Restore Default File Type Associations in Windows 10  

Brink said:

When you use "Open with" on the files to select the .exe of the program, are you checking the "Always use this app to open" box?

Absolutely! But still, my settings won't saved.

Odd. I'll have a play with it later today when I get home to my desktop with Office 2016 installed to see how it behaves on it.

Many thanks Brink! I'll be waiting :)

Ok @bima1997, :)

If you like, you could download and merge the .reg file below to see if it may help since you have the 32-bit Office 2016 installed like me. It will restore the default associations and registry entries for .doc, .pps, and .xls.

doc_ppt_xls.reg

Umm, actually I got the 64-bit Office 2016 installed Brink, lol 😂
But well, let's try it.

Thanks in advance.

If it doesn't help, then reinstalling Office 2016 to act as a repair install may.

Okay, I will try your advices.

Many thanks Brink!

Hello Brink,

I've managed to set old Office files (.doc, .pps, .ppt, .xls, etc) to be opened in Office 2016!
So, I use Office Cleaner from Microsoft to remove all of my Office installation, restart my computer, and then reinstall it again. After the installation is finished, I set my old Office files to be opened in Office 2016 via "Open With" and it works like a charm

Thanks for your assistance, Brink! :)
