Here is 1 for you:

> As far as I can tell, as long as Windows Defender (and presumably other A/V scanners) are running, there's no way to make the Windows I/O APIs consistently fast.

This is really even a common knowledge - if you did ANY IT work, you should already know it. I can't count the number of times when server wasn't working correctly when it turns out it just has Defender on.

Yes, PC desktops commonly run AV which can impact certain common subsystems in their routine operations. This is true on Windows, Linux, and MacOS. This is perfectly reasonable for the 99% of PC users that are not programmers and power users.

> it just has Defender on

It's unfortunate Defender would come pre-installed even on Server.

You are hilarious.

It's a good post, but it doesn't substantiate your hyperbole.

Yeah, because I am not babysitter. You should do your homework :) I am glad when people hint me good info.

I do have ample personal experience - when government web server was randomly dropping from 2k req/s to 2 req/s we disabled defender and from there we had continuous 2k req/s. I have seen this literary hundreds of times. Not sure why people install AV on servers but its common in banks and similar. On home computers its even worst. I witnessed new laptop computer with 2 AVs - defender + something vendor installed like mcafe. It was so slow that while typing letters appeared 1/s.

AVs inject themselves on number of places and do all kind of "funky" stuff. All power users should disable that junk. You have other means to protect yourself. If you are grandma, sure, go for it, but grandma will not run "Reclaim Windows10" from github gist, no ?

Context is everything. It certainly doesn't justify above comment claiming "DO NOT DO THIS!!!" on HN. Its utter nonsense. We are here to talk about hacking things by definition. Power users customize their OS, not the other way around. Its pity that MS doesn't provide minimal OS (like Linux OS's usually do) but the first thing I do is not run single script like Reclaim, but dozen of such scripts and my healthy nervous system thanks me all the time because benefits are huge and minuses are minor and fixable.

If anything, we need more projects like that, more polished, more documented, more maintained. My personal fav so far is [1]

Nobody uses antiviruses on Linux (except if they host a mail or file server). As far as I know most people who use MacOS do not either. It is true that a lot (most?) windows users use antiviruses but this is not an argument against the claim that it causes massive slowdowns.
