What is a cumulative update preview

Anonymous

I am a home user of Windows 10. Can someone tell me what is a cumulative update preview? And why is it being offered to me on Windows Update. I normally install all Windows updates that I am offered, but this one (KB4586853) seems suspicious. Why is it called a "preview"? If it is in fact not a real update, then why would I want to install it?

    Previews are (non-security) bug fixes release on the 3rd/4th week of every month (so-called C/D releases). If you don't install it, those bug fixes will be lumped together in next month's patch Tuesday security fixes.

    Hi loyall

    Sorry, I was offline . . .

    Microsoft started releasing those preview updates a while back, they are usually released towards the end of the month, they are basically beta versions of the regular cumulative updates, it is best to wait for the regular patch Tuesday updates, which will contain the code in those preview updates, but possibly a more stable version, because many users do have difficulties after manually installing a preview update . . .

    Thanks DaveM121 and JosephT71 for your assistance. It seem to me that the use of the word "preview" by Microsoft is misleading. As I now understand, these are full fixes issued on a preliminary basis before the fully tested version is made available. In my opinon they had much better be called beta fixes, rather than previews. As a home user I would always stay away from anything beta.

    Exactly. It's not a "preview". It's a way of getting people to act as beta-testers, to see if these updates cause other problems. I wish Microsoft would stop using stupid words to try to fool people.

    You all have missed the essential point! These update previews install automatically without any warning to the Windows 10 user. Previews are said to be optional, but in fact, they are mandatory. Not one person has suggested any way to stop them from installing.
