Featured Reviews

Shafiq Khan - PeerSpot reviewer
Head Of IT at a financial services firm with 1,001-5,000 employees
Long-term server platform has supported secure banking operations and simplified virtualization
Oracle Solaris is a very good operating system. Most of the time, we do not need to change or replace any configuration. If at any point in time we need to change something, it is really simple and a user-friendly environment. Although it is a CLI, Oracle introduced a GUI environment with Solaris 11.5. Currently, 11.5 has the operating system GUI as well as the CLI. The technical persons working on the operating system most of the time prefer to work on the CLI. It is actually really good and easy to use. As it is a server-level operating system, most of the time you do not need any extra features in the operating system because you are not using the operating system on home machines, desktops, or laptop machines. The extra features are not needed if we are talking about the enterprise level or an official operating system.
Naveenkumar Lakshman - PeerSpot reviewer
Presales Engineer at Crayon AS
Daily work has become smoother and organized as I manage calls, notes, and files efficiently
The best features that Windows 11 offers in my opinion are Notepad++ and the integration, as I could use Microsoft 365 on it and I could also run many applications. If I want to use Linux, then I could use Windows Subsystem for Linux as well. Most of the industry-wide applications are easily installable on Windows 11 and user-friendly as well. Windows 11 has definitely impacted my organization positively because you could see that all the day-to-day activities, most of our professionals would use a Windows system itself. In terms of productivity, Windows 11 has made a positive difference as we use a mail inbox with its links and Microsoft Teams, which is available. Windows 11 is natively installable and very friendly with the compatible operating system, and alongside, we have other applications that are available. Edge browser, which is the default browser for Windows 11, is also a good browser and a very decent option. Additionally, we have other features available for the day-to-day activities. You can see it gives you a basic calendar, calculator, and camera options, and you have the File Explorer. You get a pretty decent operating system for a layman to work on a day-to-day basis. While there are certain tasks that consume a certain amount of time, Windows 11 reduces the time. The usability and architecture, how it is built, makes a user get into a state where they don't need to spend excessive effort on the task to be done. You can get everything through a UI-based interface, and everything is sorted and very simple. Over the period of time, the operating system evolution by Microsoft is good for the individual workspace.
