Windows 11 vs Windows 10: Main Differences

Still sitting on the fence about upgrading to Windows 11 because you don’t know what to expect? Interestingly, the new edition somehow manages to be both a total revamp and still very similar to its predecessor in many ways. It’s really something to experience for yourself.

We do want to give you a sneak peek, though. So here’s an overview of the biggest changes Windows 11 brings to the table.

What’s different in Windows 11?

1. Visual changes

The first thing anyone will notice after switching to Windows 11 is the striking visual difference. The entire interface is smoother, cleaner and more minimalistic than on Windows 10, even resembling the macOS in some instances.
Perhaps the most obvious change in appearance is the Start menu and Taskbar location, which is now at the bottom center. It’s actually very neat, but if you’re someone who loves familiarity, don’t worry, you can move it back to the left.

Moreover, you’ll notice that the Taskbar includes a Microsoft Teams icon by default (which you can, of course, remove) and that Live Tiles are gone. The News and Interests section has also been removed - or, shall we say, replaced. As opposed to Windows 10, news, weather forecasts and other information are now displayed as widgets.

To add to the cleanliness of the UI, Microsoft also enhanced the ‘Snap Layouts’ feature to help you better organize your windows and maximize screen real estate. It’s similar to app grouping on your smartphone. In Windows 10 this feature is slightly restricted, as it requires some manual resizing and dragging. In Windows 11, you can just hover over the minimize/maximize option on a window, select a layout and throw the windows in there.

2. New accessibility features

Microsoft has certainly paid attention to accessibility with Windows 10, but Windows 11 takes this to a whole new level.

One of the ways Windows 11 has taken things up a notch is by adding the long-awaited ‘Live Captions’ feature and advanced Narrator options.

Live Captions apply both to media played on your PC as well as your own speech when you’re using the microphone. Keep in mind that, as with almost all kinds of subtitles, you have to be prepared for a potential delay. However, it’s barely noticeable and doesn’t take away from the usefulness of this awesome new feature whatsoever.

As for the Narrator, there are three new voice packs to choose from. Microsoft has tried to put emphasis on a more natural voice than we are used to. So, now you can choose between Aria, Jenny and Guy, who will read pretty much anything off your screen out loud. Aside from this, Microsoft has also expanded the list of braille displays supported by the Narrator feature. 
For users with anxiety or trouble concentrating, a welcomed addition is the Focus app, which is no longer part of the Clock app. It’s now separate and called ‘Focus Sessions’, automatically triggering the Do Not Disturb mode when activated. It blocks all pop-ups and flashes and lets you work in peace until you’re ready to switch it off.

3. Android apps

Android users may rejoice! Windows 11 supports the use of your favorite applications now. 

Microsoft has done this by integrating the Amazon Appstore to the Windows 11 Microsoft Store. From there, you can download your favorite Android apps and use them on your PC in a smartphone-like window.

Windows Subsystem for Android™️

Unfortunately not too many apps are supported at this time, but Microsoft is working on making the emulation possible for many more. Also, the option is only available in specific regions at this moment - check out if you’re one of the lucky ones.

4. Improved gaming performance

Avid gamers will be happy to hear that Microsoft has put some effort into streamlining Windows 11 for their gaming needs.

To give gamers a supreme visual experience, Windows 11 offers the ‘Auto HDR’ feature. As long as your monitor is HDR-compatible, this feature will automatically adjust the colors, brightness and contrast of games without any input from you. 

Another update is DirectStorage, which we were introduced to in Windows 10 already. In Windows 11, it’s been improved to tweak loading times and overall gaming performance efficiency even better. The predisposition for it to work optimally is that your device has an NVMe SSD. 

The Xbox Game Bar also helps gamers towards a smoother experience. It allows in-game screenshots, viewing processes that are running (similar to the Task Manager), monitoring the CPU and GPU performance and frame rate, integrating the Xbox App and more. There’s also a number of widgets you can now use with the Game Bar, for example the Spotify widget.

Another cool addition is the Xbox Game Pass, which unlocks hundreds of games to play on your Xbox App, with new additions coming in every month.

5. Smart App Control

Aside from a sleek new look and better accessibility for all users, Windows 11 also comes with a security power-up. Bear in mind that this feature is only available on clean Windows 11 installs. 

