How to avoid errors in Windows

Recently, a few users reported that they were unable to turn on their computers for some reason and at the same time their computers Computer makes a beeping noise couple of times or continuously whenever they try to turn them on. The sounds the computers are making can be quite annoying and it also signifies that there is something wrong with them. The problem might have something to do with the hardware inside of the computer system rather than Windows 10 itself. As you know, a computer is designed to deliver audible error sounds every time some part of the hardware is not properly working. For instance, if you hear a single beep, this indicates that your GPU is having some issues and if you’re hearing two beeps, it indicates that your RAM is not working properly, whereas three beeps that repeat after a pause when you turn on your computer means that there is something wrong with the system memory. On the other hand, if your computer is beeping continuously, this means that the problem lies with the processor. To fix this issue, here are some suggestions that might help but before you proceed, make sure that you know how to manage your computer’s hardware, if not, better have some expert do it for you.

Option 1 – Try checking the RAM

One of the basic things you can do in this kind of case is to check the RAM. Prepare some screwdrivers and dig into your PC and then look for the RAM slots and ensure that they are attached firmly. There are times when moving around your computer daily can cause certain components in your computer to become loose. Worst case scenario is that the RAM might be broken so really have to replace it.

Option 2 – Try checking the graphics card

After digging into your computer, check the graphics card and give it some good cleaning. As you know, you have to remove certain components like the graphics card regularly and clean them to help increase their lifespan and avoid errors in a startup. And if it turns out that the graphics card is broken, you have to replace it with a new one to fix the problem.

Option 3 – Try checking the processor

The processor is the brain of every computer so if it ends up not working, everything else is useless. Thus, you need to check it to see if it’s firmly attached and see if it needs some cleaning of dust and other debris. After that, try turning on your computer again. If it doesn’t work, then you might have to take your system to a technician to resolve the problem for you.

Blackouts are one of the most annoying things that can happen in the modern age. We have all learned to depend on electricity, maybe too much, so having a backup plan in these unpleasant situations is necessary. Here are some good gadgets for these kinds of situations.

Power Bank

The fully charged power bank is a great item that could fill up your phone or tablet. If it is a larger power bank it could fill them up all the way to the top several times and having charged phone or tablet can help greatly with some fun during dark times. The power bank can also be used to fill up other gadgets on this list so if the power outage is expected to last longer perhaps it would be wiser not to waste it on phone/tablet games.

Portable Generator

If the power bank is too short-lived for your needs, a portable generator is always a good option since it can provide power for longer time periods. The solar generator is what we recommend because it is much cheaper to produce electricity but it is limited if a power surge comes at night, one on gasoline is more stable and practical but it costs more to produce electricity.

Portable Solar Charger

One more electric-producing device on the list, this one however is aimed at charging your phone, tablet, or laptop by harvesting Sun's energy and turning it into valuable electricity for your devices. Fully silent and easy to operate this is a great tool for power outrage. It will not be able to produce electricity for smaller house appliances but for basic phone/tablet/laptop needs it will suffice.

Panic light

Self-sustained with its own battery, panic lights are great assets for lightning when power is not present. They can turn automatically when the circuit detects that power is missing but can be also manually switched on or off. There are many versions of panic lights ranging from the light they produce to how long can they work so picking the right one will depend entirely on your home size and needs.

USB Headlamp

If you lack panic lights USB headlamp is a great choice to light your way and it works even better than a flashlight, although a flashlight is also a great tool, a headlight will provide you with free arms to do various things that you would not be able to by holding a flashlight. Modern headlights come with LED lights so they provide a good amount of light with small power consumption and they can be recharged in a power bank, solar charger, or generator.

LED lantern

LED Lantern is a gadget sitting somewhere between a headlight and a panic light, it offers around the same light amount as a panic light but you can carry it around with you. Of course, it will drain its battery faster than a panic light and it will still need to carry around but it can offer some good options when you need it, like taking it with you to the toilet.

Electric Lighter

An electric lighter is also one of the things that you will need, it can ignite candles, paper, stoves, etc. Its battery is usually enough for extensive use and there are small chances that it will need to be recharged. Having matches is also smart, just in case.

Solar Oven

Great gadget when outbreaks last long or when you get hungry. Not all households have gas ovens so a Solar oven is a great tool to keep you full of food. Granted it will not be on par in speed and quality with a regular oven but when it is the only option it will suffice.

If you encounter an error saying, “error accessing the registry” when you try to merge a registry key on your Windows 10 computer, you’re not alone as some users also experienced the same problem. According to these users, they encounter the error after they’ve re-installed their Windows version and tried to open a .reg file. Based on the reports, this error could occur if the registry file does not have administrative privileges. Meaning to say, the program does not have the necessary permission to merge the .reg file. This is common with fresh installs as well as reinstalls. Moreover, this kind of issue could also occur due to system file corruption. Whichever the case may be, here are some troubleshooting tips you can check out to resolve the error.

