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

If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc. Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.

Option 1 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

Error Code 0x80070017 is an error code that is most often associated with Windows 10 installations, although it has also been encountered by users on previous versions of the Windows operating systems. It is usually encountered as users attempt to install a new version of the software on their machine.

Common symptoms include:

• A vague error message regarding the inability of the system to copy over the necessary files pops up as users attempt to install a new version of the Windows operating system on their computer

While it can be hard to tell what the exact cause of Error Code 0x80070017 is on your specific device, the good news is that there are two primary methods that can be used to fix the problem and to allow you to proceed with your installation. These two methods do require some degree of technical knowledge and/or skill, so if you don’t feel like you have the ability to undertake them on your own, be sure to get in touch with a trusted computer repair professional to assist you.

Solution

Error Causes

The most basic cause of Error Code 0x80070017 is that some of the files that are needed by the system to complete the installation are either not being found by the computer or are believed to be corrupted by the system. When this happens, security features within the software prevent it from completing the installation process, so as to avoid damage to the computer. Error Code 0x80070017 can be disruptive to your installation process, but there are two basic methods that can be employed to resolve it.

Further Information and Manual Repair

While it can be frustrating to encounter Error Code 0x80070017 on your Windows machine, there are two methods that can be used to try to resolve the problem. One of these methods is extremely simple, even for the most basic users, while the second method takes a little bit more skill and technical knowledge. If you aren’t able to complete these methods on your own, be sure to get in touch with a qualified computer repair technician that can assist you. Here are the best ways to attempt to resolve Error Code 0x80070017 on your device:

Method One:  Clean Your Physical Disk

If you purchased a physical disk version of the installation files for your Windows operating system, remove the disk from your drive and clean it using a microfiber or other lint-free cleaning cloth. As you wipe down the disk, do not use any chemicals, and be sure to wipe gently from the center towards the outside edge rather than the other direction, as failure to do so can damage the disk irreparably.

In some cases, you may need to contact Windows support if you believe that there is an error on the disk itself, such as a scratch, that would prevent the disk from being used as needed in the installation process. They may be able to offer you a replacement disk or you may be able to download a digital copy of the version that you are attempting to install on your machine.

Method Two:  Use the Chkdsk Utility

To determine if there may be an error within the disk drive itself, place the installation disk into the drive and restart the system. Go through the prompts until you see the option to “repair your computer.” Choose the operating system that you are using, go into the menu for System Recovery, and type in the words “Chkdsk/r” to begin to use the tool.

Whenever you run a tool like Chkdsk on your computer, it is important to restart your machine afterward to ensure that any changes that have been made are able to be fully applied and accepted by the operating system that you are running.

Method Three: Use An Automated Tool

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.
