What Is Microsoft To Do?
Microsoft To Do is Microsoft's task and reminder app for personal lists, planned tasks and simple shared lists. On Windows it can sync with your Microsoft account so your tasks and reminders stay consistent across devices.
It is not a core part of Windows. If you use it, starting it with Windows can make reminders and syncing available sooner after sign-in. If you do not use it often, there is usually no reason to let it run at startup.
Is It Safe?
Usually, yes. Microsoft To Do from Microsoft Corporation is a legitimate app.
If you want to verify it, check the file location and signature. A genuine Store-installed app may not behave like a classic desktop program, so the exact path can vary. In Task Manager, right-click the process and use Open file location if available, then check Properties > Digital Signatures for Microsoft. If the file is in an unusual folder, lacks a Microsoft signature, or you did not install it, treat that as suspicious and investigate further.
Microsoft To Do is not required for Windows itself. Ending it should not harm the system, though it can close reminders or pause syncing until you open it again.
Should I Disable It at Startup?
For most people, yes if you want fewer apps loading when you sign in. Microsoft To Do should still open normally when you launch it yourself.
Keep it enabled at startup only if you rely on its reminders immediately after login or want it ready in the background all the time. Otherwise, disabling startup is a reasonable cleanup step with low risk.
Why Is It Using High CPU or Memory?
Short spikes can happen when the app starts, signs in, syncs tasks, downloads changes or shows notifications. That is usually temporary.
If usage stays high, common causes include a stuck sync, a corrupted app state, or a sign-in problem. Close and reopen the app first. If that does not help, sign out and back in, or reset the app from Windows app settings if that option is available on your system. If the process name, file location or signature looks wrong, investigate it instead of assuming it is the real app.
How to Disable or Remove It
If Microsoft To Do appears in Settings > Apps > Startup or Task Manager's Startup apps, you can disable it there. Not every installation exposes a normal startup entry, so you may not see one.
To remove it completely, uninstall Microsoft To Do from Settings > Apps if you do not use it. If it was installed from the Microsoft Store, you can also remove it from the Start menu or Store library. Uninstalling the app removes the program, but your synced tasks should remain in your Microsoft account.
Where Kudu Helps
Kudu can show whether Microsoft To Do has a startup entry and lets you disable or remove supported startup items without digging through Windows locations manually. On Windows, Startup Manager also shows boot time impact when available.
If To Do seems busy in the background, Kudu's Performance Monitor can show its CPU and memory use and help you confirm whether it is a brief sync spike or a process that stays active too long. If something claiming to be To Do looks suspicious, Kudu's Malware Scanner can check for persistence and suspicious files, but it should complement your antivirus rather than replace it.
Frequently asked questions
- Is Microsoft To Do required for Windows?
- No. It is a user app, not a core Windows component.
- Will disabling Microsoft To Do at startup delete my tasks?
- No. Disabling startup only stops it from launching automatically when you sign in. Your tasks should remain in the app and in your Microsoft account if sync is enabled.
- Why can't I find a startup entry for Microsoft To Do?
- Some app installations do not create a normal startup item that Windows shows in the usual places. It may simply launch on demand instead of registering as a standard startup app.
