Which app do you want to change or set as default ?
Meanwhile, if this problem is NOT too long ago, and if you do remember a date you did not have this problem, please do a system restore.
Pick a date when you did NOT have this problem as your restore point.
System Restore Windows 10
This may not solve all your problems.
In Windows Vista and Windows 7, we have this method to set default programs.........
You can still use it in Windows 10.
Right click at Start button > click Control Panel > top right, click View by: > select small or large > click Default Programs > click set your default programs > wait for loading > left side, click at the program you want to set as default > right side, click Set this program as default > click OK when done.
Suggestion only :
System file check to look for corrupt files. It will try to do repair if any found...................
Right click at Start button > click Command Prompt (Admin) > at the flashing prompt, copy/paste this.......
sfc /scannow
> press Enter.
It will take quite sometime.
When finished, it will give you one of the 3 reports...............(paraphrasing)
1. No integrity violation.
2. Found corrupt files and repair successful.
3. Found corrupt files but unable to repair.
If the report is #1, your solution lies elsewhere.
If the report is #2, check if your problems have been resolved.
If the report is #3, use this method listed below................
In the same Command Prompt (Admin) windows, copy and paste this command...........
dism /online /cleanup-image /restorehealth
> press Enter.
Again it will take some time.
When finished, it will give you a report.
I tried sfc & dism commands... no problems found.
I'll wait for the Windows 10 Anniversary Update and I'll install the ISO.
Would you care to download 10586 ISO and do a Repair Install ?
Tech Bench link for Windows 10, 10586 iso file
https://www.microsoft.com/en-us/soft...brrWLRbagYCa0w
After iso is downloaded, right click at it > click Mount > click Setup.exe.
Installation will begin.
No product key is required.
Activation will be automatic.
For that reason I'll wait for the Windows 10 Anniversary Update that surely will come integrated into a Windows 10 ISO.
