#### Proxy Behavior
For Windows Update (WU) scans URLs that are used for update detection ([MS-WUSP]: SimpleAuth Web Service | Microsoft Docs, [MS-WUSP]: Client Web Service | Microsoft Docs):
- System proxy is attempted (set using the `netsh` command).
- If WUA fails to reach the service due to a certain proxy, service, or authentication error code, then user proxy is attempted (generally it is the logged-in user).