Option 1 – Try to import the .reg file with admin privileges

As pointed out, the error may be due to a lack of admin privileges. It could be that the Registry Editor does not have admin privileges to merge the registry file. This is common with new Windows installations especially since the Registry Editor hasn’t been opened before. So you need to import the .reg file again and this time, with admin privileges.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and tap the Ctrl + Shift + Enter keys to open the Registry Editor with admin privileges.
• A User Account Control or UAC prompt will appear where you have to click Yes to proceed.
• After opening the Registry Editor, go to File > Import using the ribbon bar at the top.
• Next, use the import menu to go to the location of the file you were trying to merge. Once you’ve found it, click Open to merge it with your current registry. This should fix the problem. If not, refer to the next options below.

Option 2 – Try performing a System Restore

Running System Restore can also help you fix the error when accessing the Registry. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap 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.
• Once the next startup is complete, you have to merge or import the file again and see if the error is now fixed or not.

Option 3 – Try to perform repair install by creating a Windows 10 installation media

• Click this link and then click the Download Tool Now button.
• Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Now select the ISO file option in step 5.
• After that, you should now have an ISO file.
• Next, go to the location where you’ve downloaded the ISO file.
• Then right-click on the Windows 10 ISO file and select the Open with option and then select File Explorer.
• Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Option 4 – Try running the System File Checker Scan

As mentioned, the error when accessing the Registry might be caused by file corruption. And that’s where the SFC scan comes in. The SFC or System File Checker scan could detect and automatically repair damaged system files. 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. 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.

• Now restart your computer.

Many Windows 10 users use a Bluetooth headset as these kinds of Audio devices, as you know, lack wires since wires tend to get entangled and break which could get quite inconvenient. This is why using a wireless headphone is more preferable since it’s much simpler, however, using a wireless headphone also means it comes with a charging requirement and if it fails to charge, there is no music or audio or anything that you need a Bluetooth headphone for. However, wireless headphones are also susceptible to problems as you might encounter some problems when connecting your wireless headphone to your Windows 10 computer. One of these problems include when you try to get sound from the wireless device but nothing happened. This indicates that the Bluetooth headphone is disconnected in some way for some unknown reason even if you’ve already plugged it in. Thus, if you encounter this scenario, then there are several options you need to check out to fix the problem. To start troubleshooting the problem, here are the options you need to use as a reference.

Option 1 – Try turning off the device and turning it back on

The first thing you can do to resolve the problem is to turn off your wireless audio device and wait for a couple of seconds before you turn it back on. In most cases, this should fix the problem. In fact, you can also try to unpair and pair the Bluetooth audio device and see if it fixes the problem or not.

Option 2 – Try to set the headphone as the default device manually

There are times when you plug a headphone, it does not toggle the default audio device. Thus, to fix this issue, you have to set the default audio device to the headphones manually. To do that, follow these steps:

• First, right-click on the volume icon located on the system tray.
• Next, select the Open sound settings option to open the Sound section in the Windows 10 Settings app.
• After that, go to the Output section and select Headphones for the “Choose your output device” option. This should fix the problem for you.

Option 3 – Try running the Bluetooth Troubleshooter

As you know, Windows 10 has various troubleshooters with user-friendly interfaces where you can utilize them to fix issues in your PC. And since you’re dealing with some Bluetooth problem, you have to run the built-in Bluetooth Troubleshooter. To do this, follow these steps:

• Open the Windows 10 Settings.
• Then go to Update & Security > Troubleshoot.
• You should find the option for Bluetooth on your right-hand side – click on it then click on the “Run the troubleshooter” option.
• Now follow the next screen options.

Option 4 – Try to update or reinstall the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since then you have trouble in removing the Bluetooth devices and so to fix the issue, you can update, roll back or uninstall the Bluetooth drivers. How? Follow the steps below.

• Tap the Win + X keys to open the Device Manager.
• Next, look for the Bluetooth device and right-click on it.
• Select the option “Update driver”.
• After that, a new popup window will appear. In there, select the option, “Search automatically for updated driver software”.

Note: Checking the update may take a few minutes so you’ll have to wait until it finishes. If it is able to find an update, you must install it. And if you want to reinstall the Bluetooth driver, just select the “Uninstall driver” option and follow the next on-screen instructions that follow.

There are instances when instead of fixing problems the Windows Update brings you problems on your Windows 10 computer. You might even see some pending Windows Updates which for some reason, refuse to install no matter what you do. The good thing is you won’t have to deal with those failed and pending updates that are incompletely downloaded to your PC as you can actually delete them. Follow the instructions prepared below to delete the failed and pending Windows Updates.

