Having a PC is a great thing, more often we are enjoying it than we have issues, but as time passes it seems that our computer is slowing more and more as new applications and games are coming which demand more powerful computers. Before you decide to throw away your computer and buy a new one because you feel it is a bit slow, read through this guide where we will guide you to common tips & trick to make your PC run faster:

1. Keep your PC clean and tidy

   Slowdowns and many other issues, even hardware failures can come from dirty PC. Make sure your PC is clean and tidy for maximum performance.

2. Optimize airflow through PC casing

   Airflow is very important so your GPU and CPU and overall all hardware components can be kept in optimal working temperatures. If any device inside the casing is working in abnormal temperatures you will experience slowdowns and freezing on daily basis. Make sure that all fans are working and that your temperatures are in the optimal range to prevent overheating and make sure to have maximum performance.

3. Check PC for malware

   Viruses, worms, and overall all malware can drastically reduce system performance. Make sure that your protection software is up to date with the latest definitions and that you have the latest Windows updates installed.

4. Create a Hi-Performance power plan

   Windows power plans can be a very useful feature, especially if you are working on laptop but in order to boost performance and drain maximum, you will need to switch to a hi-performance power plan.

5. Free space on the system drive

   Having little to no space on your Windows system drive can lead to extreme slowdowns, make sure that your hard drive is not on red when viewed from File explorer or you will experience even 50% poorer performance.

6. Choose startup applications

   If you have many applications starting up with your Windows and many of them running in the background you will experience performance issues. Each application that runs in the background is taking RAM and CPU time for themselves which could be free and used for the program that you need.

7. Do not open too many tabs in Browser

   Having too many tabs in Browser while working on a computer can also cause slowdowns, each tab is taking RAM for itself and even can cause Browser poor performance if a tab is LIVE and refreshing with new content all the time.

8. Remove browser extensions

   Speaking of browser, having too many installed extensions which are active as soon as the browser is up and running can also lead to poor performances. Remove all which you really do not need and your computer will gain in speed.

9. Make hardware upgrade

   Sometimes your system is just a little outdated, upgrading more RAM or switching to a new SSD with the greater speed can cause a world of difference in PC performance. Check to see how RAM is standard and upgrade accordingly, you can also upgrade the CPU and other bottlenecks in your system this way instead of completely buying a new PC.

10. Format and reinstall system

    Drives, application traces, registry entries, etc. are piling up in your system over time, and if enough time is given it will clog your computer. From time to time it is a good idea to backup files and do a completely clean full format of HD and install a new and fresh copy of Windows with new and clean copies of applications and drivers.

That's it, 10 tips on how to make your Windows and PC perform better and speed it up. I hope that you found the read informative and helpful and I hope that I will see you soon.

After Plex, DoorDash, and LastPass, Samsung has also confirmed that they also have experienced a data breach and that some customer data has been stolen.

On Friday, September 2nd Samsung announced that an unauthorized third party gained access to some of the company's U.S. systems in late July and that Samsung learned in August that some personal information was affected. It was also stated that affected information is: names, contact information, demographics, dates of birth, and product registration information. Also so far it was said that no Social Security numbers nor credit card number information have been compromised.

For now, Samsung is sending an email directly to anyone that has been affected by this data breach, however, they did not state what service or product has experienced this breach, we just know that it has happened at Samsung Electronics America which sells everything, from smartphones to debit cards. Also keep an eye on your inbox if you are a Samsung user since it took them a whole month in order to go public with this information and there is no justification for this, if it was reported on time people could change their information and take other steps.

If you are starting to get into the “wonderful” world of coding there is a high chance that you have heard of GitHub or Git for short and there is a slight chance that you might be confused about what exactly GitHub is. If this is the case, we are welcoming you to go through our article and find everything about it and why it is so popular and used all around the world.

What exactly is GitHub?

If we want to go all technical and just point the obvious we could say that GitHub is basically a WEB site and cloud service used for storing and managing code in all languages. But to truly understand why you should use GitHub and not Dropbox or any storage service instead you need to understand concepts like Version Control and Git.

Version Control

Version control is meant to help developers to work separately on different parts of codes and update is separately not breaking the original one. Take note that this option is meant when there is a big project and has more than one coder working on it. If you are a solo coder on your personal project this might not be anything groundbreaking for you personally. But let’s now assume that you are part of a team and that your task is to edit only one function of a project and other people working will also have their tasks. With version control, you could take only part of the code and work on it and once you are finished merge it back into the main repository. All changes in the main code are automatically tracked and can be easily reverted back if needed. The good stuff is that rolling back can be used only let’s say on a code you submitted and other changes made to the source can be kept. As you can see this makes a very good and efficient working space and a good coding environment.

Git

Git itself is a specific version control system, an open-source version control system to be more precise created by Linus Torvalds in 2005. It is a distributed version control system, which means that the entire codebase and history is available on every developer’s computer, which allows for easy branching and merging. Currently, over 87% of worldwide developers are using Git on a daily basis.

