Q1: Is KB917021 included in Windows XP Service Pack 3?
No. SP3 (released 2008) includes updates up to early 2008, but KB917021 v3 must be installed separately even after SP3 – though SP3 has a newer shell32.dll (6.0.2900.5512) that incorporates the fix.

No. The file names explicitly says x86. For XP x64 (which is actually Windows Server 2003 x64 kernel), use WindowsServer2003.WindowsXP-KB917021-v3-x64-ENU.exe.

The original Windows Update service for XP was shut down in July 2020 (WSUS still works locally). You must manually install. Prerequisites:

Q4: Is there a known conflict with Windows Genuine Advantage (WGA)?
No – the update predates WGA Notifications. However, pirated XP copies may fail installation due to catalog signing checks.

The filename includes v3, indicating this was the third version of the patch released by Microsoft. This was somewhat unusual and highlights a significant struggle Microsoft faced during the XP era regarding third-party drivers.
