Fixing Windows Update Error 80244019

Hello everyone, I hope you are all doing well. Today we will be changing the Windows Lock Screen background. Changing the lock screen background is a very easy task and it can be done in a very short time. So let's jump right into it. The first thing you need to do is to press the Windows start button on the bottom left and then press settings. Once the settings screen appears, choose and click on Personalization. Inside personalization, click on the Lock Screen tab. On the right screen, under the picture, you will find Windows spotlight, click on it to bring a drop-down menu up. Your choice is presented as a single picture for background or slideshow, a series of pictures that are going to be looped in a given time interval. If you would like just a single picture for your background, choose that and click on it. Once you are in choose picture dialog, click on the browse button and navigate to the picture on your storage which you would like to have as a background. If however, you fancy slideshow as your lock screen background, click on the background drop-down menu and choose the slideshow. Next, click on add a folder and navigate to a folder where you have pictures that you would like to have as a slideshow for your Windows lock screen.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

As you know, just like other web browsers, Google Chrome offers Incognito Mode or private browsing which you can use to make sure that your browsing activities are not being tracked by any websites you visit and it also keeps targeted ads at bay. On the other hand, signing in to a website, even when in Incognito Mode is a different thing since that website can track your browsing activities. Thus, Incognito Mode is still useful especially if you want to browse the web safely and without getting tracked except when you log in to some site. However, there have been reports recently that Incognito Mode is missing in Chrome and users are clueless as to how or why it happened. If you are one of them, worry not for this post will walk you through what you can do if there’s no Incognito Mode in Chrome on your Windows 10 computer. This is an unusual and strange issue since the Incognito Mode in Chrome is available by default and you don’t have to do anything to enable it. It is possible that there might be corruption in the Windows Registry which caused the disappearance of Incognito Mode, worry not though for there are some tweaks you can apply to restore the missing Incognito Mode. To apply these tweaks, you need to create first a System Restore point, and then once you’re done, follow the instructions provided below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor. Step_2: Next, after opening the Registry Editor, navigate to this path – ComputerHKEY_LOCAL_MACHINESOFTWAREPolicies Step_3: From there, look for ChromePolicies and locate the DWORD named “IncognitoModeAvailability” and double click on it. Step_4: Edit the value of the “IncognitoModeAvailability” DWORD by changing its value from 1 to 0 so you can enable Incognito Mode in Chrome. Step_5: Once done, exit the Registry Editor and restart your computer and then check if you can now see Incognito Mode in Chrome. On the other hand, there is also another option that allows you to force open your Chrome browser in Incognito Mode. All you have to do is set the value of the “IncognitoModeAvailability” key to “2” instead of 0. This can be useful especially if you always browse the web in this mode. But you need to remember that you won’t be able to go back to the normal mode once you do this. Here are what the values of the IncognitoModeAvailability DWORD actually mean:

• 0 – Incognito mode is enabled by default
• 1 – Incognito mode is disabled
• 2 – Chrome is forced to always open in Incognito mode

While browsing the internet, if you suddenly encounter a warning with an error message saying, “Server certificate has been revoked ERR CERT REVOKED” then it indicates that the SSL certificate used by the website has been revoked by its issuer. This kind of problem can only be fixed by the website owner but that does not mean that you can’t do anything about it. In fact, you have the option to bypass this error as well as contact the certificate issuer – all this and more. Just a reminder, if a website that accepts payment, its passwords don’t have SSL or has some certification issue, you should never trust it. For instance, if you are trying to purchase something online and you’re on the payment stage but you encounter the “Server certificate has been revoked ERR CERT REVOKED” error, you must not proceed. To resolve the “Server certificate has been revoked ERR CERT REVOKED” error, here are some things you can do.

Option 1 – Try contacting the Certificate Issuer

If you are the website owner, of course, the best thing you can is to get in touch with the Certificate Issuer in order to resolve the problem.

Option 2 – Try fixing the Date and Time

You have to check your computer’s Date and Time. There are cases when this simple setting causes a connection problem. So if your computer Date and Time is set to date or time that this after the certificate expiration date, then you have to make sure that you set it to automatically configure time. To do so, just open Settings > Time and Language. From there, turn on the toggle for “Set time automatically” and “Set time zone automatically” options. After that, check if it fixes the error, if not, you need to check if the manual selection is correctly set or not.

