Device frequently disconnects from hotspot

Default applications in previous Windows versions were a pretty straightforward process. The user went to the settings application and picked for each category which application he would like to choose from the list of installed ones. In Windows 11 things are little changed. In this article, we will show you how to choose the default internet browser inside Windows 11, and sadly it is a more tedious task than in previous versions.

Choosing default browser in settings

As in previous versions of the Windows operating system you will need to use the settings application in order to change your default Internet browser. Previously, in Windows 10, a variety of general categories like email, web browser, and photo viewer were all listed under the Default Apps section of the Settings panel. It was easy to click on one of those categories and click on the option you like best from the small pop-up suggestion window. In the Windows 11 Insider Build, you’ll see a gauche list of an individual file or link types that you’ll need to specify your preferred browser for. The types include: HTM, HTML, PDF, SHTML, SVG, WEBP, SHT, FTP, HTTP, and HTTPS. There are additional optional types you can specify your preferred browser for as well. The issue here is in order to use a single browser which most users do you will have to go through each file type and set your preferred one. I am really not sure why this was introduced or why it has to be this way, all I can do is hope that in the final release of Windows 11 this feature will be rolled back as it used to be and that you could set your default browser in just one simple click.

When we purchase a computer, usually it is meant to be used by one person. Sometimes we would like to share our computer with other people, with friends and family members but we would also like to keep some privacy for ourselves in the process. Lucky for us Windows 10 will let us create multiple user accounts which then can be used by other persons with their own settings, documents, etc. The only requirement is to already have one user account which is automatically created when Windows is installed. This guide will lead you step by step in the creation of a new user account within Windows 10, so grab your favorite drink, and let's begin.

Creating new account

First thing is to click on the windows icon on the bottom left and open start menu, from start menu click once on settings. When the settings window opens, choose ACCOUNTS on it. Windows will then go to the accounts settings page. Within that page, click on the Family & other users to open the setting for the chosen section on right. On the right settings, screen navigate to the lower section and click once with the left button on add someone else to this PC When add someone else to this PC is clicked, pop up window will appear which will ask you to provide the persons email address and later on the password of his/her Microsoft account, after the required information is provided you are done, a new user has been added and he can use his Microsoft credentials on the login screen to use this computer.

Setting up a user without Microsoft ID

However, if you do not wish to add a new user via his Microsoft login credentials or the person does not have them, on the pop-up window click on I don't have this person's sign-in information. This will open yet another pop-up giving you the option to create a Microsoft account for this person, to use a phone number instead of a Microsoft account, or to create a new email address for the user. Any of these options will create a new user for this computer with provided credentials but there is the last option at bottom of the pop-up which will allow you to create a local user only without a Microsoft account. This user will be able to use this computer, will not be able to transfer his document through various devices like he/she would if using a valid Microsoft account but it could use the computer and personalize it fully to his/her liking. Once the link is clicked, you will be presented with a floating window requiring you to input needed information in order for the account to be created. You will need to provide username, password, and answers to 3 security questions. Once all information has been provided, click on next and your new non-Microsoft local user has been created. Now when you click on Family & other users you will see that Windows has added a new user with the provided name to this computer. If you wish, you can add another user in the same manner, following the previous steps. Microsoft Windows does not have a limit for how many users can be on one computer so feel free to create as many as you like.

User account options

Now, clicking on the existing created user will open user options. From there you will have options to remove the user, therefore removing him/her from this computer, note that removing the local user will remove permanently his/her settings and they would not be able to be restored, or you can change the user account type. Click on Change account type. Under account type, you will have the option to promote this user to an administrator if you wish or you can leave it as a standard user.

About Potentially Unwanted Applications

You have encountered it – you download a free application, then you discover some unwanted applications on your computer or discover a strange toolbar has been added to your web browser. You did not install them, so how did they appear? These unwanted programs, which are called Potentially Unwanted Programs, or PUPs in short, typically tag along as a software bundle when downloading the application and can result in major problems for computer users. The idea of PUP was actually coined to outline this crapware as something other than malicious software. This is because, the majority of PUPs get into a computer not because they slip via the security holes, for instance, but mainly because the users have installed them themselves – 100 % unintentionally needless to say. Even though a PUP isn’t really malware by definition, it could nevertheless be dangerous software that puts the computer at risk exactly the same way a virus does.

Exactly how do unwanted programs look like?

Unwanted programs can be found in many forms. Typically, they could be found in adware bundlers which are known to utilize aggressive and misleading advertising. The majority of bundlers install many adware applications from several companies, each of which has its own EULA policy. Safebytes Anti-malware completely eliminates this threat and protects your machine against PUP or adware infection. Also, the majority of free programs nowadays come with a few unwanted add-ons; in most cases a web browser toolbar or browser modification such as a homepage hijacker. They may track your online routines, redirect your search results to unsafe websites where viruses can be downloaded and installed, hijack your search page, and slow your browser down to a crawl. PUPs lie inside the gray part of the software spectrum. Some PUPs contain keyloggers, dialers, and other software to gather your individual information which often can lead to identity theft. These are software programs that don’t really do anything useful to you; in addition to taking over space on the hard disk, they also slow down your computer, often alter settings without your permission, and the list of bothersome features goes on and on.

