[Windows] About the solution when Windows Update fails due to 0x800f0825 error

Windows

Hello!This time, I would like to summarize what to do when 0x800f0825 occurs due to a Windows Update error.

Event

When Windows Update is performed, "0x800f0825" may be recorded as an error code in the Windows Update item of the event viewer or "Settings".

In this state, no matter how many times you run the update, it cannot be applied.

Also, on the OS where this situation occurs, the start menu may not open or certain store apps may not be able to start.

Cause

In this case, it seems that the cause is mainly that the files related to the OS and updates are corrupted.

In Windows Update, new features are added or old features are abolished, and installation / uninstallation is performed, and it seems that the installation failed because the file was corrupted at that time.

Solution

OS repair using DISM

First of all, as described in the MS error code table above, I think it is better to perform a DISM repair.

Not only RestoreHealth but also ComponentCleanup is often effective, so it is recommended to execute it together.

Similarly, it is better to use the repair command "sfc" and the disk repair command "chkdsk" together.

chkdsk / f sfc / scannow DISM / Online / Cleanup-image / StartComponentCleanup DISM / Online / Cleanup-image / RestoreHealth

* The same error may be displayed when the hard disk is physically damaged.In that case, chkdsk may accelerate the symptoms, so please use it according to the situation.It is a prerequisite that no hardware failure has occurred.

I will explain these tools in another article, so please refer to them if you like.

Repair with troubleshooting tools

Automatic repair with a troubleshooting tool is also effective.
The cases I have encountered have been resolved quite often.

In most cases, the old function is damaged, and it seems that it has been fixed by repairing it.

This article also explains how to use it.

Microsoft Store reset

This error may occur if a store application that cannot be used due to an OS update is included.

In some cases, resetting the store and then re-running will successfully update the store app and make it applicable.

To reset the store, try using the following command.

wsreset

More detailed reset method is summarized in this article.
Please refer to it if you like.

Clear Software Distribution and catroot2 folders

In some cases, it will fail if there is extra information left in the SoftwareDistribution and catroot2 folders.

Software Distribution is a temporary file of Windows Update, and the cartoot2 folder contains the signature of the package.

It seems that if these files become corrupted, they will not be able to continue and will fail.

Both will be regenerated when you delete the contents, which may help eliminate the corruption.

■ Software Distribution path% windir% \ SoftwareDistribution ■ catroot2 path% windir% \ system32 \ catroot2

It may be successful to remove these contents and perform the update after a reboot.

Repair by OS overwrite

The last is the usual repair by overwriting the OS.
It's a powerful repair, but it's a hassle.

If you have time to spare, you will be a candidate, so it may be a good idea to try it as a last resort.

Please refer to here for OS overwrite.

Afterword

This time, I introduced how to solve the "0x800f0825" error.

Personally, I have applied the function update program several times ... In other words, I have the impression that I often see this error on a PC that has been running for a long time.

After all, the longer you use it, the more problematic files you will accumulate.It is difficult to maintain the health of the OS.

In most cases, the troubleshooting tool's automatic repair is the solution.Is it a hard disk logic error next?

There are various causes, but I think it is rare that it cannot be fixed, so please try to repair it.

I hope it helps you.