Option 3 – Bypass the Certificate Revocation Check

As pointed out earlier, you have the option to bypass the Certificate Revocation check. All you have to do is follow the steps below.

• In the search box of your browser, type “internet options” and open it once it appears.
• After that, go to the Advanced tab and navigate to the Security subheading.
• Next, uncheck the “Check for publisher’s certificate revocation” option as well as the “Check for server certificate revocation” option.
• Now restart your computer. Upon the next startup, try opening the website again. This time, your browser will stop checking it for certificate issues. However, it’s not safe to leave those options unchecked so make sure that once the website’s SSL certificate is fixed or once you no longer have to visit that website, you recheck those options.

Windows 10 has a lot of several useful features and one of them is the Nearby Sharing feature. You can access this feature by going to Start > Settings > System > Shared experiences. From there, switch on the Nearby Sharing option and select the folder where you want to download the files to. This feature is really useful as it allows you to share files. However, there were reports from a number of users recently stating that Nearby Sharing is not working on their Windows 10 computers. If you are one of the users facing this problem, you might want to try checking if the Windows 10 v1803 Update is installed on your computer or not. You could also try to check if Bluetooth supports low energy mode or you could also try bringing the device closer or check if the adapter has Bluetooth version 4.0 or later. For more information, refer to each one of the given options below.

Option 1 – Try checking if Windows 10 v1803 Update is installed

To check if the Windows 10 v1803 Update is installed on your computer, go to Start > Settings > System > About. From there, scroll down to the Windows specifications and check the Version. If it is 1803 or above, then the Nearby Sharing feature should be active on your computer. However, if you find that Windows 10 v1803 Update is not installed yet, then you need to update your computer to its latest version and then see if it fixes the problem or not.

Option 2 – Verify if Bluetooth supports low energy mode

Although low energy mode is not really necessary in using Nearby Sharing, there are some Bluetooth terminals that support low energy mode which makes a lot of difference. Thus, you need to check if Bluetooth in your computer supports low energy mode by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After that, expand the list of Bluetooth adapters, and then right-click on your adapter and select Properties.
• Go to the Details tab and select Bluetooth radio supports Low Energy Central Role from the drop-down menu and if its value says “<true>”, it means that your Bluetooth supports low energy mode, otherwise, it doesn’t.
• If your Bluetooth does not support low energy mode, then you might want to consider purchasing an external one.

Option 3 – Try bringing the devices closer

Nearby Sharing might not work if your devices are not close enough. Thus, you need to bring your devices closer together and see if it fixes the problem. And when you do, make sure that Network Sharing is switched on for all the concerned devices.

Option 4 – Make sure that you’re using Bluetooth version 4.0 or later

For you to use the Nearby Sharing feature, you have to make sure that the adapter for all the concerned devices is using Bluetooth version 4.0 or later. So if one of the devices or if all the devices are not using this version or later versions, then you must buy an external Bluetooth adapter for you to enjoy the Nearby Sharing feature.

If you encounter Error 0xc0000005 when you try to launch a program on your Windows 10 computer then this means that Windows was unable to process the files and the configuration correctly needed in order to run the program properly. You can encounter this kind of error with an installed program and even as the installer for a particular program. To fix this error, this post will provide you with some potential fixes that might help. Error 0xc0000005 occurs due to Access Violation which happens when a user tries to open a program and this error code may be accompanied by any of the following three error messages:

• The application was unable to start correctly

• After that, go to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWindows
• From there, double click on LoadAppInit_DLLs located at the right side of the panel and change its value from “0” to “1”.
• Now restart your computer.

Option 7 – Try checking RAM

You can also check RAM physically and see if it is in an operable condition. You might want to consider replacing it and see if it fixes the error.

Option 8 – Try to disable your antivirus program temporarily

Disabling the antivirus program or any security software installed in your computer might help in resolving the error since there is a good chance that it’s blocking the program from execution due to suspicious behavior. Just don’t forget to enable the antivirus program back again.

Option 9 – Troubleshot the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the one that’s causing Error 0xc0000005. To identify which program is causing the problem, you need to put your computer in 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”.