So GitHub is?

GitHub is a profit company that offers a cloud-based Git repository hosting service, in other words, it automates and makes it easy for everyone to use Git for version control and collaboration. It focuses on user interface and ease of use so even beginner coders can use it right away without any large confusion and using command lines and setting it themselves manually. GitHub also has a free personal plan in which you can host a public code repository completely free. This option placed GitHub very popular with open source projects. If you are a company you can purchase a plan to have a private code repository shared only to members of your team or company.

Conclusion

As stated almost every developer on a planet uses some version of Git, many of them are on GitHub and there is a lot of open source projects on it. Some employers even ask to see your GitHub repository when deciding if they want to employ you, think of it as a portfolio for coders. There is not a single disadvantage and not a single argument against using it, especially it has a personal free option. So if you want to look better and more professional in the coding world go, make an account and place some code on it, share it with the world, and see how it goes. You might even get some help on projects from other coders if you need it.

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.

Hello everyone, in today's tips and tricks we will focus on providing you with various solutions on how to solve the Device not migrated error that appears after the Windows update has been performed. Sometimes sadly updates to our operating systems can introduce us to various issues that look scary but in reality, they are solvable and not so scary at all. After all who would not find this message concerning, especially when it happens in the middle of work. The first thing that would pop into my mind is that I have lost tons of work and that something in my hardware has gone very wrong and it is dead. Luckily that is not the case and this error means that due to Windows update drivers were not properly transferred due to some compatibility issues, maybe it was a corrupt update file, etc. Of course, the reason could be hardware malfunction as well, but if everything was working fine before the update, it is a software issue, and I must say it is a common one and fixable. Please keep reading this guide in order to fix the Device not migrated error.

1. Update the Driver

   You should always try this first, if the device is not recognizable, try updating its driver and see if the problem vanishes. In order to update the driver, we will need first to locate which device has not been migrated properly, we will do this with help of a search engine on the internet like google for example. So open your browser of choice, go to a search engine (google for example) and type in the search box first line from your error message, yes, that scary one. You will be given which device has malfunctioned and was not migrated properly, now we will locate the device and update its drivers. To do this press WINDOWS + X on your keyboard to bring up Windows secret menu and choose device manager. Find device inside device manager, right-click on it, and choose properties. Go to the events tab and make sure that the device has migration issues. You have now 3 options for updating the driver, you can do it manually, automatically, or with the driver installer. We will cover all 3 options so you choose which one best suits you. OPTION 1: Manually. Close the Properties tab, go to the device manufacturer website and download the latest driver, if there are no drivers there, the only executable installer for the device skip this step and try the other 2. After you have downloaded the driver package from the website, right-click on the device and choose update driver. Now navigate to the folder where you have downloaded your driver package and update the driver. Reboot your system. OPTION 2: Automatic update. Close the Properties tab, right-click on the device and choose to uninstall. Once the device is uninstalled, restart your system, and Windows will automatically search and install the latest driver for the device. OPTION 3: Via driver installer. If you have downloaded .EXE or executable driver installer from device manufacturers web site try installing it, if the installation fails, try using compatibility mode for the installer. Navigate where the installer is located, right-click on it, and choose properties. Go to compatibility TAB and try installing it with administrator privileges in Windows 8 mode. Reboot your system after this step. This should solve the issues, however, if the issue still persists, follow the next steps.

2. Verify the Corrupted System Files

   Press WINDOWS + X on the keyboard to open the hidden system menu and choose Command prompt (administrator) In the command prompt type in: sfc /scannow and press ENTER. The scanning process and repair of files will take around 15 min. Leave it to finish completely, do not restart, work on the computer or shut it down while the process is active, and only after it is finished reboot your system.

3. Update Windows.

   If your Windows is not updated sometimes this issue can be resolved by updating it on the latest version. Click on start and then on settings. Once the settings screen is opened, find and click on Update and Security. Go to the Windows update tab and click on DOWNLOAD or click on check for updates for the latest Windows fix.

4. Reset BIOS to factory settings.

   Sometimes BIOS not being properly configured can cause issues in Windows itself and prevent it from detecting PnP devices thus creating this error. Restoring BIOS back to the factory setting can help. Turn off your computer and turn it back on. Press delete, f12, f11, or any other key which will take you to BIOS (default key is delete but sometimes manufacturers map this to another one. Once your screen turns ON you will see in the bottom message which key needs to be pressed in order to enter BIOS). Sadly since every BIOS could be different we can not cover step by step guide for each but you need to find the option where you load BIOS defaults, click on it save, and exit. Your computer will restart and boot into Windows, check to see if the problem still persists.

5. Update BIOS

   BIOS can cause issues with certain PnP devices when the newest Windows update is rolled. If reverting BIOS to the factory setting has not been successful try update. Go to your motherboard manufacturer website, find the update and read step by step guide there since updating BIOS differs from version to version and from manufacturer to manufacturer. After the update is done, restart the computer and hopefully, the error is gone.

