Mousepads are a common thing among computer users, everyone is using them and know what are they good for. Recently in the past few years, there are a lot of gaming mousepads on the rise, do you really need them, and do they back up their price? Short answer: YES, long answer: keep reading below.

Size advantage

One of the first things that one can see is the great difference in sizes between a regular mouse pad and a gaming one. Gaming pads have much more variety in size spawning all the way to really judge ones that you can use on your whole desk and place both keyboard and mouse on them. This will, of course, let you move your mouse more freely and have a much larger surface to use without the need to always lift the mouse up and center it on the regular pad.

Material advantage

Material on what are gaming pads built upon is extremely high in quality and usually even water phobic or water-resistant and it will allow great mouse movements on it. The backside is usually made of high-quality fabric that will stop slipping on the desk so the pad will stay at its pace during long sessions of work or gaming. Usually, standard mousepads are made with plastic or some other cheap material whereas gaming pads are made from fiber, high-quality fiber.

Other advantages

Among other great stuff that gaming pads have are wrist gel for hand resting and RBG light that looks cool, although RGB light is just a vanity that looks good gel for the wrist is a really good feature that will place less stress on your hands during long sessions of time spent in front of the computer.

Instaling and removing applications from your Windows can sometimes leave some traces that are unpleasant and can cause annoyances. One of these annoyances is the program in the startup section of the task manager.

If you ever opened task manager and went into the startup section trying to disable some of the startup items on your Windows boot there might be a chance that you have experienced and seen a program without any icon or information about it just sitting there.

This is due to some applications being removed from the system but for some reason, it still shows itself in startup and it is quite annoying. So here we will show you how to get rid of this annoyance so your startup is clean again without junk in it.

Removing a program from startup

Locating the source of the issue

The first thing of course is to open the task manager itself and navigate to the startup tab. Inside the startup tab right-click on the column header and tick or enable Startup type and command line. Now you will see the location of the supposed file (that is missing or you could just go there by right-clicking on the item, but here it is greyed).

99% of the time startup type will be registry since the file is missing, if it was a file fix would be just to simply delete the file in the folder but since it was installed and not properly removed registry key is still present but the file cannot be found. After confirmation that the file is indeed missing and that the startup type is registry open the registry editor by typing Regedit in search and pressing enter.

Removing the key from registry

Inside Registry editor navigate to: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. Inside on right part, you will see all auto-start entries added by installed applications.

Locate one that is causing issues by comparing its path with the path inside the task manager command line and delete the key. Once the key is deleted right-click on RUN on the left part and choose HKEY_LOCAL_MACHINE to quickly jump on that key location and repeat the process of key deletion if needed. HKEY_LOCAL_MACHINE will delete startup entry for all users and sometimes entry will not be present here since the application is not installed for all users or there are no other users on the machine.

After the procedure is finished, reboot your systems in order to apply changes.

The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• 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” check box 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” check box.
• 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 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.

Option 2 – Perform System Restore

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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.

 Restart your computer and see if the System32 folder still pops up at startup or not.

In any Windows operating system, Safe Mode is definitely a special environment used for troubleshooting issues as well as system diagnostics. Safe Mode allows you to remove any malware in your computer and troubleshoot issues that can’t be fixed when you’re in desktop mode. This is why Microsoft made sure that the Safe Mode option is not available directly and can only be accessed by pressing function keys such as F2, F8 (depends on what PC you are using) or via MSConfig. To make it easier for you to access Safe Mode, this post will guide you on how you can add Safe Mode to the Boot Menu options in Windows 10. As you know, Windows 10 now has Advanced Startup options that allow you to boot directly into Safe Mode without having to restart your PC and then tapping the special key a couple of times. However, if you really have to always use Safe Mode, it’s best to add it in the Boot Menu options. To do that, simply follow the steps below.

• Select Command Prompt (Admin) option from the WinX menu to open Command Prompt with administrator privileges.
• After opening Command Prompt, type the bcdedit /copy {current} /d "Safe Mode" command and hit Enter.
• Once the command is executed, you will see a message saying, “The entry was successfully copied to {74a93982-9486-11e8-99df-00270e0f0e59}”. This message indicates that Safe Mode was successfully added in the Boot menu option which means that you can now directly access it and boot your Windows 10 PC in that mode.

