How to Remove Write Protected Regular Files
Microsoft Windows operating systems ship with the Windows Explorer file management interface. Windows Explorer provides a tree view of folders and files and enables users to modify file attributes by accessing a "Properties" page for each file. When a file attribute is set to "Read-only," the file is write-protected and cannot be edited or removed. Using Windows Explorer to change attributes of certain files, write-protected, regular (non-system) files may be edited and deleted with little effort.
Right-click on the write-protected file to remove and select "Properties" from the context menu.
Uncheck the check box in front of the "Read-only" option and ensure the check box in front of the "Hidden" option is clear as well.
Click the "OK" button to save the settings and close the Properties window. The write-protection attribute has now been removed from the file.
Right-click on the file and select "Delete" to remove the file from the file system and send it to the Recycle Bin.
