Fix Windows Update Error 0x80071a91

Recently, a number of users reported seeing plain white icons on their “.docx” files instead of the Word icon. This kind of issue is mostly caused by a conflict with the default program settings in Windows which is why you may not see any Microsoft Word icon on your .docx files. So if you suddenly find that the Microsoft Word icon is either blank or missing and does not show properly on .doc and .docx document files of Office on your Windows 10 computer, then you can check out the potential solutions outlined below. Before you proceed, you can try to restart your computer as there are instances when a simple system restart can resolve some issues like this one. However, if it does not help, create a System Restore point first. This is to ensure that you can always undo the changes you are about to make in case something goes wrong. Once you have that covered, proceed to the following options.

Option 1 – Try to configure .docx files to open with “winword.exe”

You can try configuring the .docx files to open with the winword.exe in order to fix the problem.

• Right-click on a .docx file and select the “Open with…” option.
• After that, if a prompt appears with a message saying, “How do you want to open this file”, select the “More apps” option to proceed.
• Next, scroll down and check the checkbox that says, “Always use this app to open .docx files” option.
• Then click on the “Look for another app on this PC” link and choose the WINWORD.exe application from one of the following paths based on the installed Office version in your computer and click Open:
  • Word 2016 (64-bit): C:/Program Files/Microsoft Office/root/Office16
  • Word 2016 (32-bit): C:/Program Files (x86)/Microsoft Office/root/Office16

• Now check if you can now see the Word icon on the .doc or .docx files.

Option 2 – Try changing the default Word icon via Registry Editor

• Tap the Win + R keys to open the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this path located in the left pane: HKEY_CLASSES_ROOTWord.Document.12DefaultIcon
• From there, double click on the default value at the right pane and based on the Word version you are using as well as the architecture (32 bit or 64 bit) and then copy-paste the corresponding value in the Value data box:
  • For Word 2016 (64-bit) keep it as C:/Program Files/Microsoft Office/root/Office16/wordicon.exe,13
  • For Word 2016 (32-bit) Keep it as C:/Program Files (x86)/Microsoft Office/root/Office16/wordicon.exe,13

• Once you’re done, tap Enter and then close the Registry Editor.
• Restart your computer and see if the problem’s fixed.

Option 3 – Try to rebuild the Icon cache

You may want to rebuild the Icon cache as it could also help fix the issue.

• Tap Win + E to open File Explorer and then click Folder Options and click Views to show Hidden System Files.
• After that, go to C:Users%username%AppDataLocal folder and look for a file named Iconcache.db and delete it.
• Next, go to C:Users%username%AppDataLocalMicrosoftWindowsExplorer.
• From there, look for the following files and delete them.
  • iconcache_32.db
  • iconcache_48.db
  • iconcache_96.db
  • iconcache_256.db
  • iconcache_1024.db
  • iconcache_1280.db
  • iconcache_1600.db
  • iconcache_1920.db
  • iconcache_2560.db
  • iconcache_exif.db
  • iconcache_idx.db
  • iconcache_sr.db
  • iconcache_wide.dd
  • iconcache_wide_alternate.db
• Restart your computer. This will purge and rebuild the icon cache.

Option 4 – Try fixing Office apps

Fixing the Office apps can help you resolve the Word icon issue. All you have to do is open Settings > Apps. From the app list, look for the Microsoft Office Desktop apps and select it and then click on the Advanced options and click Fix. After that, wait until the process is completed and restart your PC. However, if the problem still persists, repeat the steps again but this time, click on Reset instead of Fix.

Option 5 – Try to repair Office Installation

If the options given above didn’t work, you can try to repair the Office installation and see if it can fix the problem.

• Open Control Panel and click on Programs and Features.
• Next, right-click on the Office program that you want to repair which in this case is, Word.
• Select Change and click Repair > Continue. After that, Office will start to repair Microsoft Word.
• Wait until the process is done and then reboot your computer.

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system. The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges. The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control. Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.

