There are instances when the Windows 10 installation needs interaction before it reaches the file process. And so if you suddenly encounter the Windows Update Installation Failure 0x80240020 error under the Windows Update History, then you need to get it fixed. When you encounter this kind of Windows Update Error, you will see an error message that says, “The operation did not complete because there is no logged-on interactive user”. This error also indicates the “WU_E_NO_INTERACTIVE_USER” code. To resolve this issue, in this post we’ll walk you through a couple of steps but before you get started, know that you don’t have to run any troubleshooter or delete any file just to fix this error since all you have to do is enable one option that can automatically login with your account and complete the installation for you. With that said, just make sure to only try running Windows Update once you’re told to do so. There are two ways you can enable the option that could resolve the Windows Update Installation Failure 0x80240020 error. One is via Settings while the second one is via Registry Editor.

Option 1 – via Settings

Step 1: Go to Settings > Accounts > Sign-in Options. Step 2: From there, toggle on the “Use my sign-in info to automatically finish setting up my device and reopen my apps after an update or restart” option. Step 3: After that, it will make sure that the interaction part is removed from the Windows Update process. Note: If your device is joined in a domain or if some work or email policies are applied to your device by your company or organization, then you wouldn’t be able to see this option in Settings and that’s where the Registry Editor comes in. Just make sure that you’re logged in as an administrator and that you create a System Restore Point first since registry hacks are sensitive and could highly impact how your computer behaves or functions. Once you have that covered, follow the steps below.

Option 2 – via Registry Editor

Step 1: In the Start search, type “Regedit” and hit Enter to open the Registry Editor. Step 2: Navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdateOSUpgrade

Note: If the above-given registry key does not exist, you can simply create it. All you have to do is right-click on the WindowsUpdate key and then select the New Key option and type “OSUpgrade” as its name. Afterward, create a new DWORD (32-bit) Value and name it “AllowOSUpgrade” and set its value to 0x00000001. Step 3: Restart your computer and check if the error is now fixed. And then try to update your Windows 10 computer again and while you’re at it, make sure that you’re around your computer to interact with the prompts needed to complete the installation process.

Upgrading your computer from Windows 7 or Windows 8 to Windows 10 or even upgrading Windows 10 to a new version is not that simple. The setup initially checks for all the drivers and other software utilities installed on your computer and verifies and blockages or upgrade or upgrade blocks with respect to any of those drivers or any of those software utilities regardless if you use the Windows 10 ISO or the Windows 10 Upgrade Assistant. One of these common errors, when you upgrade or update your computer, is the “The Display is not compatible with Windows 10” error. This kind of Windows Upgrade error is related to the compatibility of the Graphics Driver installed in your computer. But worry not for this post will guide you in fixing this problem. The “The display is not compatible with Windows 10” error has the same workarounds as the following errors:

• These devices aren’t fully compatible with Windows 10.
• The display is not compatible with Windows 10. Check with the manufacturer for support.
• The display manufacturer hasn’t made your display compatible with Windows 10. Check with the manufacturer for support.

To resolve this Windows Upgrade error, here are some suggestions that could help:

Option 1 – Check for incompatible drivers in your computer

• Open the Device Manager from the WinX Menu.
• Then expand the list for Display Adapters.
• Next, right-click on the NVIDIA Graphics Card list and select Enable.
• After that, right-click on it again and click on the “Update Driver Software…” option.
• After doing so, a new window will appear and from there, click on the “Search automatically for updated driver software” option.
• Then check if Windows is now able to detect your Graphics Card as well as the latest driver for it. If not, proceed to the next step.
• Right-click on the driver again and click on the “Update Driver Software…” option.
• Now click on the Browse my computer for driver software option and then click on Let me pick from a list of device drivers on my computer.
• Afterward, select a compatible driver for your computer named NVIDIA Graphics Card and then proceed.
• Wait for the whole process to be completed and restart your computer to successfully apply the changes made.

