Error code 0Xc004F074 - What is it?

Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074. Error code 0Xc004F074 is manifested when the user fails to activate Windows directly after the installation of Windows 10. This occurs if the previous operating system on your computer was Key Management Service (KMS) activated.

The KMT provides a more seamless operation when users are activating volume license editions of Microsoft Windows and Office. This process tends to be clear to end-users of the system.

Symptoms of error code 0Xc004F074 include:

• Windows is unable to reach your company’s activation service.
• The Key Management Service is unavailable.

Solution

Error Causes

Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).

Further Information and Manual Repair

To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:

1. Method 1: Update Your KMS Host 9 (Windows Server 2003)

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

There are times when you might notice that the Drive letter from the File Explorer is missing, right after you install an update in your Windows 10 computer. So if you are facing this issue right now, then you’ve come to the right place as this post will guide you on what to do to fix it. In case you don’t know, a drive letter represents a single alphabetic character which is through A-Z typically. This could be assigned to a physical disk partition, floppy disk drive or the removal device/ CD-ROM/ mapping network drive in your PC. In most cases, the drive letter “C:” is assigned to the first disk partition where the running Windows is installed. Thus, if the assigned letter is missing from either the Disk Management or the Windows File Explorer, it could result in inconveniences or will leave the partition inaccessible. To fix this problem, you can try to show the missing drive letters manually or make sure that the drive has a drive letter assigned in the Disk Management as well as assign the letter using a tweak in the Windows Registry. For more details, refer to the options provided below.

Option 1 – Try to show the missing drive letters manually

• Open the Folder Options from the Start Search and go to the View tab,
• Next, scroll down on the list of given options until you see the “Show drive letters” option and then check the box that’s marked against this option.
• After that, click on the Apply and OK buttons and then go back to the “This PC” window. You should now see the drive letters

Option 2 – Make sure that the drive has a drive letter assigned in Disk Management

As you know, every drive is assigned a drive letter in Disk Management. However, if it goes missing, you can still get it back through Disk Management. To do so, follow the steps below.

• Open Disk Management and from there, right-click on the menu of a partition or volume and you should see a function named “Change Drive Letter and Paths”.

Note: This function allows you to add the drive letter, remove the drive letter and change the drive letter. If the last option, namely, “Remove”, is selected and applied, the letter of the drive will be removed and won’t appear in Disk Management. Thus, this could be one of the reasons why a drive letter is missing.

• You need to click on “Add” to assign a letter to the selected drive in order to reverse the change. Note that you must assign the drive with the original letter because if not, the programs that rely on the original letter might not work as expected.
• If the original letter is already taken by a new drive, you need to change the letter of that new drive to another available letter.
• Then allocate the released letter of the targeted drive.

Option 3 – Try assigning the letter using a Registry tweak

The next thing you can do to fix the problem is to assign the letter using a tweak in the Windows Registry but before you do that, make sure that you create a System Restore point first, after that, follow these steps:

• Tap the Win + R keys to open Run and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMMountedDevices
• From there, check if a device is shown as being mounted at the specific drive letter and then right-click on that drive letter.
• Select the “Rename” option from the right-click menu to change the letter to any other available letter.
• Exit the Registry Editor and restart your computer.

Option 4 – Try to format the destination drive

Formatting the drive can also help you resolve the error. To format it, follow these steps:

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

Building a custom PC is a great feeling but it can sometimes not be ideal and we are not talking about breaking or losing parts. What we mean is that choosing the right components can be sometimes a difficult task. Of course, picking a PC case can have its issues, choosing the right power supply can be tricky but pairing all components together, especially CPU and GPU can be tricky. Builders with no depth knowledge and experience can sometimes choose improper CPU or GPU, picking one of them to be much more powerful than another thus not using it to its full potential because another component cannot handle stuff at the same speed. In order to not be trumped by this kind of stuff, there is a website that is completely free and you do not even need to be registered in order to use it. Bottlenet calculator link here What is even better, once you input your components you will get advice on what to change in order to tweak the system a little more to avoid bottlenecks even more. It is a very useful tool and we are advising you to use it in order to save money but not throwing it on some component that will be half used.

If you are trying to copy a file but suddenly encountered an error message saying, “An unexpected error is keeping you from copying the file”, then you’ve come to the right place as this post will help you resolve the problem. This error comes along with another message that states, “Error 0x80070037: The specified network resource or device is no longer available”. This kind of error occurs when the power supply to the external device is weak and causes the device to be disconnecting and reconnecting consistently. To fix this problem, you need to check out the potential fixes provided below.

Option 1 – Try to physically check the USB ports

You need to check the USB ports as there could be some ports that are loose or damaged physically which affects the overall performance of the port. You could also try to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

Option 2 – Check the connected cables physically

Aside from the USB ports, you also have to check the physical status of the connected cables because if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 3 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers 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 4 – Try connecting to a slower USB port

If connecting your device to USB 3.0 or 3.1 ports didn’t work, you might want to try connecting it to a slower USB port this time. There are times when the device is not capable of supporting the higher power supply from a USB 3.0 or 3.1 port which is why the weak circuits do not work properly. Thus, try connecting your device to a USB 2.0 port and check if your device is now working.

Option 5 – Try to turn off the Power Saving option

You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.

Option 6 – Try to connect your device to another computer

It is also possible that your computer does not support your device. To check that possibility, you can try connecting your device to a different computer and see if it is working without any issues. If it is, then you need to get another device that’s compatible with your computer.

Option 7 – Try to use a different device

You could also try using a different device and connect it to your computer. This will help you figure out if your device is damaged or not. So if the other device you connected is working just fine, then you might have to replace your device with a new one or consult an expert and have it repaired if possible.

Option 8 – Run the Hardware and Devices Troubleshooters
