Windows Update Error 0x800736B3 — Fix the Component Manifest Error

What Does This Error Mean?

Windows Update error 0x800736B3 means there is a problem with the manifest (the description file) of a Windows component. Think of a manifest like a table of contents for a software component. When it is missing, damaged, or has incorrect information, Windows cannot properly install the update.

Affected Models

Windows 10
Windows 11
Windows 8.1
Windows Server

Common Causes

The Windows component store has a corrupted or missing manifest file
A previous failed update left orphaned or conflicting manifest entries
Windows system files were damaged by a sudden shutdown or power outage during an update
Disk errors caused corruption in the CBS (Component Based Servicing) data
An aggressive disk cleanup tool removed manifest files that Windows Update needs

How to Fix It

Run DISM to repair the Windows component store. Open Command Prompt as Administrator and type: DISM /Online /Cleanup-Image /RestoreHealth — wait for it to complete fully.

This is the primary fix for manifest errors. DISM downloads correct manifest data from Microsoft and rebuilds the component store. It requires an internet connection and can take 20 to 45 minutes.
After DISM completes, run the System File Checker. In the same elevated Command Prompt type: sfc /scannow

After DISM repairs the component store, sfc can use that repaired data to fix any additional corrupted files it finds.
Check the DISM log for details if errors persist. The log is at: C:\Windows\Logs\DISM\dism.log — Open it with Notepad and search for 'Error' to see what specifically failed.

The DISM log gives technical details about exactly which manifest is corrupted. This information helps a technician if further repair is needed.
Run Check Disk to look for disk errors that may have caused the corruption. Open Command Prompt as Administrator and type: chkdsk C: /f /r — type Y and restart.

Disk errors can corrupt component manifests. Fixing the disk first ensures the repair tools can write corrected files without them being immediately corrupted again.
Try the Windows Update Troubleshooter at Settings > System > Troubleshoot > Other troubleshooters > Windows Update. After running it, restart and try the update again.

The troubleshooter resets the update services and clears the download cache, which sometimes resolves manifest conflicts without needing DISM.

When to Call a Professional

This error sometimes indicates deeper corruption in the Windows component store that DISM cannot fully repair. If DISM reports errors it cannot fix, a technician can attempt an in-place Windows upgrade repair, which rebuilds the component store while preserving your files.

Frequently Asked Questions

What is a component manifest in Windows?

Every Windows component (a piece of the operating system) has a manifest file. This is an XML file that describes what the component contains, what version it is, and what other components it depends on. Windows Update reads these manifests to understand what needs to be updated and in what order. When a manifest is corrupted or missing, Windows Update gets confused and fails.

Can DISM fix all manifest errors?

DISM fixes most manifest errors by downloading replacement data from Microsoft's servers. However, if the internet connection is interrupted during the fix, or if Microsoft's servers do not have the exact data for your Windows build, DISM may report that it cannot fix all issues. In those cases, an in-place repair upgrade using a Windows installation USB is the next step.

Does this error mean my Windows is corrupted permanently?

No. Component manifest corruption sounds serious but is usually repairable. The DISM and sfc tools are specifically designed to handle this type of damage. Even in severe cases where those tools cannot fully repair it, an in-place upgrade repair can fix it without reinstalling Windows from scratch. You should not need to wipe your PC and start over for this error.
