Microsoft Office Windows 11 edition

In case you don’t know, there is a feature in Windows 10 computers that allows them to function a lot better. This feature is called Full-Screen optimization and it is enabled by default for several applications such as games and video players. If enabled, the Full-Screen optimization feature enhances the video playback and gaming by simply putting the CPU and GPU process as a priority. However, there are times when it can also result to a drop in the frame rate or FPS while in full-screen mode. And of course, the obvious solution to this dilemma is by disabling the Full-Screen optimization feature which is why Microsoft took action and removed this feature themselves in the recent Windows 10 Update releases. However, there is another way for you to enable it back or disable it yourself if you haven’t installed the recent updates yet and there are plenty of ways you can do both. All you have to do is follow the options given below carefully.

Option 1 – Try using Windows 10 Settings

If you haven’t installed the recent updates yet and all you have are the earlier releases, then this method would suit you.

• Open the Windows 10 Settings app.
• Next, navigate to System > Display > Graphics Settings or Advanced graphics settings.
• From there, uncheck the “Enable Fullscreen optimization” option if you want to disable the feature, else just keep it checked.

Option 2 – Try using the Registry Editor

• Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Afterward, if a User Account Control or UAC prompt appears, click on Yes.
• Once the Registry Editor is pulled up, navigate to this registry key: HKEY_CURRENT_USERSystemGameConfigStore
• Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name it to “GameDVR_DSEBehavior and tap Enter to save it.
• Now double click on the newly created GameDVR_DSEBehavior DWORD and set its value to “2” if you want to disable it, or “0” if you want to enable it.
• Once you entered the value, close the Registry Editor and restart your computer to successfully apply the changes made.

Option 3 – Try running the application in Compatibility Mode

If the first two options didn’t work, the next thing you can do is to run the application in a Compatibility Mode. Follow the steps below to do so:

• Go to the location of the application or game on which you need to disable or enable the Full-Screen optimization feature.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you can see the “Disable fullscreen optimization” option to disable the feature and vice versa.
• Now click on the Apply and OK buttons to apply the changes made in the application’s settings.

Today most people have Facebook accounts where they keep in touch with friends and family. But large Facebook network of users is also very interesting to another party as well, hackers. There are many ways hackers can steal your data via direct hacks, trickery, and social engineering in order to get your credentials, emails, and many other things using them to wreak further havoc. Once a hacker has needed information it is very difficult to minimize impact and all of your information could be compromised from a list of friends to credit card numbers. Keep on reading to learn how can you protect yourself against these attacks and learn about common practices that hackers use in order to steal your data.

Stealing Facebook data via email

A couple of years ago there was a lot of talk about not opening suspicious emails. Well, it still holds today. The difference is that today’s fake emails have become very difficult to differentiate from official ones since hackers put the effort into creating them copying fonts and layout, making them identical to original ones. So if emails look and feel like original ones how do you know if it is fake? Very simple, you do not click anything in it. If Facebook or for that matter any company wants to contact you they will do via their platform. Clicking inside a hacker's email will lead you probably to a fake Facebook website replica where you will have to type in your username and password providing an attacker with your login credentials, etc. If you receive this kind of mail where there are threats about terminating an account, missing payments, etc. it is always the best thing to go directly to Facebook and see if you have any kind of notifications there. Do not trust any emails that ask for account information, request money, or threaten to suspend your account.

Phishing attacks

As stated previously if you click on the link inside fake mail it will probably lead you to a website replica of the original. Although hackers can pretty much copy all things from an original website like layout, fonts, colors, etc. There is one thing that he cannot, web address. Take a good look into your browser address bar to see if there is a typo or anything strange in the address of a website. Also, make sure to check for the secure icon in the web address before signing in.

Fake Facebook buttons

If by any chance and for whatever reason, you end up on a fake Facebook site be vary careful about like and other buttons since buttons themselves behave and act like links inside your browser. IF when you click on like you get a prompt to sign in, it is almost 100% that you ended up on a phishing fake website.

