Fix Office Activation error 0x80070426

Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working. When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below. Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:

• %userprofile%Desktopsfcdetails.txt
• Log %WinDir%LogsCBSCBS.log

Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file. Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter. Step 4: After opening Command Prompt, type and enter the command below to execute it:

takeown /f FileNameAndPath

Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll” Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again. Step 6: In the elevated Command Prompt, type and enter the following command to execute it:

icacls FileNameAndPath /GRANT ADMINISTRATORS:F

Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”. Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:

copy NewFileLocation FileNameAndPath

Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”

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”.

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.

The setup process will eventually pick up exactly where it left off. The only difference is that there is no connection to the internet and your screen will no longer be stuck on the PIN setup screen so you now have the option to skip it and wait until you’re logged in for the first time. Step 3: Once you’re done, you can then you can choose to Setup Pin later on and turn your internet connection back on or connect your computer with an internet connection.

If you suddenly encounter a Blue Screen error that points out to either the mfewfpk.sys and epfwwfp.sys files, then this post might help. Both of these files are created by third-party software. The mfewfpk.sys file is created by the McAfee security software while the epfwwfp.sys is created by the ESET Antivirus. These files are residual files and sometimes it blocks upgrading Windows 10. Aside from blocking Windows 10 upgrade/update, these files can also cause a Blue Screen error after an upgrade which leaves your Windows 10 computer useless. When you get a Blue Screen error caused by any of these files, you will see an accompanying error message that states, “DRIVER IRQL NOT LESS OR EQUAL”. To fix this Blue Screen error, you can check out the suggestions laid out below but before you do that, you need to create a System Restore point first as it can help you undo any unwanted changes. In addition, make sure to also boot your computer into Safe Mode with Networking before you troubleshoot.

If your WIFI signal is strong but you can not connect to the internet then keep reading in order to find out why this happens and what can you do to fix it. One very important thing to know and understand is that WIFI and the internet are two different things and that they altho connected and working together are basically 2 things. WIFI is a name for a group of technologies that are using radio vawes to connect to the router in order to access the internet. The Internet itself is series of computers all connected in LAN. Think of WIFI like some invisible cable that connects your computer to the router. When we put things into perspective this way it becomes clear that we can indeed have a strong WIFI signal and that we are connected to the router but the router itself is not connected to the internet. So basically troubleshooting an internet connection is troubleshooting the router itself. The most common approach is to reset the router, turn it off, then back on, check cables, etc. But be sure that if your WIFI signal is strong and you can not access the internet it is a router issue.

The latest update from Panos Panay on Twitter is including New and redesigned Snipping tool inside Windows 11. From the shared video, we can see that it includes modern Windows 11 UI redesign and it looks and feels like a part of Windows 11. More things that can be seen from the shared video is that it looks like the new snipping tool is a merged version of the old with snip & sketch. It is good to see that it is still possible to capture screen with easier way natively inside Windows 11 but some more functionality would be more welcome I guess. Users were asking for added functions for a long time like adding simple text for example but from shared video, no new features were presented so for some users 3^rd party solutions will still be the way to go. The new and redesigned Snipping tool will roll out with the next update and we will see then about all new features inside it firsthand. Until then, take care.

FlightSearchApp is a browser extension for Google Chrome. This extension claims to be a simple tool to provide updates regarding flight arrivals, flight departures, flight tracking, and access to time zone converters. However, it is a potentially unwanted program which is also known as a browser hijacker.

This extension hijacks your browser home page and search engine changing it to MyWay. While this extension is active you will see additional ads, sponsored links, and sometimes even pop-up ads appearing through your browsing sessions. It also keeps track of your browsing data, recording your browsing activity, website visits, clicks, and potentially personal information. It also adds a toolbar to the browser header which can lag the browser while also reducing usable screen size.

Several anti-virus scanners have marked this extension as a Browser Hijacker, and is therefore not recommended to keep on your computer.

About Browser Hijackers

Browser hijacking is regarded as the internet’s constant risk that targets web browsers. It is a kind of malicious software that alters your web browser’s configuration settings so that you are redirected to websites or webpages that you had no intention of visiting. Basically, nearly all browser hijackers are made for marketing or advertising purposes. The idea would be to force users to visit particular websites which are looking to improve their visitor traffic and produce higher ad earnings. It might appear naive, but the majority of such sites are not legitimate and will pose a serious threat to your on-line safety.

How it infects your PC

Browser hijackers can get into a computer by some means or other, for instance via file sharing, downloads, and email too. They are generally included with toolbars, add-ons, BHO, plugins or browser extensions. Some browser hijackers spread in user’s computer systems using a deceptive software distribution technique known as “bundling” (usually through freeware and shareware). Browser hijackers may record user keystrokes to collect potentially valuable information that leads to privacy issues, cause instability on computers, significantly disrupt user’s browsing experience, and finally slow down the computer to a point where it will become unusable.

Browser hijacker removal tips
