Fix Update Error 0x800705B3 in Windows

The issue with the abrupt system reboots to force Windows 10 updates on a computer has been lessened with Active Hours. This feature keeps a record of the hours during which a system remains active and prevents the installation of updates during such hours. For example, when a system restart is needed to complete the installation of an update, Active Hours delays the update and allows you to finish what you’re doing on your computer. Thus, if you haven’t heard of this feature, then now is the time you do, read this post to configure and use Active Hours in your Windows 10 computer. There are three ways you can configure Active Hours. The first one is for general users, whereas the rest of the two methods are for users who knows their way about the Windows Registry and Group Policy. To get started, refer to every given option below.

Option 1 – Configure Active Hours via Windows 10 Settings

• Go to Settings > Update & Security. From there, click on the “Change active hours” option under the Windows Update section.
• Next, you can select a time (“Start time” and “End time”) during which the restart can occur.
• After that, click on the Save button and exit.

Note: Keep in mind that the values you’ve entered indicate the hours during which your system is in use, namely, ACTIVE. It is important for your active hour’s interval period and it can be anything between 1 and 18 hours since you can’t go beyond 18 hours. In addition, there is no option to configure different active hours on different days and you can’t specify different active hours for weekends and weekdays as well. On the other hand, Windows 10 also offer users an option to override Active Hours. All you have to do is go to Settings > Update & Security > Windows Update > Restart Options. From there, you can choose a custom restart time when your computer will restart to install the updates but this is only a one-time setting.

Option 2 – Configure Active Hours via Registry Editor

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter or click OK to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsUpdateUXSettings
• In the given registry path, you can choose to change “ActiveHoursStart” and “ActiveHoursEnd”.

Note: There are no extra settings available in the Registry Editor but you can change the remote computer’s Active hours settings using the Registry Editor.

Option 3 – Configure Active Hours via Group Policy

Note that this option is available for the Windows 10 Pro and Educational or Enterprise versions. It is mostly used by computers in Business or through remote access. To get started, follow these steps:

• Tap the Win + R keys to launch Run and type “gpedit.msc” in the field and tap Enter or click OK to open the Group Policy Editor.
• Next, navigate to this group policy setting: Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Windows Updates.
• From there, look for a policy labeled “Turn off auto-restart for updates during active hours” and double click on it. This will open a new window.
• Click on the Enabled radio button to enable Active Hours. You also have the option to choose active hours just like in the first given option above. It works just fine except when the following policies don’t override:
  • No Auto-restart with logged-on users for scheduled automatic updates installations.
  • Always automatically restart at the scheduled time.

• Since Group Policy allows you to reduce the range of active hours, you can configure it if you want it to be less than 18 hours. Just find the policy setting labeled “Specify Active hours range for auto -restarts. The minimum is 8 hours”.
• After you set the Active Hours, click the Apply and OK buttons to save the changes made.

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:

• 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.

And now that you’ve successfully configured the FTP Server, the next thing you have to do is to allow connections from and to the FTP server. Refer to the next step below. Step 2: Configure the Windows Firewall for FTP connections to pass-through

• In the Start Search, type “Allow an app or feature through Windows Firewall” and click on the related search result which will open a window with all the settings.
• From there, click on the Change Settings button. This will display a list where you have to mark all the checkboxes for the FTP server to enable them in both the Private and Public configurations.
• After that, click OK. This will allow you access to the FTP server on your local network.

Option 3 – Try to run the DISM tool

If the first two options didn’t work, then running the Deployment Imaging and Servicing Management might. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to stop the Runtime Broker process

The RuntimeBroker.exe or the Runtime Broker process is the one that monitors access to Windows APIs to make sure that the apps do not violate the core security of Windows. This process usually leaves a very small footprint. However, there are times when it consumes more resources than it’s supposed to and does not release memory after the work is done that results in a memory leak. As a result, it affects NTOSKRNL.exe which is why you have to stop the Runtime Broker process. To do so, refer to these steps:

• Tap the Ctrl + Shift + Esc to open the Task Manager.
• After opening Task Manager, go to the Processes tab and look for the Runtime Broker process.
• Once you find it, check if it is using more than 15% of your memory. If it is, then you most likely have an issue with an app installed on your computer.
• Select the Runtime Broker process and right-click on it and then click on the End Task option to end its process.

Option 5 – Try to run the Performance Troubleshooter

• Tap the Win + R keys to open the Run dialog box.

So, you just made some popcorns, dimmed light, relaxed in from of the TV, pressed play on your application and Blu-ray drive can not read your movie. Your movie night failed sadly, but there is hope and in this article, we are going to explore and offer you solutions on what to do when something like this happens so you do not miss another movie night and some hard-earned relaxation. Please note that in this article we are assuming that you are using a Blu-ray player on your PC, so some of the solutions presented are meant only for this case. So the first thing that you are supposed to do is to check the disc itself. You can turn the disc around and visually check the disc for fingerprints and scratches which can be fatal for disc playing, alternatively, you can try to play the same disc on another device and if it fails there also it is not the disc, it is your drive. So if it is no issue with the disc let's see that seems to be a problem with the drive. The common thing that could stop disc reading are cables, check all connections and cables in the back of your device to be sure that everything is plugged in correctly and nicely. After checking cables if the issue persists lens cleaning is the next step. Over time lens from the Blu-ray, the device becomes dirty and dust accumulates on it, there are special cleaning discs on market made especially for this purpose, to clean the dirty lens of optical devices. If you have one put it in and clean your lens. After lens cleaning with a specialty disc, a good idea would be to use compressed air in a can to reduce the dust inside so no excess dust will accumulate quickly again on the lens itself.

So the device is cleaned and checked and still no disc playing?

In case you don’t know, Driver Verifier is a built-in utility in the Windows 10 operating system. It is the one that ensures the integrity of all the drivers in the system. It can detect any suspicious behaviors of the drivers and if it finds the driver signature of some suspicious activity during runtime, it stops the suspected action by triggering a BSOD or Blue Screen of Death error and one of these Stop errors is the DRIVER_VERIFIER_DMA_VIOLATION error. When you encounter such an error, you will see the following message on your screen:

“Your PC ran into a problem that it couldn’t handle, and now it needs to restart. If you’d like to know more, you can search online later for this error: DRIVER_VERIFIER_DMA_VIOLATION”

There are several ways you can fix this error. You can try to disable the Driver Verifier or run the Hardware troubleshooter. You could also try to update, roll back or uninstall the drivers on your computer. For more details, refer to each one of the options provided below.

Option 1 – Try to disable the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues.

• Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
• After that, select the option “Create custom settings”.
• Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
• Next, select the option “Select driver names from a list” option.
• Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
• Then click on the Finish button.
• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
• Open the Command Prompt as admin again and run this command – verifier /reset
• The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 2 – Try to reinstall or update device drivers of recently installed hardware

If the first few options didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them 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, restart your computer. It will just reinstall the device drivers automatically.

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 3 – Try running the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like DRIVER_VERIFIER_DMA_VIOLATION. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Note: You could also run the Hardware and Devices troubleshooter as it could also help in fixing the DRIVER_VERIFIER_DMA_VIOLATION error.

Option 4 – Try running Microsoft’s online Blue Screen Troubleshooter

If running the built-in Blue Screen Troubleshooter didn’t work, you can also try running Microsoft’s online Blue Screen Troubleshooter. All you have to do is go to Microsoft’s website and from there, you will see a simple wizard that will walk you through the troubleshooting process.
