8 Android Apps that threaten your security

If you are trying to connect to the internet using a Wi-Fi, Ethernet, or a Wi-Fi connection and you suddenly encounter Error 633, then read on as this post will guide you on how you can fix this problem in your Windows 10 computer. According to users who encountered the same problem, when they try to connect to the internet, an error pops up that states, “The modem or other connecting device is either already in use or not appropriately configured”. This error is the VPN Error 633 which indicates that the modem is malfunctioning due to some broken configuration. It is possible that this broken configuration is caused by the WAN Miniport device which is associated with your preferred VPN protocol. It could also be due to the TCP port that’s required for the VPN connection to work might be used by another application. There are instances when Error 622 could occur when there are multiple internet connections set up on one device or when the communication port is exploited by another program. It could also occur when the affected modem is not bound to one specific device. Thus, any model and computer can be affected by this problem. The first and basic thing you can do to fix the VPN Error 633 is to turn off or unplug the modem your computer is using and then plug it back in to see if the problem is fixed. If not, then there are several other potential fixes you need to check out to resolve the problem. You can try the suggestions provided below and see if any of them help.

Option 1 – Run the Network Adapter Troubleshooter

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 2 – Try to explicitly reserve the TCP port

The next thing you can do to fix the error is to reserve the TCP port explicitly and to do that, follow the steps below.

• Tap the Win + R keys to pull up the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters
• After that, follow the path New > Multi-String Value on the edit menu and rename the multi-string value as “ReservedPorts” and then double click on it.
• Now in the value data of ReservedPorts, input “1723-1723” and click OK to save the changes made.
• Close the Registry Editor and restart your PC. Once your computer has restarted, check if the VPN Error 633 is fixed or not.

Option 3 – Try to use the netstat command

• In the Windows Start Search, type “cmd” and from the search results that appear, right-click on Command Prompt and then select the “Run as administrator” option.
• After opening Command Prompt as admin, type this command and hit Enter: netstat –aon
• After that, the output will be displayed and from there, look for the process ID or PID of any program that uses the TCP port 1723 on your computer.
• Next, type this next command and hit Enter: taskkill /PID PID /F
• Once the command has been executed, the concerned program will be forced to close and the TCP port 1723 will be freed up. Keep in mind that the taskkill command ends the process corresponds to the process ID number and the given command above, “/F” option is used to end the program’s process forcefully.
• Now restart your computer and after that, the concerned program should start using a TCP port other than 1723 which leaves the TCP port 1723 free for your internet device to use.

Option 4 – Remove any irrelevant internet device programs

You could also try removing any irrelevant device programs since it is possible that any of these programs could be the one that’s causing the modem to malfunction. These irrelevant programs could be an internet booster or third-party tools that comes with the modem and so on. These programs are not necessarily needed for your modem to function. Thus, if you want to fix the VPN Error 633, you can try uninstalling them and see if it fixed the error.

Option 5 – Update the Network Adapter drivers

You might also want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the VPN Error 633, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly. To reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

We have all experienced Windows errors over time and that can range from simple ones that will do very little to no harm and can be even system breaking making us lose our work or completely making the PC unusable. No one likes them but they happen, and usually, they happen once we least expect them.

No matter how frequent and unpleasant they might be there are ways to keep them at the minimum and even avoid them.

We will discuss steps that you can take in order to do this, simple tips and guides on how to keep your computer in top form and eliminate not just Windows, but any kind of errors altogether.

Keep your hardware clean

Believe it or not, some serious Windows errors like the dreaded blue screen of death can come from hardware issues not from the software at all. It is very important to keep your computer clean and with enough air flow so it can function properly.

Not so far ago we had an article about cleaning your hardware detailing what and how to do it. Here is a link to the article: https://errortools.com/windows/cleaning-your-pc/

Do not keep applications you are not using

Keeping applications on the drive might seem harmless but sadly that is not the case. Some applications have a certain impact on the system itself after all most of them are tweaking registry entries in Windows and sometimes having too many applications means an increased possibility of conflict over certain resources even when they are not running.

Some applications like adobe creative suite, for example, will have certain services always running in the background, and more of these kinds of applications you have, more services, more places for unexpected errors when they collide. Some of them will also install certain dependencies that could be problematic.

The general idea is: if you are not using it, uninstall it and you will be safer and more resilient to errors inside OS.