As you know, Windows Hello offers you quick access to computers since you can log in to your Windows devices three times faster compared to passwords with the help of the camera via Face recognition and fingerprint reader. This way, Windows Hello will recognize you right away. However, there are also times when you might encounter some problems when using Windows Hello. For one, if you are trying to add the PIN method to Windows Hello on your Windows 10 computer but you suddenly encountered an error code of 0x801c004d or if you are trying to use your existing pin and you encounter an error code of 0x80070490 along with an error message that says, “Not recognized”, then read on as this post will guide you on how you can fix both of these errors. Here is the complete content for both errors:

• “0x801c004d – Unable to enroll a device to use a PIN for login”
• “0x80070490 - Not recognized, Pin and fingerprint are no longer options for signing in”

If you got any of these two errors, there are several potential fixes you can check out to resolve them. You can try to check for any Windows Updates or create the PIN again or check the CNG Key Isolation Service. You could also try to reset the TPM or create a new User Account. For more information, follow the instructions provided below.

Option 1 – Try checking for any available Windows Updates

The first thing you can do is to check for any available Windows Updates. It is possible that your computer may be outdated and is the reason why you’re having troubles with Windows Hello. To check for Windows Updates, just go to Settings and from there, head over to the Update and Security section and click on Windows Updates located on the left pane, and then click on the Check for Updates option. Wait until the process of checking updates is completed and if it finds new updates, install it. After you install the new Windows Updates, check if you can now add the PIN on Windows Hello or not.

Option 2 – Try creating the PIN again

The next thing you can do is to create the PIN again by signing out and signing in again and then try creating the PIN once more. If this does not work, you can try restarting your computer and creating the PIN again. You could also try removing the PIN and then change it.

• Remove the PIN by going to Settings > Accounts > Sign-in options.
• From there, go to the PIN section and click on the Remove button.
• You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
• Restart your computer and then set up a new PIN.
• Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try checking the CNG Key Isolation Service

The CNG Key Isolation Service is the one that stores and uses long-lived keys in a secure process complying with the common criteria requirements and it is possible that the error could be related to this service. This service is hosted in the LSA processes and provides key process isolation to private keys and associated cryptographic operations as required by the common criteria. Thus, you need to check this service to see if it’s the one that’s causing the error.

• Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, locate the “CNG Key Isolation Service” and once you find it, double click on it to open its Properties box.
• After opening its Properties, check its Startup type and select Manual. This is the default setting and if it is Disabled, then it’s no wonder why you’re getting errors with Windows Hello, thus, you need to enable it.
• Once done, restart your computer and check if you can now add the PIN to Windows Hello. If you still get the error, then you might want to try setting the CNG Key Isolation Service from Manual to Automatic and then click on the Start button and see if it fixes the error or not.

Option 4 – Try to reset the Trusted Platform Module or TPM

You might also want to try resetting the Trusted Platform Module or TPM to fix the error. You can do this by opening Windows PowerShell and then executing the “Clear-Tpm” command. After that, check if the error is now resolved.

Option 5 – Try to create a new User Account

You could also try to create a new User Account on your Windows 10 computer to fix the Windows Hello error. Once you have created a new local user or administrator account in Windows 10, check if you are now able to add the PIN from this newly created user account.

In case you don’t know, Windows contains a feedback mechanism that generates error reports from hardware and software problems. These reports are temporarily stored in the system and send them back to Microsoft so that it can find solutions to the reported problems and fix them in the upcoming updates.  However, as time goes by, these reports actually take a lot of space in your computer which is why end-users like you are free to delete them with the help of the new Free Up Space feature in Windows 10. As useful the Free Up Space feature may be, there are times when you won’t be able to use it for some reason which is why in this post, you will be guided on how to use alternative ways in deleting very large System queued Windows Error Reporting file, some of which may run in Gigabytes. Every time the Windows Error Reporting or WER sends out an error file and looks for a solution, the WER server at Microsoft sends out a solution instantly. And if the solution is under investigation or is unknown, then you will be notified about it right away and will be asked for more details. As mentioned, even though the Free Up Space feature in Settings will be able to clear the error reporting files, there are instances when it won’t be able to delete very large System queued Windows Error Reporting files. Alternatively, there is an option to delete these files using the Disk Cleanup Utility. Feel free to select which option you’d like to use to get rid of Windows Error Reporting Files.

Option 1 – Delete Windows Error Reporting Files via Settings

• Go to Settings.
• From there, go to System > Storage > Free Up Space and then click on it to launch it.
• Afterward, give it some time to populate all the files and folders. Once it’s done, select “System created Windows Error Reporting files” to mark its checkbox while leaving the other options unchecked.
• Next, click on the Remove files button to delete all the Windows Error Reporting files from your computer.