To check if Safe Mode was really added in the Boot menu options, you have to open Msconfig. From there, you will also have to use it to configure the boot settings for the Safe Mode entry. To do so, follow the given steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “MSConfig” in the field and click OK.
• Next, go to the Boot tab and find the Safe Mode option which should be located under the default Windows 10 mode.
• Afterward, you need to select the Sage boot option and Minimal. You also have to select the Make all boot settings permanent option.
• Make sure to increase the timeout to at least 10 seconds which will ensure that the menu does not disappear right away.

Note: In similar steps as above, you can add the Safe Mode with Networking and Safe Mode with Command Prompt entries as well. Just simply select “Network” for Safe Mode with Networking and “Alternate Shell” for Safe Mode with Command Prompt. Once you’re done adding any of them, click on Apply and restart your PC. In addition, if you wish to remove the entry, you just have to open MSConfig again and select the entry you want to remove, and then click Delete.

When your computer boots up or when it just woke up from sleep but it suddenly encounters a Blue Screen of Death error, saying, “HAL INITIALIZATION FAILED error with STOP CODE 0x0000005C”, then read on as this post will give you some fixes that might help in resolving the problem. You will see the following error message on your computer’s screen when this error pops up:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. If you’d like to know more, you can search online later for this error: HAL_INITIALIZATION_FAILED HAL INITIALIZATION FAILED 0x0000005C”

This kind of Blue Screen error indicates that there is a hardware or device driver problem in your PC. Aside from that, it also signifies that the initialization of the Hardware Abstraction Layer or HAL has failed. This happens only during the relatively short period that the Windows operating system is being initialized, specifically during phase 4 of Windows startup. What’s worse about this kind of Stop error is that it does not just go away after a computer reboot. You may have to boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options, follow the fixes prepared below.

Option 1 – Run CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you resolve the HAL INITIALIZATION FAILED error with STOP CODE 0x0000005C. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then restart your computer.

Option 2 – Run the DISM tool

If the first option didn’t work, then running the Deployment Imaging and Servicing Management tool can help you resolve the HAL INITIALIZATION FAILED error as it will repair the Windows System Image as well as the Windows Component Store in Windows 10.

• After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
• Next, 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.

Option 3 – Update the Device drivers

• Tap the Win + R keys to launch Run.
• Type in 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. Look for the device driver you and then select either “Update driver” or “Uninstall device”. 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.
• If you have chosen to uninstall the driver, follow the screen options to complete the process and then restart your PC.
• Connect the device and Scan for hardware changes – you can see this option under Device Manager > Action.

Option 4 – Try removing any external hardware

You might also want to remove any connected devices and external hardware in your computer as it might help in fixing the BSOD error.

Option 5 – Disable Fast Start-up

If you want your computer to boot faster, then you might have enabled Fast Start-up. This feature is ideal for computers that are using a hard disk drive. However, turning on this feature also means that when the computer boots, it might lag some drivers that are loaded when it initially boots up. Thus, it might be the potential cause of the UNEXPECTED STORE EXCEPTION BSOD error. Thus, you need to disable Fast Start-up. To do that, follow these steps:

• Boot your PC into Safe Mode.
• Then tap the Win + R keys to open the Run dialog box.
• Next, type in “control” to open Control Panel.
• After that, select Hardware and Sound and click on Power Options.
• Select “Choose what the power buttons do” from the left side menu pane and click on Change settings that are currently unavailable.
• Afterward, uncheck the “Turn on fast startup (Recommended)” entry and click on Save Changes.
• Now restart your PC for the changes to take effect and then check if the problem’s fixed afterward.

Option 6 – Disable your antivirus program

There are times when the antivirus program installed in your computer blocks file access and even disk access. Thus, disabling the antivirus program or any security software installed in your computer is always a good idea you can try when the Windows Update process does not go smoothly. So before you try updating your computer again, make sure to disable the antivirus or security program and once the Windows Update is done, don’t forget to enable the antivirus program back again.

