Fix Windows Update Error 0x80071a91

As previously announced by Google feature to quickly delete the last 15min of browsing history via one button is rolling out now. For now, only Apple users will be available to use this feature but the Android update is scheduled for later this year, a strange move by Google but it is what it is. For anyone who is unfamiliar with this feature, basically, Google wants a quick way to remove the last 15min of browsing history as a supposedly stated request to make deleting browsing history much easier. Google came up with this idea so you can keep the previous history intact but remove just 15min time frame, no additional explanation was given on why 15 but I presume it is some round number that came up as the middle one with research, read telemetry info. Using quick delete requires being signed into Search with a Google account. Users can access the option by simply tapping on the avatar icon to access the settings then choosing "Delete last 15 minutes."

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

Each you connect time external devices like scanners, printers, and the likes to a Windows 10 computer, the device either pushes the drivers through the USB or any other port, or you are expected to install the drivers through external media. In both cases, the driver will be loaded into the system, allowing you to use the device. However, it doesn’t always go smoothly as you could encounter some errors like the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory ( Code 38 )”. If you encounter such an error in the Device Manager, then this means that a previous version of the device driver is still in memory and that each time the device is used, that previous version is loaded into memory and then unloaded which triggers the “Windows cannot load the Device Driver for this hardware because a previous instance of the Device Driver is still in memory (Code 38)” error. This kind of error occurs if the operating system loads the unwanted driver or if it fails to unload the driver. It could be that there is an obsolete version of the driver that’s still installed in the system or it could also be that you need to update your USB drivers as they could be outdated or the problem could also be due to some third party program that is interfering with the installation. Whatever the cause is, here are some suggestions you can check out to resolve the problem.

Option 1 – Uninstall previously installed drivers and reinstall their latest working version from the manufacturer’s website

The first thing you can do is to uninstall the drivers that are currently installed on your computer and then reinstall their latest working versions from their official sites. This kind of error is commonly encountered while loading drivers for scanners and printers. This is due to the fact that their drivers and software come along with a package which is usually in external media like CD or DVD. So when you install the software package, there’s a possibility that a newer version has been launched by its manufacturer. When that happens, you have to uninstall the previously installed driver package and then download the drivers from the manufacturer’s website and install them.

Option 2 – Run the Hardware and Devices Troubleshooter

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

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 – Restart your computer in a Clean Boot State

If the first three given options didn’t work and you still see the error when you connect external devices, you can try putting your computer in a Clean Boot State and then try connecting them again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to connect the external devices and check if the error is now gone.

You will notice the blurred background on the login screen right away when you start your Windows 10 computer that’s running the v1903 and up. This kind of blurred background is known as “Acrylic Blur Effect on Sign-in Screen”. This new feature delivers a beautiful experience to users by adding more focus to the login screen. However, no matter how nice this feature is and even if it only stays for less than a minute, not all users like it and if you’re one of these users, read on as this post will guide you in disabling the blurred background login screen in your Windows 10 computer. Disabling the blurred background in the login screen can be done in two methods. The first one is via the Registry Editor and the second one is via the Group Policy Editor. Before you proceed, make sure that you are using an admin account and you must create a System Restore point first. Once you have that covered, follow the options provided below.

Option 1 – Disable the Blurred background in the login screen via Registry Editor

• First, tap the Win + R keys to open the Run dialog box and type “Regedit” in the field, and hit Enter to open the Registry Editor.
• After that, navigate to this registry path: KEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• Next, right-click on any empty space in the right pane and create a new DWORD (32 bit) and name it as “DisableAcrylicBackgroundOnLogon”.
• Once you’ve created the DWORD, double click on it and set its value to 1 to disable it and 0 to enable it.
• After you make the necessary changes, restart your computer. You won’t now see the blurred background on the login screen.

Note: No matter what option you select to change the background, it will stay blurred when you click on the login button. At the time of writing, there is no way to disable this feature in the Personalization section so the Registry Editor will have to suffice for now.

Option 2 – Disable the Blurred background in the login screen via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: Computer ConfigurationAdministrative TemplatesSystemLogon
• From there, double click on the “Show clear logon background settings” and since its default value is “Not configured”, set it to “Disabled”. You will see the following description under this setting:
  • “This policy setting disables the acrylic blur effect on the logon background image.”
  • “If you enable this policy, the logon background image shows without blur.”

• Now click on OK and then check the login screen.

Note: If you don’t configure or if you disable this policy, the logon background image adopts the acrylic blur effect. However, if it didn’t work, you have to restart your computer and then check.

If you got an error message saying, “Folder Redirection Failed, Failed to build the list of regular subfolders, Access is Denied” after you configured a new Group Policy Object or GPO which redirects User folders to a new network share or when you click on Reset default location under the Windows File Explorer or Folder Options, then you’ve come to the right place as this post will show you how to resolve this kind of error on your Windows 10 computer. Follow the given options below carefully to fix the “Folder Redirection Failed” error.

Option 1 – Take Ownership of the folder

If you are not able to access the folder could be one of the reasons why you’re getting the “Folder Redirection Failed” error and so you need to take ownership of the folder to resolve the problem. Before you proceed, make sure that your account is an admin account.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 2 – Try to add Authenticated Users or Domain Computers

Make sure that the Folder Redirection group policy removal option is set to “Redirect the folder back to the user profile location when the policy is removed” when using the Folder Redirection. After that, you have to add Authenticated Users group with the “Read” permissions on the Group Policy Objects or GPOs. And if the Domain computers are part of the group of “Authenticated Users”. Note that by default, the “Authenticated Users” have these permissions on any new Group Policy Objects or GPOs. Once again, you have to add just “Read” permissions and not “Apply Group Policy” for “Authenticated Users”. Furthermore, to fix the “Failed to build the list of regular subfolders” errors, here are some options that could help.

