Trouble with file associations in Windows 10

this trouble in last 2 month only.

MS security by user injurity.

If you want to use software portably, it's a nonsense to attempt to use an operating system feature that requires specific software to be permanently installed.

Some, like me, use portable software not because I actually need it to be literally portable, but because I see no sense in losing all of my settings and files every time I need to reinstall Windows or update certain software. Up until the latest Windows 10 update, it was negligibly easy to set up file associations when needed, but now it's only possible via excruciatingly time-consuming and frustrating editing of registry keys by hand or by using 3rd-party apps like FileTypesMan, which now makes my particular use case for portable software more burdensome than just installing things like normal.

I don't expect PortableApps.com to cater to people like me and wouldn't presume to even request a feature for creating file associations for those who might want it, but some of us just use portable software for a simpler life, not because we're moving from PC to PC. I accept that we're probably in the minority, but we do exist.

If it's so important to you to be able to work around this Windows System Security feature then the only real solution is to use some software that maintains its own internal File Associations system separate from the Windows defaults; and which doesn't open (i.e. Hack) the system in a way which would allow malware or human intervention to maliciously alter user settings.

One example is the File Manager Multi Commander (available in a portable version but not from this site and not in PortableApps format). See http://multicommander.com/docs/filetypesetup for a description of its File Association system.

Please remember what you might see as a "BIG issue" is entirely irrelevant to the vast majority of Windows Users, who don't know anything about file associations and don't need to. They just want their system to be secure and to work as designed.

We're talking specifically about the ability to set/over-ride default application settings and what you are describing doesn't happen in Windows 10, which is specifically designed not to allow file associations to be set to applications that aren't installed 'correctly' according to Microsoft guidelines for security reasons; i.e. only user applications that are fully installed in the Program Files and Program Files (x86) Folders and can therefore be managed through Settings > Apps and Features are permitted to be set as system defaults, which is intended to prevent random unauthorised changes to existing system defaults by both malware and newly installed applications that love to make changes without asking for administrator permissions, but this also clearly has an impact on user intervention. It's a trade-off of increased system protection for the masses versus complete user flexibility for the experienced.
