Hi Anthony,
thanks for this 'golden' tip. After updating I had the symptoms, as mentioned in the MS-letter. (no access in folders, IE didn't work etc.) My puter freezes each time. I struggled sometime arround (forgive me my very negative thoughts in this holy days )and finally I give it up and closed my computer . Worked on my other puter. Luckily I read your post. I just followed the resolution as described, and all worked well again. I was afraid to reïnstall Windows again, now I only had to enter a lot of figures/digits, brrrr.
Thanks,
Cees
