By default Windows allows ICMP redirect based route changes.

Refer:

In registry 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters' for 'EnableICMPRedirect' Value is 1 for enabled, 0 for disabled

However default Windows firewall might drop incoming icmpv4 redirect packets.

Refer:

Check for "Networking - Redirect (ICMPv4-In)" in "Inbound Rules" of Windows Firewall using "Windows Firewall with Advanced Security".
