Windows 10: Double click doesn't open htm/html files

Hi, I've no idea why you might have the extra string as part of the key name, I'm afraid. Yes, I use FF 32 bits rather than 64.

However, you've said that the problem applies whichever browser you attempt to select, so my guess is we're not looking at the right thing, but I don't know where else to look - sorry.

You could create a new user for test purposes and see if the behaviour is different then. Also check in Safe Mode if you've not already done that.

Remember you said the icon was missing?
See what you have here:

 

Yes, already tried in Safe mode. I'm going to test unistalling 64 bit version and using 32, so I could let you know. Maybe this 64 bit installation messed the file association for all browsers in some way...

 

*Banghead*Banghead*Banghead
no way.....32 or 64 bit versions don't change, also unistalling all Firefox version and rebooting in Safe Mode, still double click on htm/html file doesn't work....

Thank for your support...hope someone else could give me a tip or Windows will give a fix, since it seems that is quite early common problem on Windows 10 Pro 64 bit versions...

 

You could create a new user for test purposes and see if the behaviour is different then - as I said above.

If it is, you know the problem is related to the user configuration; if not - it's deeper.

In that case you could try an in-place upgrade repair install - which is relatively painless.

 

Really?
Look that I'm not full Administrator, but Administrator of the device (we are connected to a company domain), and I don't know if I could mess a lot to try fixing this....

 

Those are normal repair/diagnostic actions and should not be a surprise. However I can appreciate in some situations these are not activities a user can or should undertake.

If you are in a company situation, I suggest you talk to your IT dept. I'll have to leave that with you. Good luck.

 

Yes, my IT dept talked that is just a tiny bug that I can workaround with Open command...

Thank for your support!

 

Update, SOLVED: since there was another silly problem (Acrobar Reader still changed it's icon), our Windows Server Domain manager decide to rebuid the user profile, and now the problem has been fixed without any other action.
Thaks for support!
Hope this can help other users.
