Looks like a .NET Framework update ... you should probably leave them alone.

These if i'm not mistaking come everytime you get an update from Microsoft update . Like the person b4 me .... Should not touch them .

In reviewing the list, you have English as the language on the left side of the screen and Portuguese on the right side of the screen. Do you actually download files in Portuguese? I see the one file for a Windows update, but other than that, things seem unusual with an intermixed use of 2 languages.

Usualy when you have to give permission to a file ........ Is with a external Hard drive ..... No ?

The permissions issue can be with either a directly attached drive or with an external drive, depending on the file.

Could you please reply to my prior post regarding language.

HTH

it's better not touch them so , thanks!!

better leave them alone , other people also answered they are related to updates, so
