How to Fix Error Code 0xC004C020

A few days ago we celebrated fixing of months-long PrintNightmare vulnerability by Microsoft, sadly a new bug and issue have been found. Firstly discovered Microsoft stated:

A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

A few days ago, Microsoft officially released a patch that was supposed to finally fix it. As you might recall this vulnerability was present for quite some time, Microsoft's solution after a long struggle was to elevate certain privileges to administrator account only and remove user accounts from managing printers. It complicated things a little bit but it was stated payoff was worth it. The new issue now is that on a system that already had accounts created and set, old accounts still can hijack the system, patch issues address only accounts that are created after the fix is administrated, old ones can still do whatever they want. Once again of course Microsoft has stated that until it is again resolved you should again disable the Print Spooler service as a temporary workaround.

One of the most sophisticated Artificial Intelligence or AI assistants there is in the market is Cortana. However, no matter how sophisticated this AI assistant may be, there are still times when you encounter issues with it. So if your Cortana is not connecting to the internet, worry not for this post will guide you in fixing the problem. This connection issue in Cortana might have something to do with the settings, network connectivity, or your Microsoft account. In addition, it could also be that the Firewall or antivirus program interferes with its connection. Whichever the case is, here are some possible solutions that could help you resolve the problem.

Option 1 – Try to power cycle the modem, router, and computer

• Connect the modem, router, and the PC hard-wired and then switch all of these three devices off.
• Turn on the modem and wait for 30 seconds.
• Turn on the router and wait for 30 seconds as well.
• Finally, turn on the computer and check if you can now successfully connect to the internet.

Option 2 – Check if your router or ISP is properly working

Since the basis for this issue is that Cortana is not connecting to the internet even though you are able to access websites using your browser, you might want to check your router or ISP (Internet Service Provider) and see if they’re functioning properly.

Option 3 – Try changing your internet connection

You can also try changing your internet connection and see if it fixes the problem. If you are using Ethernet, you can try connecting to a Wi-Fi connection and see if Cortana is able to connect or not.

Option 4 – Try to run the Search and Indexing troubleshooter

You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for Cortana are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Note: You can also run the Network Troubleshooter as it can also help in resolving the issue especially if the problem is in the network.

Option 5 – Try to remove Proxy

Removing the Proxy might also help you in fixing the connection issue in Cortana. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 6 – Verify your Microsoft account

In some cases, Cortana might not be able to connect to the internet because your Microsoft account is no longer verified. This usually happens when you use a two-step authentication system with your Microsoft account. To verify it, just open Settings and click on Accounts. After that, check if you have a Verify hyperlink under your Microsoft account or not then click on Verify. Afterward, follow the next on-screen prompts to verify your Microsoft account. Once your account is verified, restart your computer.

Option 7 – Try resetting Cortana

• Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
• Restart your PC.
• After your computer boots, launch Cortana again and check.

Option 8 – Try to reinstall Cortana

If none of the options given above works, you must consider reinstalling Cortana.

• First, right-click on the Start button and click on the Windows Powershell (Admin) option from the list.
• Next, type the following command and hit Enter to execute it:

Get-AppXPackage -Name Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

• Restart your computer and check if Cortana is now able to connect.

As you know, Windows operating system comes with tons of features. Some of which are not intended to be used by normal customers or users directly which means that only a small percentage of the huge user base of the operating system leverages the use of such features. However, they’ve added some major value to the feature list of the operating system. You can find these features under the “Turn Windows Features on and off” option. This indicates that if you want to, you can just type in “Turn Windows Features on and off” in the search box and then enable any feature that you want to enable. Aside from that, there are other ways you can disable or enable the optional Windows Features in your Windows 10 computer.

Option 1 – via Control Panel

• Open Control Panel and select Uninstall a Program.
• After that, select the “Turn Windows features On or Off” option on the left side.

Option 2 – via Command Prompt

• Tap the Win + X combination on your keyboard or right-click on the Start button and then click on Command Prompt (Admin). Alternatively, you can also type “cmd” in the Cortana search box and right-click on the Command Prompt icon, and select the “Run as administrator” option.
• If a User Account Control or UAC prompt appears, click on Yes.
• Next, type in the following command to see the list of the available features.

