How to Fix Error 0x80073712 in Windows

There are times when system files get corrupted and if the Windows Update process finds the system’s integrity questionable, chances are, the update, upgrade or the installation may fail and you will only be getting an error code 0x80073712 instead of completing the process.

The error code 0x80073712 indicates that a file needed by the Windows setup or the Windows Update is most likely missing or damaged. To resolve the problem, here are some suggestions you can try.

Option 1 – Try running the DISM Tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

  • Open the Command Prompt as admin.
  • Then type in this command: 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.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be causing the error 0x80073712. To run the SFC command, follow the steps given below.

  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 3 – Try running the Chkdsk utility

You can also try running the Chkdsk utility to resolve the Windows Update error 0x80073712. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

  • Open Command Prompt with admin privileges.
  • After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
  • chkdsk C: /r /x
  • chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed.

Option 4 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 5 – Try running Microsoft’s online troubleshooter

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.

What happened to Facebook and why it is down?
Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap. facebook downThe true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP. Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted, "By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform." Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things. Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages: "DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures." Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface. Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally." Technicians on site don't know how to do that and senior network administrators aren't on site. It seems that it will all be down for a couple of more hours before the issue is resolved.

GoDaddy data breach compromised 1.2M accounts
A very serious data breach has happened to the unfortunate GoDaddy hosting service placing a little over 1.2 million accounts affected. Security breaches sadly are not a rare occurrence but this time it is a little different. GoDaddy breachEach time when the company is breached data is stolen and that places the company in a bad light usually because its user database has been compromised and people are concerned about their data being misused. This is very rational fear and concern but this time things are a little bit different than usual, why is that, you might ask? Well, as before mentioned GoDaddy is a hosting company and the vector of attack was aimed at the part where it is hosting WordPress. Attackers were able to get their hands on the sFTP credentials of customers on that server meaning that all of the websites are also been relieved of their user base as well. This potentially means that there is a high chance that all of the hosted web site's content is also compromised, meaning that your data could also be compromised even if you were not a GoDaddy customer, all you needed to do is to be a member of any site hosted on their platform. GoDaddy has reset WordPress passwords and private keys, so it’s already taken the steps required to stock the attacker from exploiting anything with the passwords obtained. The company is in the process of generating new SSL certificates for customers. Bad thing is that the attack used a compromised password to get into systems all the way back around September 6th, 2021, the breach was discovered on November 17th, 2021, which is more than a 2-month active time where the attacker could harvest tons of data. The outcome of this attack will be seen in the upcoming time, until then be safe, and Just in case change your passwords.

Fix Microsoft Edge Error 0x80200070
As you know, any software needs sufficient CPU power when it downloads, updates and installs so if you encounter an error code 0x80200070 when you tried to install or update the Microsoft Edge browser on your Windows 10 computer, then read on as this post will guide you on how to fix it. This kind of error occurs when the Edge browser installation does not get enough CPU power to update or install and the only way to fix it is to kill programs that are consuming a lot of PC resources as well as stop or remove any unnecessary programs that are running in the background. This kind of error can also be encountered in the new Microsoft Edge Chromium. For more details, follow each one of the options provided below.

Option 1 – Try to kill applications that consume high resources

  • Tap the Ctrl + Shift + Esc keys to open the Task Manager.
  • Go to the Performance tab and sort by CPU usage.
  • Next, close a few additional programs that are consuming maximum CPU power.
  • After that, try to update or install Microsoft Edge again and check if the error is fixed. If not, try to restart your computer and then start the installation or update again.

Option 2 – Try to remove or stop unnecessary programs and services

If the applications or processes that are consuming a lot of CPU resources reappear even after you kill them or end their processes, then you can try the following suggestions to remove or stop these unnecessary programs and processes.
  • The first thing you can do is to stop the Service. If the program happens to be a service, then you have the option to disable the Windows Service. All you have to do is open the Services Manager and stop the service. How? Refer to these steps:
    • Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and tap Enter to open the Services Manager.
  • After that, identify which service is consuming a lot of power and then stop it temporarily.
  • The next thing you can do is to uninstall the problematic program. If the one that consumes a lot of resources is not a service but a program, then you can try to uninstall the program for the meantime until you’ve updated or installed the Edge browser. Once you’ve uninstalled the program, try to update or install Edge again.
  • You can also try booting your computer into Safe Mode and then update or install Microsoft Edge. This will make sure that all the unnecessary programs and services won’t consume a lot of CPU resources as well as memory.

