How to Fix Error Code 0xc0000142

Error Code 0xC004C020 (Code 0xC004C020) – What is it?

Error code 0xC004C020 (Code 0xC004C020) is an error that occurs when you attempt to activate a copy of Windows 7 with a key, but the key has already been activated multiple times. When receiving this error code, it means that you are trying to exceed the number of times that the Windows 7 key is allowed to be activated. Common symptoms include:

• Attempting to install Windows 7 with a key and a dialog box with the code 0xC004C020 is displayed.
• The computer is unable to install Windows 7 with the key.
• Certain features will refrain from working until the correct key has been entered.

Solution

Error Causes

Error Code 0xC004C020 occurs when you are not able to install Windows 7 using a previously purchased key code that has been installed numerous times previously on the same computer.

• You are not able to use your previously used key to install Windows 7.
• You have used the Windows 7 key the maximum number of times allowed.

Error code 0xC004C020 simply means that the Windows 7 code that you are trying to use to install Windows 7 has already been used the maximum number of times allowed, even when installing it on the same computer that it was previously used on. This would indicate that the key is what is known as a volume key- meaning that there is a cap on the number of uses.

Further Information and Manual Repair

Many people encounter this problem when they are doing software development or testing and need to reinstall Windows 7. Some people might also encounter this error code when installing Windows 7 with a key that was used too many times previously. It should be noted that there are several ways to fix this problem, but if nothing is working, you should contact a computer repair technician.

Method One

Activate by phone- the long method.

1. Click the start button, right-click Computer, click Properties, and then click Activate Windows.  This will open Windows Activation.
2. Click on “Show me other ways to activate”.
3. Find and enter the Windows 7 key, then click Next.
4. Click on “Use the automated phone system”. If you are prompted for an administrator password or a confirmation, confirm or type the password now.
5. Select the location nearest to you and then click the Next button.
6. There will be a list of available phone numbers, choose one and call it. There will be an automated system that will guide the activation process.
7. Enter the installation ID when prompted, it will be listed on your computer screen.
8. The phone system will give you a confirmation ID, write this down.
9. Type this confirmation ID into the space that is provided by step 3. This will be in the activation dialogue. Then, click NEXT and follow the instruction.
10. If this is not successful, stay on the line and be transferred to a customer service representative that will assist you.

Method Two

Activate by phone- this is a much simpler method.

1. Click on Start, type: slui.exe 4 into the Search box
2. Press Enter on the keyboard.
3. Pick your country.
4. Choose the Phone Activation option; stay on hold to speak with a customer service representative.

Method Three

Error code 0xC004C020 occurs if you have used your Windows 7 activation key on multiple computers, or multiple times on the same computer. You are not allowed to exceed the uses of the key—you should consider purchasing a new key if this is the case. A Windows 7 key is available for purchase online through the Microsoft website, in the shop section. The new product key must then be activated within 30 days, or it becomes no longer valid. It can be activated online or through the telephone. If it is not activated on time, features will stop working until the new key has been activated. This should be the last resort method, as you should not have to purchase a new Windows 7 key code if it is not necessary. If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

One of the most common hardware issues with any PC usually has something to do with the hard drive so if your hard drive experiences some errors, you could end up losing a lot of important information that’s stored in your computer. This is why Windows provided users with the CHKDSK utility which helps in looking for bad sectors on the drive. However, there are times when the CHKDSK utility could also face issues like the following error:

“Failed to transfer logged messages to the log event with status 50.”

According to security experts, this error is most likely due to the hard drive or RAM being in a “Read-only” state. It could also be due to some physical issues with the hard drive. On the other hand, it could be that the system is prevented from creating logs by some drive, service, or malware. To fix this error, you have to check if the hard disk is writable. You could also try to run the CHKDSK utility in Safe Mode or you could also check the physical status of your hard disk or external drive.

Option 1 – Check if the hard disk is writable

Although the CHKDSK utility checks for bad sectors in the hard drive, it also has to create logs of the result. And as states in the error message, the CHKDSK utility is not able to log the logged messages. This kind of error occurs when the log can’t be written to an installation disk. You can find the log in this location, “C:WindowsSystem32LogfilesSrtSrtTrail.txt”. Now you have to check if the drive writable by following these steps:

• Log in as administrator and right-click on the system drive.
• Select Properties and then go to the Security tab. Here, check if you are allowed to modify the drive. If not, click on Edit (as an administrator).
• Now edit the permissions for the SYSTEM and Administrators group. Note that these are the only default settings for these two groups or usernames.
• Then click on the Apply button save the changes made and exit.

Option 2 – Run the CHKDSK utility in Safe Mode

You could also try to run the CHKDSK utility in Safe Mode as this might solve the error.

• Boot your computer in Safe Mode.
• Next, open Command Prompt with admin privileges.
• Then type and enter this command to execute it: chkdsk c: /f /r
• Wait until the process is completed and boot your computer normally and then run the CHKDSK utility again and check if the “Failed to transfer logged messages to the log event with status 50” error is now fixed.

Option 3 – Try to check the hard disk or external drive physically

If the first two options didn’t work, you might want to check the physical status of your hard disk or external drive as the problem could root from there. You can try to tighten the wires that connect the hard disk to the motherboard. However, if it doesn’t help, you should seek out assistance from a hardware technician.

nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache. On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table. Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:

nslookup xyz.com Server: dns.company.com Address: 192.168.1.38 C:> ping xyz.com Ping request could not find host xyz.com. Please check the name and try again.

The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.

Option 1 – Reset Winsock, TCP/IP & Flush DNS

Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. To do so, follow these steps:

• Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
• After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.

1. netsh winsock reset – type in this command to reset Winsock
2. netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
3. ipconfig /flushdns – type in this command to flush the DNS cache

• Next, restart your PC and check if the problem’s fixed.

