Hi. I'm David, and I'm happy to help you.
Please clarify the following:
- What error are you getting?
- Are you trying to upgrade to Windows 11 using Windows Update, the Installation Assistant, or the Windows 11 ISO?
Also. What is the version and "OS Build" of your Windows 10?
- Press "Windows + R", type
winver, and click OK.
If you prefer, share a screenshot. Use the shortcut "Windows + Shift + S" to use the screenshot tool.
Be sure to censor your email address if it appears. The Microsoft Q&A is public.
I await your reply.
