Make elevated network drive mappings show up in Explorer

Create a REG_DWORD named EnableLinkedConnections in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System, set it to 1 and restart.

Setting this registry value stops Windows separating network drives by elevated vs unelevated tokens, thus whenever you create a network drive in an elevated PowerShell, it automatically becomes available in unelevated applications such as File Explorer or a PowerShell that isn’t running as admin.