6. Perform a System Restore

   If everything else fails, perform a system restore to get Windows back into the state before the update was installed and when everything was working fine. Press WINDOWS + R on the keyboard to open the run dialog. In the run dialog, type control panel and press enter to enter control panel, locate recovery and click on it. Inside the recovery screen click on Open System Restore. Choose a date when everything was working in order, the best bet is the date before Windows update and roll it back. Click on date, and then on next.

If VirtualBox suddenly displays a black screen without any text or mouse cursor when you are trying to boot a guest operating system, then read on as this post will guide you in fixing such an issue. This black screen occurs when Windows 10 failed to provide a specific setting that VirtualBox requires. Consequently, you will not be able to install or use any guest operating system in VirtualBox even if your PC has virtualization support, the best thing you can do now is to fix this black screen issue. There are two ways you can fix this black screen in VirtualBox, you can either try to disable Hyber-V or disable 3D Acceleration. For more details, refer to each one of the given options below.

Option 1 – Try to disable Hyper-V

Hyper-V is a built-in virtualization tool available in Windows that helps users in creating a virtual machine as well as install a guest operating system without using any third-party tool like VMware, VirtualBox, and many more. However, the problem with this virtualization tool is that some systems cannot run it and VirtualBox simultaneously which is most likely why the screen abruptly turns into black. Thus, you have to disable Hyper-V to resolve the problem. How? Refer to these steps:

• In the Start Search, type “Turn Windows features on or off” and then click on it from the results.
• Once you’ve opened the Windows Features window, remove the checkmark from the Hyper-V box.
• Click the OK button and then restart your computer.
• Now try to use VirtualBox again and see if the problem is fixed.

Option 2 – Try to disable 3D Acceleration

The guest operating system will use the host computer’s GPU to render 3D graphics if you enable the 3D Acceleration for the virtual machine. To simply put it, it will enhance the graphics of the virtual machine and will let you use 3D graphics. Although it may seem nice, it can actually cause the black screen to appear as well so you might have to disable it to isolate the problem. In fact, a lot of operating systems have failed to use the 3D Acceleration for the guest operating system because of this black screen issue. To disable it, follow these steps:

• Open VirtualBox on your computer and select the virtual machine.
• Next, click on the Settings button and go to the Display section.
• After that, look for a checkbox named “Enable 3D Acceleration” located on your right-hand side and then uncheck it.
• Save the changes you’ve made and reboot your PC and see if you can now run the virtual machine without any problem.

Sticky Notes is one of the useful programs and in the early days, the option is available for users to change the font size of the text a lot easier. However, for some unknown reason, Microsoft decided to get rid of this feature in the latest Windows Update. One would expect that the feature will be replaced by an even more useful feature but it’s not which makes the Sticky Notes app worse than before. Worry not though for it doesn’t have to stay that way as there is another thing you can try to change the font size in your Sticky Notes app and that’s what we’re going to cover in this post. As mentioned, Microsoft removing this font feature is quite strange and in the past, users asked for this feature and since it’s no longer available, you can try following the steps given below to bring it back. And for that, you need to go to the Ease of Access section in the Settings app. Refer to the steps given below for more instructions. Step 1: First, tap the Win + I keys to open Settings and then go to the Ease of Access section. Step 2: After going to the Ease of Access menu and select Display from the list of options. Step 3: From there, you should see an option that says “Make text bigger”. And then use your mouse to navigate to the slider to change the size of the font. Note: Take note that after doing all the steps above, it will change not just the Sticky Notes app but also everything in Windows 10. This method is actually the best since it only changes the size of the apps rather than a wholesale change in your Windows 10 computer. Step 4: Next, scroll under Display until you see the “Change the size of apps and text on the main display” option where you’ll see that the option is 100% but you’ll want to change that to 125%. Step 5: After that, click on the drop-down menu and select 125% and then restart your Windows 10 computer. Step 6: Now open the Sticky Notes app and check if you can now change the font size in the Sticky Notes app.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the reason why the calculator app is not working properly. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism (.)exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Option 4 – Try to reset or reinstall the Calculator app

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:

• Click on the Start button and go to Settings > Apps > Apps and features.
• Next, look for the Calculator app from the app list and click on it to see its other options.
• After that, select the Advanced options and go to the Reset section and then click on the Reset button to reset the Calculator app.

Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

The new widget's menu inside Windows 11 is generally met with a positive attitude but there are still users which prefer not to have it. Luckily for them, Microsoft included a very easy way to turn the widgets menu on or off. Follow this easy guide to see how. Right-click on the widget button in the taskbar and click on Hide from Taskbar and that’s it Alternatively, you can also turn it off via the setting app. Go to the settings app and navigate to Personalization > Taskbar > Taskbar Items and flipping the switch beside Widgets to Off. Please note that both methods will only hide the button to toggle widgets menu, at the current state there is no really a way to actually turn it off, only hide it and make it not available to bring it up.