Do not use pirated or cracked software

Besides moral and law implications that using pirated or cracked software might bring you there are also certain other things that might be problematic. Certain "free" software might come packet with some problematic malware, for example, it is not uncommon for attackers to use some popular software to pack their malicious application with it.

Other things might be wrong and incomplete tweaking with application in order to bypass security and thus bringing some instability due to scripts needed to run in order to achieve this goal.

Keep your drivers updated

Errors can also come from old drivers or bad drivers, device manufacturers are not all-knowing and perfect, and sometimes drivers can wreak havoc on the system. Having updated drivers can minimize any kind of unexpected behaviors inside the operating system making it more stable and reliable.

You can check your driver version in the control panel inside the Windows OS and then compare it to the ones found on the manufacturer's site, if there are newer available it is recommended to download and install them,

Keep software updated

Applications can have bugs, and bugs can lead to certain errors both in the system and when using the app as well. It is in your best interest to get the latest patch or newer version of the software in order to avoid these unpleasant experiences.

Also, certain codecs and extensions that are installed directly in Windows can also have some unpredictable behavior, updating is the best solution to keep them in line.

Keep Windows updated

Same as with drivers and applications, Windows itself is not immune from bugs and some unpredictable issues. Luckily Microsoft is always working on fixes and features of Windows but in order to actually have benefited from that work, you will need to keep Windows updated. Sometimes a bad update can introduce some errors but you can always roll back to the previous and wait for them to fix everything and then download them all.

Check the health of your hardware regularly

Hardware components have their life cycle, more quality ones tend to last longer but eventually, they will reach the end of their lifecycle. There are a lot of testers for various components in your computer that can check different things and provide you with information about the state of your components.

If you are on Windows 11, Microsoft has included a basic health app inside OS, just type PC health check in search and start the app. For some more detailed information and advanced checks, you will have to use a custom application. There are plenty of them specialized for single components like RAM, SSD, etc. A simple google search with providing you with top results and most of them are free for personal use.

Remember, a faulty component or component that is reaching its life cycle can produce many errors inside the operating system.

You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

• First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
• Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
• After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.

Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
• From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
  • “This policy setting disables the acrylic blur effect on the logon background image.”
  • “If you enable this policy, the logon background image shows without blur.”

• Now click on OK and then check the login screen.

Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

Recently, a number of users reported an error in Google Chrome that says, “ERR_SOCKET_NOT_CONNECTED”. If you are one of these users, read on as this post will guide you in resolving this error.

So you have just got home from that new computer store with your fancy and all-new mouse, screen, keyboard, etc. You plugged in your new component, Windows detected it, installed drivers for it and it is working like a charm. A few months later down the road and the computer starts little by little to slow down. Plug and play is a great concept, and automatic detection is even greater but how time passes old unused stuff piles in your hard drive and in Windows itself thus slowing down your computer and taxing it more and more as new components and software are added. Old drivers from old components sadly are not removed from Windows itself and over some larger period of time they can pile up and slow down your daily operations on the computer or even cause some problems in it. This guide will teach you how to manually remove old unused device drivers from your Windows so it is fresh and like new again.

Making old devices visible

In order for us to remove old drivers, the first thing we must do is make them visible in our device manager, old drivers are hidden and will not show up, we must make this happen. We do this by pressing WINDOWS + X keys on your keyboard to bring up a hidden menu in Windows. Once the menu appears, click on Command Prompt (admin) Once the command prompt with administrator privileges comes on-screen type in it following string: The device manager will open, go to view > snow hidden devices in order to show unused devices.

Removing old device

Open any category and if there is a device that was once used and still has its drivers in the system it will be shown as faded out. Right-click on the device and click on uninstall device to remove it completely from your system. Please always be careful when removing devices so you do not remove the device which is being used by mistake and always double-check that you are removing something that you used to have on your system. This method will show all hidden devices even ones that are hidden but crucial to the system working properly.