Option a – Try to clear disk space

You might have to check if your disk is running out of space because if it is, then it will fail to create a list abruptly. And so you need to free up some disk space. You can either check on the files manually especially if you tend to keep your files at random places in your disk drive.

Option b – Find the Target route

You need to find the target route of the folder and then restore it if you are getting the “Failed to build the list of regular subdirectories” when you try to relocate the folder to the original location.

Option c – Try to change Ownership/Reset Defaults for all the User folders

If the “Failed to build the list of regular subdirectories” error pops up when you are trying to move a large number of files from one location to another, then you need to change the ownership of the folders as pointed out earlier.

If you are using Windows PowerShell and it suddenly throws an error message saying, “File cannot be loaded because running scripts is disabled on this system”, then read on as this post will guide you on how you can fix this issue your Windows 10 computer. This kind of error in PowerShell is most likely due to the fact that your user account does not have the required permissions to execute the script. Although this does not mean that you need to have administrator-level permissions as it could also indicate that you have to be unrestricted to run these types of PowerShell scripts or cmdlets. Thus, to fix the error and carry out the task, you have to set the execution policy to be unrestricted. And to do that, you need to use the steps provided below as a reference. Step 1: To get started, you have to check what policies are set for the individual user groups on your computer by tapping the Win + X key combination or by right-clicking on the Start button and clicking on Windows PowerShell (Admin). You can also search for PowerShell in the Start Search and then right-click on Windows PowerShell and select Run as administrator. Step 2: If a User Account Control or UAC prompt appears, just click Yes to proceed. Once you’ve pulled up Windows PowerShell, type the following command to get the List of Execution Policy for all the scopes on your computer.

Get-ExecutionPolicy –List

Step 3: After you execute the command, it will give you a list of the User Groups as well as their Execution Policy status, and under the Scope column, look for “LocalMachine”. Once you find its Execution Policy you will notice that it’s either set to Undefined or Restricted. Step 4: Now that you’ve determined the Execution Policy, you need to set it to Unrestricted if it is set to Restricted. To do that, you have to enter the following command in the very same PowerShell window.

Set-ExecutionPolicy Unrestricted

Step 5: After you execute the command, you will see a message that asks for various permissions for which you either have to tap Y to say Yes to each one of the messages individually or tap the A key to say Yes to all the messages to once. However, if the command throws another error, you can just force the Execution Policy to change by executing the following command.

Set-ExecutionPolicy Unrestricted -Force

Step 6: Once you’re done, it will finally set the Execution Policy for the Windows PowerShell scripts as well as cmdlets to be Unrestricted and fix the “File cannot be loaded because running scripts is disabled on this system” error.

If you suddenly get a message telling you that “Your Windows license will expire soon, You need to activate Windows in Settings” on your Windows 10 computer but you know that your Windows 10 is already activated. Worry not for this post will help you get rid of that error message right away. Before you get started, make sure that you have the Windows product key with you. If you don’t, you can get it by running the following command in an elevated Command Prompt:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Take note of the product key and then proceed to the options given below.

Option 1 – Try activating Windows 10 again or use another product key

• If you’re sure that you have the correct product key, click the Go to the Settings button.
• After that, click the Activate button once again.
• If you have another license key, you can also use that as well, just simply click on the Change product key.
• Then enter the new product key and click on Activate. That should fix the problem, if it doesn’t, refer to the next option below.

Option 2 – Try to reset the licensing status

• Click the Start button and then type “cmd” in the Search box and then tap Ctrl + Shift + Enter to open an elevated Command Prompt.
• Next, type the “slmgr –rearm” and hit Enter to reset the licensing status.
• Restart your computer and check if the error is now gone or not.

Option 3 – Try uninstalling the product key and re-enter it once more.

• The first thing you have to do to uninstall the product key is to know the Activation ID of your Windows installation. To do so, open an elevated Command Prompt and type this command, and hit Enter – vbs /dlv
• After you enter the command, you should see the licensing status and Activation ID. And to get all the Activation IDs of all the installed Windows versions, key in this command and hit Enter – vbs /dlv all

Note: The “/dlv” parameter will give you the license information for the installed operating system.

• After you enter the second command, you should see a Windows Script Host window with all the Windows licensing and activation status. Take note of the Activation ID.
• Next, in the same elevated Command Prompt, type this command – slmgr /upk <Activation ID>

Note: In the third given command, “/upk” stands for “uninstall product key”. This parameter uninstalls the product key of the current Windows edition.

• Restart your PC. After that, your computer will be in an unlicensed state so you need to re-enter the product key again.

Option 4 – Try rebuilding the Tokens.dat file.

The issue might be caused by a corrupted Tokens.dat file. The Tokens.dat file is a digitally signed file that stores most of the Windows Activation files so if it is corrupted then no wonder you’re having activation issues. To rebuild the Tokens.dat file, refer to these steps:

• From the WinX Menu, open an elevated Command Prompt.
• After opening Command Prompt, you need to type each one of the following commands and after you type each command, hit Enter.
  • net stop sppsvc
  • cd %windir%ServiceProfilesLocalServiceAppDataLocalMicrosoftWSLicense
  • ren tokens.dat tokens.bar
  • net start sppsvc
  • exe %windir%system32slmgr.vbs /rilc
• Now restart your computer.

Option 5 – Try running the Windows 10 Activation Troubleshooter

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

Option 6 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.
