Fix Windows errors 80240020, 8007002C, 80246007, 80070004
Upgrading your Windows 10 computer does not always go smoothly and you often encounter not just one but various errors so, in this post, we are going to cover several Windows 10 upgrade errors such as 80240020, 8007002C, 80246007, 80070004. All these upgrade errors are related to the Windows Update folder. Thus, you need to clear the Software Distribution folder, repair the System Image and fix System Health in order to resolve all these Windows 10 Upgrade errors. Before you get started on the steps to resolve these tons of errors, you have to disable your security program for the meantime, disconnect your peripherals, remove USBs connected to your PC and then make sure that your PC is connected to the main power supply. Once you have everything covered, carefully follow the options given below.

Option 1 – Delete Windows 10 Update Files in the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. A lot of users tried deleting the files in this folder to fix the problem and so far it has worked. Like them, you can try clearing the Windows Update cache by simply deleting the contents of the folder named “SoftwareDistribution” since Windows apparently can’t clear and re-download the update contents once they are corrupted. Thus, deleting the contents of this folder will make Windows download the contents again which will fix the problem. To do that, follow the steps below.
  • Open the WinX Menu.
  • From there, open Command Prompt as admin.
  • Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv net stop bits
  • After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
  • Next, go to the C:\Windows\SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
  • Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.
net start wuauserv net start bits
Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.
  • Now Open Settings and check for Windows Updates. Windows 10 should begin the download right away.

Option 2 – Try using 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 with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • 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.
Note: If it happens that the Windows Update client is broken, you need to run the following command to repair it then restart your PC and click on Update once again.
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess
Note: The Windows Upgrade error, with error code 80240020 is an expected error message that happens when the upgrade requires customer user action. Thus, you need to do the following steps to resolve this particular Windows Upgrade error.
  • Tap the Win + R keys to open the Run dialog box.
  • Then type “regedit” in the field and hit Enter to open the Registry Editor.
  • After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionWindowsUpdate
  • Now right click on WindowsUpdate located in the left pane and then create a new key and name it as “OSUpgrade
  • Next, right-click in an empty space in the left pane and create a new DWORD and name it “AllowOSUpgrade” and enter “1” as its value.

Option 3 – Try running the Windows Update in a Clean Boot State.

Putting your PC in a Clean Boot state can also help you install Windows Updates or Upgrades without any trouble because, during this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.
  • 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” checkbox 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” checkbox.
  • 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 that, try to install the Windows Updates or upgrade again.

Malware Guide: How to Remove BitCoinMiner

What is BitCoinMiner Malware?

BitCoinMiner is a Malware created with the intent to force computer systems to generate crypto-currency, namely Bitcoin. This is done without the consent and knowledge of a computer/system holder. This unwanted file bears no digital signature or publisher since the creators of such a heinous invention do not wish to be known. Technical details about BitCoinMiner Malware include:
Product Version: 1.0.0.0 Original File Name: crss.exe Entry Point:  0x000C5AAE

Assessment of BitCoinMiner Malware

After installation of the BitCoinMiner Malware, there were no visible signs of an infection or program files installed. However, based on research, BitcoinMiner Malware utilizes the CPU’s resources (est. to be about 50%). Computer users have reported that they recognized an unknown process utilizing the majority of their processing space. the bitcoin miner is used by the creators to penetrate a user’s system, in effect coercing each infected system to mine Bitcoins covertly. After years of mining, a user might discern that their computer is moving slouchy and may even encounter various forms of BSODs.   After Bitcoins have been mined in the infiltrated system, the cyber currency is then returned/ sent to the creator of the malware. This venture is a sly and deceptive way to earn Bitcoins since the currency is gaining much popularity.

Further Information on BitCoinMiner

BitCoinMiner works covertly. There are no obvious traces of this program running on a computer system. However, once a computer system is infiltrated, the computer user will realize that their CPU resources are strangely being used up, even while the computer idles. Another expression of BitCoinMiner is the addition of cookies of various sorts to a computer system. These include:
  • Tracking cookies
  • Advert (Adware) cookies
  • Casale Media (Spyware) cookies
  • Atwola (Spyware) cookies
  • Adtech (Spyware) cookies
Once BitCoinMiner is present on a computer system, it can potentially slow it down and also create back doors as a means to install other unwanted and harmful programs. To completely remove BitCoinMiner Malware from your computer, click here to download and install Spyhunter.

Mac/Linux:

Specify the Autodesk Network License server information in $HOME/.flexlmrc file.

Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop. The file content should look like this, except with the name or IP address of the license server.
  • ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP
If the license server is on the same machine as the Autodesk software, use localhost as the license server name.  Thus, the content of flexlmrc file could look like this:
  • ADSKFLEX_LICENSE_FILE=@localhost
Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP

Once flexlmrc file is created move it to user's $HOME folder as follows:

  1. Open a Terminal window
  2. Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
  3. Drag and drop flexlmrc.txt file from Desktop to the home folder.
  4. To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:
  • mv flexlmrc.txt .flexlmrc (Mac)
  • mv flexlmrc .flexlmrc (Linux)

Verify that the license server information registered with the product is correct (versions 2020 and later only)

In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with AdskLicensing and result in the error above, if this is not appropriately updated. See the below steps to solve this:
  1. Click the Start menu and type cmd.
  2. Right-click on the Command prompt and choose "Run As Administrator."
  3. In the Command prompt, run the following command, followed by ENTER:

"C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\helper\AdskLicensingInstHelper.exe" change -pk PRODKEY -pv VER.0.0.F -lm "" -ls "" -lt""

Note:

  • Replace PRODKEY with the product key correspondent to your product(s). See Look Up Product Keys for the full list.
  • Replace VER with the version you are using. E.g. 2020 for AutoCAD 2020.
  • Repeat this step for each software you need to reset.
  1. Open Registry Editor (Start > type regedit > ENTER).
  2. Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
  3. On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
  4. Run the software again.
  5. Select Multi-user in the Let's Get Started screen.
  6. Follow the steps to connect to your license server.

