Fix mfewfpk.sys, Epfwwfp.sys Errors in Windows

SD memory cards have surfaced as standard cards for digital cameras and microSD as phone standard memory cards. Most people have and use at least one daily, so naturally copying files and even formatting SD cards is a natural thing to do, but what if you cannot copy files or format SD cards? Fear not because we had this issue and tried several things in order to overcome the problem and after some time here is a list of what can you do if you are facing this exact issue. The list is written from most simple solutions to more complex ones and it is advisable to follow it as presented. That being said, let's dive into solving the problem.

1. Remove Write Protection on SD card

First and in my experience the most usual thing preventing deleting, copying files, and formating SD card is due to write protection. Take an SD card out of the laptop, camera, or card reader and visually inspect it. On side of almost every SD card, there is a hardware lock switch and mark where it needs to be positioned in order to be locked. Even if the switch is positioned on unlocked state, switch it to locked and then back to unlocked. Sometimes this easy moving of switch can resolve some contact issues and the card will start working normally. Another type of lock that could be turned ON is a software one. If for any kind of reason data protection has been turned ON, you will need to turn it off in order to be able to format an SD card. In order to do this follow this guide:

1. Press ⊞ WINDOWS + R to open the Run dialog
2. In run dialog type in diskpart and press ENTER
3. Once diskpart is opened in command prompt type in: list disk and press ENTER
4. Locate your SD card and type in select disk x, where x is disk number followed by ENTER
5. After the SD card is selected type in: attributes disk clear read-only and press ENTER

This process will clear the software lock on the SD card, after following this method try to format the card again, if the problem still exists go to the next solution.

2. Format SD card using Command prompt

Command prompt is a great tool and can perform some commands that are not been able to be completed using file explorer or another tool inside Windows.

1. In the taskbar search box, search for cmd and select the Command prompt
2. On the right part select run as administrator
3. If needed click on YES on UAC prompt
4. Inside command prompt type in diskpart and press ENTER
5. type in list disk followed by ENTER
6. Select your SD card by locating its number in the list and typing select disk X, where is X SD cards number in list and press ENTER
7. Once SD card is selected type in format fs=ntfs quick and press ENTER

This should format SD card but if for reason even this step is provided as unproductive, go to the next solution.

3. Format your card with the Disk Management tool

1. Go into the taskbar and search for Disk Management and open it
2. Select SD card partition that you wish to format
3. Right-click on the partition and select format
4. After the format is done, enter the volume label, file system, and allocation unit size. Confirm with OK
5. Press OK again to confirm the formatting process.

If you have not managed to format your SD card even with this method go to the next solution.

4. Repartition card with Disk part

If all previous solutions have failed there is a chance that the SD card has bad sectors on it. If this is the case that we will need to partition cards in order to isolate bad sectors and use healthy ones.

1. Press ⊞ WINDOWS + R to open the Run dialog
2. In run dialog type in diskpart and press ENTER
3. Once diskpart is opened in command prompt type in: list disk and press ENTER
4. Locate your SD card and type in select disk x, where x is disk number followed by ENTER
5. Type in Clean and press ENTER
6. Type in Create partition primary and press ENTER
7. To select a new partition type select partition 1 followed by ENTER
8. Make partition active by typing active and pressing ENTER
9. Format the drive by typing format fs=ntfs label=SDCard quick followed with ENTER
10. Assign a letter to drive by typing assign letter=h followed with ENTER
11. Type exit to close Command prompt followed again by ENTER and open File Explorer to check if the drive is active

5. Try a dedicated SD card formating fool

If anything failed so far, one last thing you could do is to download and try a dedicated SD card formatting tool. One that I would recommend is SD Memory Card Formatter, which is free software make specifically for formatting SD memory cards.

As you know, Windows programs depend on several operations to get executed and at the same time, there are also numerous parameters that have to be fulfilled for a program to get executed. However, based on some reports, there was an error when some users tried to run a program. This error says, “The application was unable to start correctly (0xc00007b)”. There could be various reasons why this error occurs but the main one is most likely due to an x86 application that is not compatible with the x64-based operating system. To fix this problem, you can run the Check Disk utility or reinstall the application or the Microsoft .NET Framework. You can also try reinstalling DirectX or replace the corrupted DLL file(s). For more details, refer to the given options below.

