Advantages of Microsoft Windows over Linux
Easy To Operate - Microsoft has made several advancements and changes that have
made it a much easier to use Operating System, and although arguably it may not be
the easiest Operating System, it is still Easier than Linux.
Software Availability - Because of the large amount of Microsoft Windows users, there
is a much larger selection of available software programs, utilities, and games for
Windows.
Help - Microsoft Windows includes its own help section, has vast amount of available
online documentation and help, as well as books on each of the versions of Windows.
Compatibility - Because it’s backed by Microsoft, Windows typically has the jump on
Linux systems when it comes to compatibility with brand new hardware. This is because
Linux’s community of developers don’t usually have access to new hardware before it
comes out and Microsoft, with its powerful corporate backing, often does. So, Windows
tends to sync up better, and more conveniently, with brand new hardware on the
market.

Use the Permissions list box to grant or deny access permissions.
mind:

Read is the only permission needed to run scripts. Execute permission doesn't matter.

Read access is required to access a shortcut and its target.

Giving a user permission to write to a file but not to delete it doesn't prevent the user
from deleting the file's contents. A user can still delete the contents.

If a user has full control over a folder, the user can delete files in the folder regardless of
the permission on the files.
