Hi,
I did something stupid and I need to fix it fast. I have created a text file and renamed it with .bak. Then I opened the file with Notepad and now all my SQL Server 2012 64 bit backup files are associated with notepad. How can I restore my original backup file program association which is Windows shell common dll ? Remember that it is 64 bit Windows 2008 R2 with SQL Server 2012 Enterprise Edition.
I can not see the "Change" button on the backup file properties anymore.
Please help.