Fix Google Chrome screen flickering issue
If you are using your Google Chrome browser and suddenly notice a constant flickering after you’ve upgraded your Windows 10 computer, read on as this post will help you sort out the issue. A lot of users have reported this screen flickering issue in Chrome after having upgraded their devices to a recent Windows 10 build. The bizarre thing about this problem is that it only affects the Google Chrome browser and when it occurs, the Chrome browser will start to flash or flicker. According to users who experience the problem in Chrome, it seems to get worse when they try to play videos on YouTube or other streaming sites. To resolve this problem, many users tried to use Chrome in Incognito Mode, cleared the browser cache as well as cookies. They even tried resetting the browser settings and reinstall Chrome but nothing seems to work. Worry not though as there are still other options you can try to fix the problem and they’re easy ones so you’ll have no problem following them. The screen flickering problem in Chrome appears to be related to the Windows background and color settings as well as incompatible display drivers. This is why it is advised that you have both the video card drivers and Chrome browser updated to prevent the same problem from happening again. To get started troubleshooting the screen flickering issue in Chrome, refer to the following options.

Option 1 – Try modifying the background and colors settings

  • Tap the Win + I keys to open the Settings app.
  • From Settings, go to Personalization to load the Background Preferences and if this window does not appear, just select the Background option from the left side panel.
  • Next, select a Solid Color as the new background from the drop-down menu.
  • After that, check if the problem is fixed. This should be fixed especially if the one that’s causing screen flickering is the Windows automatic background switching.
  • Once you’ve selected the Solid color as the background preference, go to the Colors tab under Personalization. This will open a new window and from there, check the box of the “Automatically pick an accent color from my background” option.
  • Now close the Settings app and open Chrome again.

Option 2 – Try to update or rollback the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:
  • First, boot your computer into Safe Mode.
  • After that, tap the Win + R keys to launch Run.
  • Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.

Note: If updating the Graphics driver didn’t fix the problem, you can also try to roll back to its previous version and see if that helps.

Option 3 – Try to disable the Hardware Acceleration

For better performance, Google Chrome uses the Hardware Acceleration by default. Unfortunately, there are just some cases when your hardware, GPU to be specific, might not be able to cope with the requirements, resulting in the black screen issue. And if this is your case, you should try to disable the hardware acceleration from your Google Chrome browser settings panel. To do so, follow the steps below.
  • Open the Google Chrome settings page.
  • Click on the Advanced button to get more options.
  • Look for the option called “Use hardware acceleration when available” and then disable it by toggling the button to the left.
  • After that, check if the screen flickering issue in Chrome is fixed.

Option 4 – Try to disable “Smooth Scrolling” in Chrome

Disabling “Smooth Scrolling” in Chrome might also help you fix the issue. To do so, follow these steps:
  • Open Chrome and type “chrome://flags” and hit Enter.
  • Next, look for a flag named “Smooth Scrolling”. You can scroll down until you find it or search it in the Search Flag bar. Note that Smooth Scrolling is enabled by default in the newer versions of Chrome.
  • After that, select the drop-down menu and select Disabled.
  • Then click on the “Relaunch Now” button.

If you suddenly encounter the SPECIAL POOL DETECTED MEMORY CORRUPTION Blue Screen error with a bug check value of “0x000000C1” while you are using your computer then it might be due to some problem with the hardware of your Windows 10 computer. According to security experts, it is most likely caused by the physical RAM which could be due to some error in the Realtek driver for Wireless USB 2.0 as well as corruption of the files inside the RAM, and so on. This kind of problem indicates that the driver wrote to an invalid section of the special pool. On the other hand, system files like the rtwlanu.sys or nvlddmkm.sys can also trigger the SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION Blue Screen error. To resolve this Blue Screen error, you can use the options provided below as reference but before you do that, make sure to create a System Restore point first.

MS Edge, autoplay video blocking coming
Microsoft Edge may be about to win a lot of fans by introducing a new feature that it says could prevent one of the most annoying things about being online. A new update to the browser suggests it is looking at a way to block auto-playing videos by default when a user navigates to a website. People spotted a new entry to the Microsoft Edge Canary browser where the company tries out its in-progress updates, that suggests auto-playing videos may have had their day at last. The new addition, for Mac, Windows, and Linux systems, is called “Autoplay Limit Default Setting”, with the description suggesting that Microsoft Edge would set the media autoplay setting to "Limit" as a default - stopping videos from starting up when a user lands on a website. Currently, Edge offers two options for users to control media autoplay - "Allow" (the current default setting), where all videos on a website will play automatically with sound, and "Limit", where media won’t be autoplayed on sites that a user has previously visited. It appears that Microsoft is looking to test the feature in Canary before rolling it out to a wider user base - as blocking autoplaying videos can cause issues for some websites. The same Canary entry also hints at a future "Block" option, which would presumably stop any videos or media from playing when a user lands on a website. However, this feature, which is also listed as being available for Mac, Windows, and Linux systems, doesn't appear to be enabled as yet.
