Word documents open all at once with OpenOffice?

Since my laptop has updated, all Word documents have been opened with OpenOffice instead of Word as before (only exception with Word documents with macros). If I want to create a new document, the "New Word document" option is no longer available. Why is that suddenly and how can I undo it?

Under the file properties you can choose which program should open this type of file by default…

Unfortunately, I can't say why you no longer have the "New Word document…" entry in the context menu…

Have you ever checked if Office is still installed?

I have already looked under the properties, but there's also no option "open with Word"…

If you open a file go to "open with" then stop word and then choose "always open with this application" done

Then you should really check whether MS Office is still on your computer at all…

For some reason, that's no longer possible…

Right click on Word file / open with / and below Extended / open with Word (don't forget the check mark for "always open with this program" / ok - done
