Only in MBR mode. On computers less than 10 years old, you can go into the UEFI settings and put Grub above the Windows bootloader in the boot order list.
Some broken computers only boot the “flash got wiped, let’s hope this one works” fallback bootloader. Windows and Grub will fight for that one, but that should only happen if your motherboard’s UEFI settings got reset or if the firmware is buggy.