DISM /online /get-features /format:table | more

• Now all you have to do is copy the name of the feature that you want to enable and for you to do that, you need to execute the following command:

DISM /online /enable-feature /featurename:[Enter the name of the feature here] –All

Note: Now if you want to disable a feature that’s already enabled in your computer, refer to these sub-steps:

• First, you need to check what features are enabled, and for you to find out, enter this command: DISM /online /get-features /format:table | find “Enabled" | more
• And if you want to check the detailed information about a particular feature, you can enter this command: DISM /online /get-featureinfo/featurename:[Enter the name of the feature here]

Option 3 – via Windows Powershell

As you know, the Windows Powershell is a very important tool in Windows 10, and a powerful one at that since you can do a lot of things using this command line. So while you use this tool you need to populate the list of available features first and then you have to download the feature your desired feature.

• Search for PowerShell in the Cortana search box and then run it with administrator privileges.
• Next, type in the following command to populate the list of available features:

Get-WindowsOptionalFeature –Online

• After that, enter the following command to install any feature you want to enable from the list of available features:

Get-WindowsOptionalFeature -Online -FeatureName *Type feature name*

• Now enter the following command to enable your desired feature:

Enable-WindowsOptionalFeature -Online -FeatureName “Type feature name” –all

• And if you want to disable any enabled feature, just enter the following command:

Disable-WindowsOptionalFeature -Online -FeatureName “Type feature name”

Option 4 – via an external installation source

You also have the option to fetch the latest features from an updated offline source. The source could be an ISO any other type of image or just a folder. So you need to decide if you want to use Windows Powershell or Command Prompt.

• If you want to use Command Prompt, just enter this command: exe /online /enable-feature /featurename:< /All /Source:<Enter the path of the feature here>
• If you want to use Windows Powershell, use this command: Install-WindowsFeature –Source “<Enter the path of the feature here>”

Note: If you want to get the latest features, you need to get the latest version of the image of the operating system that you are trying to install the feature from.

Brave browser has gained popularity very rapidly and many websites have gone into the territory of recommending it. Sadly although the browser kind of offered better performance, it seems that so much advertised privacy and security was a lie. Several months ago, Brave was involved in a “scandal”. Unfortunately, this incident did not get much media attention, and it’s hard to search for and discover as of today. There is an article on the Android police website explaining this issue in detail, you can check it here: https://www.androidpolice.com/2020/06/07/brave-browser-caught-adding-its-own-referral-codes-to-some-cryptcurrency-trading-sites/ But to sum things up and keep them short if you do not want to go through the full article, Brave had been injecting their affiliate codes into popular crypto-currency websites. This means that they had been intercepting your traffic, which they promised was secure by the way, and modifying it. This means Brave Software has access to all of your information on those crypto-currency sites as well. They can see your payments/purchases, and your activity on the websites (through affiliate statistics). Now some people might point out that they are not interested in crypto or have been visiting some of the sites but the issue still remains and that is they did all of this, without telling the user. They intentionally didn’t tell the user because they knew it would cause backlash and disruption. They knew one hundred percent what they were doing, and they knew it was unethical. And the point remains if something like this was already done, who knows what will come up in the future. Personal recommendation is to avoid Brave and go back to other browsers.

Things have stirred lately with Chinas ban on crypto mining and many used GPUs will flow the market probably. But should you buy a used GPU? Short answer: NO, long answer: keep on reading to find out why.

GPU shortage and its cause

As you all know by now, we live sadly in a world struck by a global Pandemic. Due to this awful disease and measures taken against it, many people are either working from home or are at home making the manufacturing of new chips problematic while demand on the market has raised. Throw into that mix crypto mining which has raised in popularity and you have, well today's market where we have GPU shortage. Now with the latest news that China has banned the mining of cryptocurrency, there is to be expected that at some point in time mining cards used there will fit the market in the whole world. Sadly even with a large quantity of GPUs that will become available, the overall price of cards will not be much lowered I am afraid since demand is still very high and many people would not want to purchase used mining cards and neither should you.

