The /proc file system is used internally by the Unix and Linux operating systems.
Unix and Windows do things differently; Windows uses the registry, which in a sense is what the /proc file system does, but in a different way.
Operating systems are all different; they are free to implement ideas and details in any way they want to.
If you are asking about the Pro*C compiler, that's a different matter.
A Unix shell can be obtained in Cygwin, a Unix compatibility layer used to compile Unix programs and run them on Windows. Microsoft also makes a shell known as "Windows PowerShell" which incorporates more Unix-like features than the standard command prompt.
Unix is used very similarly to other operating systems (Windows, etc.) for their applications.
In Windows and Unix-based and Unix-like systems, the command is mkdir (however in Windows a shortcut md can be used as well).
There are Windows Server, Linux, BSD, and even Apple's own server
The question is rather vague; the applications used in Unix are similar or identical to those used in other operating systems, such as Windows.

Cygwin is used to port applications that were written for Unix or Linux to a Windows environment.
tar extension can more or less be compared to zip: a tarball (this is the name of a "tar extension'ed file") is used to group file (and eventually folders of files). Although tarballs are mostly used in Unix flavors, programs such as WinRar for Windows can extract files from them. In short, such drivers may work for both Windows and/or Unix flavors.
I know nothing about Unix but for windows there is the control+alt+deleat combination ants there is also the flag or windows key.
Unix and windows are two separate groups of operating systems. Windows is the operating system of about 90% of personal computers, while unix is the basis of many other operating systems, such as Mac OS X
