How to Manually Fix 0x8004210A Error Code on Your System

Hive ransomware has been targeting Microsoft exchange servers lately vulnerable to ProxyShell security issues in order to deploy various backdoors. Once the backdoor has been placed various attacks can be performed including but not limited to network reconnaissance, stealing admin accounts, taking valuable data, and even installing and deploying file-encrypting algorithms.

ProxyShell wide abuse

ProxyShell is a set of three vulnerabilities in the Microsoft Exchange Server that allows remote code execution without authentication on vulnerable deployments. The flaw has been used in past by various ransomware like Conti, BlackByte, Babuk, Cuba, and LockFile.

Security vulnerabilities have been reported to be fully patched on May 2021 but how Hive was able to still be successful in exploiting PowerShell and infiltrating into the system there seems to be still some unpatched and open issues.

Hive

Hive has gone a long way since it was first observed in the wild back in June 2021, having a successful start that prompted the FBI to release a dedicated report on its tactics and indicators of compromise.

In October 2021, the Hive gang added Linux and FreeBSD variants, and in December it became one of the most active ransomware operations in attack frequency.

Last month, researchers at Sentinel Labs reported on a new payload-hiding obfuscation method employed by Hive, which indicates active development.

In today's age of smart gadgets and complete replacement of even some simple things with their smart counterpart, it is not really a surprise to see some strange innovations that try to take advantage of modern technology.

One of these innovations is a smart book, or to be more precise smart note, a reusable notebook that could be connected to your phone.

Why Rocketbook Fusion smartbook

One thing that could justify, well it should justify buying Rocketbook is the preservation of trees and the environment since it can be reused. The second argument would be its price since it is not expensive considering what it offers.

On top of all, you also have a free application for your phone in order to take full advantage of it.

What is a smartbook?

Imagine this scenario, you have a notebook of 42 pages with several different page styles inside. You write in it and after it is filled you upload its content to your email or cloud service of your choice, get a cloth, erase everything and start again from zero.

So as mentioned notebook comes with 42 pages of various page styles. Most of the pages are either lined or dotted but the notebook also includes a monthly calendar, two-week detailed calendar pages, and three pages for project or idea tracking. Since everything can be erased this is enough variety to cover all basis and eliminate any need for another workbook ever.

When you feel like you want to save work or once it is filled you can easily upload and save the workbook from the scan page option in the free Rocketbook app. Once scanned pages can be uploaded to your preferred cloud service or sent to your email.

Now in order to write and be able to erase any of Rocketbook's notebooks, you will have to use Pilot's Frixion writing pens. They will dry around 15s on the page and can be of course easily wiped with a damp microfiber cloth that is included with the purchase. One pen also comes with a workbook when purchased.

Application

Application has cool features, of course, the most important and most useful one is setting your upload scan destination so when you scan your pages they get automatically uploaded to your chosen destination.

In the application settings, you can also toggle some handwriting recognition features that will allow you to easily search your uploaded documents. For example, you can search through documents just by writing now or two words. There is also a Smart List feature as well that will take your checklist and make it into a virtual checklist.

The app also has a fun Explore section where you can find all sorts of fun hacks and different ideas on how to use your Rocketbook.

Mapping network drive has many benefits in terms of speed and ease of access of files via network. It lets you access the hard drive over the whole network like it was the hard drive inside your PC case. In order to easily and quickly map a folder as a network drive follow the guide below.

1. Open File Explorer
2. Click on the three dots icon in the Toolbar
3. Select Map Network Drive
4. Click the Drive drop-down menu
5. Select a driver letter that you wish to assign as a network drive
6. In the folder field enter network device and share name (click on browse to see all devices on local network)
7. Check the box beside Reconnect at sign-in if you wish to automatically connect to a network drive on Windows startup
8. Check Connect Using Different Credentials if you wish to connect to a network drive using different credentials that one used to login into Windows.
9. Click Finish

After finishing setting Windows 11 will try to connect to the network drive and if successful drive icon will appear inside File Explorer and the drive will open up to see its content. If for any reason it cannot connect try checking user credentials, cables, network adapters, etc.

