Windows 10: I have leftovers from uninstall

I installed Magix Sound Forge in the past and I am left with some leftovers. The only time it shows up is when I right click a mp3 file. I have uninstalled properly and have deleted files from the registry plus disk cleanup. It shouldn't be on this computer anywhere but it is. How do I get this taken off?

:)

 

Please help me remove a leftover of an uninstalled app

Please help me remove this leftover "item/registry junk" or whatever it is, from the "How do you want to open this file?" apps list. I uninstalled that software, but it is still in the list for opening my BDMV, M2TS, MPLS files. The wierd "leftover" just shows a location of an already uninstalled video player. I have marked the wierd phenomenon.

Thank you.
(I apologize, but I really dont know how else to explain. On another forum people had "problems" understanding longer sentences...I hope that will not be the case here too.)

 

How do you uninstall chipset drivers?

I'm installing a new mobo so I need to uninstall the intel 865g drivers to make way for the P35 drivers.

Can't find any uninstall options in add/remove programs and intel chipset inst listed in driver cleaner.

Any suggestions? *Confused

 

AVG leftovers

Hello,
Almost two months since I uninstalled this AVG antivirus using their special removal tool, then searched for leftover files and deleted them manually, did the same in the registry.
Recently while using CCleaner, noticed there is still an AVG leftover in the installed programs list, "Visual Studio 2012 x86 Redistributables".
Is "Microsoft Visual C++" the same, then I can remove this AVG leftover ?
Attached screenshot.
Answers will be appreciated
Thanks