Option 2 – Manually delete the Windows Error Reporting Files

• Tap the Win + E keys to open File Explorer.
• Next, enable the Hidden Files view from the menu.
• Then go to C:/ProgramData/MicrosoftWindowsWER.
• From there, you will see various folders like LocalReportArchive, ReportArchive, ReportQueue, and Temp.
• Open each one of the aforementioned folders and delete the archive files. Note that these files will have names similar to “00c58c1f-b836-4703-9bcf-c699ca24d285”.

Note: If you are not able to delete any of these files, you have to take ownership of the folder. To do so, refer to these steps:

• Right-click on the folder and 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.

On the other hand, if you do not want to go through all these troubles in deleting the Windows Error Reporting files, you can just disable it especially if it already becomes a daily annoyance as the files generate every day and their sizes are mostly gigabytes. And besides, there are times when these files do not make it to the Microsoft WER server and end up only occupying a lot of space for nothing.

Daily Bible Guide is a browser extension developed by Mindspark Inc. for Google Chrome Browser. This extension offers users a fast and easy way to find Bible passages, view daily verses, study the Bible and view the current weather. When installed, this extension changes your default search engine and your home page to MyWay.

When installed this extension gathers user browsing information such as visited websites, search queries, clicked links, and other information. This information is later used to better target ads.

While active, you may encounter additional unwanted ads and sponsored links throughout your browsing sessions. Daily Bible Guide was marked as a Browser Hijacker by several anti-virus scanners, and due to its information mining behavior, it is considered a security risk and it is not recommended to keep on your computer; being flagged for optional removal.

About Browser Hijackers

Browser hijackers (sometimes known as hijackware) are a kind of malware that alters internet browser settings without the computer owner’s knowledge or approval. These kinds of hijacks are rising at a worrying rate around the globe, and it could be actually nefarious and sometimes dangerous too. There are plenty of reasons why you might experience an internet browser hijack; but commercial, advertising, and marketing are definitely the key reasons for their creation. Generally, the idea would be to force users to visit particular sites which are looking to improve their site visitor traffic and produce higher advertisement revenue. While it might seem harmless, these tools were created by malicious individuals who always attempt to take full advantage of you, so that they could make money from your naivety and distraction. Furthermore, hijackers can make the entire infected system vulnerable – other destructive malware and viruses will grab these opportunities to intrude into your computer effortlessly.

Signs of browser hijacker infection

The typical symptoms that signify having this malware on your computer are: home page is modified; you find new unwanted favorites or bookmarks added, typically directed to ad-filled or porn websites; the default search engine is modified; discover new toolbars which you did not add; you may see random pop-ups start occurring frequently; your internet browser has instability issues or exhibits frequent errors; you cannot visit specific websites like home pages of antivirus software.

So how does a PC get infected with a browser hijacker?

Browser hijackers attack computer systems via malicious email attachments, downloaded infected files, or by visiting infected sites. They sometimes are included with toolbars, add-ons, BHO, plugins, or browser extensions. A browser hijacker can also come bundled up with some free application that you inadvertently download to your computer, compromising your internet security. A good example of a popular browser hijacker is the most recent Chinese malware named “Fireball”, which has infected 250 million PCs throughout the world. It works as a hijacker but could be changed into a fully functioning malware downloader afterward. Browser hijackers will interrupt the user’s browsing experience significantly, keep track of the websites frequented by users and steal private information, cause difficulty in connecting to the net, and ultimately create stability problems, causing software programs and computers to crash.

Browser Hijacker Malware – Removal

Certain browser hijacking can be quite easily reversed by identifying and removing the corresponding malware program through your control panel. However, the majority of hijackers are extremely tenacious and need specialized tools to eradicate them. Additionally, manual removals require deep system knowledge and thus can be quite a difficult task for inexperienced computer users. Installing and running anti-malware programs on the affected computer could automatically delete browser hijackers and other malicious programs. Safebytes Anti-Malware features a cutting-edge anti-malware engine that will help you prevent browser hijacking in the first place, and clean up any pre-existing issues. In addition to anti-malware, a PC optimizer software, for example, Total System Care, will help you fix Windows registry errors, remove unwanted toolbars, secure online privacy, and stabilize software programs installed on the computer.

Malware Blocking Internet And All Antivirus Software? Do This!

