How To Fix Error Code 800B0100 8 failed windows updates

TIP: You should click here to fix Windows errors and optimize system speed.

A mistake or inaccuracy, an error is caused about by committing miscalculations on the things that you do. It is a state of having a wrong judgement or conception in your conduct that allows catastrophic things to happen. In machines, error is a way to measure the difference between the observed value or the computed value of an event against its real value.

It is a deviation from correctness and accuracy. When errors occur, machines crash, computers freeze and softwares stop working. Errors are mostly unintentional events to happen. Most of the time, errors are a result of poor management and preparation.

Seeing an error when you work on your computer is not an instant cause of panic. It is not unusual for a computer to encounter problems but it is also not a reason to let it be and not to investigate on the errors. Windows errors are issues that can be fixed through solutions depending on what may have caused them in the first place. Some may only need a quick fix of re-installation of the system while others may require in-depth technical assistance. It is crucial to react to the signals on your screen and investigate the problem before trying to fix it.

Having a sign that tells us of issues that we need to solve in life for us to move forward is a great idea. While it does not always work in life, it does in computers. Messages that indicate the issues your computer encounters are called error codes. They appear whenever there is a problem such as incorrect data input or faulty hardware. Computer programmers add predefined error codes and messages in their system codes so whenever there is an issue, it prompts the users. While error codes may be predefined, there are different sets of error codes with different meanings for other kinds of computer programs.

A lot of users experience difficulties in installing Windows software updates. Most of the time, the update error message doesn’t tell you anything helpful to fix the issue. One the most common update error is “Windows could not search for new updates” plus an error code “80240442”. Updates are important as they deliver hotfixes, security patches and other improvements. Therefore, it is vital to install them when they are available.

Microsoft has streamlined the update process in the recent versions of Windows. However, this does not mean that update errors are totally out of the picture especially with issues relating to compatibility.

What causes Error Code 800B0100 8 failed windows updates

Whenever you see windows error on your screen, the easiest and safest way to fix it is to reboot your computer. Just like our bodies needing a shut eye for several minutes, our computers also need to shut down once in awhile. A quick reboot can refresh your programs and gives your computer a clean slate to start a new venture. More often than not, it also eliminates the errors you have encountered after rebooting. It is also ideal to shut down your computer once a week to completely put all unused programs to rest. However, when a reboot does not work anymore, use more advanced Windows solutions to fix your errors.

It is important to always run a system diagnostic scan when Windows Updates fail to download or install in order to pinpoint the root cause of the problem. Microsoft provides a troubleshooter for Windows Update related errors that will detect the problem and most likely can automatically fix it. However, there are always these type of errors that are hard to pin down.

Here are some steps to help you troubleshoot the problem and fix it.

  1. Clear up your Temporary Files and Internet Cache and reboot.
  2. Disable your Firewall and Anti-virus software.
  3. Use the Microsoft’s Windows Update Troubleshooter to reset Windows Updates settings to defaults.
  4. Flush the Software Distribution Folder.
  5. Reset the Catroot folder.
  6. Boot in Clean Boot State and run Windows Update again.

Windows error: Code 800B0100

You can take a look at this page: Code 800B0100 : Windows Update encountered an unknown error. My CBS folder is 90 MB big and I tried to upload it in 4 8MB compressed winRAR parts but I somehow couldn't upload it so I just uploaded the txtfiles in it I hope this is acceptable. If there is anything else you want to know or want me to upload please let me know.

And this one: Troubleshoot problems with installing updates - Windows Help

I read that this can also be caused by a NOT genuine copy of windows?

Let me know if they are needed.

The one exception is for security definition updates - those go through fine. Based on this guide I've rerun SURT and SFC, but to no avail.

Ive taken them all out in this zip file. Note: the log directory had several persist log files that were over 20GB all together. Before I found this site I've tried system update readiness tool, check disk, Windows Update Troubeshooter, DISM, and sfc, none have helped so far.

Whenever I do any windows update I get error 800B0100.

I've attached the log directory which will hopefully help.
