Cannot open .MSC files

Okay, I'm using Windows Vista Home Premium. Last night I went to go to Computer Management (right-click on Computer and click Manage) and I get dialog box asking how to open the file (what program to use and all that jazz). Now I cannot open .MSC files. Anyone know how to fix this problem?

 

Well as always it doesn't hurt to do the READ & RUN ME FIRST and Basic Computer Maintanence everyone should do.

After that, run from your Vista disk;
chkdsk /r

Then boot to Safe Mode and run sfc /SCANNOW

 

Okay, I do all the stuff in those guides already. I believe it was CCleaner itself that deleted the .MSC extension because it was "unused" so it says.
I'll try the suggestions you offered and get back to you on the results.

 

@Drizzles: I ran the chkdsk and then booted to safe mode and ran the sfc but it didn't help. But no worries!

@DomLuc: I do registry backups every time and luckily I was able to search through the file contents of all my registry backups and found the file where it was deleted the first time, readded the contents of that backup, and blam, it works! Much thanks!

Problem solved! Thank you both for your help!

 

Agreed

 

Every post I've ever seen about CCleaner says it is safe to use, and in my experience that is so, but I shan't ever be running it again without taking the backup option :-o

 

SOLVED FOR ME.
I had the same problem and spent hours trawling the net. Some of the solutions are mind numbing.

Cut and paste this link:

Although it states XP, I used it on my Vista Home and, Bingo.

 

I have the same OS as you and have had the same problem. Seems to be a glitch with the registry cleaner in cCleaner, you have to uncheck file associations when running.

Fixing is easy. Start..Control Panel..Associate a file..set your default programs. Highlight the .msc file, click change program, find Microsoft Management Console in c:\windows\win.sxs and choose that.

Are you using the latest version of ccleaner because I think, maybe, this has been fixed?

 

Checked the file assoc - shows mmc. Maybe its because I used the registry fix provided by Doug Knox.

Thanks for your time.
ps. just downloaded the latest cCleaner and unticked the ms management box - just in case

You're welcome. I don't know what you mean by the MS management box. I prevent this problem by unticking the "unused file extensions" in the registry cleaner. Just FYI.

Happy surfing!

 

In CCleaner
Applications/Windows/MS Management Console - Untick box
ok
