It seems like there might have been some confusion or a different context meant by "blizzard effect." If you were referring to an issue with a visual blizzard effect on your screen or a related technical problem, please provide more details so I can assist you better. Alternatively, if it was meant as a complement on the thoroughness of the information or another context, feel free to clarify!
If you have any other questions about updating Windows or any other issues, let me know!
