Would that include Defender updates? I don't believe they can be removed,
nor have they removed any of my restore points. Since it hasn't happened to
me (and I've used SR since Windows ME), I'd have to see some verified proof
of it happening.
I did a quick search on Google and Microsoft Support and didn't come up with
this reason for losing a point. The closest thing I saw to it was if a large
number of updates were installed at one time or a suite product like Office
was installed, older points were removed because the restore point created
by these scenarios would be so large that older ones were removed to make
room for the new ones. I would imagine that a system that had it's allocated
SR memory reduced to, say, 4 or 5GB, recent points would be removed because
of the size of the new one and the allocation size restraints on the system.