Option 1 – Try running the Check Disk utility

• In the Windows Search box, type “command prompt” and from the search results, right-click on Command Prompt and select “Run as administrator”.
• After opening Command Prompt, type this command and tap Enter: chkdsk <Partition Letter>: /f
• The command you entered will start to check for errors and fix them automatically. Else, it will throw an error message saying, “Chkdsk cannot run because the volume is in use by another process. Would you like the schedule this volume to be checked the next time the system restarts? (Y/N)”.
• Tap the Y key to schedule Disk Check the next time your computer restarts.

Option 2 – Re-enable the Microsoft .NET Framework

You could also try to disable the Microsoft .NET Framework then enable the latest version of the .NET Framework on your PC and check if the error is fixed

Option 3 – Try to reinstall the program

There are times when some supporting module for your application under the hood could have messed up the application where you get the error. To fix this, you have to uninstall the program and then download its latest version from its official site and then install it again. Once you’re done, run the application and see if the error is fixed.

Option 4 – Run System File Checker scan

If reinstalling the program didn’t work, you can also try running the System File Checker or SFC scan to fix the error. 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.

• Reboot your computer.

Option 5 – Try running the DirectX Diagnostic Tool

Since the error has something to do with the DirectX Graphics APIs, you can run the DirectX Diagnostic tool to resolve the problem.

Option 6 – Try updating or re-installing DirectX

If the DirectX Diagnostic tool didn’t work, you can try to update or reinstall DirectX instead. This can help in fixing the problem because when you reinstall or update DirectX, it will replace the incompatible or corrupted components of DirectX from your computer.

Hello and welcome everyone. In today's article, you will learn how to lock folder and content in it. Please be aware of few things:

1. The method is shown here works, but you need to be careful and follow step by step or you will damage your files permanently,
2. If you forget your password, you can not access your files anymore
3. Your files altho protected can still show up in recent files of some applications

All of that being said, let us start with locking the local folder on the computer with the password. Go to the folder where you have files that you would like to hide and lock with a password. Enter the folder and create the new text file inside it. Skip the name for now and go inside it. Copy and paste the following code inside the file:

---

cls @ECHO OFF title Folder Locker if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK if NOT EXIST Locker goto MDLOCKER :CONFIRM echo Are you sure u want to Lock the folder(Y/N) set/p "cho=>" if %cho%==Y goto LOCK if %cho%==y goto LOCK if %cho%==n goto END if %cho%==N goto END echo Invalid choice. goto CONFIRM :LOCK ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" echo Folder locked goto End :UNLOCK echo Enter password to Unlock folder set/p "pass=>" if NOT %pass%==Your-Password-Here goto FAIL attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker echo Folder Unlocked successfully goto End :FAIL echo Invalid password goto end :MDLOCKER md Locker echo Locker created successfully goto End :End

Error Code 22 - What is it?

Code 22 is a type of Device Manager Error code. Device manager errors are reported by the drivers causing the problem. It indicates that the devices are disabled in the Device Manager. This error code is displayed in the following format:

This device is disabled. (Code 22)

It looks like a very simple matter to enable a device from the Device Manager interface but if the device fails to load then there are likely greater underlying problems with the drivers. Drivers allow hardware devices to communicate with other hardware devices and the operating system. Drivers contain instructions and operating procedures for devices. Without a driver, a hardware device will not function and may not even appear in the Device Manager.

Solution

Error Causes

Common causes of error code 22 are:

• Device is disabled
• Driver is outdated
• The driver is missing or corrupt
• The previous attempt to update the driver failed
• Device is damaged
• The device is not configured as the default device

This means that though the error code 22 typically indicates that the device reporting the error is disabled but other causes can also be associated with the error occurrence.

Hello everyone, in today's tips and tricks we will focus on providing you with various solutions on how to solve the Device not migrated error that appears after the Windows update has been performed. Sometimes sadly updates to our operating systems can introduce us to various issues that look scary but in reality, they are solvable and not so scary at all. After all who would not find this message concerning, especially when it happens in the middle of work. The first thing that would pop into my mind is that I have lost tons of work and that something in my hardware has gone very wrong and it is dead. Luckily that is not the case and this error means that due to Windows update drivers were not properly transferred due to some compatibility issues, maybe it was a corrupt update file, etc. Of course, the reason could be hardware malfunction as well, but if everything was working fine before the update, it is a software issue, and I must say it is a common one and fixable. Please keep reading this guide in order to fix the Device not migrated error.