As you probably know, Windows 10 does not offer lots of choices for its Regional settings depending on where you are and what locale you work with or belong to. The standard region settings for Windows 10 allow users to select one set of formats for the calendar and more. However, this has somewhat changed in the Windows 10 v1809. If you don’t want such a change, you can just override the default regional format settings in the Windows 10 Improved local experience. So in this post, you will be guided on how you can do such a thing. Follow the given instructions below to override the default Regional Format settings in Windows 10. Step 1: Go to Settings > Time and Language > Region. Step 2: From there, the default region is what Windows and apps might use to provide you with local content. However, this won’t be much of use if you work for a different locale and need to have different format settings like Calendar, Dates, Times, Currency, and First day of the week, all of which you can modify under the Regional format. Step 3: You need not reboot your Windows 10 computer after changing. On the other hand, some of the apps will have to close and launch again in order to apply the new format. Thus, if you need to use apps that are of different locales, you will only see the changes after you re-launch the app. Note: You can also select a different language that makes more sense to you. In other words, if you prefer more common words to standard words for your Windows 10 computer, then this is definitely the way to do it. This local format will be used for messages, menus, navigation, settings, and other topics. Step 4: Look for a link that says “Add a Windows display language with local experience packs” under Languages. In case you don’t know, Local Experience Packs are Microsoft Store apps that deliver Windows display language quality improvements. So once you click the link, it will download the packs from the Microsoft Store. In addition, Windows has already begun using AI or Artificial Intelligence as well as neural network-based Machine Learning for Windows localization. And as the number increase, the Machine language improvements and feedback from users will help in making the translations a lot better and make them available to even more languages. All in all, it’s pretty much an interesting and a good move for Microsoft as the demands for topics and machines to be available in local languages have been increasing for the past couple of years.

You can prevent starting of app installations files if they have not come from the MS store inside Windows 11. This can make your PC more secure because all apps in the store will have to be digitally signed and overall it can provide you with more control over what will be installed. Follow the guide below to find out how can you easily turn this feature ON.

1. Press ⊞ WINDOWS + I to open Windows settings
2. Select Apps and then choose Apps & Features
3. Click on Choose where to get apps to bring a drop-down menu
4. Select The Microsoft Store only (Recommended)
5. Close settings

Settings will apply changes immediately and you continue using Windows right away. With these settings turned ON if you want to install a downloaded application or run the installer you will not be able to, and message The app you’re trying to install isn’t a Microsoft-verified app will show on your screen. You can always reverse this setting by choosing Anywhere in settings instead of Microsoft store only.

If you own an iPhone, iPad, or iPod you might be aware of the phenomenon of connecting and disconnecting your device. In one moment device is connected and then it somehow loses connection and you have to plug in back again to be recognized. In this troubleshooting guide, we will address ways to eliminate this issue and to connect and have your devices working properly. We will go from the most common ones to the most uncommon so it is advisable to try solutions in order to how they are presented.

1. Check cable

   The most common issue with this kind of behavior comes from a broken cable if you have the opportunity try another working cable to see if the device will behave differently. If everything is working fine with another cable, the issue is in the previous cable.

2. Check USB ports and Cable Jack

   Usually, it is a cable issue, but it can also be a USB jack on cable or even a USB port on a PC, try putting the jack into another port to see if this will solve the issue.

3. Check device settings

   From updates on your device comes a change of setting about privacy which can reflect on connection with the computer. In order to eliminate this, you will need to reset your device. Go to device settings and go to general Scroll down until you find the reset section and go into it In the reset, section click on reset location and privacy You will have to authenticate using your pin/passcode in order to complete the reset function Enter your passcode (or use any other authentication method you have chosen) and you can now reset the Location and Privacy settings. Click on reset Connect the device to PC and choose trust this device

4. Update iTunes

   Outdated iTunes can also be a problem with this particular issue. Go to the apple website and download the latest version of iTunes or updating it via apple updater.

