Is there an easy way for a novice to tell the difference between the faulty update and the good one? Is there a difference in file size? Is there a way to compute a checksum in Windows without installing extra software?

I downloaded the mk6 update and the filesize is 84,648,827 bytes, but I have no way to tell whether that is the faulty one or the good one. md5sum: b0208d75e861176f504df0a1ce2ddbf2 kobo-update-4.4.9344.zip

(Edit: I sideloaded the mk4 update to my Glo with no problems, it had a filesize of 100,580,921 bytes, md5sum: 5a1017aca59b6d11ec2ab5134a900898 kobo-update-4.4.9344.zip)