Step 1: The first thing you have to do is delete all the contents in the Temporary folder

• Tap the Win + R keys to open the Run dialog box.
• Next, type in “%temp%” in the field and hit Enter or click OK to open the Temporary folder.
• From there, select all the folders and files within the Temporary folder and then delete them all.

Note: %temp% is one of the many environment variables in Windows that could open the designated folder by Windows as the Temporary folder which is usually located at C:\Users[username]AppDataLocalTemp.

Step 2: Next, remove the pending.xml file

• Go to the C:\Windows WinSxS folder.
• Once you’ve opened the folder, look for a file named “pending.xml” file and right-click on it and you can either rename it or delete it.
• After that, the Windows Update should delete the pending tasks and build a fresh new update.

Step 3: Delete all the contents of the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, got to the C:\Windows\Software\Distribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Step 4: Try resetting the catroot2 folder

You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process.  So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.

As you know, the Windows 10 operating system, as well as other Windows versions, comes with the Windows Firewall. In Windows 10, the firewall allows users to install and run a third-party firewall. This kind of firewall works independently to block any suspicious activity on your computer. However, recently, some users reported that they are getting a notification on the Startup saying,

“Windows Firewall and <Third party firewall name> Firewall are both turned off; tap or click to see available options”.

This particular error could be caused by a lot of factors but when you manually check the firewall, you’ll find that there really is nothing wrong with both the Windows Firewall and the third party firewall. So if both the Windows Firewall and third-party firewalls like McAfee, Comodo, and many others are both turned off in Windows 10, then you need to do several things to resolve the problem – you need to check the supporting services that are required and uninstall and then reinstall the third party firewall on your computer. For more instructions, refer to the options provided below.

Option 1 – Try enabling all the supporting services for the firewall

The first thing you can do to resolve the error with the firewall is to check all of its supporting services by following these steps:

• Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
• Next, look for the Windows Defender Firewall service among the given list of services.
• Once you found it, make sure that its Startup Type is set to Automatic and that the status of the service is Running. So if it’s not running, just click on the Start button.
• In addition, you also have to make sure that the following services’ status is set as follows:
  • Xbox Live Networking Service: Manual
  • Base Filtering Engine: Automatic
• Once done, start the firewall again and check if the error is now fixed or not.

Option 2 – Try to uninstall and reinstall the third-party firewall

It is possible that the firewall error might be due to an error with the compatibility of the installation in Windows 10 and the third-party firewall. Thus, the next thing you can do is to uninstall the third-party firewall and then reinstall it again. Once you have uninstalled the third-party firewall, you can download its latest version from its official website and install it again. This should fix the error with the firewall.

If you suddenly encounter a Blue Screen error that points out to either the mfewfpk.sys and epfwwfp.sys files, then this post might help. Both of these files are created by third-party software. The mfewfpk.sys file is created by the McAfee security software while the epfwwfp.sys is created by the ESET Antivirus. These files are residual files and sometimes it blocks upgrading Windows 10. Aside from blocking Windows 10 upgrade/update, these files can also cause a Blue Screen error after an upgrade which leaves your Windows 10 computer useless. When you get a Blue Screen error caused by any of these files, you will see an accompanying error message that states, “DRIVER IRQL NOT LESS OR EQUAL”. To fix this Blue Screen error, you can check out the suggestions laid out below but before you do that, you need to create a System Restore point first as it can help you undo any unwanted changes. In addition, make sure to also boot your computer into Safe Mode with Networking before you troubleshoot.

• After the scan is completed, restart your computer and see if it fixed the Blue Screen error.

Note: You can also use the ESET AV Remover tool to uninstall Eset security software to remove the epfwwfp.sys file.

Option 2 – Try to remove the mfewfpk.sys file

The same with the first option, you can remove the mfewfpk.sys file using CMD.

• First, right-click on the Start button and click on Command Prompt (Admin) from the menu to open Command Prompt with admin privileges.
• After, type the following command and hit Enter to delete the epfwwfp.sys file:

DEL /F /S /Q /A “%systemroot%System32driversmfewfpk.sys”

• Once the scan is completed, restart your computer and see if it fixed the Stop error.

Note: You also have the option to remove the mfewfpk.sys file using McAfee Product Removal tool to uninstall the McAfee security software. All you have to do is download the McAfee Product Removal tool and run it and then follow the onscreen instructions to install it. Once it is installed, click on Next. After you select the radio button to agree to the terms of use, click on Next once again. Finally, restart your computer and check if it is able to resolve the problem or not.

Option 3 – Run the Blue Screen Troubleshooter