Valve has released a big update to its online store and distribution platform Steam. Among typical bugs fixing and making the user experience a little more fluid, we have received some major updates as well. Please take note that you need to update Steam itself to the latest version in order to get new features.

Storage management Page update

The storage management page has received a complete redesign and UX overhaul and it is now much easier to manage your game libraries and create new ones. The page itself looks and feels a little console more like but thanks to that it offers a much easier and clearer look and feel. Another thing with the Steam store management page is the ability to move installation files from one location to another. Let’s say that you have two or more hard disk drivers in your machine and that you have SSD that you use for running stuff since it is fast and larger and slower one for storage. Now you can easily and quickly move one installation from one to another in order to take advantage of your faster SSD for quicker LOAD game times without making a new installation.

Steam Download page improvements

The download page has also received some love from Valve by enabling us to now see the installation progress. So far on the download page of Steam, you would only get download progress but it has been updated to show installation progress after download as well now making it more straightforward and giving you a general idea of how much more time there is to wait in order to start gaming. Also, you can now drag and drop items in the download bracket to reorder download orders or place them as active downloads to start downloading right away.

DirectX function GetDeviceRemovedReason error is a DirectX error that comes up during playing games on Windows 11 operating system. Usually, the error occurs in gaming systems powered by AMD and very rarely if any times at all on Nvidia or intel platforms. If you are one of the gamers affected by this error, fear not because we have a solution for you. Follow provided fix guide in order to correct this error and get back to gaming asap.

1. Update drivers

The first thing of course is to update your graphic card driver, you can do this with your graphic cards panel software or directly in Windows itself but the best practice and one that I would recommend is to go to your graphic card manufacturer’s website and download the latest driver there, and then install it inside Windows 11.

2. Change power mode

Changing power mode inside Windows 11 can solve this issue since sometimes Windows power manager if it is set to anything except best performance can interfere with the proper functioning of the graphic adapter, and because of this error. To change the power setting do the following:

1. Press ⊞ WINDOWS + I to open settings
2. Click on the System tab
3. Select power & battery on the right part
4. Click on the menu beside power mode
5. Select the best performance

3. Run SFC scan

Corrupted system files can also cause this error and if previous steps have not resolved it we will use Windows built-in tool SFC scan to find and repair all bad files in windows.

1. Press ⊞ WINDOWS + S to open the search menu
2. Type in Windows terminal and run it as administrator
3. If prompted click on YES on UAC
4. Press CTRL + SHIFT + 2 to run command prompt
5. Type in sfc /scannow and press ENTER
6. Wait for the whole process to finish and then reboot your system

4. Reinstall the problematic game

Sometimes game files can get corrupt and maybe even overwritten, try with game reinstallation if the problem still persists.

The System32 folder contains vital configuration and information that are essential to the operating system. It is located inside the “Windows” folder and it consists of important DLL files as well as executable files. You probably have noticed some errors that have the “System32” word in them but that does not necessarily mean that the System32 folder is the one that triggers them as these kinds of errors have only occurred when some important files are corrupted or missing. Some users recently reported that each time they start their computers, the System32 folder will automatically open up in the File Explorer. If you encounter the same problem, read on as this post will guide you on what to do to fix it. This kind of issue is most likely caused by service or application interference – it is possible that there is a third-party application installed in your computer or a Windows service that triggers the System32 to pop up during startup. It is also possible that this is a result of system modification. Thus, you need to identify the third-party program or restore your computer to its previous state.

Option 1 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• 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.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

• From the “Start” menu, go to System Configuration.
• After that, switch to the General tab and click the option for “Normal Startup”.
• Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
• Then find and click “Enable all” and if prompted, you have to confirm.
• Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
• Restart your PC when prompted.

Option 2 – Perform System Restore

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run System File Checker scan

You might also try running the System File Checker or SFC scan to fix the issue. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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.

 Restart your computer and see if the System32 folder still pops up at startup or not.