Option 2 – Force Windows to do a DNS lookup using FQDN

• Go to Settings > Network & Internet > Status > Change adapter options.
• From there, right-click on the network and select Properties.
• Next, in case you’re using IPv6, from the list of connections available in the list, select Internet Protocol Version 4.
• Then click on Properties and click Advanced.
• After that, switch to the DNS tab and select “Append these DNS suffixes (in order)” and click on the Add button and then add “.” as a suffix so that each time you query using PING and another tool, it will add a “.” at the end and will force the lookup.

Option 3 – Make sure that there is only one default gateway

If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.

Option 4 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Check the Windows Host file

You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.

Option 6 – Delete the WLAN Profiles

Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

Option 7 – Reinstall the Network Adapter Drivers

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and select “Uninstall device”.
• Restart your PC.

When you upgrade your Windows 7 or Windows 8.1 system to Windows 10, you’ll undergo a phase called Out of Box Experience, or simply OOBE. This phase is intended to allow users to customize their Windows 10 experience, which includes defining personal settings, creating user accounts, and more. Some users reported having issues when creating their user account during the Out of Box Experience (OOBE) on Windows 10 upgrade. Some also reported issues about non-responsive behavior (Welcome Back) page.

Solution

Error Causes

Unfortunately, there’s no known cause for this error. However, some users reported that this occurs when:

• There’s a problem with the ISO or CD used to install Windows 10
• There’s hardware malfunctioning on the computer

Further Information and Manual Repair

Your Windows 10 upgrade will not be successful if you’re not able to create a user account or finish the Out of the Box (OOBE) phase of the installation. Here are some methods that will help you fix this manually.

Method 1 – Wait and retry

Some users reported that waiting for about an hour and retrying the process again will solve this problem. It’s also recommended that you keep your computer in a ventilated place while you wait to retry the process.

Method 2 – Load default user manually

This method has 2 requirements in order to work.

1. You need to be upgrading from a previous Windows version, and
2. Your Windows was originally configured to automatically boot to desktop

If you meet these two requirements, you can solve the error by following the steps below:

1. Hold CTRL+ESC keys. Windows should load the default user after doing this step.
2. Press the Windows key + X. Then, click the Computer Management icon
3. Choose “Local Users and Groups”
4. Double click on Users
5. Right-click on the right pane, and then choose “New User”
6. Create a new user account and password

Method 3 – Power down your laptop

This method only applies if you’re a laptop user.

1. Power down your laptop
2. Remove the battery of your laptop
3. Wait for about 10 minutes
4. Connect your laptop using direct current
5. Turn on your laptop again
6. Create a new user account and log in

Method 4 – Create a local account if you’re trying to set up a Microsoft account

Instead of connecting to a Microsoft Account after the set-up, you might want to try creating a local account. To do this, follow the steps below:

1. Power down your computer if you are to set up a Local Account.
2. Disconnect your computer from the Internet, either Wired or Wireless
3. Unplug your computer, and wait for about 10 minutes.
4. Reconnect your computer and start Windows. Do NOT connect to the Internet and make sure you’re disconnected to any devices you don’t need.
5. Try creating a user account again

 If the steps above don’t work, you might want to try Startup repair.

Method 5 – Boot your computer from Windows 10 media

In order to do this step, you need to have official Windows 10 ISO files.

1. Go to the “Install Now” screen
2. Choose Repair your computer
3. Click Advanced Options
4. Click Safe Mode

After doing the steps above, there’s a chance you get an error message that says “installation cannot be completed in safe mode”. When you see this, just press Shift+F10. This will execute and open the command prompt of your computer.

 From the command prompt, you can try and create a new user account.

 For example, net user Username Password /add

 The username here should be replaced with the account name you want to add, and the Password here should be replaced with the password you want to use for the account.

 After replacing the username and password on the text, press the Enter button on your keyboard. You’ll know if the command is successful once you see the message, “The command completed successfully.”

You can now close the command prompt. Restart your computer and try to log in using the account you just created.

If all the above methods still don’t work, it might be best to try automated software to help you fix this problem.

Error Code 0xc004c008 - What is it?

This specific Windows 8.1 or Windows 10 error code has to do with the number of times you can use your license number to install windows programs on computers. All windows activation codes are licensed to be used one time for a device, to control piracy, but what happens when your PC crashes, or you have to change a hard drive component and are forced to re-install Windows Operating System. Luckily, there is an easy fix for this issue.

Solution

Error Causes

Basically, when you need to re-install the Windows operating system that you have previously bought and installed on another computer an error code will be displayed with a message telling you that the activation server determined that the specific key could not be used for activation. This occurs because the key has already been used on that computer, or a different one, to install operating systems. There are a few easy fixes for this issue, and most of them should be easily completed on your own.

Further Information and Manual Repair

There aren’t many explanatory ways to repair Error Code 0xc004c008. Below are two methods to go about addressing this issue.

Methods 1:

1. The first step is to open the “Run” Window. You can do this in two ways. First, press the “Window” key and press the “R” key simultaneously. This will open the “Run” menu. Or you can start the “run” window by going to the Start menu and selecting Run.
2. In the Run window type “SLUI 4” and click enter.
3. A Phone Activation window will open up, after which you'll need to select a few options.
4. First chose the country in which you registered the product for the first time.
5. Choose your country and a phone number will be displayed specific to your choice. You will now need to call the number provided.
6. After you’ve dialed you will be prompted to write your “Installation ID”. Type your “Installation ID” on the phone.
7. After that step, you will be asked how many copies of Windows have been installed using this license. Choose “1”, should anything else be chosen but “1”, this will not work.
8. After the process is completed, you will be given a confirmation ID and should be able to proceed as normal with installation. You will have a workable product key again.
