Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

About Potentially Unwanted Applications

What is a Potentially Unwanted Program (PUP)?

Have you ever detected an unwanted program on your computer system and pondered how it got there since you’re confident that you didn’t consciously download or never gave authorization to be installed? Potentially Unwanted Programs (PUP), also known as Potentially Unwanted Applications (PUA), are programs that you never wanted in the first place and sometimes come bundled with freeware software. Once installed, the majority of these applications can be hard to eliminate and become much more of a nuisance rather than a benefit. The term PUP was coined to outline this crapware as something other than malicious software. Similar to malicious software, PUPs cause problems when downloaded and placed on your PC, but what makes a PUP different is you grant consent to download it – the fact is very different – the software installation bundle actually tricks you into accepting the installation. No matter whether it is viewed as malware or otherwise, PUPs are nearly always harmful to a computer owner as they will bring on spyware, adware, keystroke logging, along with other nasty “crapware” features on the PC.

What do PUPs do on your PC, precisely?

PUPs come in many forms. Commonly, they will be seen in adware bundlers which are known to use aggressive and misleading advertising. Most bundlers install multiple adware applications from various vendors, each of which has its own EULA policy. Safebytes Anti-Malware totally eliminates this threat and safeguards the computer against unwanted programs or adware infection. They will also come in the form of web browser extension add-ons and toolbars. They may keep track of your online movements, redirect your search results to risky sites where spyware and adware can be downloaded, hijack your search page, and slow your web-browser down to a crawl. PUPs lie in the gray part of the software spectrum. Also in the large majority of the cases, people won’t be aware that they are installing an unwanted program. Even if the PUPs really aren’t inherently malicious, these software programs still do practically nothing good on your computer system – they will take valuable resources, slow your PC, weaken your computer security, making your PC more vulnerable to viruses.

How you can stop PUPs

• Read carefully before accepting the license agreement as it might have a clause about PUPs. • Do not accept standard, express, default, or any other installation settings which are recommended. Always select “custom” installation. • Install an advert blocker/pop-up blocker; Deploy anti-malware products like Safebytes Anti-Malware. These types of software programs could establish a wall between the computer and online criminals. • Be alert if you download and install freeware, open-source software, or shareware. Never install applications that seem suspicious or malicious. • Use official product websites for downloading software. Stay away from download portals altogether as most websites compel users to download the software using their own download manager, which is often bundled with some sort of unwanted programs.

Can't Install Safebytes Anti-malware due to the presence of Malware? Do This!

Error Causes

Some of the most common causes for internal error 2503 are:

• Permission not granted to access the Windows Installer Folder
• Viruses
• Problems with Windows Installer

Further Information and Manual Repair

To repair this issue on your PC without any professional assistance, try the DIY methods given below:

Method 1

Internal error 2503 may occur when your account has limited privileges. You don’t have the privilege to use or access the Windows Installer folder. Your inability to access this folder hampers you from successfully install or uninstall the desired program on your PC. To gain access, you need to ensure you have permission.

• For this navigate to the C:\windows folder. Here find the installer folder and then right-click and choose properties.
• After that click on the security tab and check if the System and Administrator account has Full access permission.
• For that make sure the system group option has ‘all’ selected to allow you full permission.

• Follow the same steps and now type ‘msiexec /regserver’ in the box and then press enter. This will resolve the issue.

Method 3 - Remove Viruses

If internal error 2503 is triggered by a viral infection on your PC, then it is advisable to download an antivirus and scan your entire system. Viruses are notorious for system failures and pose data security threats. If not removed timely, these malicious programs can damage your PC. To remove all viruses on your system, run an antivirus. An antivirus detects all malicious software programs including viruses, malware, adware, and spyware. Delete all the malicious files found right away. This will help resolve internal error 2503.

The win32kfull.sys file is one of the kernel-mode device drivers in your Windows 10 operating system. In case you don’t know, there are two kinds of device drivers – the first ones are the normal drivers that communicate between your hardware and the operating system while the second ones are the kernel-mode drivers. The latter is necessary for booting your OS. And there are times when you encounter the win32kfull.sys error while booting your PC. Here’s the full context of the win32kfull.sys error:

“SYSTEM_SERVICE_EXCEPTION (win32kbase.sys) APC_INDEX_MIXMATCH PAGE_FAULT_IN_NONPAGED_AREA”

This error could be caused by corrupted or outdated drivers with incomplete files or it could be caused by some driver or software installed on your computer. To fix this error, here are some troubleshooting options you need to check out.