Best MMO games to play during this winter
How summer is slowly slipping away and winter is coming people will spend more time indoors, and on top of that delta variant of Covid-19 is rampaging through the world. Being the gamer is now maybe the best time to be, sitting in the comfort of your home, safely isolated from viruses and people, just pushing buttons and emerging yourself in a vast world and new adventures. But games cost money, and sometimes being a gamer can be expensive, also the COVID situation makes it even more difficult to spend some time with friends. Do not worry, we are here to help. I am presenting you the list of MMO games that you should try or play during this COVID Winter, and since they are MMO games, you can play them with your friends and hang out in the virtual world. Some of them are also free to play so they will not cost you any money to enjoy them. The following list is not set in any particular order and remember that this is not a ranked list. There is no best MMO and I will not try to place any of these titles as one dominant, I will just point their style and who they might be for, it is up to you to decide which one you will pick and enjoy.

Best MMO’s in no particular order

EVE Online

eve online MMOEVE Online is one of the earliest MMO games out there but since its release, it is still actively developed and is receiving updates. This science-fiction Sandbox will offer space lovers everything they need and more. Large scale PvP, mining, pirating, etc. It can be daunting and complex for beginners but take your time to get familiar with its systems and you will be rewarded greatly with an immersive and complex game worth the time. Open PvP in some zones might not be everyone’s cup of tea and seeing only your ship might be a turn-off for some players, but if you do not mind these things give it a go. It is free to play with an item shop.

Final Fantasy XIV

ff14 mmoFF14 had a tough start, so tough that it was scrapped and destroyed and has been remade again and that idea was great. The game now is better than ever and at this time it is experiencing large players from other games surging into it. This on the rails fantasy MMO will offer you a great story and great leveling experience. It has a free trial where you can play the whole original game for free but if you wish to continue playing you will have to buy the expansion and pay a monthly subscription but the content is well worth the money.

World of Warcraft

wowLet’s be honest, not a single list of MMO games cannot be without a once greatest and most successful MMO ever made, World of Warcraft. But instead of me praising the game why it was the greatest and why you should play it and how great it is I am going to take a little different approach. I am going to recommend you World of Warcraft classic, yup, you read it correctly, classic. Now World of Warcraft is a retail game with a subscription service but with that one subscription you will be able to access three games in the World of Warcraft universe: World of Warcraft retail (standard game), World of Warcraft Classic (vanilla WOW without expansions offering you experience as it once was when it was released) and World of Warcraft the Burning Crusade classic (same as WOW classic but with the first expansion the Burning Crusade). Among all solutions, I would really urge you to play either WOW classic or WOW TBC classic simply for reason that they are far superior games in comparison to typical retail ones, but if you like easier game go for retail, it is included in the sub anyway.

Guild Wars 2

gw2Guild Wars 1 was one of my favorite games and I sank a lot of times in it and once Guild Wars 2 came I must admit I was pleasantly surprised with it and I would recommend it highly. The base game is completely free to play with only expansion to be purchased and it is buy to play model without monthly fees. It has specific mechanics different from other games and interesting classes to try. The living world is a great feature of the game and it is still very strong with its player base.

Star Wars: old republic

Star-Wars-The-Old-RepublicThis game is made for people who enjoy, love, and like Star Wars. Mechanically besides being able to have henchmen with you and space battles (which I do not really like how they are done) game itself does not offer anything special. Where it shines is in the story and overall Star Wars experience. If you look at this game as a single-player game with multiplayer dungeons you will have a great time, since the story is really good but sadly end game lacks in comparison.

