks that fail on an unsupported OS. In this instance the download stalled at a consistent point (the user‑reported 657.5 MB), forcing a pragmatic workaround: download the full game on a modern PC and copy the entire game directory across the network or via an external drive. Once the files were present, Steam could often be persuaded to verify the installation (or a local launcher could be used) and the game executable could be launched. That manual copy‑over approach is crude but effective when the official delivery path is blocked.
3. Filling in missing OS capabilities
- Older Windows versions lack many of the runtime libraries and kernel hooks modern games and engines assume. The fix required community toolchains:
- Community kernel extenders and backports that provide missing APIs or stub out newer kernel behaviors.
- Microsoft Knowledge Base (KB) redistributables—older OSes can accept a number of platform hotfixes and runtime packages that add functionality or repair ecosystem gaps. Carefully chosen KB patches can restore parts of the platform the game expects.
- Visual C++ Redistributables and DirectX runtimes compatible with the Unity engine build.
- This is the riskiest step: applying system‑level patches or kernel extenders changes OS behavior and, if taken from untrusted sources, can introduce instability or security holes.
4. Launch, error handling, and play
- Even after all these changes, expect at least one error or crash on first run. In the example reported by press, a final error occurred but the game still functioned and ran well enough on integrated graphics for a 2D metroidvania to be enjoyable. The lesson: a lot of compatibility work is possible, but it requires perseverance and acceptance of intermittent failures.
What worked well — strengths of the approach
- Small technical surface area of Silksong. Silksong’s Unity 2D foundation and modest system requirements make it uniquely amenable to legacy runs. A heavyweight 3D AAA requires drivers, shader pipelines, and kernel support that older OSes and drivers simply can’t provide.
- Community tooling and documentation. Enthusiast guides, forum threads, and step‑by‑step videos lower the barrier for others to attempt similar installs. Where communities gather knowledge, experiments become reproducible.
- File copy as a robust fallback. When official download paths fail, moving installed files from a modern PC to the legacy machine often bypasses network‑orchestrated checks. It’s primitive, but practically useful.
- Demonstration value. Beyond the practical success, this is a cultural artifact: it shows the resilience of PC ecosystems and the value of user agency when vendors dictate upgrade paths.
What didn’t work, and the real risks
- Security exposure. Running an out‑of‑support OS is inherently risky. No matter how cleverly you get a modern game to run, the OS will not receive security updates, and community kernel patches rarely match vendor‑grade security mitigation. This makes the machine a poor choice for online banking, email, or any sensitive work.
- Fragility. The solution depends on specific client versions, file sets, and community tools. A Steam client update, a missing KB redistributable, or a slightly different game build can break the entire chain. What works today can stop working the next time the Steam client checks its environment.
- Driver and hardware limitations. Modern GPU features, shader models, input stacks, and controller integrations often expect up‑to‑date drivers that aren’t available on Windows 7. You may get a playable frame rate in a 2D game, but 3D acceleration and modern compositor features are unlikely to be reliable.
- Legal and warranty concerns. Copying licensed game files across machines or altering vendor clients may violate terms of service or EULAs. While most users will not be pursued for a hobbyist workaround, organizations or IT departments should treat such tinkering as unsupported.
- Maintenance burden. Applying KBs, kernel extenders, and hacks requires ongoing maintenance. When the machine breaks, troubleshooting is complex; official support channels will not help.
A practical checklist for anyone tempted to try this
- Isolate the machine. If you intend to run an unsupported OS, keep it offline or behind a strict firewall. Don’t use it for sensitive tasks.
- Backup everything. Image the disk before you begin. When you start replacing DLLs or applying community patches, a clean image is your life preserver.
- Gather modern hardware as a staging ground. Use an up‑to‑date PC to download installers or game files and transfer them to the legacy machine.
- Collect dependencies first. Visual C++ redistributables, DirectX runtimes, and any required KB packages should be collected and verified before touching the legacy system.
- Document every change. Keep a step log of renamed DLLs, replaced files, and registry changes so you can roll back.
- Prefer VMs for experimentation. Use a virtual machine to validate steps before applying them to bare metal.
- Be ready to stop. If you cannot get the system stable after a measured attempt, cut your losses. The hobbyist win is fun; long‑term insecure computing is not worth it.
Broader implications: vendor policy, sustainability, and community responsibility
The episode exemplifies a classic tension: vendors push users onward for legitimate technical reasons, while users push back when upgrades are expensive or unnecessary for their needs. There are three converging policy conversations raised by these projects:- Sustainability and e‑waste. Forcing upgrades can accelerate hardware replacement cycles, with environmental costs. Community projects that extend device life can be environmentally positive—but they must not hide security trade‑offs.
- Transparency in compatibility policies. When vendors set hard cutoff dates or dependency requirements (for example, the Steam client’s embedded Chromium dependency) they should document the practical fallout and offer clear, low‑cost migration paths.
- Shared responsibility. Community projects that enable legacy computing owe users clear guidance about risks. Enthusiasts should surface both the fun results and the caveats so less technical users do not inadvertently put themselves at risk.
Verification and caveats
- Valve formally ended Steam support for Windows 7, 8 and 8.1 effective January 1, 2024. That company statement and contemporary reporting are publicly available.
- Team Cherry’s Silksong has relatively modest minimum requirements listed on Steam that historically include Windows 7 as an option; this makes the game a plausible candidate for running on legacy OSes when the engine and drivers cooperate.
- Reporting on the specific step‑by‑step technique—deleting Steam DLLs to force launch, the exact stalled download size at 657.5 MB, and the particular kernel extenders used—originates in press coverage of a YouTube demonstration and community writeups. While multiple outlets repeated the high‑level workflow, some line‑item details (specific file names deleted, the precise point at which Steam stalls) came from a single demonstrator’s video. That video was referenced in reporting but was not always available for independent verification at the time of writing; treat single‑source procedural claims as experimental and fragile. (Readers should be cautious about re‑implementing any steps that modify system files without detailed community‑verified instructions.)
Takeaways for Windows users, gamers, and IT custodians
- For most people: upgrading to a supported OS is the safest path. Vendors stop updating older platforms for sound technical reasons; security patches matter. If your machine is doing essential work, move to a supported platform or enroll in official extended support programs.
- For gamers on budget hardware: when a title’s system needs are low, legacy runs can work—but they’re a hobbyist project, not an IT recommendation. Expect to tinker and to accept the possibility that the setup will break without notice.
- For sysadmins and IT managers: community projects that extend platform life are useful for triage, but they do not replace vendor support and are not a viable enterprise strategy without robust compensating controls.
- For the modding community: successes like this are both inspiring and instructive. Document steps, highlight risks, and maintain reproducible guides so others can learn without courting needless risk.
Conclusion
The story of Silksong running on Windows 7 is equal parts engineering stunt and cultural statement. It’s a reminder that computing is not just a shop of sealed appliances but a malleable platform where resourceful users can reassemble the parts to get surprising results. That spirit—curiosity, patience, and willingness to experiment—fuels much of the PC landscape’s longevity.But the headline spectacle should not mask the practical truth: these setups are complex, brittle, and insecure by default. The community’s ingenuity keeps old systems alive and teaches valuable lessons about modularity and software design. What it cannot substitute for, however, is the ongoing security maintenance an OS vendor provides. In short: applaud the feat, admire the craft, but if your files or finances depend on the machine, choose a supported path.
