If you are using a multi-monitor, then you might find it quite useful. It helps many users with their work and brings more productivity. And over the past few years, Windows has managed to offer one of the excellent multi-monitor features where users can plug in an additional monitor and access their work or use their computer seamlessly on both displays. This is really handy, especially for users who are graphic designers, gamers, and other professionals who have to use a larger screen for their work. One of the biggest inconveniences for users who use multi-monitor is that the Taskbar is switched on, on both displays, by default. This default arrangement is most likely to cause clutter on the second display. So if you are one of these users who find such a thing annoying, then you will find this post useful for you as we will walk you through how you can move the Taskbar to a second monitor. To get started, follow the instructions laid out below. Step 1: The first thing you have to do is right-click on the Taskbar. Step 2: Next, uncheck the “Lock the taskbar” option. Step 3: After that, click and hold the taskbar and drag it to the second monitor. Step 4: Once done, click the mouse button on the place where you want to place the taskbar. Step 5: Now right-click on the “Lock the taskbar” option to lock the taskbar. Once you’re done carrying out the steps given above, there are Advanced Options you can explore. This array of advanced options are offered by Windows 10 to fine-tune the multi-monitor experience of users. For instance, you have the option to choose to show the taskbar on an active screen only or combine the buttons on other taskbars. It would be better if you try out different variations and stick with the best one. In addition, you could also move the taskbar from one display to another.

You might be trying to play music files using the Windows Media Player, but were unable to do so since you encountered an error saying, “Windows Media Player Error – Server Execution Failed” error. If you encountered this error, worry not for this post will guide you on how to fix it using some potential fixes. In the error message, the “Server execution failed” indicates that the “wmplayer.exe” is still running or shutting down at that point and it is possible that it is stuck which is not able to close properly. To fix this error, there are several potential fixes you can try. The first one is to run the Video Playback troubleshooter.

What is Regsvr32 Error? - What Is It?

Regsvr32 is basically a command-line utility.

This command is used to register and unregister OLE controls for example the digital link library files and ActiveX controls in the Windows Registry. This command appears as the Regsvr32.exe file and is installed in the Microsoft Windows system file in the %systemroot%System32 folder.

The Regsvr32 command loads the library and tries to call the DllRegister Server and DllUnregister Server. In other words, it helps to register COM-based digital link library files to run different programs on your PC.

However, when the Regsvr32.exe file gets corrupt, you get the Regsvr32 to troubleshoot the error message on your computer screen. It can be displayed in various ways including the following:

“To register a module, you must provide a binary name.”

Error Causes

Generally, Regsvr32.exe becomes corrupt because either the load library, DllRegister Server or DllUnregister Server function fails. This indicates that the dll specified path was missing, incorrect, or couldn’t be found.

Here’s how the error messages are often displayed while registering a dll using Regsvr32.exe:

• “The command-flag "%1" is not valid. Please review the command usage and try again.”

If this error message is displayed, it typically means that you entered an invalid combination of command-line arguments or switches when calling upon the Regsvr32.exe application.

• “To register a module, you must provide a binary name.”

The cause of this error message is that you called the Regsvr32.exe function with no modules to register located in the command line arguments.

• “The module "%1" failed to load.nn Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.nn%2.”

This Regsvr32 error message indicates that Windows had problems with loading the modules that you have identified in the command line.

Further Information and Manual Repair

Here are 2 recommended solutions to fix the Regsvr32 error on your PC:

1. Re-run the command

   You must re-run the Regsvr32 command from an elevated command prompt. For this, go to the start menu and type Command Prompt in the search box.

   Now right-click the Command Prompt and click the option that says Run as Administrator to run the command on your PC. If it prompts you to enter an administrator password, type the password and then click Allow to run the command.

2. Register a 32-bit Dll using a 32-bit version of Regsvr32 on a 64-bit version of Windows

   This may sound tricky but it is even simpler than the first solution discussed above. To register a 32-bit DLL using a 32-bit version of Regsvr32 on a 64-bit version of Windows, open an elevated command prompt.

   After it’s opened, if you see the 32-bit DLL is located in the following path: %systemroot%System32 folder, move it to %systemroot%SysWoW64 folder. Once you change paths, run this command: %systemroot%SysWoW64regsvr32 <full path of the DLL>

Try following these 2 recommended solutions to immediately fix and repair this error on your computer.

The solutions should eliminate the occurrence of error messages such as “To register a module, you must provide a binary name.” It is so easy and effective and you can do it on your own without calling over a professional.

Windows 11 has come a long way from its infant stage. Today it is incredibly good and stable operating system that also looks good and modern. Unfortunately, fancy animations and good graphics come with a price, in this case, slower performance on some little older and weaker computers.

Animations itself which include also fading effects can sometimes feel slugging and laggy and have a general overall feeling of delay. For a more old-school instant experience, you can turn off animations.

In order to turn animations inside Windows 11 follow this simple guide:

First thing is to open Settings by pressing Windows + i key combination or you could open Start and in the search box type in Settings and then click on its icon.

Once inside settings on the left side find Accessibility and click on it to select it. Once it is selected on the right side choose Visual effects. Inside the visual effects section click on the switch next to Animation effects to OFF. You can also turn off transparency effects in this section if you wish if you have an older GPU in order to speed it up a little.

That is all you need to do, settings will be automatically saved and all animations will be turned off for a quicker and more responsive feeling when working inside W11

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.

Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!

How to speed up Windows 11?

1. Disable startup programs

There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.

To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.

This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.

2. Expand your memory and storage

If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.

Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.

In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.

3. Clean up disk space

If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now. 

Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).

A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice. 

For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.

Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.

4. Install pending updates

This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.

5. Disable visual effects

As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.

To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.

Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.

In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.

6. Get rid of bloatware

Bloatware is one of the biggest culprits of slow computer speed. 

Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.

To boost your Windows 11 computer, go to Settings > Apps > Installed apps. You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’. 

Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.

Summary

These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!

If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
2. An issue with system maintenance could cause the problem.
3. Malware or some other software might have created an undetectable hidden file.
4. Space could be occupied by the trashbin folder.
5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
6. Run ChkDsk
7. Clear all Junk files
8. Reduce the space occupied by the system restore points
9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:

• In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
• Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
• After that, click on the System Maintenance troubleshooter to run it.
• Once the process is completed, restart your computer.

Reddit is one of the most popular websites in the world and how Microsoft is opening doors to everyone in its new store Reddit took a logical step and made a Progressive web application and placed it in it. Being a Progressive web app makes it more familiar and feels like a home experience using it for a lot of Reddit users. Reddit itself has a large community and active topics discussions all the time about anything. Bringing it to Windows as an application is, in my opinion, a great move since as an application it is independent, more light-weighted, and offering some other advantages specifically tied to being a standalone windows application. Everyone familiar with and using the Reddit website will feel right at home in this app and you can start using it right away.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.