Elder Scrolls Online

Blackwood-release-date-on-TESO-when-will-the-new-chapterI am going to admit something here, I was not fond of the idea to make the beloved Elder Scrolls series into MMO, but in time I gave it a go and I am really glad I did. This game is great and it is getting better and better as time progresses. It is buy to play without monthly fees and basic game free, same as FF14 but without fees. It has a decent community and offers a really good Elder Scrolls experience and now it is packing Morrowind expansions and other great areas. Highly recommended for any Elder Scrolls fan.

Lord of the Rings Online

Lord-of-the-Rings-Online-to-Receive-VisualTech-Updates-asThis one is troublesome to recommend, on one side you have free to play games deeply inside Tolkien Lord of the Rings lore, on the other side, you have outdated graphics and some stupid item shop decisions like buys specific classes. But if you look past stupid item shop decisions and can live with playing free class in the game you will be pleasantly surprised. The game itself is surprisingly good, the story is great as expected from the game infused with lore taken from one of the best books series ever written, and the feeling when visiting iconic landscape is epic. But if I need to be real as I should, I would recommend this one to people appreciate good story and lore and ones that are fans of Lord of the Rings itself.

Neverwinter

Neverwinter-Sharandar-Artwork-001Neverwinter is a premium and licensed D&D MMO game and it is well strange. The free-to-play model of the game will let you enjoy it until you hit the end game, then you will have to shell real money if you want to be competitive but the journey until then is great. I would recommend it to D&D lovers and people that love to try other people's maps, yup you read it correctly. Neverwinter has a map editor making it one of a kind MMO game where you can create your own dungeons and post them for other players to play, this user-generated content makes it a very specific beast in this list, and for that feature alone it has my recommendation.

Tera

tera-classes-guideAnother one of the older titles, Tera will offer you nor depth nor anything new in terms of leveling, quests, or end game except… the COMBAT. This is maybe the greatest MMO Combat game ever created and it is quite fascinating that even after so many years no other game has managed to create a better combat system than one of Tera. If you enjoy action combat and like some specific aesthetics Tera is a game for you.

Albion

Albion-Online-LaunchAlbion is a sandbox game with open-world PvP and building mechanics where you can build your own forest, house, etc. You know, sandbox stuff, including a lot of crafting and well, other sandbox stuff. If you want great quests and some occasional play then skip Albion, this game is made for a more hardcore player base not being afraid to die and spend some time crafting and going through the economy. The best comparison might be with EVE but in fantasy settings.

Black Desert

bdoBlack Desert is also a sandbox game but different from Albion, here you can organize and hire a workforce and send them to different nodes on a map to harvest resources and build an economy while you are on some epic adventure. Housing is also included but you can buy already made houses instead of making your own in the world. Combat is a game that comes very close to Tera combat and it is very enjoyable. The end game is money sink and PvP based so be careful when choosing this one.

Secret World Legends

the-secret-world-relaunching-as-1200x675If you like occult and supernatural with new world order themes and conspiracy theories, Secret World Legends is the game for you. Somewhat little clunky its setting and story really set it apart in many many ways. It has semi-action combat and it is free to play with item shop but all the content can be experienced for free. Recommended for fans of deeper gameplay and horror lore.

Runescape

runescapeWhen I said no MMO list can be without World of Warcraft, it also cannot be without Runescape, one of the oldest games it was revamped with newer mechanics and graphics, free to play all the way and you can also pick old school Runescape if you really want to go all the way on a nostalgia trip. I would recommend a newer one for newer players, the game offers a great story and unusual quests infused with puzzles and interesting storylines. If you like really good quest design without fetch and grind quests along with interesting story this is a game for you.

AION

aionLast on my list would be AION, a very interesting game made also a long way back, but the fact that is completely free with the cosmetic shop will make it as one to recommend since you can experience the whole game for free. It has some limited flying mechanics in it and later game zone are open PvP zones, story is interesting and leveling process is enjoyable. Also game itself is not really easy and if not careful you can get yourself in danger quite quickly. Recommended for old-school feeling.

