If Notes crashed immediately after startup, here is how you can fix it.
Always try shutting down your PC and do a cold boot first to see if that fixes your problem.
If that doesn’t work, search for msconfig.exe and execute. Ensure “Normal startup” is checked, click OK, and reboot your computer.
If that doesn’t solve your problem, do the following:
First, backup the sticky notes file (plum.sqlite) to a safe place. The file is located here:
If you want to read what is inside plum.sqlite in order to copy the data out, you can download the free sqlite browser tool here:
Reset Sticky Notes by going to Apps and Features in settings. After locating Sticky Notes, click Advanced Options and click Reset.
Go to the Microsoft Store, search for Microsoft Sticky Notes, and install.
Go back to the location where the sticky notes you backed up resides and replaces the plum.sqlite file with the one you backed up.
For those of you (like me) where sticky notes would not uninstall by clicking reset on the app or uninstalling using Powershell by entering:
Get-AppxPackage Microsoft.MicrosoftStickyNotes | Remove-AppxPackage
you can try removing it manually like this:
Give yourself permission to delete these folders and delete them.
The file location is:
The packages begin with Microsoft.MicrosoftStickyNotes
Now go to the Microsoft Store, install Microsoft Notes, and restore your backup of file: plum.sqlite.
Hope this helps!
