First identify the exact editor and failure: does it refuse to launch, crash, fail to play a video, or stop during export? Windows 10 does not have one universal video-editing app, and the right fix depends on the app and symptom. For an installed app that offers Windows repair controls, try Repair before Reset; Reset can erase app data.
Identify the editor and the problem
Find the app’s exact name in Start or under Settings > Apps > Apps & features. Note your Windows version and build, any error text or code, and the point at which the failure occurs. “Video editor” is not a specific Windows 10 app: Microsoft’s page describing Clipchamp as the built-in editor is for Windows 11, so it does not establish that Clipchamp is the editor on your PC. Microsoft’s Windows photo and video apps page makes that distinction.
Separate an app launch or crash problem from a project-specific issue, trouble with a source file or playback, and a failure that happens only during export. If possible, check whether another app can open the same video. These symptoms do not all point to the same cause, so record what works and what fails before changing app data.

Try low-impact checks first
Restart and check the editor’s official update route
Restart Windows, then check for an update using the editor’s own update feature or its official distribution channel. The exact update steps vary by editor; follow that publisher’s support instructions rather than using an unofficial download site.

Check whether the failure is limited to one file or project
If the editor opens but one project or video fails, test a different project or source file when you can do so safely. A failure limited to one item is useful diagnostic evidence; it does not by itself prove that Windows or the whole app installation is damaged.
Run Repair in Windows 10
Windows offers Repair for some apps. Microsoft’s Windows 10 path is:
Rank #2
- 5-in-1 Connectivity: Equipped with a 4K HDMI port, a 5 Gbps USB-C data port, two 5 Gbps USB-A ports, and a USB C 100W PD-IN port. Note: The USB C 100W PD-IN port supports only charging and does not support data transfer devices such as headphones or speakers.

- Open Start > Settings > Apps > Apps & features.
- Select the video editor, then choose Advanced options if that option appears.
- Select Repair and let Windows complete the operation.
- Open the editor again and check whether the original symptom is resolved.
Some desktop programs and apps do not expose Advanced options or Repair. If the control is missing, that is not proof that the app is broken; use the editor publisher’s instructions for that installation instead. Microsoft’s Windows app repair guide describes the Windows 10 route and notes that available options depend on the app.

Understand the effect before choosing Reset
Use Reset only if Repair is unavailable or did not solve the problem, and only after considering the app’s data. Microsoft documents that Repair retains app data, while Reset deletes app data and returns the app to a fresh state. Preferences and sign-in details may therefore need to be restored. The distinction is documented for MSIX/Windows apps, not every traditional desktop program; see Microsoft’s Reset or Repair MSIX apps guidance.

Before resetting, make sure project files and original video, audio, and image assets are safely stored. Check whether the editor keeps project data locally or in an account, and confirm that you can access anything you may need after a reset. The exact location and recovery behavior depend on the editor, so do not assume that a project is protected just because its source footage is saved elsewhere.
Reinstall only through the editor’s official route
If Repair and, where appropriate, Reset do not help, reinstalling may be reasonable when the app package itself appears damaged. For Store apps, Microsoft’s technical guidance identifies Microsoft Store or winget as ways to obtain a fresh package in applicable cases; availability depends on the app. Start with the editor publisher’s instructions or the app’s official Store listing. Avoid third-party download mirrors.

Package registration, permissions, deployment policy, or activation errors may require a more specific fix than an ordinary reinstall. Microsoft’s Store and inbox app troubleshooting guidance covers these technical cases and relevant event logs, but is written for support agents and IT professionals. If the error points to package deployment or policy, ask the app publisher or a qualified administrator rather than running broad removal or copied registration commands without confirming the app and user context.
Use Windows system repair only when the evidence supports it
System-file checks are escalation steps, not routine fixes for a single editor, project, or video file. Consider them when other symptoms suggest broader Windows component or system-file corruption. Microsoft documents sfc /scannow as a check and DISM Cleanup-Image commands for checking or repairing the Windows image. These tools require the correct command, an elevated administrator context, and careful interpretation; consult Microsoft’s Windows image repair guidance for the applicable instructions. That page’s version context is Windows 11, so verify current Windows 10 guidance before applying its commands. Neither tool guarantees a fix for an isolated editor fault.

Choose the next step by scope and risk
| Action | Scope | App-data impact | Availability or skill needed |
|---|---|---|---|
| Repair | One app | Microsoft says app data is retained for the documented packaged-app repair behavior | Only available for some apps; use Advanced options when present |
| Reset | One app | Deletes app data for the documented packaged-app reset behavior | Only available for some apps; safeguard projects and assets first |
| Reinstall or package troubleshooting | One app or its package | Depends on the app and method; check its publisher’s guidance | Availability varies; deployment or registration issues may need an administrator |
| DISM or SFC | Windows image or system files | Not an app-data repair | Advanced escalation; use current Windows-specific instructions and administrator context |
Account for Windows 10 support status
Microsoft states that standard Windows 10 support ended on October 14, 2025. Its support notice says that after that date, Microsoft no longer provides free Windows Update software updates, technical assistance, or security fixes for Windows 10; the PC continues to work. Check Microsoft’s support notice for current details, including any applicable extended-support terms.
If the editor still fails
When contacting the editor publisher or a qualified support person, provide the app’s exact name, Windows version and build, the symptom, the full error text or code, whether other apps open the same media, and which steps you tried. That information helps distinguish an app launch fault from a project, media, package, or wider Windows issue without repeating risky changes.