Conclusion

That's it, there are many more MMO games out there but some are on verge of closing down and some are plainly bad. I hope that I have made your choice easier and that you will find one or a few from this list to spend your time in it. Remember, stay safe and take care of yourself.

UNMOUNTABLE_BOOT_VOLUME
One of the worst Blue Screen of Death errors you can encounter is the UNMOUNTABLE_BOOT_VOLUME BSOD on Windows 10. In this BSOD error, your computer won’t be able to properly boot. Meaning to say, even if you want to reinstall Windows, you won’t be able to back up your important files. Thus, it wouldn’t be really feasible to fix the system files, and besides, reinstalling Windows 10 would take a lot of time, not to mention resources. The UNMOUNTABLE BOOT VOLUME error is the kind of BSOD error that occurs if Windows is not able to access the volume that contains the boot files. Resolving this BSOD error won’t be easy but you will surely manage by following the suggestions laid out below but before you go on, make sure to create a System Restore Point.

Option 1 – Try checking the hardware

If you got the UNMOUNTABLE BOOT VOLUME BSOD error while trying to update your computer to a higher version of Windows, then you need to check if you have the compatible drivers for the disk controller as well as re-check the drive cabling and make sure that it is properly configured. And if you’re reusing either ATA-100 or ATA-66 drivers, ensure that you have an 80-connector cable and not the standard 40-connector IDE cable.

Option 2 – Try using Automatic Repair

You might also want to use Automatic Repair in fixing the BSOD error. To do so, follow the steps below.
  • You can start by creating and booting from a bootable Windows 10 USB Stick.
  • After that, click on Repair your computer located in the bottom left corner when you are on the initial Windows Startup screen.
  • Next, click on Troubleshoot, and then on the other screen, click the Startup Repair option.
  • Now select the operating system you want to repair. Once you do that, it will start to repair your operating system. Wait until the process is completed and then check if the problem’s now fixed.

Option 3 – Try fixing the Master Boot Record or MBR

The MBR or Master Boot Record is the location and is where the architecture of the operating system is installed. Thus, if either the location or the architecture has tampered with, it can cause lots of BSOD errors like the UNMOUNTABLE BOOT VOLUME error.
  • Boot your computer into Safe mode with Networking using the Advanced startup options which you can access by tapping the F2 or F8 key. Once you’ve accessed the Advanced startup options.
  • After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
  • After opening Command Prompt, execute the following command and hit Enter:
bootrec /fixboot
  • After entering the command, wait until the process is completed and then restart your computer to apply the changes made successfully.

Option 4 – Run the CHKDSK command to repair hard disk errors

Running the Chkdsk utility could help you fix the UNMOUNTABLE BOOT VOLUME error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.
  • After you access the Advanced Startup options, select Command Prompt by using the arrow keys on your keyboard.
  • After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
  • The command you entered will scan the hard disk for any errors and will automatically fix it if it finds some issues. Wait for the process to be completed and then reboot your PC.

  6. Open Windows Update once again and see if the installation of this pending update is now successful.

Installing the pending Update Manually

Whether you’re experiencing this issue with an integrated webcam driver or with anything else, chances are you’ll be able to circumvent the apparition of the 0x800705b3 error by using the Microsoft Update Catalog to find, download and install the pending update manually.
  1. Open your default browser and navigate to the root web page of the Microsoft Update Catalog.
  2. Once you’re inside the Microsoft Update Catalog, use the search function (top-right corner of the screen) to search for the update that is failing.
  3. After the search is completed and you get the list of results, look for an updated driver version that is compatible with your Windows version and CPU architecture.
  4. Once you manage to identify the correct Windows Update, click on the hyperlink associated with the update that you want to install, then click the Download button and wait for the process to complete.
  5. After the download is complete, use File Explorer to navigate to the location where you previously downloaded the update.
  6. When you get to the correct location, right-click on the .inf file and choose Install from the context menu that just appeared. Note: If you have multiple failing updates with the same 0x800705b3, repeat the instructions above with every Windows Update that you’re having trouble installing.
  7. At the end of this operation, reboot your computer and see if the problem is fixed at the next computer startup.

