Reddit is one of the most popular websites in the world and how Microsoft is opening doors to everyone in its new store Reddit took a logical step and made a Progressive web application and placed it in it. Being a Progressive web app makes it more familiar and feels like a home experience using it for a lot of Reddit users. Reddit itself has a large community and active topics discussions all the time about anything. Bringing it to Windows as an application is, in my opinion, a great move since as an application it is independent, more light-weighted, and offering some other advantages specifically tied to being a standalone windows application. Everyone familiar with and using the Reddit website will feel right at home in this app and you can start using it right away.

The Makecab.exe process that’s running on your Windows 10 computer is a program that compresses the Component-Based Servicing log or CBS log files and they can get really huge if they’re not compressed. As a result, it would utilize important space on your operating system although makecab.exe does not consume high CPU resources in doing so. However, there are times when it recreates thousands of instances of itself and could cause overconsumption of system resources which slows down your computer. So when the makecab.exe process causes high CPU usage in your system, this could mean that there is a failed Windows Update. In addition, the high CPU usage of the makecab.exe process could also mean that your computer is infected with a virus or malware. Whichever the case is, you can check out several possible solutions that are given in this post to resolve the problem.

Option 1 – Try to delete log file using File Explorer

The CBS log files could reach up to 20GB size and so if you delete them, it would help in saving space in your computer and since they’re not much of use, deleting them won’t negatively affect the system at all. To delete the CBS log files, all you have to do is open the File Explorer and then go to C:/Windows/Logs/CBS and from there, open the CBS log files and delete them all. Doing so should ease the load in the makecab.exe process since it no longer has to compress the CBS log files. As a result, the process would be more relaxed. After that, you can restart your computer and check if the problem’s now fixed.

Option 2 – Try deleting the log file via Command Prompt

You can also try to delete the log files using an elevated Command Prompt. Refer to these steps to do so:

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• Next, type the following command and hit Enter to execute it:

del /f %windir%logscbs*.log

• Restart your computer afterward once the command has been executed. This should end the high disk usage by makecab.exe, if not, proceed to the next given options below.

Option 3 – Uninstall any suspicious programs you’ve installed recently

If you have recently installed some programs on your Windows 10 computer, and since then you’ve experienced high CPU usage brought on by makecab.exe, then you might want to uninstall those programs.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the suspicious programs you’ve installed, select them and then click on Uninstall to remove them.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 4 – Try running Disk Cleanup

You might want to run the Disk Cleanup utility as it is a useful tool that could delete temporary and useless files on your computer.

• Tap the Win + R keys to open the Run dialog box and then type “cleanmgr” in the field and hit Enter to open the Disk Cleanup window.
• After that, select the drive you want to clean.
• Now click OK to clean the disk and restart your computer.

Option 5 – Try to run System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files and missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your PC.

Option 6 – Try scanning your computer using Windows Defender

As mentioned, the high CPU usage of makecab.exe might be caused by some malware or virus in the system and so to eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.

Error Code 0xC004F00F – What is It?

Error Code 0xC004F00F can appear during the Windows 10 installation and activation process. It is a fairly straightforward error code that occurs when a product key is entered in that is unable to be used to complete the final activation of the new operating system. This error code is most commonly related to the installation of new pieces of hardware on a machine that was already running Windows 10 at a previous time.

Error Code 0xC004F00F can also appear on other versions of the Windows software, so if you are not specifically trying to install and activate Windows 10 when this message appears, you may want to contact a qualified Windows technician to help resolve your system error, as the error code has different causes and resolution methods on other versions of the Windows operating system.

Solution

Error Causes

In some cases, Error Code 0xC004F00F will show up if you are attempting to install Windows 10 on a computer in which the hard drive has been replaced or significantly altered. It can also appear when other major pieces of hardware, like the motherboard, have been changed out.  These pieces may be changed as part of an upgrade to new or better hardware or be changed due to the malfunction of the original pieces of equipment. Because it may appear to the Windows activation servers that you are attempting to use the same product code that you have used before to activate what appears to be a new machine (even if the machine is the same one, just with some new parts), you may see Error Code 0xC004F00F arise.

Error Code 0xC004F00F can also come up if you have installed Windows 10 on your machine in the past and have already used the product key that you are attempting to use again.

Further Information and Manual Repair

Error Code 0xC004F00F most commonly appears for users who have made major hardware or software changes done on their machine. Because this error specifically arises from the Windows activation servers believing that your computer is a new one, you’ll need to get in touch with the Windows support team in order to resolve the error. From their database, they will be able to confirm that you are not using a new computer and will be able to bypass the error, allowing you to complete the Windows 10 Activation process.

If you haven’t installed or replaced any of the hardware on the computer, but are still seeing Error Code 0xC004F00F arise during your Windows 10 installation, you will still need to get in touch with the Windows support team to bypass the error code.

Calling the Windows' Support Team

When you call into the Windows support team, you’ll want to specifically have a list of the following information readily available: Which pieces of hardware have been changed out on your computer prior to the installation and activation, what method you were using to install Windows 10, which version of Windows 10 that you were attempting to install, whether it was a single-use or multiple-use license, and basic details about your PC like its make, model, and age.  You may also want to have the product key that you were attempting to use when Error Code 0xC004F00F first appeared.

By having all of this information ready and on hand ahead of time, you’ll have a greater likelihood that your error will be able to be resolved quickly and efficiently, avoiding long periods spent on the phone with customer service. Make sure that you specifically mention that you are experiencing Error Code 0xC004F00F during the Windows 10 activation process when you call into the Windows support team so that you can be connected to a representative who is equipped to help you resolve this specific problem.