Option 2 – Get the latest version of Graphics drivers from the manufacturer’s website

In case you don’t know the manufacturer of the Graphics Processing Unit or GPU of your computer, you need to check first. They’re usually NVIDIA, Intel, or AMD. So if your computer’s Graphics Processing Unit is manufactured by NVIDIA, you need to get the latest version from their official website.

Option 3 – Try to install the latest Graphics driver in Compatibility Mode

If you’re not able to install the Graphics drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• You also have the option to change the DPI settings and see if that helps. Then click the Apply and OK buttons.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

One of the most useful built-in tools in Windows 10 is the Check Disk or CHKDSK utility. It is the one that maintains the integrity of the disk that’s connected to a computer which can be launched using the GUI or graphical user interface and using the command line. There are a lot of things that warrant the running of this built-in utility and one of these things is the readability of the disk. Recently, a number of users reported that they encountered an error when they tried to run the CHKDSK utility – the error states, “Cannot open volume for direct access”. This kind of error in CHKDSK appears each time the command line is launched according to the affected users. As per the users who encountered this issue, they receive the following error messages when they tried running a ChkDsk command:

“C:WINDOWSsystem32>chkdsk /f g: Cannot open volume for direct access. C:WINDOWSsystem32>chkdsk /f f: The type of the file system is NTFS. Volume label is 0529357401.”

To fix the “Cannot open volume for direct user access” error, here are some suggestions that might help. Follow them carefully.

Option 1 – Try running the CHKDSK utility on Boot

On the other hand, you can also try to run the CHKDSK utility on Boot so you can fix the error and recover any damaged segments of the drive.

• Open an elevated Command Prompt and enter this command: chkdsk /x /f /r
• After that, you will a message that says, “Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)”
• Type Y and tap Enter to schedule a CHKDSK scan once your computer reboots next time.

Option 2 – Try to run the Primary Hard Disk Self Test

The next thing you can do to fix the problem is to run the Primary Hard Disk Self Test by following the steps below.

• You need to boot your computer into the BIOS first.
• After that, go to the Diagnostics tab and select the “Primary Hard Disk Self Test” option. Note that it may be different depending on the motherboard with different manufacturers but they should imply the same thing.
• Now, wait until the test is completed, and then boot your computer normally.

Option 3 – Try to check the hard drive’s health

The next thing you can do to resolve the issue is to check the health of your hard drive using the WMIC utility in the Windows Command Prompt. This utility will check if your hard drive has any problems which resulted in the “Cannot open volume for direct user access” error.

Option 4 – Try to disable various restrictions on your hard drive

You might also want to disable the various restrictions on your hard drive since it is possible that it is encrypted or restricted which explains why you are unable to perform any operations in it and throws the “Cannot open volume for direct user access” error instead. For instance, if you have BitLocker, you can try to disable it and see if it fixes the error or not.

Option 5 – Try to uninstall or disable the Drive Locking feature on your hard drive

You could also look for any Drive Locking feature on your hard drive that tricks disk changes as it might be the root cause of the problem. Thus, if you find one, you need to either uninstall or disable it and then execute a check disk command to resolve the problem.

Option 6 – Try to disable the application service

Disabling the application service can also help you fix the problem. How? Refer to these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and then hit Enter to open the Services Manager.
• Next, scroll down among the list of services and look for the service related to the security software or disk checker software.
• Once you find it, right-click on that service and select Properties.
• After that, change its Startup type to Disabled and click on the OK and Apply buttons to save the changes made.
• Now restart your computer and don’t forget to enable the service back once the disk check is completed.

Option 7 – Try to use Repair Volume via Windows PowerShell

You could also try to use the Repair Volume using Windows PowerShell. All you have to do is open PowerShell as admin and type the “repair-volume -drive letter <DRIVE LETTER>” command and then tap Enter to run Repair Volume. This should resolve the error.

Many Linux users if not all of them can run their distros from a USB drive but did you know you can run Windows 10 from a USB drive as well? Microsoft has introduced all the way back to Windows 8 one feature called Windows To Go and it kept it in Windows 8.1 and in Windows 10 as well. This feature is intended as a convenient way for workers to carry their corporate environments with them, but having your own copy of Windows on a thumb drive could be handy for backup purposes, too, or if you frequently use public machines that lack your preferences/applications or that have a restricted OS.

