Windows 10: Restore Default File Type Associations in Windows 10

Hello! Is there a way you could add a zip file or something at the bottom of the first post, so we can download ALL those .reg files?
I like to have a USB stick with me for PC repair, and it would be great to have these in a folder for when needed. Thanks for considering it!

 

Hello @wintendo, and welcome to Ten Forums. *Smile

I added a ZIP file above the table in OPTION TWO that contains all the downloads to help.

 

I have video files (AVI and MPEG) created by an old version of Pinnacle Studio. Each file has an accompanying SCN file which contains info for the video clip. I accidentally changed the default app for SCN file from "unkown file extension" to "Notepad". I've reset apps to defaults and even done a registry edit (which works on XP and 7 but not windows 10).

How do I restore default associations for SCN files?

 

Hello gainzer, and welcome to Ten Forums. *Smile

If you like, the .reg file below will unassociate .scn files for you.

Unassociate_SCN.reg

 

F--king thank you!
I thought I was gonna have to do a complete system restore, but now I'm good.

 

You're most welcome. I'm glad it could help. *Smile

 

Ok, problem again. The clips were working right after I downloaded the unassociate file and merged...
Then I re-installed the Pinnacle Studio 9 (I had un-installed it first to try to fix the scn problem).
Now the clips are back to the same "Windows Media Player has encountered an error" message and "Can't play" on Movies and TV.
After the first time I installed the program I'm pretty sure the playback was still fine on all players.
I didn't have a problem until the change to the scn files. Since then I can only watch the clips inside the video program itself.

After using the un-associate file, SCN is no longer listed in "default apps". But in the registry it says...

(Default) REG_SZ {value not set}
a REG_SZ {1AC14E77-02E7-4E5D-B744-2EB1AE5198B7}/Open...
MRU List REG_SZ a

Is this entry a problem? What if I delete the second line?

Or could the problem be with the Pinnacle program itself?

Any help will be appreciated.

 

Let's go ahead and see a screenshot showing that registry location before deleting it to make sure it's safe. *Smile

I don't know how to make a screenshot but the location is here...

I go This PC>Local Disk C:> Windows and then select "regedit" from list and then....

HKEY_CURRENT_USER/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/FileExts/.scn/OpenWithList

 

The Unassociate_SCN.reg would delete that registry key for you if you would like to merge it again.

 

Ok so I merged it again and it deleted the scn extension completely from the registry. Now I've also noticed some suspicious .com registry entries with lots of numbers behind them?

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.com/search?q=scn+file+format&form=WNSGPH&qs=AS&cvid=58e37ee2ec8a467db2523cac7dd60228&pq=scn%20file&nclid =5CB529757CF671B3E8F9E49B659C961C&ts=1458857854896&nclidts=1458857854&tsms=896

What the hell is that?^

Are these fixes official? Why doesn't Microsoft have something to fix this crap? All it took was one accidental click in the wrong box and I'm wasting hours of my life and f--king up my computer trying to fix it?

 

I wouldn't worry about the .com stuff.

Are you .scn files ok now?

If not, then you could do a system restore using a restore point dated before you changed them by mistake to undo and fix it.
