How to Stop Photos and Calculator Apps on Windows 10: A Comprehensive, Practical Guide
When the Photos and Calculator apps open unexpectedly, run in the background, or steal file associations, it can feel like Windows 10 is doing its own thing. These are modern UWP apps that integrate with the Microsoft Store and system services. Because they are part of the default Windows image, they can relaunch after updates or start in the background to sync thumbnails and telemetry. This guide provides a full, methodical plan to stop Photos and Calculator from launching when you don’t want them to, reduce background activity, and maintain long-term control. It also explains how Windows handles default apps, scheduled tasks, and app permissions so you can make changes confidently without harming system stability.
Why Photos and Calculator Keep Appearing
Windows 10 uses “app defaults” and system associations to decide which app opens a file or handles an action. Photos is a default viewer for images, while Calculator is a default system utility. Even if you close an app, Windows may reopen it due to file association triggers, Store update cycles, or background tasks that prepare fast startup. The task isn’t just to close the app once; it’s to configure the system so the app isn’t called in the first place. That means shifting defaults, disabling background privileges, and managing auto-updates that can reset those choices.
Step 1: Change Default Apps to Break the Trigger Loop
The most reliable way to stop Photos from opening is to change image defaults to another viewer like Windows Photo Viewer or a third-party app. Open Settings > Apps > Default apps. Click “Photo viewer” and choose your preferred application. For Calculator, there’s no file association, but it is often triggered by the Run dialog or keyboard shortcuts; you can redirect by using alternate tools or manage system shortcuts through policies or registry tweaks.
- Choose a non-Store photo viewer to reduce Photos triggers.
- If a third-party tool is used, ensure it’s updated and trusted.
- For quick calculations, use web-based calculators or PowerToys Run to avoid the Calculator app.
Step 2: Disable Background App Access
Windows 10 allows UWP apps to run in the background to update content, receive notifications, and sync data. Disabling background access limits Photos from indexing new images and stops the Calculator app from holding resources after use. Go to Settings > Privacy > Background apps, then toggle off Photos and Calculator. In newer builds, this may appear as “Background app permissions” under each app’s Advanced options.
If you’re on Windows 10 Home, you can still disable background apps per-app. On Pro and Enterprise, you can also use group policy to enforce the rule across user profiles.
Step 3: Use Advanced Options to Reset or Repair Apps
Sometimes the Photos app caches corrupted data that causes repeated launches. Resetting clears data without uninstalling. Go to Settings > Apps > Apps & features, click Photos or Calculator, and select Advanced options. Use “Repair” first; if that fails, choose “Reset.” A reset will remove local data, so ensure you have backups of custom settings.
| Action | Effect on Photos/Calculator | Recommended When |
|---|---|---|
| Repair | Fixes app binaries without deleting settings | App opens but crashes or behaves unpredictably |
| Reset | Clears app data and cache | Persistent auto-launch or corruption symptoms |
| Reinstall | Removes and adds app package anew | After failed updates or advanced troubleshooting |
Step 4: Control Auto-Updates to Prevent Reversion
Photos and Calculator are distributed via the Microsoft Store. Updates can re-enable defaults or background permissions. In the Microsoft Store, open Settings and disable automatic updates. You can also manage this via Group Policy on Pro or Enterprise: “Turn off Automatic Download and Install of updates” for the Store.
Keep in mind that disabling updates can affect security and feature patches. A balanced approach is to disable automatic updates but manually check monthly. For security guidance, consult resources such as the Cybersecurity & Infrastructure Security Agency for general update hygiene recommendations, and the National Institute of Standards and Technology for secure configuration baselines.
Step 5: Manage Notifications and Permissions
Notifications can make an app appear as if it’s “popping up.” Disable Photos notifications in Settings > System > Notifications & actions. Similarly, review app permissions under Settings > Privacy for photos and camera access. Limiting access can reduce background scanning. Calculator rarely needs permissions, but removing it from background privileges ensures it doesn’t run when not in use.
Step 6: Verify Startup and Task Scheduler Behavior
Neither Photos nor Calculator is a traditional startup program, but related tasks can trigger scans or cache updates. In Task Scheduler, search for tasks linked to Microsoft Photos or Shell Experience. Be cautious: disabling system tasks can affect broader system features like file indexing or search. If you’re unsure, document the original state first.
Step 7: Group Policy and Registry Options (Pro/Enterprise)
On Pro or Enterprise editions, Group Policy can enforce default app associations and disable background apps for specific UWP packages. Use the “Set a default associations configuration file” policy and export your current defaults, then apply a custom XML to lock in changes. Registry edits can also set default handlers, but these are version-sensitive and should be used only when necessary. For formal IT environments or student devices, consider guidance from reputable institutions like Carnegie Mellon University on system hardening practices.
Step 8: Reinstall or Remove the Apps (Last Resort)
If you want to remove Photos or Calculator completely, you can use PowerShell. This is not recommended for most users because Windows updates may restore the apps, and some dependencies may require the package. That said, if you are managing a kiosk or a controlled environment, removal can be a valid choice. Example PowerShell commands can remove packages per user, but an OS update might re-install them. The long-term solution remains: enforce defaults and background permissions rather than simply removing apps.
| Control Layer | Primary Tools | Impact on App Behavior |
|---|---|---|
| User Settings | Default apps, Background permissions | Stops automatic launch for file types and background activity |
| Store Management | Auto-update settings, Store policies | Prevents update-driven reversion of defaults |
| System Policies | Group Policy, XML default associations | Enforces app behavior across devices and users |
Practical Workflow for Home Users
For most home users, the safest and most effective workflow is: change the default photo viewer, disable background apps for Photos and Calculator, and turn off Store auto-updates if the apps keep reverting. Combine that with notification controls and periodic maintenance. This keeps your system lightweight and predictable without resorting to risky removals. If you notice the apps launching due to file previews or thumbnail rendering, consider turning off preview panes in File Explorer to further reduce triggers.
Practical Workflow for IT and Managed Devices
IT administrators should prioritize policy-driven controls. Export default app associations and deploy via Group Policy, then use AppLocker or Microsoft Defender Application Control to restrict access if needed. Ensure that the Store policy aligns with your compliance requirements. A consistent device image reduces the chance of a user re-enabling Photos or Calculator inadvertently. Document the change so help desk teams know how to troubleshoot when a user wants a specific viewer or calculator tool.
Common Misconceptions and How to Avoid Them
Many users assume that simply closing Photos stops it. In reality, closing the window doesn’t stop system-level triggers. Another misconception is that uninstalling the app permanently removes it. Windows updates can reintroduce it, and system dependencies might call it. The better approach is layered control: defaults, permissions, and policies. Finally, be cautious with registry hacks; they can create instability after updates. Always create a restore point before deeper changes.
Maintaining Long-Term Control
The key to stopping Photos and Calculator in Windows 10 is persistence. After a major update, re-check your default apps and background permissions. Keep a small checklist: verify default photo viewer, check background app toggle, confirm Store auto-update settings, and validate notifications. If you use a third-party viewer, ensure it remains installed and up to date so Windows doesn’t fall back to Photos. For Calculator, consider pinning your preferred tool and removing the Microsoft Calculator from Start to reduce accidental launches.
Summary
Stopping Photos and Calculator apps from launching or running in the background on Windows 10 is not a single-step fix. It’s a coordinated process involving default app settings, background permissions, update control, and occasional maintenance. By applying the steps above, you’ll reclaim system control while maintaining stability.
