File Transfer Protocol Server, also known as FTP Server, is a private or public service that can host files that can be accessed both locally and globally. It is a quick, flexible and seamless service that allows you to store any kind of files depending on the total size of the server. If you’ve always found an FTP server useful, then the good thing is you can now create your FTP server since Windows 10 now allows it. You can host this server locally and later on make it globally available via the internet. So if you are planning to set up an FTP server on your Windows 10 computer, read on as this post will guide you on how to do so.

To set up the FTP server, you need to configure it first and then configure the Windows Firewall for the connections to go through. For more details, refer to the following steps:

Step 1: You need to configure the FTP server on Windows 10.

• In the Search box, type in “Turn Windows Features On or Off” to search for it.
• Then click on the appropriate result which will open a mini window.
• From this mini window, scroll down to the list and expand “Internet Information Services where you have to expand the FTP Server section.
• Next, select all the checkboxes to enable all the entries under FTP Server and then click the OK button to apply the changes made.
• And now, since your computer is now allowed to host an FTP server, you need to configure it. To do so, type “Internet Information Services (IIS) Manager” in the Search box and click on the appropriate entry.
• Next, right-click on Sites under the navigation bar of Connections and select Add FTP Site. This will open a new window where you have to input some information about your FTP hosting.
• Now enter the details and click on Next.
• Upon clicking Next, you will be prompted to give some authentication details. Enter the following details in the screenshot below.
• Now click on Finish. After that, you will get an FTP Server being hosted on your Windows 10 PC.

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

In case you don’t know, Groove Music is due to retire its OneDrive streaming service this month. Despite that being the case, there is actually a workaround you can try to still continue enjoying music streaming. The app also allows you to play your own local files and if required, you can also modify or tailor the experience with new features – for instance, Groove Music brings an Equalizer to the settings of the app. As the name suggests, the equalizer allows you to tweak frequency responses to your liking. On top of being able to tweak individual bands, the equalizer supports few pre-set settings to enable quick changes. This post will guide you on the process of accessing and using the equalizer in the Groove Music app. To get started, refer to the instructions provided below. Step 1: You need to make sure that you are running the latest version of the Groove Music app or version 10.18011.1211.0 or higher in order to use the equalizer in Groove Music. If needed, you can check the version number from Windows Store. Step 2: Open Windows Store and then click on the ellipses icon and select the Downloads and Updates option. Step 3: Next, search for Groove Music and check its version number. Step 4: Now that you’ve verified the version number of Groove Music, you need to open the equalizer setting. It is enabled by default and to access it, click on the gear icon for Settings and select equalizer under the Playback settings. Step 5: After that, the Equalizer window will pop up. It is where you can configure the equalizer settings using the drop-down menu. Here are the following presets you can choose from:

• Flat
• Treble Boost
• Bass Boost
• Headphones
• Laptop
• Portable speakers
• Home Stereo
• TV
• Car
• Custom

Step 6: Drag the dots upwards or downwards to set your own preferences, as needed. Note: The only downside to this setting is that there is no shortcut available for quick access as you have to navigate through the Settings section manually to access it and change the preset configurations. In addition, the Groove Music app also works on the mobile version of Windows 10.

It seems that Microsoft is going to offer subscription and sales of individual office applications in the Windows Store. The office package will still be available as a package but for the first time, we will get single applications as standalone ones available for purchase. This is a very interesting decision by Microsoft and I fully support it, this time users will be able to pay less and to choose only applications that they need instead of paying for the whole package and not using it.

A PC that turns on by itself every so often can get quite annoying. Many users have faced this problem countless times. There are lots of possible reasons why your Windows 10 PC turns on by itself, wakes up from sleep, standby, or even when it’s shut down. To find out what exactly woke your computer, simply open Command Prompt as admin and type the following command:

powercfg –lastwake

Once you enter the command given above, it will show you the last device that woke your PC up. After that, you need to type in the next command:

powercfg –devicequery wake_armed

After entering the command, it will show you a list of all the devices that could wake your PC up. The goal in running these commands is to understand the reason what’s really causing your PC to turn on and see the reason is on the hardware level or not. Here are a couple of options you can try if your Windows 10 PC turns on by itself.

Option 1 – Try disabling Fast Startup

As you know, Windows 10 comes with a mode called Fast Startup which does not turn off the computer in the usual manner. This mode keeps your computer in a mixed state so that when you turn it on again, it will be a lot faster. However, as useful as this feature appear to be, some security experts find this an issue, for numerous reasons – for one, it can turn on your Windows 10 PC by itself. Thus, you need to disable this feature to fix the problem.

Option 2 – You need to stop the Task Scheduler from waking up your computer

There are times when the issue has something more to do with the software than hardware. It could be that you are using a Scheduled Task to get some work done on your computer at a particular time of the day or many times a day. That’s why if you really are using Task Scheduler, you need to change the Power settings of Windows to make sure that it ignores those tasks rather than deleting them instead when your computer is either on Hybrid or Standby mode.

• Open the Power Options and then click on “Change Plan Settings”.
• After that, make sure to choose the correct power plan and then select the “Change advanced power settings” option.
• Next, look for the Sleep tree and expand it to view the “Allow Wake Timers” option and then disable it. Disabling this option will make sure that none of the program that could wake your PC up when it’s either on shutdown or sleep mode. However, this only applies to laptops.

Option 3 – Try to disable Automatic Restart

There are instances when the computer crashes and the system restarts itself. This is actually by design – when your computer has been left on standby, the computer will restart and if the program repeats, it will keep on waking your PC up.

• In the Search bar, type in “system”.
• Once it appears from the search results, click on it.
• Next, select Advanced system settings on the left side and then go to the Advanced tab.
• From there, click on Settings under Startup and Recovery.
• Then unmark “Automatically Restart” and click on OK.

