Remove Windows Update endpoints that are no longer required post-2506.

[NeilBird]

Summary

Updates the nine regional Azure Local firewall endpoint lists under HCI/ to remove Windows Update related endpoints that are no longer required for new Azure Local deployments (2504/2506 and later), and aligns the "Arc gateway support" values for the bootstrap-phase endpoints with the official guidance in Overview of Azure Arc gateway for Azure Local.

The HCI/OEMEndpoints/ folder was intentionally left untouched.

Regions updated

Australia East, Canada Central, East US, Central India (India Central), Japan East, South Central US, South East Asia, US Gov Virginia, West Europe.

Changes

1. Removed Windows Update / delivery endpoints (no longer required)

Removed the following rows from each applicable region:

Endpoint	Component	Notes
*.dl.delivery.mp.microsoft.com	AKS Arc VHD	Not required starting with 2504 new deployments
fe3.delivery.mp.microsoft.com	Azure Local Updates	Not required starting with 2506 new deployments
fe3cr.delivery.mp.microsoft.com	Azure Local Updates	Not required starting with 2506 new deployments
tlu.dl.delivery.mp.microsoft.com	Azure Local Updates	Not required starting with 2506 new deployments

Notes:

• msk8s.sb.tlu.dl.delivery.mp.microsoft.com (Arc Resource Bridge OS images) was retained in every file.
• US Gov Virginia had no *.dl.delivery.mp.microsoft.com row, so only the three *.delivery.mp.microsoft.com rows were removed there.

2. Arc gateway support values (bootstrap-phase endpoints)

For the endpoints that are not redirected through the Arc gateway prior to bootstrap, the "Arc gateway support" column was changed from Yes to No:

• aka.ms
• azurestackreleases.download.prss.microsoft.com
• <region>.login.microsoft.com

3. Consistency & correctness fixes

• Renumbered the Id column sequentially (1..N) in every table after the row removals.
• Fixed cross-region copy-paste errors in the Notes column:
  • East US: "...guest configuration services in Australia East" -> "East US".
  • US Gov Virginia: "...logging into East Us Azure" -> "US Gov Virginia Azure".
• Normalized the South Central US table header (Required -> Required for) to match the other regions.
• Normalized the apostrophe style in the Australia East file to match the other eight files.

Validation

• All tables verified structurally valid (consistent column counts, no duplicate endpoint URLs, valid port values).
• Id columns confirmed sequential 1..N in all nine files.
• File encoding preserved (UTF-8 without BOM, CRLF line endings); no cross-region references remain.
