bad_module_info is usually a Windows Error Reporting label attached to an application crash, not a program, DLL, virus name, or diagnosis. It can appear when a game freezes or closes, but the same label is also used for unrelated applications. Because the label does not identify one damaged file, the reliable fix is to inspect the surrounding crash record, then work through updates, driver and startup-conflict tests, device checks, Windows component repair, and finally an application repair or reinstall.

Do not download a file called bad_module_info.dll or delete system files because this text appeared. The useful clues are the affected game’s path, exception code, faulting module, timing, and whether other programs fail too.

What is bad_module_info?

bad_module_info is a generic Windows crash-reporting label. In Windows Error Reporting (WER), it can be shown as the application name for an APPCRASH event even when the actual game or program is listed elsewhere in the record. A Microsoft Q&A example shows Application Name: bad_module_info, version 0.0.0.0, Fault Module Name: StackHash_0000, and a fault-module version of 0.0.0.0. Another report uses StackHash_2beb and an unknown fault module. Those fields describe a crash-report bucket; they do not name a file you can safely replace.

The label has been reported with games and with other applications. A 2026 explanation from GeekChamp Team puts the distinction plainly: “Bad_Module_Info is a Windows crash label, not a diagnosis.” The same message can therefore result from different games, drivers, Windows components, or stability problems. Treat it as the starting point for investigation rather than as the cause.

What does StackHash_0000 mean?

A StackHash_ value is a generic signature Windows uses when it cannot provide a normal, useful faulting-module name. StackHash_0000 does not mean that a file with that name is installed, missing, or corrupt. It also does not prove that the application itself is at fault; the crash may involve a graphics driver, another device driver, Windows, or software that hooks into the game.

Why are the version and path often meaningless?

Placeholder values such as 0.0.0.0, an unknown module, or a non-file path occur in the generic reports associated with this label. They are metadata limitations, not instructions to search the internet for a matching executable. The actual application path, event time, exception code, and any named DLL or driver elsewhere in the record are more useful.

Field in a crash record What it can tell you What it cannot establish alone
Application name: bad_module_info Windows classified the event under a generic crash label. Which game component caused the failure.
Version: 0.0.0.0 The report has placeholder or unavailable version metadata. That the game is necessarily missing or malicious.
StackHash_0000 or another StackHash value Windows recorded a generic crash signature. A repairable DLL named StackHash or bad_module_info.
Unknown or non-file fault path WER could not resolve a conventional module path. That no underlying module, driver, or hardware issue exists.

Is bad_module_info a virus or malware?

The label itself is not presented in the available Microsoft reports or current troubleshooting guidance as malware. Its generic version and path fields are consistent with a reporting placeholder, not with a downloaded program. That does not certify every file on the computer as safe: the affected game’s publisher, the download source, and any unexpected executable still need to be verified.

Use the program’s official publisher or store as the source for updates. If an unexpected download appeared at the same time as the crashes, scan it with Windows Security and check its file location and digital-signature information. Do not download a supposed “bad_module_info” replacement, and do not delete Windows files merely because a report contains that text.

  • Investigate the process path and the named faulting module, if WER provides one, rather than the label alone.
  • Keep security protection enabled. Do not permanently disable it to test a game.
  • If a vendor specifically asks for a temporary security change, make the test brief and restore protection immediately afterward.

Why do games crash with bad_module_info?

There is no single cause. Microsoft notes that an unexpected failure can involve a hardware device, its driver, or software. The practical distinction is whether one game fails in a repeatable way or several unrelated programs fail across normal use.

Pattern Clues to record Most useful first direction
One game or launcher only The same executable, level, or action triggers the close; other programs remain stable. Update or repair that game, verify its files, and review overlays or launcher components.
Several games using the same graphics workload Crashes began after a display-driver change, or a black screen and recovery appear. Check the display driver, test a rollback or clean reinstall, and inspect related hardware events.
Many unrelated applications Different programs fail, especially after a Windows, driver, or startup-software change. Use Safe Mode or a clean boot, inspect Device Manager, and repair Windows components.
Crash plus black screen, restart, or blue screen The failure is not limited to an application window. Preserve WER and dump information and prioritize driver, hardware, and Windows recovery checks.
Only one recent session No repeatable trigger and no other system symptoms. Record the event, update normally, and avoid destructive changes until the pattern is clear.

