Computer issue

For the first ever, in about 27 years of running my own business, I have had a computer crash in such a way that it seems to be preventing important data recovery off the drive.  Some data has been recovered, but a really useful part of what's on there is proving difficult to retrieve.

This problem also seems related to a windows update.  

This is...disappointing.  I have had a great run of not having unexpected crashes.  I did have a virus problem once, but it wasn't the worst kind.  

Oh well.