1. Update the Driver

   You should always try this first, if the device is not recognizable, try updating its driver and see if the problem vanishes. In order to update the driver, we will need first to locate which device has not been migrated properly, we will do this with help of a search engine on the internet like google for example. So open your browser of choice, go to a search engine (google for example) and type in the search box first line from your error message, yes, that scary one. You will be given which device has malfunctioned and was not migrated properly, now we will locate the device and update its drivers. To do this press WINDOWS + X on your keyboard to bring up Windows secret menu and choose device manager. Find device inside device manager, right-click on it, and choose properties. Go to the events tab and make sure that the device has migration issues. You have now 3 options for updating the driver, you can do it manually, automatically, or with the driver installer. We will cover all 3 options so you choose which one best suits you. OPTION 1: Manually. Close the Properties tab, go to the device manufacturer website and download the latest driver, if there are no drivers there, the only executable installer for the device skip this step and try the other 2. After you have downloaded the driver package from the website, right-click on the device and choose update driver. Now navigate to the folder where you have downloaded your driver package and update the driver. Reboot your system. OPTION 2: Automatic update. Close the Properties tab, right-click on the device and choose to uninstall. Once the device is uninstalled, restart your system, and Windows will automatically search and install the latest driver for the device. OPTION 3: Via driver installer. If you have downloaded .EXE or executable driver installer from device manufacturers web site try installing it, if the installation fails, try using compatibility mode for the installer. Navigate where the installer is located, right-click on it, and choose properties. Go to compatibility TAB and try installing it with administrator privileges in Windows 8 mode. Reboot your system after this step. This should solve the issues, however, if the issue still persists, follow the next steps.

2. Verify the Corrupted System Files

   Press WINDOWS + X on the keyboard to open the hidden system menu and choose Command prompt (administrator) In the command prompt type in: sfc /scannow and press ENTER. The scanning process and repair of files will take around 15 min. Leave it to finish completely, do not restart, work on the computer or shut it down while the process is active, and only after it is finished reboot your system.

3. Update Windows.

   If your Windows is not updated sometimes this issue can be resolved by updating it on the latest version. Click on start and then on settings. Once the settings screen is opened, find and click on Update and Security. Go to the Windows update tab and click on DOWNLOAD or click on check for updates for the latest Windows fix.

4. Reset BIOS to factory settings.

   Sometimes BIOS not being properly configured can cause issues in Windows itself and prevent it from detecting PnP devices thus creating this error. Restoring BIOS back to the factory setting can help. Turn off your computer and turn it back on. Press delete, f12, f11, or any other key which will take you to BIOS (default key is delete but sometimes manufacturers map this to another one. Once your screen turns ON you will see in the bottom message which key needs to be pressed in order to enter BIOS). Sadly since every BIOS could be different we can not cover step by step guide for each but you need to find the option where you load BIOS defaults, click on it save, and exit. Your computer will restart and boot into Windows, check to see if the problem still persists.

5. Update BIOS

   BIOS can cause issues with certain PnP devices when the newest Windows update is rolled. If reverting BIOS to the factory setting has not been successful try update. Go to your motherboard manufacturer website, find the update and read step by step guide there since updating BIOS differs from version to version and from manufacturer to manufacturer. After the update is done, restart the computer and hopefully, the error is gone.

6. Perform a System Restore

   If everything else fails, perform a system restore to get Windows back into the state before the update was installed and when everything was working fine. Press WINDOWS + R on the keyboard to open the run dialog. In the run dialog, type control panel and press enter to enter control panel, locate recovery and click on it. Inside the recovery screen click on Open System Restore. Choose a date when everything was working in order, the best bet is the date before Windows update and roll it back. Click on date, and then on next.

If you suddenly find the middle mouse button not working as you use it on your Windows 10 computer, then you’ve come to the right place as this post will provide some suggestions that can help you fix the issue. This kind of problem can affect your experience in using your computer as the middle mouse button helps you in scrolling through long web pages and screens with a lot of data. So if that stops, you will end up using your keyboard instead which is kind of a hassle compared to using the middle mouse button. It is possible that this problem could have something to do with either the hardware or software. To isolate the possibility of a hardware failure, you can try to connect the mouse to a different computer and see if it works just fine there or if it still has the same problem. If the mouse works properly on a different computer, then the issue is software-related. It is possible that a software update, especially gaming software, could have been misconfigured in a way that the middle button does not respond like it’s supposed to. To resolve the problem, you might want to try reinstalling or updating the mouse drivers or run the Hardware and Devices troubleshooter. You can also install OEM-specific mouse drivers or modify some entries in the Windows Registry.