Option 7 – Perform a Clean Boot

There are some instances that some conflicting programs installed in your computer might be the one that’s causing the HAL INITIALIZATION FAILED error. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

• 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” check box 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” check box.
• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Hello everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use. Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time. First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC When Task Manager opens, click on the startup tab on top. Once you click on startup you will get a list of applications that are set to be started when Windows is booted. You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them. Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.

KMODE_EXCEPTION_NOT_HANDLED – What is it?

Some users installing or upgrading to Windows 10 experienced the theKMODE_EXCEPTION_NOT_HANDLED Blue Screen of Death (or commonly known as BSOD) error. This error can be due to different types of things, ranging from software to driver issues. When you experience this BSOD error while trying to install Windows 10, it will prompt you to restart your computer every single time you experience it. In most cases, you will also not be able to proceed with the Windows 10 set-up.

Solution

Error Causes

The “KMODE_EXCEPTION_NOT_HANDLED” error is normally caused by:

• Hardware incompatibility
• A faulty device driver or system service

Further Information and Manual Repair

You won’t be able to successfully upgrade or set up Windows 10 if you continue to encounter this BSOD error. Note that this error will always prompt your computer to restart every time it happens, preventing you from completing the Windows 10 set-up.

If you’re not tech-savvy or not capable of debugging this issue, it’s highly advisable to proceed with the basic troubleshooting techniques available in this link.

After troubleshooting, below you’ll find a few solutions to rectify the issue.

Method 1 – Check The Cause of The BSOD Error

Two common causes of the KMODE_EXCEPTION_NOT_HANDLED issue are hardware incompatibility and faulty device driver or system service.

If you experience this error, check first if any of your newly installed hardware is compatible with Windows 10. You can find the required hardware for Windows 10 from this link. 

If all your hardware is compatible with Windows 10, you might need to check the device driver or system service. Review the bug check message. If any of the drivers you have is listed in the message, either disable or uninstall them before upgrading or setting up Windows 10.

You might also find it useful to check the System Log available in the Event Viewer for other error messages that can help you figure out the driver or device that’s causing the error. Running hardware diagnostics can also be useful.

Method 2 – Disable (or preferably uninstall) Software Before Upgrading

If you’re upgrading Windows 10 from Windows 7 or Windows 8.1, you might need to disable or uninstall the software first. First, try uninstalling your Antivirus utility before starting the upgrade. Restart a few times before starting the Windows 10 installation. If you’re upgrading using the Windows 10 update, make sure that you disconnect from your Wi-Fi or Internet LAN (Ethernet) connection as soon as the download reaches 100% before attempting to start the set-up. Other users also reported that the cause of the KMODE_EXCEPTION_NOT_HANDLED issue is BitDefender. If this is what happened in your case, it will show in the error message such as KMODE_EXCEPTION_NOT_HANDLED (bdselfpr.sys). Users reported that a common solution for this is renaming the file. In the case of BitDefender, try renaming it to bdselfpr.s__. However, make sure to do this cautiously. Sometimes, renaming a file will even do more damage than good.

Method 3 – Disable/Disconnect From Hardware

If you’re connected to any general USB devices (such a smart card reader), disable it. If your computer is connected to other external devices, disconnect all of them. Examples of this include gaming controllers, printers, external hard disk, USB keys, and other non-essential devices).

Method 4 – Other Troubleshooting Steps

Other troubleshooting steps include:

• Upgrade using an .ISO file, instead of directly upgrading from Windows Update. When you do this, make sure you’re disconnected from the Internet during installation. If the process started and you forgot to disconnected, it’s best to restart the installation.
• If you’re connected to a domain while trying to set up Windows 10, disconnect and use a local account.
• If you’re using a SCSI hard disk, connect a thumb drive with the drivers for your storage device. While Windows 10 is setting up, click on the Custom Advanced Option. Using the thumb drive, use the Load Driver command to load the SCSI drive.
• Another possible cause of this error is due to BIOS incompatibility. BIOS issues can be solved by upgrading your version of your system BIOS. If you don’t know how to do this, refer to your BIOS manufacturer’s website.

Method 5 – Use A Trusted Automated Tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

Windows 10 supports various devices to get connected to which makes it quite a flexible operating system. The connection varies on the fact that the device can be connected either with Bluetooth or other wireless and wired connection.

Option 3 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers.
