Fix mfewfpk.sys, Epfwwfp.sys Errors in Windows

High Dynamic Range or HDR is a technique that’s used to create lifelike videos which have improved and better dynamic range, especially when it comes to details. And as you know, Windows 10 supports the steaming of HDR videos as long as the display supports it and it comes with the option to enable the HDR Playback for Windows 10 Video Streaming apps. However, before you can get the best viewing experience, you need to calibrate the display further for HDR video on your Windows 10 PC. Take note that even when you have the HDR Playback feature enabled on your computer, you still need a display that supports it. To make sure that your display supports this feature, you can use the DirectX Diagnostic Tool to have the display correctly wired and have the latest WDDM 2.4 drivers installed as well as set the other settings properly. Once you’ve made sure that your computer’s display really supports HDR and you’ve already enabled the HDR Playback feature, now it’s time for you to calibrate. Remember that when you calibrate the display, you should make an external monitor your primary display if you are using it for HDR and then adjust the settings to your liking. And if you are calibrating for primary display, you need to disconnect all other displays.

Follow the given steps below to calibrate the display of your PC.

• Step 1: You need to open the Video Playback first. To do so, navigate to Settings > Apps > Video Playback.
• Step 2: Under the Video Playback settings, uncheck the “Don’t increase display brightness when watching HDR video on battery” checkbox or plug in your PC.
• Step 3: Next, click the “Change calibration settings for HDR video on my built-in display” link located on the right side.
• Step 4: After that, click on the Play button located on the left side to play the video. Then move the sliders to the left or right so you can start to calibrate. Once you see that the quality of the image is to your preference, stop.

Note: Just a tip when calibrating – you just have to find the right balance between the details in the darker parts of a scene. For instance, you have Mountains in the background and buildings in the front – you need to drag the slider to the right to add more details to the snow on the mountain or drag the slider to the left to add more details to the buildings. After that, you can pause the video and exit the full-screen mode. Keep in mind that the quality of HDR depends on you as it is a personal choice. Some users might like a brighter shade while other ones want the darker shade so it really depends on your taste. If you are not satisfied with how your HDR turned out, you can just try calibrating the display again. Simply go back to the default HDR video calibration and click or tap the Reset calibration button. Another thing to remember. First, you can only see HDR content on the full screen and if you’re using a laptop, you need to make sure to watch videos when plugged in and check that the battery settings won't’ lower the brightness.

The Intel Driver and Support Assistant automatically identifies, finds, and installs drivers in a computer and is pre-installed in newer Intel-supported systems. If you are using one of those newer Intel supported systems but encountered an error that says, “Communication with service process failed, Tray cannot start” when you launch a program, read on as this post will guide you in fixing this problem. This kind of issue in Intel supported system could be due to some third party application that’s meant to update drivers could be interfering. It is also possible that the Intel Driver and Support Assistant application is corrupted. Whatever the cause may be, here are some suggestions you have to check out to resolve the problem.

Option 1 – Try to uninstall all the third party driver update applications

One of the reasons why some users install third-party driver update software is that it is kind of tiresome to update each one of the drivers manually. However, as tiresome as it might be, it is still better than using a third-party driver update application as these kinds of applications could mess up the drivers, and the Intel Driver and Support Assistant is still much better. To fix the error, you have to uninstall the previously installed third-party driver update application on your computer.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the third-party driver update application you are using, select it and then click on Uninstall to remove it.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 2 – Try to disable the DSATray in Startup

Another thing about the “Communication with service process failed, Tray cannot start” error is that it keeps on popping up each time you boot your computer. And so to resolve this bug, you can just disable the DSATray from Startup. How? Refer to these steps:

• Tap the Ctrl + Alt + Del to pull up the Security options window.
• From there, select the option to open the Task Manager.
• Once you’re in the Task Manager, go to the Startup tab and look for “DSATray” and right-click on it and then select the Disable option.
• Now restart your computer and you should be good to go.

Option 3 – Try to reinstall the Intel Driver and Support Assistant

If the Intel Driver and Support Assistant is corrupted, you need to uninstall it from your computer. All you have to do is go to Programs and Features like what you did in the first option to uninstall the program. Once you’ve uninstalled it, download the newer or latest version of the Intel Driver and Support Assistant from the official site of Intel and then install it.

There is a built-in tool in Windows 10 the Disk Cleanup Utility which can help you restore hard disk space by removing temporary files, Thumbnails, old Windows files, Windows Upgrade logs, Delivery optimization files, and many more. However, from time to time, this built-in tool also experiences some issues. One of these issues is when it gets stuck on Windows Update Cleanup. Read on to find out what you can do in such a case. When the Disk Cleanup Utility is stuck on the Windows Update Cleanup, the process could be slow and take a long time to complete when purging the files. If this happens, click on Cancel to close the dialog box. After that, try running the Disk Cleanup Tool again as administrator and check if the files that you want to clean is still there or not. If it isn’t there, then this means that the cleanup has been done, otherwise, you need to refer to the options given below.