Malware can cause a lot of damage to your PC. Some malware variants modify internet browser settings by including a proxy server or change the PC’s DNS settings. When this happens, you will be unable to visit some or all of the websites, and therefore not able to download or install the necessary security software to clear out the infection. If you’re reading this right now, you’ve perhaps recognized that virus infection is a reason behind your blocked internet connectivity. So how to proceed when you want to download and install an anti-malware program like Safebytes? Although this sort of issue will be difficult to get around, there are some steps you can take.

Switch over to some other web browser

Web-based viruses could be environment-specific, aiming for a specific web browser or attacking particular versions of the web browser. If you are not able to download the security software using Internet Explorer, it means the virus may be targeting IE’s vulnerabilities. Here, you should switch to an alternate internet browser such as Chrome or Firefox to download the Safebytes application.

Virtual Reality or VR for short has come a long way from its infant stage and as 2022 is in half period we are looking at the VR market and reflecting on what has changed in one year. For starters, games have increased in quality and quantity while the hardware price has decreased making the whole VR experience a little closer to a wider audience.

Many companies have tried to get on the VR bandwagon but also many have failed. What remained are staples in VR hardware from large companies that have started with VR early and kept improving their headsets.

So with great pleasure, we are presenting the remaining best 3 virtual headsets so far of 2022 brought to you from Sony, Valve, and Meta.

SONY PLAYSTATION VR

If you want VR on consoles then there is really one option, and that is SONY VR. Premium Virtual Reality solution from SONY, sadly you can do this only on Playstation 4 and Playstation 5. Sony managed to pull off great quality hardware and packed with its exclusives on playstore at a very affordable price that is still cheaper than other products.

While waiting for the Sony PlayStation VR2 headset this one is still a great option and quality is still among the top of the game. From the time of its release until today, many AAA titles have been released for it as exclusives that you can not play any other way and some of them are really worth it.

VALVE Index

Altho there are headsets like HTC Vive Cosmos Elite that have some features that place it as a better solution than Valve Index, Index is still an overall better VR headset as a whole product but its price is something that is keeping it still way out of reach of your standard user. The price, however, is really an illusion since it applies only when buying the system first time, you see Valve has created this headset as a modular design system making it upgradable meaning that you can, for example, buy newer controllers only and they will work perfectly with rest of hardware.

The modular design will save you money when you want to upgrade your VR system but as said entry price is steep. Besides its somewhat higher price than competitors, it is also notable that Index is a positional tracking VR set which means that it relies on a base station in order to locate the user. This means that once set, it is not so easy to change its location of use.

However, its quality and steam use are unmatched, high-quality games and compatibility that no other headset with steam will even pull off probably make Index one of the 3 best headsets out there. Half-life Alyx, arguably and currently one of the best VR games ever made so far was specifically designed for Valve Index and other games are behaving also incredibly nice with this headset, so if you want a great powerhouse for PC VR gaming, you will no go wrong in purchasing Valve Index.

META QUEST 2

Cheapest of the three and coming in various iterations, Meta has established itself from the beginning as a leading player in VR technology with its oculus line of products. Quest 2 is the next product in their line and it comes with 128GB and 256GB versions.

Meta has removed the need for the Facebook account for its VR systems and now you can use them without the need to send any kind of data to meta. Priced fairly for its entry 128 models this standalone VR set improves in any way possible from its previous iteration and sets the bar for what will come in VR's future.

Offering both wired and wi-fi connection with its standalone battery Quest 2 also is packed with a large library of games and it is user friendly as your typical game console but still allows some under-the-hood tinkering if you wish so.

Also, Meta's Vr solution since it uses inside-out tracking makes it incredibly easy to just pick it up and carry it with you wherever you go.

A black screen error inside Windows 11 is a typical screen turning to solid black without any error message. This can be very annoying since it can randomly appear out of nowhere and it will appear while you are using the computer. Worry not, this is not a serious error and we have several solutions for it, so please keep reading and try them as presented in order.

Restart graphic driver

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling. We have an article on errortools.com on how to properly clean your PC but if you are not technical enough maybe the best solution would be to call someone who is or to take the PC to service for cleaning.

Change The Projection Settings

Press WINDOWS + P to open projection settings, check to see if PC is set to PC screen only. If any other option is selected change it to PC screen only since this can cause random black screen issues.

Uninstall latest updates

If this problem has started to manifest itself during the latest update, go to setting and roll back from the latest update to fix this issue.

Scan system for malware

The black screen can also be caused by various viruses and malware. IF you have anti-virus software, run a full system scan to check it for malware. If you do not have one, download a free one and run a system scan, we recommend Bitdefender.
