How do I fix an error of "couldn't update the system reserved partition" for a Windows 11, Version 24H2 update?

Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

I understand the issue you have. There is nothing to worry, I am here to assist. This issue occurs when the system reserve partition doesn't have enough space. The process might be a little complicated. If you can have someone who can help doing the steps below, that would be the best option, as it needs to delete the font file inside the reserve partition. To do this, kindly follow the steps below:

Step 1. You need to determine if you are using a GPT partition or an MBR:

Press the Windows key + X, then select Terminal (Admin) or Search for Command Prompt and run it as administrator.

Copy, paste, and enter each command below:

diskpart
list disk

If you see a ***** under the GPT column, it is a GPT

If there’s no *****, it is MBR.

Example of GPT:

Once you identify the partition, kindly follow the steps from the link below under "Second, choose which method you need:"