What you will need?

In order to actually make Windows 10 run from a USB drive you will need the following things:

1. USB drive with a minimum size of 20GB
2. Working computer with Windows 10 running on it
3. Rufus or another ISO to UBS tool, get Rufus here: https://rufus.ie/en_US/
4. Windows 10 ISO file

Making Windows 10 UBS drive

Install Rufus on your Windows 10 and run it. Stick USB in PC and open Rufus. On the screen that follows choose your Windows 10 ISO image and under Image options choose Windows To Go. Click on ready and you are finished, that’s it. After Rufus finishes you have now fully working Windows 10 bootable drive which you can use on another PC for whatever reason.

As you know, Windows 10 comes with a pre-packed feature that allows you to rotate the screen at different angles, and to facilitate this feature, there are keyboard shortcuts you can use as well. However, from time to time, no matter how useful this feature is, users still experience a handful of issues. One of which is that they suddenly find their screen rotated or Upside Down even when they didn’t do a thing or adjust the setting. You may have pressed the shortcut on the keyboard by accident or some other program changed the setting on your computer without your permission – whichever the case is, this post will show you what you can do to fix the upside-down screen on your Windows 10 PC using the options laid out below.

Option 1 – Try using hotkeys

As mentioned earlier, Windows have hotkeys in the UI that changes the orientation of the display. So the first thing you need to do is to make sure that these hotkeys are enabled and if they are, you can use the keyboard shortcut to adjust the orientation of your screen.

• Right-click on an empty part of your Desktop and then select the Graphic options.
• Next, select “Hot Keys” > “Enable”. After verifying that the hotkeys are enabled, you can tap the Ctrl + Alt + Up arrow keys to change your computer screen’s orientation.
• Alternatively, you can also tap the Ctrl + Alt + Right or Left or Down arrow keys to change the direction the other way.

Option 2 – Try using the Graphics Properties

You will probably see the “Graphics Properties” option if you use the Intel HD Graphics every time you click on your Desktop. Note that this option has all the graphics driver properties and helps you in changing the configurations as well as control several options like refresh rate, resolution, color-depth and many more. You have to navigate to these options to see if the orientation is changed in these properties. To do so, follow the steps below.

• Right-click on any empty space on your Desktop and then select Graphics Properties or Intel Graphics Settings.
• After that, select Display from the list of sub-options that appears.
• From there, you will see the rotation of the screen under the “Display settings” option where you have to make sure that the slider is set to “0”.
• Click the Apply button to save the changes made and then click on Exit. The orientation of your screen should automatically change.

Option 3 – Try using the Windows Display Settings

Since the Windows Settings have a section where you can manage the display settings of your computer, you can use them to help control the resolution of your PC’s display without any trouble. There is a possibility that the settings are changed there so that’s probably why your screen is turned upside down all of a sudden.

• Tap the Win + S keys to open search and then type in “settings” in the field and then hit Enter to open Settings.
• After opening Settings, click on System and then on Display using the left navigation bar and then scroll to the end and select the Advanced display settings.
• Next, click on the Display adapter properties and click on Intel HD Graphics control panel.
• Now change the rotation to 0 Degrees. Afterward, the display should revert back to its original form automatically.

Option 4 – Check your monitor’s physical controls

There are monitors that have buttons in them that allows users to shift the rotation of the screen to 90 degrees. It could be that your monitor has these buttons without you knowing and you suddenly pressed them by mistake which caused your screen to rotate. Thus, you have to check your monitor for any physical buttons on the side and if you see a menu, navigate to its options and check if there are screen rotation options. To make it easier for you, you can simply search your monitor’s model online and see if these buttons exist. You could also go over your monitor’s manual if you still have it as it contains details with regards to screen rotation.

Option 5 – Update your Graphics drivers

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