Can graphic cards wear out over a longer period of time? Recent studies and experience from crypto miners say no but they can die due to different reasons like improper use, low cleaning habits, factory mistakes, etc. Many gamers and people who use GPU intense applications tend to think that some glitches and hiccups in the software are a sign that graphic card is dying out and that it is time to be replaced. Altho this could be true in many cases these kinds of behavior are mostly due to old drivers and software issues. Older cards can produce these kinds of results due to their old age and new software is often more demanding than these cards can handle. So in order to diagnose and be sure that your GPU is indeed dying out lookout for these signs.

The Main Signs of a Dying GPU:

The Computer Crashes and Won’t Reboot

If your computer shutdown while working in the graphic application or while playing the game and the monitor loses signal there is a high chance the graphic card is soon going to be gone. Some motherboards have hardware detection failure and can signal immediate fail. If when turning your computer ON you are greeted with a blue screen with the message that the signal can not be found or you do not have picture at all it is most likely that GPU has failed.

Graphic Glitches While Playing Games

If you are playing the game and all of sudden you get off-color pixels, screen flickering, strange graphic behaviors, random artifacts, or similar and that keeps repeating in multiple games it is likely that GPU days are coming to an end.

Abnormal Fan Noise or Performance

Fans are an essential part of cooling the GPU and over time if they are intensively used they could wear out and need replacing. If however you have not noticed and have not replaced the fans card can sustain overheating damage. Many cards have cooling fans that are designed to spin at a higher RPM only when the GPU is under load. It prevents bearings in the fans from dying prematurely, so don’t worry if one of your fans is inactive while you are browsing the web. However, when you play games that utilize software that your card isn’t built to support, the bearings in the fans wear out faster. Once the fans stop working under load, the graphics card can quickly die.

How to Diagnose a Dying Graphics Card

Presented next are essential steps in order to recognize a dying graphic card.

Check Motherboard Error Codes

Many motherboards today completely shut down a component that is no longer working. If your graphics card has died completely, this may be one of the easiest ways to tell. If your motherboard doesn’t have display codes, you can try testing the card in a new system.

• Open the computer case: Use your screwdriver to remove screws on the side panel and gently slide it back.
• Locate the error code display on your motherboard: If you have a motherboard with error codes, they should appear near an outer corner.
• Try to reboot your computer: Record each error number you see after you boot your computer.
• Consult the motherboard manufacturer manual for error codes: Open the manual and locate the list for your error codes. If the code matches a graphics processing unit error, your video card could have died.

Check Hardware for Damage or Debris

A graphics card that has damage or debris on the physical parts might quickly overheat and kill the card.

• Remove the screws holding the GPU in place: There are typically one or two screws holding the card to a bracket on the case.
• Unhook the power cords from the GPU and pull the release tab: Remove the power cords from your GPU by pushing in their tabs and gently rocking them out. Once you remove each cord, gently push or pull up on the release tab near the motherboard.
• Inspect the GPU for damage/debris: Check the card for any dirt or debris buildup and clean it out with a Q-tip. You can replace broken fan pieces from the manufacturer.

Test Your GPU Under Load

Download GPU stress-testing and heat-monitoring software.

• With the card installed, run a stress test.
• As you are running the stress test, run heat-monitoring software: With the stress test running, check your heat-monitoring software for GPU overheating. Any reading over 80 degrees Celsius is too hot.
• Check device manager for outdated drivers: If your GPU is clean, but still running too hot, your software drivers are not installed correctly. To check, type in “device manager” at the bottom of your desktop and click on Device Manager. Find your display adapter and right-click on it to see if it’s working. If your drivers are not working correctly, it is indicated here usually. However, the driver may appear to be functioning even if it says otherwise in the properties.

Keep your graphic card drivers updated

When you don’t have the right driver installed, graphics cards can quickly burn up, and their cooling components may fail faster. That’s why you should always keep drivers updated for each new game you install or play. Older games may also release new software patches, so your GPU drivers should be updated accordingly.