How one can prevent PUPs

• Read carefully before agreeing to the license agreement as it might possess a clause about PUPs. • Always pick the custom if you’re provided a choice between Recommended and Custom Installations – never click Next, Next, Next blindly. • Install reputable antivirus software, just like Safebytes Anti-malware that offers real-time protection against PUPs. • Do not download free applications or shareware unless you actually need it. Disable or remove toolbars and browser extensions you don’t actually need. • Always download software from the original site. The majority of PUPs find their way onto your PC is via download portals, so steer clear of it entirely. Remember that although PUPs can cause damage and hinder the proper functioning of your computer, they can’t enter into your computer without your permission, so be watchful not to give it to them.

Hello and welcome everyone, today we will be talking about dreaded keyloggers, why they are dangerous, and how to know if you might have one in your system. Keylogger is a malicious application placed in your system and hidden with only one goal in mind, to get information about what are you typing and by that means for a person who infected you to get information about your credit card information or other sensitive data. They can be introduced into your systems in various ways and often can not be detected easily. Modern antivirus applications have ways of detecting them and removing but this tutorial aims to teach you how to spot them all by yourself since new keyloggers are produced daily and sometimes relying on antivirus alone is not enough. Unlike viruses and trojans, keyloggers are not heavy on system resources and you will not feel slow down on your computer if you have one which makes them harder to sport with regular work. Some of them can be even tracking you on the website and not even be physically present on your computer. Generally, we could categorize keylogger into 4 categories:

1. Web browser-based keylogger. Some websites would have CSS scripts, input web forms, or so-called man in the middle keylogger. Lucky for us even Windows defenders with the latest update can detect this type of keylogger and successfully deal with it and how keylogger itself is not present on our system we are safe.
2. General spyware keylogger. This keylogger is present in your system, usually, it infected it via email attachment, social media download, torrent download, some malicious so-called fixer application, etc. Most antivirus applications and windows defenders can detect these types as well and remove them successfully.
3. Kernel-level keylogger. This keylogger is a more dangerous type they tend to operate underneath Windows as a rootkit and can go undetected by antivirus and windows defenders.
4. Hypervisor-based keylogger. This is the most dangerous keylogger, they use virtualization techniques to hide and mask themselves as a replica of the operating system and they scan all keystrokes by the user. These are very rare keyloggers but they do exist.

If you suspect that you have a keylogger or just want to check your system for precaution reasons follow these tips and guides and luckily you will solve your issue in no time and your data will be safe.

1. Use Task Manager to find suspicious entries.

   Task manager is a great application implemented in Windows that is constantly monitoring and showing all services, applications, and processes currently running on your system and thus a great tool to monitor your system if you know how to use it. First, open task manager by pressing CTRL + SHIFT + ESC Then take a good look into it, try to find suspicious names, probably duplicate of running application, something like Windows logon application, or keylog or anything similar which seems out of ordinary. If you manage to find a suspicious running application right-click on it and close it. Also while you are in task manager jump into the startup tab and check to see are there some unusual applications starting with your Windows, if you find anything, disable it right away. This is the most simple and quickest way to get some information right away if you suspect to have some simpler keylogger in your system.

2. Use the command prompt to monitor your network.

   In order to check connections to your computer and find potential suspicious ones start the command prompt in administrator mode, press ⊞ Win + X, and choose command prompt (administrator). type in netstat -b and press ENTER. All website and application connections to your computer are now visible. ignore svchost, edge browser, windows store, etc ad check the IP of the remaining ones using the internet.

3. Use keystroke encryption.

   Install encrypting software and even if you have a keylogger, the application will encrypt each stroke and all that attacker will get is gibberish

Please remember to always download files from trusted sources, do not open unknown emails, and do not share your information publicly. Take common protection steps in order to protect yourself in the digital world.

Windows and Devices chief Panos Panay has revealed new focus sessions feature that will be in Windows 11 on his Twitter account today. He himself is referring to it as a game-changer especially with Spotify integration.

So what is a focus session?

From the video clip provided on Twitter, we can see that focus session users will be able to choose a specific task from the previously made task list, choose songs that will play in the background while the task is active, and set a timer for the chosen task with breaks. Maybe the best comparison and explanation would be a desktop google calendar task with music, basically, that’s it. A neat and good organizer inside your Windows 11 operating system. I think that this is generally a good idea and for sure it will find its audience.
