It is a complex configuration, but it is worth it to see a warm download come down that originally took 30 mins instantly to a second client. I didn’t know how much of the updates are the same across different vendor laptops.

There have been several people over the years.
The collected information is being gathered at 
<https://wiki.squid-cache.org/ConfigExamples/Caching/WindowsUpdates>

If you would like to check and update the information for the current 
Windows 11 and Squid 6, etc. that would be useful.

Wiki updates are now made using github PRs against the repository at 
<https://github.com/squid-cache/squid-cache.github.io>.

FWIW, what I have seen from routing perspective is that Roblox likes to 
use custom ports and P2P connections for a lot of things. So no high 
expectations there, but anything cacheable is great news.

There is no significant differences AFAIK. They both come down to what 
you have configured. That said, the ongoing improvements may make v6 
some amount of "better" - even if only trivial.

For Windows I would expect the only "100% sure" way is to completely 
forbid access to the disk where the cache is stored.


The rest of your questions are about container management and Windows 
configuration. Which are kind of off-topic.