Enabling the Windows Installer Service

The Windows installer service is responsible for installing pending updates that get downloaded by the Windows Update component. If this service is disabled on your configuration, none of the updates waiting to get installed will get completed.
  1. Press ⊞ WINDOWS + R to open up a Run dialog box. Inside the text box, type ‘services.msc’ and press ENTER to open up the Services utility.
  2. Once you’re inside the Services screen, move over to the right-hand tab of the screen, scroll down through the list of services and locate the Windows Installer service. When you find it, right-click on it and choose Properties from the context menu that just appeared.

Note: If you can, also change the Startup type to Automatic via the associated drop-down menu. However, depending on your administrator settings, this might not be possible.
  4. Restart your computer and wait for the next startup to complete. Once your PC boots back up, attempt to reinstall the driver that was previously triggering the 0x800705b3 error and see if the issue is now fixed.

Performing a Winsock Reset

In case the 0x800705b3 error is related to some kind of network inconsistency (TCP or IP related), you might see Windows Updates failing due to bad data that forces the Windows to abort the installation of new pending updates. In this case, you should proceed by doing a complete Winsock reset procedure to fix the majority of the socket and temporary data-related issues that might cause this behavior. Several affected users have confirmed that this method was the only thing that allowed them to finally fix the Windows Update issue and install pending updates normally. Here are some step-by-step instructions that will walk you through the process of performing Winsock Reset:
  1. Open up a Run dialog box by pressing ⊞ WINDOWS + R. Inside the text box, type ‘cmd’, then press CTRL + SHIFT + ENTER to open up an elevated Command Prompt. Accessing an elevated CMD prompt Note: When prompted by the UAC (User Account Control) prompt, click Yes to grant admin access.
  2. Inside the elevated CMD prompt, type and taste the following commands in order and press ENTER after each one to effectively reset the TCP and IP data that might be responsible for the apparition of the 0x800705b3 error code:
    nbtstat -R
    nbtstat -RR
    netsh int reset all
    netsh int ip reset
    netsh winsock reset
  3. Once every command above is processed successfully, you can go ahead and close the elevated Command Prompt and reboot your computer.
  4. After the next startup is complete, repeat the installation of the Windows Update that was previously failing and see if the issue is now fixed.

Performing SFC and DISM Scans

If none of the ‘superficial’ causes have worked in your case, you should start considering some type of system corruption that might affect your computer’s ability to complete pending updates that are currently waiting to be installed. In case you find yourself in this particular scenario, you should run a couple of built-in utilities capable of fixing corrupted instances that might be currently affecting the Windows Update component. Our recommendation is to start with a simple System File Checker scan. An SFC scan will cross-check every Windows File against a local archive that maintains healthy copies. In case corrupted instances are found, this utility will swap the corrupted instance with the healthy equivalent.

Performing an SFC scan

Once the SFC scan is complete, reboot your computer and wait for the next startup to complete. After your computer boots back up, initiate a DISM scan. This utility works differently in the sense that it relies on a sub-component of Windows Update to download healthy copies for the corrupted Windows files that need to be replaced. Because of this, it’s important to make sure that you have a reliable Internet connection before initiating this operation.

Doing a DISM scan

After the DISM scan is complete, reboot your computer one final time and see if the issue is fixed once the next startup is complete.

About Browser Hijackers

Browser hijacking is a form of unwanted software, commonly a web browser add-on or extension, which causes modifications in web browser’s settings.

They can also be deployed via the installation of an internet browser toolbar, extension, or add-on. A browser hijacker could also come bundled up with some free software that you unknowingly download and install the browser hijack, compromising your PC security. Some of the most well-known hijackers are AudioToAudio, Babylon Toolbar, Conduit Search, OneWebSearch, Sweet Page, and CoolWebSearch.

Removing browser hijackers

Some hijackers could be removed by just uninstalling the related freeware or add-ons through the Add or Remove Programs in the Microsoft Windows Control Panel.
