It is faster to do things On MS Windows:
When the GUI is installed, it is really great. For instance, setting up a VPN is extremely quick to do & it works right away. Ms. Windows modules are aware of the other modules, so they install missing modules for you and/or modify other modules for you. When you remove them, they don't hurt the system. On the other hand on Linux, you have to get the configuration files working right away.
It is easier to configure MS windows server:
If you setup a VPN on Linux, it is easy to install OpenVPN. Nevertheless, the configuration is always difficult. For instance, with OpenVPN, you will perhaps have issues with Iptables and the "forward" table. there are many modules you have to consider. Today, windows server 2012 modules are aware of the firewall, NAT & routing. its creates the necessary rules for you.
With Windows, you need fewer people:
Since it takes less time to do a task on MS Windows, you can hire fewer people to the same tasks than on Linux. So, you pay a pricey license but after that, you can work so fast and deploy many modules very quickly (a web server, a mail server, a file sharing server, a VPN...)
Problem with username: groups in Linux:
Numerous times, I had problems with Linux programs that modified username and groups, making programs unavailable. in the Windows server, it never happened. The users and groups are complicated in windows server but it works.
Windows server is more secure:
Did you hear about OpenSSL heartbleed? The Linux geeks didn't talk about the level of such a weak point. OpenSSL is installed on all Linux platforms. All the Linux versions were impacted by heartbleed. OpenSSL is THE package that handles SSL protocol everywhere. It is used for https, SSL over VPN, secure SMTP, IMAP, sshd !!! It is HUGE. More importantly, I had once a virus on Debian. I have tried everything to get rid of it but the virus had modified so many system files that I had to re install the OS.
Open projects, Open source & accountability:
Some open source projects have very few money. You don't who is behind the projects. Also since it is open source, there is no accountability behind projects. People say that if the heartbleed vulnerability appeared it was due to the fact that the OpenSSL project didn't get enough donations. If you have a company and if something goes wrong because of Linux, you will discover this aspect of Linux but it will be too late.
Backup:
It is easy to setup a backup strategy in Windows & it is easy to restore windows backup too. You don't need to be the PowerShell specialist when you turn on the GUI. On the other hand, if you want an incremental backup on Linux, good luck with the command line. But wait, why do we spend so much time with one command line?
Windows Updates:
We are so much used to it so we think it is normal but Microsoft updates are a great thing. The system is able to update itself without endangering the system. I've never had any problems with any Microsoft updates on any windows servers. On the other hand, with Linux, I always sweat after updates. In Linux, there is less continuity than with Microsoft programs. For instance, when I updated MySql from 5.5 to 5.6 on my Centos, it didn't restart because my configuration file wasn't good anymore. This would never have had happened on a Windows Server. After migrating to Apache 2.4 on my Centos, I lost my configuration file. This would never have had happened with IIs.
GPO (Group Policy Object):
It is a repository that allows a lot of good things for the administrator. Let me give you an example. A long time ago, a user stole sensitive documents thanks to a USB drive. With the GPO on the main server in less than 10 clicks, I forbid the USB access on 50 computers from Active Directory.
Also, thanks to GPO, you can install a software on all clients. It means that the server has the path to the distribution file and when the client computers reboot they automatically install the software.
Linux installation is fragile:
Once I had a Raid 5, I didn’t know the boot sector had to be rewritten after replacing a drive.
My testimonial with Windows Server Vs Linux:
On the paper, I think we can always do the same things in Linux than on Windows. However, I prefer to work with windows when I have the opportunity to do it because it is less workload for me and I can sleep. As Network administrator, I have faced my biggest issues with Linux. The kind of issue, that make you go to bed at 3 am in the morning.

1. Cost: It is an open source, hence it is free. Unless you are running a server in an Enterprise level for that you need Red Hat Linux license but apart from that, it is free. You can download the OS from its official site.
2.Stability. Most of the Enterprise use Linux because OS doesn't hang at all. Linux can run for years without a glitch(longest I have heard is 14 years without reboot)
3. Flexibility: Unlike windows where all the installation of windows falls under the single partition and if some error occurs if you have to install windows again most of the time, but in Linux, you can keep Linux file under multiple partitions. So even if one partition gets corrupted you will have to repair a single partition without hampering another file on other partition.
4. Security: Its malware free. You will not require to install any anti-virus program and keep on updating it.
5.More Security: Since to use Linux you should have knowledge of commands. Graphical interfaces make OS easier to navigate even for those who are not familiar with command lines but with Linux, navigation becomes difficult. If you fire wrong commands you might screw up your system.
Hence to get the best of Linux you have to have knowledge of commands.
6. Hardware: Linux is perfect for those old computers with barely any processing power or memory you have sitting in your garage or basement collecting dust. Install Linux and use it as a firewall, a file server, or a backup server, Router etc and list can go on. With windows, you need to purchase Windows Server edition to do these stuff.
7. FREEDOM: The vast majority of Linux software is a free and open source. Not only are you getting the software for no charge, but you have the option to modify the source code and add more features if you understand the programming language. What more could you ask for?
