Hi, On your windows machine can you check what DNS server you are using. It looks like your Pi Hole is on 192.168.0.2 but the chances are your router is still providing the DNS server of itself (most likely 192.168.0.1) to devices when they connect.
You can check by opening cmd and typing:
ipconfig /all | findstr DNS
Mine for example shows 10.0.0.6:
C:\Users>ipconfig /all | findstr DNS
DNS Suffix Search List. . . . . . : lan
Connection-specific DNS Suffix . : lan
DNS Servers . . . . . . . . . . . : 10.0.0.6
Connection-specific DNS Suffix . :
If you still see 192.168.0.1 then you need to change the settings of your router to provide your Pi Hole ip of 192.168.0.2 as your DNS server, this will vary depending on the router. You are also able to use Pi Hole as your DHCP server if your router does not allow changing DNS server.
