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.

In every task carried out in the Windows 10 operating system, some of them don’t go smoothly and it could encounter a couple of errors along the way. One of these errors you could encounter is the Windows Update error code 0x8007000e. This particular error was reported to occur a lot when downloading and installing a Feature update via Windows Updates. And recently, it has been reported to occur a couple of times for the Windows 10 1903 May 2019 update.

Whatever the cause is, troubleshooting this problem shouldn’t be hard as this post will give you some potential fixes you can check out. To fix this error, here are some options you need to consider:

Option 1 – Clear up temporary or junk files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
  • Windows Upgrade Log Files
  • System created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.

Option 2 – Reset the Windows Update components

If by any chance that the second option didn’t work, resetting the Windows Update components could also help you resolve the problem. How? Refer to the following steps:

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below and don’t forget to hit Enter after you type one command after the other.
  • ren C:/Windows/SoftwareDistribution/SoftwareDistribution.old
  • ren C:/Windows/System32/catroot2/Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 3 – Try configuring the Windows Update-related Services

• Tap the Win + R keys to open the Run dialog box.
• Then type “cmd” in the field and tap Enter to open an elevated Command Prompt.
• Next, execute the following commands. Note that you have to type and enter each the command one after the other.
  • SC config wuauserv start= auto
  • SC config bits start= auto
  • SC config cryptsvc start= auto
  • SC config trustedinstaller start= auto

After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Try to use the Media Creation tool

The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation tool to make a bootable drive.

• After making the bootable drive, you need to plug it in your computer and then reboot.
• Next, tap the F10 or Esc key to open the boot options.
• Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.

There are times when the WMI Repository gets corrupted which results in the Provider Load Failure. To resolve this issue, you need to repair or rebuild the WMI Repository in your Windows 10 computer. In this post, you will be guided on how exactly you can do that. In case you don’t know, the WMI which stands for Windows Management Instrumentation is a set of specifications from Microsoft to consolidate the management of devices and applications in a network. The WMI is a database that stores meta-information and definitions for WMI classes. Using only these, the conditions of the systems can be known. You can find the WMI Repository in %windir%System32WbemRepository. It provides end-users with the status of the local or remote computer system. Keep in mind that you must not use this on the Server 2012 Cluster machine. Although there are command-line tools that can fix or restore the Windows Management Instrumentation repository. However, Microsoft suggests that it’s better if you verify if there is corruption. Here are a list of errors as well as permission issues you might encounter:

• Unable to connect to root default or rootcimv2 namespaces. It fails with the error code “0x80041002” pointing to “WBEM_E_NOT_FOUND.”
• 0x80041010 WBEM_E_INVALID_CLASS
• When you open Computer Management and Right Click on Computer Management (Local) and select Properties, you get the following error: “ WMI: Not Found” or it hangs trying to connect
• Trying to use wbemtest , and it hangs
• Schemas/Objects missing
• Strange connection/operation errors (0x8007054e)

To verify if there is corruption, you can try running the following command in an elevated Command Prompt:

winmgmt /verifyrepository

 After you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue. If not, then something else is causing the problem. Since you are certain that corruption exists in the WMI repository, then here are some suggestions you need to check out to repair or rebuild the WMI repository.

Option 1 – Try to reset WMI Repository

• Type “command prompt” in the Start Search and right-click on Command Prompt from the search results and then select “Run as administrator”.
• After opening Command Prompt with admin privileges, type and enter this command: winmmgmt /salvagerepository

The command you entered is used when the winmmgmt command performs a consistency check. So if an inconsistency is detected, it will rebuild the repository.

• Next, execute this command to see if the WMI repository now comes back as consistent: winmgmt /verifyrepository

This command will perform a consistency check on the WMI repository.

• If it states that the WMI repository is not consistent, then you need to type and enter this command: winmgmt /resetrepository

This command is used to reset the repository to its initial state when the operating system was first installed.

Option 2 – Try to force recover the WMI Repository

The WMI Repository comes with a built-in self-recovery process so when the WMI service restarts or detects any corruption, it will automatically trigger the self-recovery procedure. This can happen in two ways:

• AutoRestore: This will use the backup images if the Volume Shadow copy or VSS backup is turned on.
• AutoRecovery: The rebuilding process will generate fresh images of the WMI repository based on the registered MOFs. The MOFs are available in the registry located at HKLMSoftwareMicrosoftWBEMCIMOM: Autorecover MOFs

Note: Autorecover MOFs is a key so double click on it to check its value. On the other hand, if the self-recovery procedure does not work, you can try to use the force-recovery process instead. How? Refer to these steps:

• First, you need to check the reg key value is empty or not under this registry path: HKLMSoftwareMicrosoftWBEMCIMOMAutorecover MOFs
• If the reg key value is empty, you have to copy-paste the reg key value from another computer. Just make sure that it’s from the System which is equivalent to the computer in question.
• Next, type and enter this command: Winmgmt /resetrepository
• After you enter the command, if you get an error that says, “WMI repository reset failed. Error code:0x8007041B. Facility: Win32”, then you have to stop all the Dependency Services on the WMI service by running the following commands:
  • net stop winmgmt /y
  • Winmgmt /resetrepository

This should fix the problem.
