How To Fix the I/O System Error

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, just a few years ago we had FLASH video content on the internet, we had FLASH games, full FLASH website experiences, and more, but then flash was shut down mostly due to security reasons meaning that in just a few months we have lost most of FLASH web content. However, there is still FLASH content on the internet even today, there are still FLASH videos and flash games, but we can not play any of that content since browsers do not support FLASH and you can not get the FLASH plugin for browsers. So what might be the solution for this situation?

Ruffle and FLASH emulation

Emulation of course. We will not be able to get the flash player working, well at least not the original and official one, but we can make flash content playable again inside our browsers. The first thing is first, we need to get an emulator package from the internet in order for this trick to work, one we will be using is RUFFLE. It is lightweight, it is free, it is open source and it is reliable, everything we need. Download RUFFLE from its official website here. For Chrome and Edge download the ZIP package, for Firefox, go to the Firefox section of the tutorial. There is also a desktop version of RUFFLE there so if you are keen on playing your flash content on your desktop computer you might well grab that as well, but for the sake of this tutorial where we are enabling flash in our browsers, we will not focus on that part since it is pretty straightforward. Now once you have downloaded the RUFFLE emulator, please extract it to the desired folder somewhere on your computer. Once it is extracted, start your browser of choice and follow instructions.

FOR CHROME:

1. Navigate to: chrome://extensions/
2. Turn ON developer mode in the top right corner
3. Click on Load unpacked
4. Navigate to the folder where you have extracted RUFFLE

FOR EDGE:

1. Navigate to: edge://extensions/
2. Turn ON developer mode on the bottom left corner
3. Navigate to the folder where you have extracted RUFFLE
4. Turn RUFFLE ON

FOR FIREFOX:

1. Go to the RUFFLE download page, we can not use the zip package we were using for Chrome and Edge
2. Right-click on the Firefox download link
3. Save link by clicking on Save link as...
4. Navigate to about: debugging
5. Click on this Firefox
6. Click Load Temporary Add-on
7. Select the .xpi that you have downloaded

BONUS:

If you want to enable FLASH content live on your website use:  <script src="path_to_ruffle/ruffle.js"></script>

The screen flickers into black, it comes back and on-screen there is a message Driver stopped responding and has recovered. If you have been through this you are aware that the issue is not serious but it can get pretty annoying fast since you are not aware when will it happen again, and it will happen again. In this guide, we will go through the usual reasons for this error and offer solutions to them. Follow the guide step by step in order to resolve the problem.

1. Clean your PC Dirt and dust are your enemy no1, dirty graphic card can not be properly called and can cause overheating which can result in this particular error, make sure that your PC is clean and tidy in order to eliminate dust and dirt as a cause for malfunction.
2. Turn off multiple applications and try running just one at a time Overburdening GPU can cause this error to appear since the graphic card can not handle all requests it gets from multiple active applications. Try to run just one application at a time for some time period to see if the error will appear again.
3. Update driver Update your GPU driver to the latest version from the manufacturer's website, Display Driver Stopped Responding and Has Recovered Error in Windows 10 can be from outdated drivers not able to handle modern tasks
4. Get newer GPU As hard as this advice is, sometimes the reason is an old graphic card that simply can not keep up with modern games and applications, upgrade it to a more modern GPU and watch errors go away.

As previously announced by Google feature to quickly delete the last 15min of browsing history via one button is rolling out now. For now, only Apple users will be available to use this feature but the Android update is scheduled for later this year, a strange move by Google but it is what it is. For anyone who is unfamiliar with this feature, basically, Google wants a quick way to remove the last 15min of browsing history as a supposedly stated request to make deleting browsing history much easier. Google came up with this idea so you can keep the previous history intact but remove just 15min time frame, no additional explanation was given on why 15 but I presume it is some round number that came up as the middle one with research, read telemetry info. Using quick delete requires being signed into Search with a Google account. Users can access the option by simply tapping on the avatar icon to access the settings then choosing "Delete last 15 minutes."

Error Code 0xC004C770 – What is it?

If the Error Code 0xC004C770 popped up on your computer during your activation of the Windows 10 software, don’t worry. This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.

Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.

Solution

Error Causes

Error Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer. If you have a multiple-use license, the product key that you are entering may already have been used for the maximum number of computers allowed under that license.

Further Information and Manual Repair

There are two basic methods for addressing the issues associated with Error Code 0xC004C770. These methods can easily be implemented by anyone who is comfortable interacting with the Windows Store from their computer, which makes the resolution of this particular error code fairly simple and straightforward.

If you are unable to complete the steps below or Error Code 0xC004C770 has not been resolved after following the guides below, contact a Windows technician who is familiar with the Windows 10 activation process to assist you in the process. You can also get in touch with the Windows technical support team to assist you in the process if needed.

Method One: Purchase A New Product Key from Windows

If you have already used the product key on another computer or have used it on the maximum number of allowed devices, you may need to purchase an additional product key for the computer with Error Code 0xC004C770. Product keys can be purchased physically from a retailer that sells Windows 10 software licenses or purchased directly from the Windows store.

To purchase a new product key directly from the Windows Store, follow the steps below:

• Step One: Select the Windows start button at the bottom of your toolbar. Click on “Settings,” then select the option for “Update and Security.”

Both the DISKPART utility and the Disk Management are useful tools in Windows 10 that manage the disk space allocation, and so on. But these tools are not without errors as you could also encounter some when you run them. Recently, some users reported getting an error that says, “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility”. Here’s the exact message of the error:

“The selected disk is not a fixed MBR disk. The ACTIVE command can only be used on fixed MBR disks.”

This kind of error only occurs when you try to activate a disk partition on a UEFI system partition. However, the command works only if your computer is based on BIOS/MBR. The UEFI method has no concept of the active partition and since you have a UEFI system, the disk type is GPT instead of MBR. To simply put it, your BIOS needs the MBR disk type while the UEFI needs the GPT disk type. To fix the “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility” error, there are various potential fixes you can try. You might have to disable Secure Boot, convert the disk to MBR or fix the Boot Manager. For more instructions, follow the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try converting the disk to MBR

You can try to change the File System of the drive from GPT to MBR but before you do so, make sure that you create a backup copy of your data to an external drive. Once you have that covered, follow the steps below.

• Create a bootable Windows 10 media and boot your computer from it.
• Next, click on the “Repair your computer” option on the first Windows 10 installation setup window.
• Afterward, select the operating system partition from the given options and click on Next.
• Now select Command Prompt within the System Recovery options box and execute this command to initiate the Diskpart utility: diskpart
• Then type either one of these commands to view the list of all the Disk connects or the partitions on those disks formed: list disk or list volume
• After that, execute another one of these commands depending on the command you previously entered to select the disk or partition you want to select: select disk # or select volume #
• Now execute this command to clean your drive: clean
• Finally, execute this last command to convert the selected disk or partition as MBR: Convert MBR
• Restart your computer and check if the error is fixed.

Option 3 – Try to fix the Boot Manager

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
  • bootrec /FixMbr
  • bootrec /FixBoot
  • bootrec /RebuildBcd
• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed error code 0xc000014c.

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.

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
