If Microsoft To Do opens and closes right away, treat it as an app or Microsoft Store issue before assuming your task list is lost. Confirm your tasks on the web, then repair, reset, or reinstall the app and refresh Store updates.
What Happens When Microsoft To Do Opens and Closes Immediately
Microsoft To Do is failing to stay open, which blocks normal task management in Microsoft 365. When the window opens and closes immediately, the problem is more often damaged app data, Microsoft Store cache, or Windows app registration than a missing task list.
Quick Answer for a Microsoft To Do App That Keeps Closing
First check whether your tasks still appear in Microsoft To Do on the web. If they do, your data is synced and it is safer to repair the desktop or Store app. Go to Settings > Apps > Installed apps > Microsoft To Do > Advanced options, choose Repair, then Reset if needed. Also reset the Microsoft Store cache with wsreset.exe, install Store updates, and restart the PC. If To Do still crashes, uninstall it, restart, and reinstall from Microsoft Store.
Possible Causes When Microsoft To Do Crashes on Launch
Microsoft To Do app data may be damaged.
Microsoft Store cache or app registration may be out of date or broken.
Missing Store updates can block the app from launching cleanly.
Incorrect Windows date, time, region, or Windows Update status can interfere with Store apps.
If Microsoft Store itself opens and closes, Windows Store app registration may be the root issue.
Recommended Solution: Verify To Do on the Web, Then Repair, Reset, or Reinstall
When to use this: Use this when Microsoft To Do opens and closes immediately and you need to restore a working app without risking your synced tasks.
Office-related app failures are commonly caused by damaged local app data, outdated Store builds, or a broken Store registration. Start with a low-risk data check, then progress to repair and reinstall.
Open Microsoft To Do on the web and confirm whether your tasks are still visible. If they are there, your data is synced and it is safer to repair or reinstall the app.
Go to Settings > Apps > Installed apps > Microsoft To Do > Advanced options, then choose Repair. If that does not help, choose Reset to refresh local app data without reinstalling Windows.
Reset the Microsoft Store cache: press Windows + R, type wsreset.exe, then press Enter. After it finishes, open Microsoft Store > Library > Get updates, install all updates, then restart the PC.
If To Do still crashes, uninstall Microsoft To Do, restart the computer, then reinstall it from Microsoft Store.
Confirm that Windows date, time, region, and Windows Update are correct, because Store apps can fail to launch when those settings are out of sync.
If Microsoft Store also opens and closes, the issue may be with Windows Store app registration rather than To Do itself. In that case, repairing Windows apps or re-registering Store apps through PowerShell may be needed.
Why this works: Checking the web first protects synced tasks. Repair and Reset clear damaged local app data, while Store cache reset and reinstall address Store-side launch failures.
If this fails: Note whether Store itself launches, record any error text if shown, and escalate Windows Store app registration repair or Microsoft support for Store apps.
Keep Managing Documents With WPS Office While Microsoft To Do Is Unavailable

WPS Office cannot repair Microsoft To Do, Microsoft Store cache, Windows app registration, or Microsoft account sync for To Do. Those steps stay with Microsoft and Windows.
While To Do is unavailable, WPS Office can still help with everyday document work:
Download and install WPS Office on your computer.
Open WPS Writer, Spreadsheets, or Presentation for local documents, lists, and notes you keep as files.
Save copies locally so checklist or project notes stored as documents remain editable.
Return to Microsoft To Do after the app launches successfully again.
This keeps general office work moving while the To Do app is being repaired. If you need a practical Office-compatible suite during the outage, try WPS Office.