Option 1 – Reinstall or update the Mouse driver

The problem may be caused by a corrupted or an outdated mouse driver. To fix it, you have to update or reinstall the mouse driver. How? Follow these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the Mouse and other pointing devices and right-click on the mouse driver 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, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 2 – Try running the Hardware Troubleshooter

The next thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try to install OEM specific mouse drivers

Aside from updating or reinstalling the mouse drivers, you might also want to try installing OEM-specific mouse drivers. When you install Windows, it will use a generic driver for all its components. The disadvantage of generic drivers for the mouse is that it limits its functionality. In fact, some also configure the middle mouse button to respond to specific action which does not work without the correct drivers. In such cases, you need to visit the website of your computer’s manufacturers to download and install the latest drivers and then open the software and configure it the way it was before. Keep in mind that some OEMs also offer gestures, so you also have to check on that.

Option 4 – Try to modify some entries in the Registry

If a Windows Update is the one that caused the problem, you could correct it by making some modifications in the Registry but before you proceed, make sure that you create a System Restore point first.

• Tap the Win + R keys to open the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelDesktop
• After that, double click on the “WheelScrollLines” entry on the right pane to open its Properties.
• Now change its value data to “3” and exit the Registry Editor and then see if the issue with the middle mouse button is fixed or not.

A recent update in Windows 10 has caused a couple of glitches. One of these glitches is having trouble signing into Windows 10. Some users reported that they were not able to sign in to their computers using a PIN and they weren’t also able to reset it either.

The Windows 10 system allows users to change the default location of the User folders to another drive. This is probably to make sure that the files stay safe in case the system suddenly crashes. However, in some cases, while changing the path to another drive, for instance, the D drive or any folder, the Windows system recognized it as a hard drive as well so even though the files will be saved on that folder, it will appear as a hard drive in the Windows Explorer or look merged with another folder. It could also be that you had dragged and dropped a user folder to another user folder by accident. So if you’re wondering how you can unmerge the User folders, read on as this post will guide you on how exactly you can do that. Take note that even if you try to use the File History to restore the User folders, it still won’t work and you won’t be able to move them back to their previous locations nor restore the folders back to their previous versions and it would only state that they are not available. In the instructions given below, we are using the Downloads folder as an example.

• Step 1: Tap the Win + R keys to open the Run dialog box.
• Step 2: Next, type “Regedit” in the field and hit Enter to open the Registry Editor.
• Step 3: After opening the Registry Editor, navigate to the following registry key:

ComputerHKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerUser Shell Folders

• Step 4: Then double-click on the multi-string value {374DE290-123F-4565-9164-39C4925E467B} located in the right hand pane. And in the Value Data, copy and paste the following value:

%USERPROFILE%Downloads

• Step 5: Now click OK and close the Registry Editor.

Note: Look close enough and you’ll see that the multi-string values belong to each one of the folders. From there, you have a Desktop, Favorites, Skydrive, Music, Pictures, and many more.

• Step 6: Restart your computer. After that, the operating system will pick up the new folder location during the startup. Here are the values for the other folders:

Music – {1CF1260C-4DD0-4ebb-811F-33C572699FDE} Pictures – {3ADD1653-EB32-4cb0-BBD7-DFA0ABB5ACCA} Videos – {A0953C92-50DC-43bf-BE83-3742FED03C9C} Documents – {A8CDFF1C-4878-43be-B5FD-F8091C1C60D0} Desktop – {B4BFCC3A-DB2C-424C-B029-7FE99A87C641}

• Step 7: Now all you have to do is to change the location correctly. Start by tapping the Win + E keys to open the Windows File Explorer.
• Step 8: After that, right-click on the Downloads folder located in the right-hand pane.
• Step 9: Then click on Properties and go to the Location tab then type “D:\Downloads” in the location box.
• Step 10: Click the Apply button and then the OK button to save the changes made. Doing so would ensure that not only the Downloads folder is restored but also that it does not stay merged to another folder or appear as a drive.