Smart App Control (SAC) is an AI-powered new feature designed to protect your PC from potential threats. It blocks untrustworthy apps and adware and helps detect potentially unwanted apps, maintaining your PC’s performance and keeping your system safe.

It comes with an ‘Evaluation’ mode, which you should definitely select when running SAC for the first time. That way, the app monitors your usage and assesses whether you’re a candidate for SAC. Some users need it to be on all the time, for others it might be too distracting. Evaluation mode will turn SAC on or off based on your usage.

Don’t disable SAC again unless you’re absolutely sure you don’t need it, since reenabling it will require a fresh install. We recommend you don’t turn it off, as it is a neat feature protecting your data and files from malware at all times.

Summary

Have we piqued your interest in trying Microsoft’s latest OS? It’s a pretty exciting new iteration, but we’ll let you find out for yourself. We hope you like it!

Create Custom Views in Event Viewer
The Event Viewer in the Windows operating system is used to troubleshoot any computer issues. It is one of the most useful tools that keep logs of both security and system events. It also monitors for both software and hardware problems in the computer. This tool is the only one with amazing features that maintain logs about everything that’s going on in the computer system. It keeps track of all the information to the point where going over them will take a lot of time. Luckily, the Event Viewer tool now allows users to create custom views where you can set the filters and sort the data recorded to limit the information details to only what you’re interested in seeing. For instance, if you want to troubleshoot with one hard drive, you can just create a special custom view to display only the hard drive warnings in the security logs. This will save you hassle and time. Take note that the logs in the Event Viewer are divided into two main categories namely the Window logs and the Application and Services logs. You can just set the filter to the logs by their event id, specific date, and many other events when you have to troubleshoot some problem in your computer. So if you are trying to troubleshoot a problem in your Windows 10 computer and you’re checking the Event Viewer, read on as this post will guide you in creating custom event views in the Event Viewer. To get started, refer to the instructions given below. Step 1: Go to the Start menu and in the search box, type “event viewer” and then click on Event Viewer from the search results to open it. Step 2: After opening Event Viewer, click on Custom Views located in the left pane of the window. Step 3: Next, click on the Administrative events under the Custom View to create special log views. Step 4: Then on the right side of the window, click on Create Custom View to open the Create Custom View window. Step 5: There is a logged drop-down list under Filter. From there, you have the option to choose an appropriate predefined time or use a custom time range for your Custom log views. Step 6: After that, select an appropriate event level for your custom view. You have fine entry-level options to choose from such as critical event level, error, warning, information and verbose.
  • Critical – select this if you want to see the events that require your immediate attention in the custom view.
  • Error – select this if you want your Event Viewer to display the events that are less critical but hints at the problems.
  • Warning – select this event-level if you want to see the event with the potential problem but may not bound to happen.
  • Verbose – select this if you want to see detailed information about all the events.
Step 7: After you’ve selected the event level, you now have to select how you want the events to be filtered. They can either be filtered By the log or By the source.
  • By the log – you can select two options called Windows log and, Application and Service logs. The Windows logs allow you to filter the logs created during events like setup, security, applications, and system events. While the Application and Service logs filter the log created by the installed applications in your system.
  • By the source – select this if you want your Custom View to search for information in event sources. It allows you to view events in detail for various applications and devices.
Note: You have the option to further customize the event logs with more filters like Event IDs, task category, keywords, User, and Computer. Using these additional filters, you can choose to filter the events in the special views by specifying event id numbers in the Event IDs, entering predefined Windows words in the Keyword, specify the user accounts in the User field, as well as choose the system from the server to maintain logs in the Computer field. Step 8: Once you’re done customizing the log filter, click on OK to apply the changes made. Step 9: After that, a Save Filter should be displayed in the Custom View window. Just enter the Custom View name and select the Event Viewer folder where you want to save the Custom view. The folder name should be Custom View by default. And if you want, you can also create your own folder if you want your custom views to be visible to all the system users. Step 10: Next, check all the Users box located in the lower corner of the window and then click the OK button after you’re done. You should now see the customized filter you just created on the left side of the window. Just click on it to check your filtered events in the center of the Event Viewer window. And for you to save the custom view logs, simply right-click on the Custom views you created and then click on Save All Events in the Custom View As from the drop-down menu. Then put a name on the file and select the appropriate location where you want to save the logs and click on the Save button.
