They acknowledged that the Windows 2000 design was also used in XP (https://www.computerworld.com/article/2539986/microsoft-conf...), but Vista and above used NIST algorithms defaulting to CTR_DRBG, although the problematic Dual_EC_DRBG (which was flagged by their own cryptographers as problematic: https://rump2007.cr.yp.to/15-shumow.pdf) was present until the Snowden revelations.

Windows 10's (and 11 and probably above) implementation of CTR_DBRG is different from Vista-8 though, mainly in the entropy generation and the switch from AES-128 to AES-256.