In this post, we will discuss what the “ bootres.dll ” file is in the Windows 10 operating system and where it’s also located. In addition, you will also be guided on how you can replace or fix a corrupt bootres.dll file which may prevent you from booting to your Windows desktop and will display an error message instead saying, “Boot critical file resourcescustombootres.dll is corrupt”. There are times when this error might also boot your PC to the Automatic Repair screen. DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files so if there is a need for the code, the related file being called by a certain application is loaded into memory and used. If the software or the operating system is unable to find the concerned DLL file or if the DLL file ends up getting corrupted, you will most likely get an error message. In case you don’t know, the bootres.dll file is a critical system OS file, size 90KB, and can be found in the Windows folder. It is a part of the Boot Resource Library and portrays an important role in making sure that your PC boots properly. So if it ends up getting corrupted, your PC may fail to boot correctly and you’ll get an error message instead. To resolve this problem, here are some suggestions that might help. If your PC automatically boots to the Automatic Repair screen, you need to click on that option to run the Automatic Repair. If it doesn’t work, you have to boot into the Advanced Startup options to manually access and run the Automatic Repair. Once you’re in the Advanced Options, you will be able to:

• Run Automatic Repair
• Use System Restore
• Start Windows from an external device
• Access Command Prompt
• And use the System Image Recovery to restore Windows from a Factory image.

If the Automatic Repair fails to fix the problem, you may have to use System Restore or the Command Prompt to carry out further troubleshooting steps. Refer to the guide below to use these tools.

Option 1 – Try running the System File Checker in Safe Mode

Running the System File Checker is the safest way to fix DLL file missing or corrupted errors are thrown up by the Windows operating system as it could give you better results. 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 with good system files that might be causing the Machine Check Exception BSOD error. To run the SFC command, follow the steps given below.

• Boot your PC into Safe Mode.
• 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.

Option 2 – Try running the DISM tool to repair the System Image

To repair the System Image, you need to use the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: Dism /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.

Note: The command you executed will check for Windows component store corruption and will restore its good health. The scan might take up to 15 minutes. Once it is done, you have to restart your computer.

Option 3 – Try to repair the MBR and rebuild BCD

To repair the MBR and rebuild BCD, follow these steps: The problem might boil down to the Master Boot Records since the previous case has already been isolated. There are times when the Master Boot Records can get corrupted and even though it is a serious issue, it can still be rectified by repairing the Master Boot Record.

• Tao the F8 key while booting the system to go into the Windows Recovery Menu.
• Next, click on Troubleshoot.
• Then click on the Advanced options to get into the Automatic Repair menu.
• After that, you have to use the bootrex.exe tool, so click on the command prompt and type in the following commands, one after the other:
• bootrec /RebuildBcd
• bootrec /fixMbr
• bootrec /fixboot
• Exit and then go ahead and restart your PC.

Option 4 – Try running the ChkDsk utility

One of the best options you must try is running chkdsk as it will check the disk for any errors and repair them automatically. To use it, follow these steps:

• Boot your PC to the Advanced Options menu and click on Command Prompt.
• Once you’ve opened an elevated Command Prompt, type in the following command and tap Enter to execute it:

chkdsk C: /f /x /r

Note: “C” is the drive root drive so it could be changed if you’re using a different one.

Option 5 – Try resetting your PC

Go to the Advanced Options > Troubleshoot > and select the Reset This PC option from the menu and then select Keep my files.

Microsoft has started to use group along with every open window in the Taskbar ever since the release of Windows 10. Early on, they used to show an individual entry for each one of the windows after grouping them which makes the taskbar look cleaner and organized. However, the main issue lies in the fact that you have to hover on your desired window to get on to them. At the time of writing, you need to tap the Ctrl key and click on the taskbar icon to open the last active window but you have to only click on the program’s taskbar icon after you apply the tweak given in this post for the last active window to open. Take note that the “Last Active” windows feature will only work if the taskbar buttons are combined. Before you get started doing the instructions given below, you need to create a System Restore Point first since you will be dealing with registry files and modifying some of the critical settings in Windows 10. Once you’ve done this, proceed to the given steps below. Step 1: 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. Step 2: If a User Account Control or UAC prompt appears, just click on Yes to proceed to open the Registry Editor. Step 3: Next, navigate to the following registry path:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced

Step 4: From there, right-click on the right side of the panel and select New > DWORD (32-bit) and then name it “LastActiveClick”. Step 5: After that, double click on the newly created DWORd to modify its value. Put “1” as its value data. Step 6: Then click OK and close the Registry Editor. Step 7: Now restart your computer to successfully apply the changes made. Note: In case you want to revert back to the default configuration, all you have to do is set the value data of LastActiveClick to “0” or simply delete that DWORD and restart your computer to successfully apply the changes made.