Option 4 – Adjust the Power Management option of both the Keyboard and Mouse

As you know, two of the culprits in waking your PC up are the keyboard and the mouse. If they’re slightly moved or hit, your PC turns on. To prevent these two from waking your computer up, you need to make some adjustments to their power management option since they have one. You can disable this option to ensure that they won’t wake your PC up unless you really want it to.

• Tap the Win + X keys and then tap M to open the Device Manager and list all the hardware on your computer. From there, select your keyboard or mouse.
• Next, right-click and then go to Properties and go to the Power Management tab.
• In this tab, uncheck the “Allow this device to wake the computer” box.

Note: Aside from the keyboard and mouse, if you are also using any gaming rig to play games on your computer, then you might have to disable their power options as well as they could also wake your computer. Just make sure that either the keyboard or the mouse has the ability to wake your computer up at the very least as it can be quite inconvenient to tap the Power button every time you want to turn on your computer.

Option 5 – Modify Wake On Lan

The Wake On Lan feature can bring back your computer online if it is connected to a network. This feature is useful especially when a computer wants to communicate or to send data or files to a network computer which should come online only when it’s requested. Wake On Lan is built into the hardware, i.e. network adapter so it is one of the possible reasons why your PC turns on by itself.

• Tap the Win + x keys then hit M to open the Device Manager and then under the Network adapters, look for the one that was listed above. Take note that you must not change anything with the ones that are listed as Miniport.
• Next, right-click and select Properties and then go to Power management and from there, uncheck the “Allow this device to wake up the computer” option. This will ensure that no PC on the network can ever wake your computer up.

Option 6 – Prevent any scheduled Windows Update and Automatic maintenance

It is also possible that the Windows Update has restarted your PC to complete the update. This depends on your active hours or a predefined schedule. AS you know Windows has a built-in Automatic Maintenance mode which wakes the computer up at the scheduled time and performs the system update. This could be one of the possible reasons why your computer turns on by itself. so to prevent any scheduled updates and maintenance, you can simply change the time for Automatic maintenance. How? Follow these steps:

• Open Settings then go to Windows Update and Security >Windows Update and select Active Hours.
• After that, type in “Automatic maintenance” in the search bar to change the time for Automatic maintenance.
• From there, you can adjust the timing or just uncheck the “Allow scheduled maintenance to wake up my computer at the scheduled time” box.

A lot of Windows 10 users have reported recently that their computers are frequently crashing with a Blue Screen error with an error code “VIDEO_DXGKRNL_FATAL_ERROR”. This kind of Stop error appears not so often and its bug check value of 0x00000113 is an indication that there is some violation in the Microsoft DirectX graphics kernel subsystem. This error also occurs when there is a corrupted driver that interferes with the GPU’s normal functionality. According to some security experts, this kind of error is reported to only occur in Windows 10 PCs. Users started getting this error right after a large Windows Update. The cause of this error might have something to do with a violation in the DirectX graphics kernel subsystem where there could be a bad DirectX install or some corrupted Dynamic Link Library or DLL. Aside from that, the error might also be caused by the Nvidia driver which might have crashed or it could also be that there is an intermittent power supply. Moreover, an outdated BIOS as well as a third-party security program might be the ones behind this Blue Screen error. Whichever the case may be, you need to fix the VIDEO_DXGKRNL_FATAL_ERROR BSOD error by following the instructions given below carefully.

Option 1 – Try checking if the NVIDIA graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the NVIDIA graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the NVIDIA graphics card is enabled or not. To do so, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• After opening the Device Manager, look for the Nvidia graphics card option among the list of device drivers. Once you found it, check if it is enabled or not. If it’s not enabled, you should see a gray arrow pointing downwards. Right-click on the card and select Enabled.
• Next, right-click on the graphics card once more and click on the Update Driver Software option and then click on the “Search automatically for updated driver software” option.

Option 2 – Update or uninstall third-party security program

As mentioned, the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen error might be caused by a third-party security program that’s installed on your computer. So you have to either update it or uninstall it to resolve the issue.

Option 3 – Check the power supply for any inconsistency

The Blue Screen error might also be caused by an intermittent power supply. If there is any intermittent changes between the main supply and the battery power, it might lead to bad contact on your supply to the charger and thus, causes the VIDEO_DXGKRNL_FATAL_ERROR Stop error to appear. So to check if this scenario is applicable to you, you have to monitor your computer for any frequent changes between the power supply and the battery power. If you see that the supply is displaying power On and Off, see if the same goes when the power supply is disconnected. However, if it does not occur, you might have to purchase a new power adapter cable and replace the one that you have right now.

Option 4 – Reinstall the Graphics card drivers

• Tap Win + R to open Run then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, look for the Display adapters and uninstall each one of the graphics card drivers by right-clicking on them and selecting the Uninstall device option.
• After uninstalling the graphics card drivers, close the Device Manager and tap Win + R to open Run once again.
• After that, type “appwiz.cpl” in the field and hit Enter to open Programs & Features in the Control Panel.
• Next, look for any program that’s related to your GPU manufacturers like Nvidia, AMD, or Intel. Right-click on any GPU-related entry and click on Uninstall to uninstall them and then follow the next on-screen instructions that appear afterward.
• Now restart your computer.
• Once your computer has restarted, go to the GPU manufacturer’s website and download the latest driver version for your graphics card model and then install it.
• Restart your computer once again. That should fix the problem.

Option 5 – Try checking if there are any BIOS updates available for your PC

Updating the BIOS may help you resolve the BSOD error. You can just go to the OEM’s website as they offer utility software that can download BIOS firmware and update it without any problem. BIOS updates usually offer enhancements and fixes to some issues like this one.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen of Death error. 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.