Option 1 – Try to manually delete the contents in the SoftwareDistribution folder

• 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 start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution 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.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer and then try to run Windows Update once more.

Option 2 – Try to manually delete the contents of the Windows.old folder

The Windows.old folder is the one that holds the older version of Windows when you upgrade. It comes really useful when you want to revert to the previous version of Windows 10. Thus, you can delete the Windows.old files in case the cleanup tool is stuck.

Option 3 – Try running Disk Cleanup in a Clean Boot State or Safe Mode

Another thing you can try is to restart your computer in a Clean Boot State or Safe Mode. Chances are, there are some programs that are preventing the Disk Cleanup Utility tool to run properly. After you restart your computer in a Clean Boot State or Safe Mode, try to run the Disk Cleanup tool again and then see if it now works or not.

Option 4 – Run the Windows Update Troubleshooter

You might also want to run the Windows Update Troubleshooter as it could also help in fixing this issue. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Run the DISM tool to fix the corruption in the Component Store

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /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.

As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more. So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.

Option 1 – Try to toggle the settings of the Internet Options

• In the Windows Search box, search for Internet Options to open it.
• Next, go to the Security tab and drag the security slider to the lowest possible security for all the given zones.
• After that, click on OK to save the changes made and close the Internet Options.

Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.

Option 2 – Try to update or reinstall the respective drivers

If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 3 – Try to change the PIN of the security key

If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.

Option 4 – Temporarily disable Firewall and third-party antivirus

Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.

Option 5 – Try to troubleshoot the web browser

Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.

Error 1310 is a fairly common type of error encountered by Windows users. Error 1310 usually generates while a user is attempting to install Adobe Photoshop or some Adobe product on Windows. The message displayed to the user usually states: ‘Error 1310. Error writing to file. Verify you have access to that directory’. Once the error message appears, the installation process will be terminated.

Solution

Error Causes

While there are different conditions that may trigger this error, most likely, they are generated because of the lack of privileges a user has on a Windows log-on. When this happens, the operating system doesn’t allow the user to access the installation files. Another reason Error 1310 may occur is that often users attempt to log on to the system and choose the ‘Only for me’ option rather than the recommended ‘Anyone who uses this computer’. Because of this reason, the data is locked for all the other users. Since Error 1310 can easily disrupt your workflow on the system and may also lead to annoying consequences, it is best advised to treat it as quickly as possible.

Further Information and Manual Repair

There are different solutions to resolve these errors that are briefly listed below as follows.

• First and foremost, restart the installation by logging onto your computer from the administrator account. This error will most likely disappear because there is often a lack of privileges that will trigger it. When you will log on from the admin account, you will have access privileges and such errors will be rectified.
• Fix any corrupt system files that exist on your system. If the file resides in the Windows directory, this error will be generated. Check if any of your system files are corrupt or damaged. If yes, make sure you repair and return them back to their original position.
• This error is sometimes caused because of incorrect registry entries. If the setup program shows errors, it is possible that it is because the system is having problems retrieving data stored in the system registry.
• Another way, this error can be avoided is to run the setup in compatibility mode. Compatibility issues are a common occurrence. However, when an installation is performed in the compatibility mode, one can easily steer clear of such errors.

Implement any of the solutions listed above and protect your system against Error 1310.

Microsoft store is ready and prepared for Windows 11 official release on October 5^th and it is coming with some surprises. It has officially confirmed that many open source and free applications will be in it like Opera, VLC, discord, Libre office, etc. It seems that Microsoft wants to place its store as one place to go for all of your software needs. Another great surprise is the coming of Epic games store implementation. It was officially confirmed but not explained in detail, will we have Epic store opened in Windows store or we will only get installer as a package we will see but this is some great news. As for how it states now, it seems that the Windows store aims to eliminate searching the web for applications and bring them all into one environment with reviews and ratings so you know which one to install and use. It also features a great search engine to find proper applications for your needs. The new store will come to Windows 10 as well but after all Windows 11 has been mostly released and adopted. So expect it via update in two or three months' time. It would be great if some larger companies decide to join MS stores like Autodesk, Adobe, the Foundry, etc so you can install everything you need from it but one can only hope.

Steam Deck release is almost upon us and more news comes to light. The Latest officially confirmed technical detail is that the user will have access to device's BIOS and that dual booting will be officially supported. This, of course, means that you will be able to have both Proton and Windows on your device letting you play anything that you wish if the hardware is strong enough. Valve also said that you can launch OS from an SD card! This of course will save space available for games themselves, especially for entry models with less than one available. All of this information really pushes Deck into the territory of a handheld PC and not just another console and I must admit that this announcement left a smile on my face.