Option 1 – Try updating all the Drivers

As pointed out, the win32kfull.sys error can be due to outdated or corrupted drivers that are not compatible with your hardware. These drivers include but are not limited to display, network, sound, hard drive, and more. If you are not able to access the internet, you can just manually download the update using another PC. To update your drivers, here’s what you need to do:

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.

Option 2 – Identify and uninstall problematic programs by putting your PC in a Clean Boot State

One of the main causes of BSOD errors like win32kfull.sys is a problematic program that could clash with your existing operating system as well as computer architecture. There are tons of programs that are either incompatible or conflict with the existing drivers or software in your system. To identify such programs, you need to put your PC in a Clean Boot state. How? Follow these steps:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Once you have identified the program causing the problem, uninstall it right away from your Control Panel.

Option 3 – Perform an SFC scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the win32kfull.sys error. 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. 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.

Error code 0xc000021a - What is it?

Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c. 

Solution

Error Causes

There are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:

• Computer malware has infiltrated your device.

• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.

• When there are mismatched system files installed or system upgrading process failed or still incomplete.

• Premature unloading of Wbemprox.dll

• Newly installed third-party software is not compatible with the operating system.

• There are corrupted, outdated, or incorrectly configured device drivers.

• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.

• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.

Further Information and Manual Repair

In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes.

If you choose the Remove files and clean the drive option, the procedure will take longer as it will erase all the files permanently. In this case, deleted files cannot be recovered. However, if you don’t want to remove files permanently, select Just remove my files. 4. Once you’ve decided how to reset your system, click on Next once the Warning screen appears. Afterward, choose Reset once prompted. When the process completed, click on Continue.

Method Four: Download an Automated Tool

Can’t seem to put up with the long and technical manual repair process? You can still fix this error by downloading and installing a powerful automated tool that will surely get the job done in a jiffy!

The number of Hertz is the number of how many images your screen draws in one second. So monitor with a refresh rate of 60Hz will draw 60 images each second on your screen. To most users, this will look fine and enough but actually, if you would place them in front of a 120Hz screen difference will be visible right away.

Benefits of higher refresh rates

In most simple words just looking at a screen that has a higher refresh rate will produce a more natural feel of things, although some people would argue that flickering can not be seen on 60Hz monitors and that should be enough, I would argue that they never watched the movie, played the game or used high refresh rate screen when they can state something like that.

Yes, 60Hz might be enough to look at the web page or read some documents but long exposure to 60Hz can have a tiring effect on the eyes in the long run. 120Hz and above just feel more relaxed and it is far less demanding on the eyes. Watching movies also is much better on a higher refresh screen, with way much less motion blur in fast scenes giving the overall experience a greater natural feel.

Gaming is perhaps an area where a refresh rate of 120Hz and above will show its best. Having a higher refresh rate will be easier on your eyes and can even give you a competitive edge. When for example you have twice more images per second on your screen than your opponent his movement will be more fluid and predictable because of that and overall precision will be much higher when moving the cursor in the game since more frames per second means more precision and smoother movement.

The dark side of high refresh rates

After all the positive things that were said about the advantages of high refresh rates, it is just fair to look at some negatives or in this case only negative one and that is Computer power. As said in the previous section having a 120Hz refresh rate means having 120 frames displayed on the screen per single second. Having even higher monitors like 360Hz means even more frames per second and in order to actually see all of that frames you will need to have enough computer power to back it up. Having for example screen with a refresh rate of 240Hz means nothing if your GPU and rest of the computer are able only to push 150 frames per second, in this case, you will still have 150 frames in one second despite the monitor being able to go to 240.

Conclusion

Generally and with all of my heart I would recommend moving away from 60Hz monitors, yes they are cheaper and more affordable but at the end of the day if you are someone like me who spends most of his daily time in front of the computer you would be grateful to have higher refresh rate screen and save your eyes, and after all, why not enjoy some smoother and better movie and game experience as well as saving your eyesight.

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.

• 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.
