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, high CPU usage of 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.

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:WindowsLogsCBS 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.

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 afterwards 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.

If you have recently installed some programs in 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.
