Windows XP activation

Hello Microsoft Product Activation Support,

I am trying to activate Windows XP Professional for an Embedded System

The portal welcome page loads correctly, and I can successfully complete the CAPTCHA.

However, immediately after completing the CAPTCHA, the following endpoint:

https://visualsupport.microsoft.com/captchaa

returns:

"The request is blocked."

The error reference is:

20261104T200646Z-17df698fd5dhfwx9hC1SOF0fxg00000007p0000000009r09

I have reproduced the issue using:

Home Wi-Fi

Office Wi-Fi

Mobile data (4G/5G)

Multiple network connections

The error occurs before the Microsoft account sign-in page appears.

I have a valid Windows XP Professional for Embedded Systems Certificate of Authenticity and product key, and I already have the Installation ID. This is a medical device that runs under winxp

Please investigate the Product Activation Portal CAPTCHA validation/security filtering issue and provide an alternative method of obtaining the Confirmation ID.

Thank you.
