How to Fix Error Code 0xC004C020

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

Restoro box imageError 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.

Device frequently disconnects from hotspot
As you know, Windows 10 comes with the option to create Mobile Hotspot for other devices. This allows you to share your Ethernet connection. However, there are times when one of your devices might fail to reconnect to the mobile hotspot again. For instance, you moved out of the Wi-Fi range because you have somewhere to be and whatnot and when you’re back you find that you are now unable to reconnect to the Windows 10 Hotspot or the shared network. Although you can always restart the mobile hotspot to resolve the problem, however, it might only be a temporary fix. So in this post, you will be given options for a much better solution to the problem. This kind of problem seems unusual and does not occur that often. To fix it, you can try to set up DNS on your Windows 10 device and then configure the settings on the mobile device. It seems that what’s happening here is that the mobile device is unable to lock on to the Mobile Hotspot when the IP address changes for some reason.

Option 1 – Try changing the DNS settings on your laptop

In this option, you need to make sure that IPv4 and IPv6 are selected on your Ethernet connection. You also have to change the Preferred DNS server as well as the Alternate DNS server to 8.8.8.8 and 8.8.4.4, respectively. You also have to validate the settings before you exit just to ensure that you’ve entered everything correctly. After that, open Command Prompt and run the ipconfig command and then take note of the IP address, Gateway DNS 1 and DNS 2.

Option 2 – Try changing the Wi-Fi settings on your mobile device

This option should be mostly the same on all your mobile devices. And given that OEMs build their customization and skin, you might have to fiddle around a little to get the settings. Refer to the steps below to change the Wi-Fi settings:
  • Go to the Settings of your mobile device and tap on Wi-Fi.
  • Then click the Mobile Hotspot connection that you’ve created on your laptop.
  • After that, input the password and tap the Advanced options.
  • From there, tap on IP settings and select the Static option instead of DHCP.
  • Now you have to enter the IP address, Gateway, DNS 1, and DNS 2 of the laptop you’ve taken note of earlier and that’s it.
Note: If you are already connected to the Mobile Hotspot, long press on the Wi-Fi network and select the Modify Network option and then follow the steps given above to change from DHCP to static. Once you’re done, your mobile device should now be able to connect to the Windows 10 Mobile Hotspot all the time.

It is no secret that a few days ago Facebook has been breach and tons of user accounts have been compromised. These kinds of things are very unpleasant experiences for both users and the company itself. User trust lowers significantly in the company and it can greatly increase the chances of users migrating to another platform. This just shows how much a hacker or security breach can produce damage to the business. Sadly we can not offer you guidance or assistance in recovering your stolen data nor can we provide you with removing your data from the hands of the attacker. What we can do is to provide you with information has your data been stolen. Threat actor released the personal information for 533,313,128 Facebook users on a hacking forum, including mobile numbers, name, gender, location, relationship status, occupation, date of birth, and email addresses. This data was originally sold in private sales after being collected in 2019 using a bug in the 'Add Friend' feature on Facebook. Facebook had closed this vulnerability soon after it was discovered, but threat actors continued to circulate the data until it was finally released practically for free. Since then, Troy Hunt has added the leaked data to his Have I Been Pwned data breach notification service to help users determine if a Facebook member's data was exposed in the leak. Go to the site and enter your email address to check and see if your data has been compromised.

Turn On/Off and Clear Windows Clipboard
Windows 10 has a Cloud Clipboard feature that allows users to have a list of multiple copied text in place so that they can reuse it. And each time the computer restarts, the Clipboard Data is cleared. However, you can actually do it manually. How? Read on as this post will walk you through how you can turn on or off as well as clear the Clipboard history in Windows 10. This kind of feature is already available in Windows 10 v1903. In the previous versions of Windows, there was no feature to turn off history in the clipboard and users have to use other ways to clear the clipboard history. And now it seems that Microsoft has put an end to this dilemma as it now allows users to clear the clipboard history. To turn on or off or clear the Clipboard history, here are some instructions you need to follow: Step 1: Tap the Win + X keys to open the power menu and select Settings. Step 2: After that, navigate to Settings > System > Clipboard. Step 3: From there, turn off the toggle button under the Clipboard history section. This will turn off the Cloud Clipboard feature. As a result, the default clipboard will hold one last item and will not display the data on the clipboard. Note: When you tap the Win + V keys to invoke the clipboard manager, you will see a prompt that says, “Can’t show history, See all copied items in place, Turn on clipboard history”. You have the option to turn it back on by simply clicking on the available button. Doing so would only hide the existing data and makes sure that no copy of the data is kept.

Conclusion

On the other hand, if you want to clear the clipboard without affecting its history data, you have to make sure to pin the items on the clipboard that you want to stay. After that, click on the three-dotted icon for the menu and click on the “clear all” option. This will delete all the entries but will keep the pinned items on your clipboard.

Shutdown your PC properly

So, you have finished with work, game, movie, music, email, or whatever on your PC, you look at the clock, it is late, you decide to go to sleep or outside, you click on the power button and choose shutdown. Now when a PC is shut down you feel good and go with your business but the next time you power it up you get the same error like the computer never really shut down in the first place. You wonder why and reboot it, just in case and all of the sudden error is gone.

If something similar has happened to you or you had the feeling that after shutting down your computer has not really felt like shutting it down, do not seek professional help, everything is OK with you because when you click on shut down, your computer does not really shut down!

Truth is that Microsoft has changed how to shut down works and how rebooting works in Windows with an update but has not publicly said anything about it so some users may experience this feeling of not shutdown phenomenon and might even think there is something wrong with their PC.

Why this change?

A few years ago shutdown button and option in Windows were really shutting down OS, but things changed when Microsoft wanted to increase boot-up speed. Now when that decision was made shutdown option was changed. So, what was changed? Well in order to increase Windows booting time, the shutdown will now turn off power to PC components and it will look like everything is indeed shutdown but the Windows kernel will actually be saved to a hard drive with all settings and just awaken once the PC is turned back ON. This will result in all errors and other stuff being just still present same as they were once the system was instructed to be turned off.

Rebooting your PC will now clear kernel and file from the hard drive and you will get a clean system startup without any issues tied with the kernel itself.

Workaround

Now that we know why and what change has been made to Windows logical question is can we shut down our PC at all properly? Luckily for us, the answer is yes and we will not need any external application to do it, we can still do it inside Windows itself and it is quite quick and easy.

Bringing back the old shutdown

In order to bring the old shutdown functionality of your PC please follow the instructions but be aware that by doing this your PC will boot a little bit slower since it will have to load the kernel from scratch each time computer is turned ON.

First thing is to go to settings and go to System

system settings

Then once you are inside the system, navigate to the power and sleep and click on it to select it. Once you have it selected to all the way to the right and click on additional power settings.

power and sleep options

When you click on advanced power settings you should be led to the control panel's power options. Inside this panel click on top left link where it says Choose what the power button does.

power options in control panel

Inside options, you will need to untick the box next to Turn on fast startup (recommended), this option has been ticked ON by the Windows update and probably without notifying you. Option means exactly what was described, it will save kernel state on the hard drive for faster boot time but sadly it can cause some issues since it will never be reloaded from 0.

If you are unable to uncheck the box click on the text beside the shield icon that says: Change settings that are currently unavailable (you will have to be logged in as administrator).

shutdown options for power buttons

Conclusion

Altho turning off fast startup and shutting down the PC completely will for sure extend your bootup time I still believe that it is the right choice since sometimes a lot of clutter and bad things accumulate over time inside the OS and can cause a vast variety of problems in a long run. So stay safe and shut down that PC as it used to be in the past.
