Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

How to undo "always open with" option in Windows 10 (1803 build)

I accidentally click "always open with" a particular application on a BibTeX file and now the icons of all such files change to the icon of that app and I cannot find a way to undo the operation. In fact, I want Windows to always ask me how to open
a BibTeX file instead of sticking to a specific program. Thanks for any suggestions!

Here I found some related posts but none of them seem to solve my problem:

• How do I undo "Always open with" option in Windows 10
• How to undo "Always open with" option in Windows 10

Here are what I've tried, but none of them works:

• Execute "assoc .bib= && assoc .bibtex=" in cmd.exe as Administrator.
  Nothing happens.
• In Settings under "choose default apps by file type", remove the default app at ".bib" entry.
  However, there's no such entry.
