Hi

I'm Rehan, a Microsoft Windows independent advisor and a windows user like you.

I will happy to help you with your query today.

Error code 0x80070003 is a Windows Update error code that usually occurs when Windows is unable to locate or access the required files during an update. However, in your case, it appears to be related to Windows Mail. Here are some steps you can take to fix the issue:

Restart your computer: Sometimes, a simple restart can fix the problem.

Check your internet connection: Make sure your internet connection is stable and working correctly.

Check if there is any update available for Windows: Go to Settings > Update & Security > Windows Update, and check for any pending updates.

Run the Windows Update Troubleshooter: Go to Settings > Update & Security > Troubleshoot > Windows Update > Run the troubleshooter.

What processor do you have.

You can use GitHub - rcmaehl/WhyNotWin11: Detection Script to help identify why your PC is not Windows 11 Release Ready. Now Supporting Update Checks! to check if there is any problem. The download and a sample screenshot are part way down the webpage.

Hello. Thank you for your reply. As I mentioned, I have applied much more sophisticated methods to solve the problem. I hope that this is an AI response. I have restarted my PC many times. I synchronised time and date. I used Windows troubleshooting and each time it finds some undisclosed error and says it fixed it. I am a Windows user since early 2000-th and for the first time in my life I hear a Windows Mail definition and I have never used such service in my life. Thank you for your answer, but it has no relations to my initial problem

Thank you for your response. Generally, you had a good assumption to what may have been the problem. I've got AMD Ryzen 5800x3D, 16GB DDR4 RAM, X570 motherboard and AMD 7800XT graphics card. Still, I ran the compatibility test you mentioned, just for the sake of argument. It passed. Because I use Windows 11 for 2 years. And installed with no errors two years ago upon release. TPM 2.0 is active. But thank you for your response

Assuming the flash drive you used is the latest available have you tried the update while offline.

The alternative will be to download the latest ISO image from Download Windows 11 (microsoft.com) again go offline and open File Explorer. Mount the ISO and select the new drive that appears then run setup.

Thank you for your fast reply. Tried it offline. Tried older versions of MSDN. Tried changing the flash drive. Tried using Wnidows Creation Tool and tried Rufus. Still, I get the "We are not sure your system is compatible with Windows 11" under Windows 11

Have you ran the windows update troubleshooter.

In windows 11 there is an option to Fix windows with a reinstall. Settings > System > Recovery > Fix problems using windows update > Reinstall now.

There are options in this page WINDOWS UPDATE FAILED - error 0x80070003 - Microsoft Q&A

Do you use a 3rd party AV or Defender?

Look in Disk Management, are all windows partitions on the boot drive? Post a screenshot here in your reply.

Alright, I understand and respect your response.

Did you enable secure boot in bios?

I know you would already have but I thought that I may ask.

Yes, everything is enabled. The installation media just refuses to launch