Timing is a valuable clue. A failure that begins immediately after a graphics-driver, Windows, game, launcher, or overlay change should be tested against that change. A named module such as a display driver is more actionable than StackHash_0000, but it still needs to be considered alongside the failure mode and reproducibility.

How should I collect evidence before changing anything?

Record the event while it is fresh. A precise record prevents you from replacing unrelated files and gives a game developer, hardware vendor, or technician something they can analyze.

  1. Write down the scope. Note the game or application, the Windows edition, whether one title or several programs fail, and whether the symptom is a close, freeze, black screen, restart, or blue screen.
  2. Open Reliability Monitor. Search Windows for View reliability history, open the result, select the red failure at the matching time, and open the technical details. Copy the application name, faulting module, exception code, and report time.
  3. Check Event Viewer. Open Event Viewer, go to Windows Logs and Application, and locate the error at the same time. The event may contain a process path or module name that the brief popup did not show.
  4. Save WER locations. Microsoft Q&A examples place archived reports under C:ProgramDataMicrosoftWindowsWERReportArchive. Preserve the relevant folder and note any minidump path shown in the event. Do not edit the files while you are still collecting evidence.
  5. Record recent changes. List the date of the last Windows update, game or launcher update, display-driver change, overlay installation, peripheral connection, or hardware change.
  6. Try to reproduce safely. Write the exact action that triggers the failure, how long the game runs, and whether the same action fails after a restart. A repeatable case is more useful than a one-off label.

How do I fix bad_module_info errors on Windows?

Work from the least disruptive checks to the more involved repairs. Stop when the crashes are resolved, but keep the evidence if the problem returns.

1. Update Windows, the game, and its launcher

Install pending Windows updates through Settings > Windows Update. Update the affected game and launcher from their normal publisher or store channel. Restart after updates that request it, then test the same workload again. If only one title is affected, use its built-in update or verify-files feature before changing system files.

2. Update, roll back, or clean-reinstall the relevant driver

Display drivers are a common place to look when games fail, but audio, network, storage, chipset, USB, and other device drivers can also matter. In Device Manager, expand the relevant category, open the device’s Properties, and review the Driver tab. If the issue began immediately after a driver update, test the available rollback option or install the previous stable package from the hardware vendor. If an update is damaged or incomplete, remove and reinstall the vendor’s official package rather than downloading a file named after the crash label.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Use a clean reinstall only when a normal update or rollback does not address the timing. Record the current driver version first so you can return to a known state. A driver change should be judged by whether the game and other graphics workloads become stable, not by whether the generic label disappears from an old report.

3. Test Safe Mode and then a clean boot

Safe Mode starts Windows with a limited set of drivers and services. If the crash disappears there, a normal-startup driver or service becomes more likely; if it still occurs, a basic Windows or hardware issue remains possible. Safe Mode is a diagnostic test, not a permanent gaming configuration.

A clean boot starts Windows with a minimal set of drivers and startup programs. Use it to isolate overlay, injector, monitoring, RGB, capture, launcher, and other background conflicts. Disable nonessential startup items and services temporarily, restart, and run the affected game. If stability returns, re-enable items in small groups until the conflicting component is identified. Restore normal startup settings after testing so you do not leave unrelated software disabled.

4. Check Device Manager and available disk space

Open Device Manager and look for warning icons. For a device with a warning, review its status, update its driver, or temporarily disable or uninstall it only when you understand what function it provides. Reboot and test after each meaningful change instead of changing several devices at once.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Check free space on the Windows system drive and the drive that holds the game. Windows and applications need working space for updates, caches, paging, and temporary files; a nearly full drive can prevent normal operation. Free space is a prerequisite check, not proof that removing arbitrary files will solve the crash. Keep personal saves and installation files backed up before deleting anything.

5. Repair Windows components with DISM and SFC

When several applications fail or Windows files may be damaged, use Microsoft’s documented repair order. Open Windows Terminal (Admin) or Command Prompt (Admin), approve the elevation prompt, and run:

DISM.exe /Online /Cleanup-image /Restorehealth

Wait for DISM to finish. Then run:

sfc /scannow

Allow System File Checker to reach 100 percent. Restart Windows after the commands complete and test the original workload. If either tool reports that it could not complete, keep the exact message; repeated failures across applications warrant recovery or professional assistance rather than repeated blind commands.

6. Repair or reinstall the affected game or application

When one game is affected and Windows is otherwise stable, use the launcher or Windows app settings to repair or verify the installation. If that does not help, uninstall and reinstall from the publisher or store. Before removing a game, check whether its saves, configuration, mods, and screenshots are stored outside the installation folder and back up anything important. Reinstalling is most useful for a title-specific failure; it is unlikely to cure simultaneous crashes in unrelated programs.