Password brute force attack

Having complex and long passwords is a must. If your Facebook password is 12345 there is a very high chance that if a hacker wants he can easily guess it via trying out the most used and simple passwords via simple guessing. To avoid being hacked just for having poor passwords try to think of something longer, combine letters and numerical characters, place special characters inside it or just simply as the best solution use a password manager and create passwords with it.

Password grab outside Facebook

If you use the same password for multiple accounts which is a big no-no and you should not do it then hackers can use passwords from other services and login into your Facebook in order to steal data. Avoid these situations by having different passwords for different accounts or use a password manager to keep everything in order.

Hacking via key logger

Some time ago we have made an article which explained in detail everything you need to know about key loggers here: https://errortools.com/windows/how-to-know-if-you-have-keylogger-in-windows/ Anyway, this is a more advanced hacking technique in order for hackers to steal your data and it includes placing malicious applications into your system that records your keystrokes and sends them directly to hackers. Since this is an application best protection against this type of attack is to have a security suite installed and active on your PC or device you use to go to Facebook.

Connecting and surfing on an unsecured network

Using no password and unsecured WI FI or any other type of network is risky at least. You can have all protection installed on your device and have a strong password but hackers also logged in to the same network can track all outgoing stuff going through mentioned network leaving you again exposed to attacks. It is better to connect to your mobile operator network than on free WI FI, at least there is some level of security in your operator network while free WI FI is completely unsecured. Getting a virtual private network or VPN is also one thing you could think about for protection since almost all VPN services will encrypt your data thus providing you with a security layer even on unsecured Wi-FI.

Conclusion

Hacking and stealing have come a long way from their infant stages and in today’s world when we use a lot of gadgets and have plenty of online presence taking some steps for security is a must. I hope that you have found anything here informational and helpful so you can avoid getting your data compromised.

Despite popular belief, there are a lot of users running Linux OS. Linux offers great security and working environment and 96.3% of the world's top 1 million servers run on Linux. 90% of all cloud infrastructure operates on Linux and practically all the best cloud hosts use it. But gaming on Linux is limited, enter Steam proton a Valve’s gaming solution.

What is Steam proton?

Proton is a WINE fork with some extra capabilities, to play games and run applications not native and not made to run natively under Linux OS. It is supposed to bridge the Gaming issues for PC users and let them more freedom in choosing an operating system to game on.

Find out if your game supports Proton

Although there are a lot of titles that nowadays run natively on Linux some will still need proton in order to run at all and sadly some of them will not be able to run on Linux even via proton but seeing how Valve is busy and it is trying to push its ideas and technology slowly this gap is closing. In order to see how the game you want to play performs and behaves on Linux and proton environment visit https://www.protondb.com/ and find out. As soon as the site loads you will be greeted with statistics and a search option to find out the status of the desired game with one of the given statuses: Borked, Bronze, Silver, Gold, Platinum, and Native. As you probably guessed native means that the game will work on Linux out of the box and borked will probably not work at all. Platinum and gold status means that game will run on proton without any input or tweaks from the user while silver and bronze means that it will work but might need some tweaks in order to make it work.

How to get Steam proton?

In order to run games under proton inside Linux, you will need firstly a Steam client which luckily works naturally on Linux. Unlocking/activating Steam Proton on your Linux-based system is easy. Just head over to Steam > Settings > Steam Play and toggle the option “Enable Steam Play for Supported Titles”. Valve has tested and fixed some Steam titles and you will now be able to play those titles. However, if you wish to go even further beyond, and play titles that even Valve has not tested, toggle the option “Enable Steam Play for all titles”.

Conclusion

Even we are not there yet, native gaming on Linux is gaining a foothold each day. Will Steam’s OS with proton technology be one that will turn the tide from Windows or some other tech we cannot tell but one thing is for sure, more choices mean better products so I am hopeful for a bright future.