Be prepared for the worst scenario

Although this sounds very pessimistic and in most cases, it will not turn out to be true, you should always prepare yourself mentally that you might be in that lower percentage that will end up with a really bad GPU. What has come up to be absolutely true when considering GPU that were mining is that if anything at all can be done to GPU in order to increase performance, it has been done. Miners want to optimize and almost every GPU if could be overclocked, it was overclocked. Extensive mining also means that thermal paste has been dried and it is pretty useless at this point and there is a very high chance that fans and heat sinks will need much cleaning or even replacement raising the price of the card itself for mentioned paste, fans, and heat sinks. There's no way to tell what the previous owner might have done with a graphics card when you're shopping online, so our advice is to assume the worst. Don't trust the seller to give truthful information. Any listing that says it was "never used for mining" at this point is probably a lie.

Age of the GPU matters

Date when GPU itself has manufactured really matters. Newer cards even if used extensively have been used for a much shorter period of time and are not so damaged were ones produced a few years ago have seen a lot of action. Let’s say that you get RTX 3060, In the worst-case scenario it has been mining since late February of 2021 and basically, it is still under warranty so it should behave OK and put some good work in gaming even in that state. On another hand, if we take for example GTX 1080Ti which is 4 years old GPU things start to change drastically. 4 years GPU could be worn out even if it was used just for extensive gaming sessions let alone for mining.

No return policy and seller rating

Most of the time you will run into a product that cannot be returned or no refunds policy. This should bring a red flag right away and deter you from purchase. Sellers with the highest ratings are more trustworthy since many of them will not want to destroy their reputation but these will probably not even have these kinds of merchandise in their store. Buying with a poor rating seller and no return policy on a product is just asking for trouble. And although some stores do have arbitration and will stand on the customer side there is no guarantee for that and it will take too much time to process.

If you really must buy a second-hand GPU

Of course in these troubled times sometimes due to malfunction or any other reason, there would not be another choice than to buy a second-hand GPU. In this case, if there is no other option consider sellers with many positive ratings. If you can buy locally that would even be better or the best-case scenario would be if you could visually see and inspect GPU itself in order to see in what state it is. Look for warranty stickers to see if they are thorn and the card has been tampered with. Also take a good look at screws, if they have scratches card has been opened, probably to replace fan or heating sinks which means that it has worked a lot.

Conclusion

It is very difficult to give the best possible advice on this situation since of GPU shortage, but I would much prefer a new GPU with lower performance than a hi-performance one which was mining.

When clean Windows is installed or when you place new hardware in your computer usually Windows itself detects the device and installs its driver. The question that comes now is, do you keep that driver or do you install the manufacturer's one. In order to answer this question let's analyze what is difference between the two drivers and other factors which could influence your decision.

Difference between drivers

First of all, know that drivers Windows installs are also drivers from the device manufacturer which have gone through Microsoft quality control in order to be included in Windows itself. Now naturally question which occurs, what is the difference, well answer to that would be this: in Windows, you have stripped down driver, just a driver in order for Windows to know what device is plugged and how to use it, meaning that for example if you install printer device, you will be able to print documents and Windows will know it is a printer but ... You will not get the control panel for that printer where you can adjust the printer itself and all of its features like let's say paperweight, etc. So if you need these kinds of features in that case it would be better to install a complete driver suite from the manufacturer and get the whole package. Windows will recognize the RAZER mouse for example but you will not be able to change its colors of program custom buttons on it until you install RAZER drivers. One more important thing to note is that drivers which are in Windows are less updated than drivers from the manufacturer's site. That being said, if you prefer and want to have the latest drivers you will prefer to get them again from the manufacturer.

Conclusion

So it seems that manufacturer's drivers are always in some form of advantage and that you will always want them and most of the time this is true, as a matter of fact, the only time I could think that you could use bare down Windows drivers is when new drivers update breaks something in Windows and device start behaving improperly. in this particular case, it is better to roll back to the previous Windows driver which has passed Microsoft quality control and is working for sure. In any other case, you are better off with the latest manufacturers drivers If you would like to read more helpful articles and tips about various software and hardware visit errortools.com daily.