7. Use recovery options when the problem follows a known change

If crashes began after a recent driver, application, or Windows change and ordinary rollback is unavailable, Windows recovery options or System Restore may provide a controlled way back to an earlier state. Choose a restore point that predates the change and read the affected-program list before confirming. Keep current personal files backed up and retain the WER evidence so you can explain what changed if the rollback does not help.

How do I choose the next step from the crash pattern?

Use scope, timing, faulting-module information, failure mode, and reproducibility together. No single field is decisive, especially when the report contains a StackHash value.

Observation Interpretation Next test
Only one title closes; Windows remains responsive. A title-specific installation, update, launcher, mod, or overlay is more plausible. Update, verify, repair, or reinstall that title and test without nonessential overlays.
Several titles fail after a graphics-driver update. The common driver or its interaction with the graphics stack deserves priority. Rollback or clean-reinstall the official display driver and compare results.
Different applications fail after startup software was installed. A background conflict may be injecting into multiple processes. Use a clean boot, then restore items one at a time.
Crashes accompany black screens or automatic restarts. The event extends beyond a normal application exception. Preserve dumps and WER records and investigate drivers, hardware, and Windows recovery.
The report names a specific DLL or driver. The named component supplies a concrete lead, although it is not automatically guilty. Check its publisher, version, recent changes, and vendor-supported rollback or update.
The report contains only StackHash and unknown fields. Windows did not resolve a useful module in that event. Rely more heavily on scope, timing, reproducibility, and related events.

What should I not do?

  • Do not search for a “bad_module_info.dll.” The reports do not identify such a repairable file.
  • Do not delete system files or edit the registry based on the label alone. A generic crash bucket cannot justify a destructive change.
  • Do not assume a RAM upgrade, GPU replacement, or full Windows reinstall is required. Those decisions need evidence from repeated failures, hardware diagnostics, or vendor guidance.
  • Do not permanently disable security software. A temporary vendor-directed test is different from leaving protection off.
  • Do not change many variables at once. If you update Windows, replace a driver, remove overlays, and reinstall the game simultaneously, you lose the ability to identify what helped.
  • Do not discard the first report. Old WER entries and dump paths can reveal whether the issue is new, recurring, or shared by several applications.

When should I escalate the problem?

Escalate when crashes continue across unrelated applications after updates, clean-environment testing, device checks, and Windows component repair. Escalation is especially important when failures include black screens, automatic restarts, blue screens, or signs that a device is disconnecting. Microsoft guidance identifies hardware, drivers, and software as possible causes, so a qualified technician or the relevant hardware vendor may need to examine the system.

Provide the affected application’s name and version, Windows edition and build, exact reproduction steps, event time, exception code, faulting module, recent changes, and the WER report or minidump paths. If a graphics-related event names a driver such as nvlddmkm.sys, include that detail rather than replacing files manually. A game developer can use the same package to distinguish an application defect from a system-wide stability problem.

As an optional shortcut after the manual checks, Outbyte PC Repair can look for common Windows issues, clean temporary and cache files, review certain settings and vulnerabilities, and provide crash-log information. It is a complement to antivirus software, not a replacement; results vary, no tool repairs every crash, and its free trial lasts by category for at least two days before a paid subscription.

Frequently asked questions

Why does the report show version 0.0.0.0?

That value is used in the generic reports associated with this label when Windows does not have a normal application or module version to display. It is a limitation of the event metadata, not evidence that the installed game has literally been assigned version zero.

Can deleting WER reports fix the crash?

No. Removing an archived report only removes diagnostic history; it does not change the driver, game files, or Windows components that produced the failure. Copy the relevant report first if you may need support, then clean old reports only for storage or privacy reasons.

Should I send the report to the game developer?

Yes, when the failure is title-specific or remains reproducible after system checks. Include the game’s exact build, launcher, Windows build, reproduction steps, exception code, faulting-module text, and the matching WER or dump path instead of sending only a screenshot of bad_module_info.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Does one bad_module_info event prove that hardware is failing?

No. One generic event cannot separate an application fault from a driver, Windows, or hardware problem. Repeated failures across unrelated workloads, device warning icons, black screens, restarts, or blue screens provide a stronger reason to prioritize hardware and driver diagnostics.
