Stupid mouse keeps doubling my single-clicks

Funny enough, everyone says it's a hardware issue. I don't think so. In fact, recently, my friends and I who all have different mice and one who actually recently got his have started having the issue. Sometimes it just randomly double-clicks, and it's not consistent. There's not a "reproduce like this" sort of thing. I don't hate Windows or anything, I just think it was something in the recent update. On an unrelated note, Steam has also started running really poorly for my friends and I.

Some things to note for the reason why I think it's Windows:

Friend 1 hardware: I5-6500, Razer Deathadder
Friend 2 hardware: Phenom II x6 1055t, Corsair Glaive
My hardware: Ryzen 7 1700, Logitech G602

I left all the other hardware out to not make this an essay lol. But my point here is that these are all different generations in terms of internal hardware (if I can word that properly, I hope you know what I mean, sorry :|) and they all run Windows. The only relatively common point all of them have is that they are gaming mice. Maybe it's a bit of an issue the OS has with gaming mice? The Corsair Glaive is the one that's new btw.

Well, mine was definitely hardware. I replaced my tired MX Master with a new MX Master 2S and the problem went away.

I am having another issue with Win10, in that most of the images I download from the internet have green thumbnails. As in there's no thumbnail, just a green block/rectangle. I tried a system repair, with no dice. Both the picture issue and the mouse problem are still present.

And now I am sometimes unable to scroll through the list of programs on the start menu with my mouse wheel even though my mouse wheel works fine. This really seems more like W10 issues than anything. A new mouse may have fixed it for some because the prior one had some weird driver issue with W10

I've had this problem numerous times on HP laptops and on every occasion it appeared to be registry corruption or at least my profile had become corrupted somehow. I had very little of importance on any of the machines so most times this problem of the mouse double-click reared its ugly head I simply set up a new profile, by setting up a new local account and making sure the problem wasn't an issue while logged into that. I have a few suggestions to try before that though, some you'll be aware of but others reading this when they google the problem might not:

1) Open control panel and choose "folder options". On the first page you land will be the option to set the opening of files/folders to a single click of the mouse or a double click. Just make sure this hasn't accidentally been set to single-click and if possible, revert that setting to opening files requires a double click of the mouse. Almost every time I had this problem the option to revert to requiring a double click was greyed out and I couldn't choose it. This was confirmation there was nothing wrong with my hardware, but something gone wrong in the system. If it's greyed out for you then don't blame your mouse, your settings somewhere are the culprit, be it registry corruption, your mouse settings (which you can also check from control panel), wrong/outdated drivers etc.

2) If practical try using system restore to a date before the one when you first noticed the problem. That may fix it but depending how far back your restore point was you'll lose any app installations, updates performed after that date and you'll have to repeat them. If it doesn't solve the issue you can always undo the system restore to bring you back to where you were. Similarly if you have a system backup image from before you noticed the double-click issue you can restore that, but everything you installed/updated since the date of the backup will be lost so you might be reluctant to try that out.

3) This fixed the issue for me 100% of the time: set up a new profile with admin priviledges (you can change to standard account shortly after if you wish) and move over as many personal files as you want, check that the mouse is working as it should, and if that's enough for you then delete the old, surplus account.

**NOTE**
There are a lot of other troubleshooting steps I tried with a low success rate, such as delving into the registry and finding and correcting any wrong settings that applied to the mouse, installing different drivers, checking for malware and always checking for profile corruption. You must check for profile corruption before setting up any new account because if that is the root of the problem then any new profile will be corrupted just the same unless that's resolved first. There are How-To's on this site regarding profile corruption and how to check for it and repair it. Do that before setting up a new account so you know your new profile is clean and uncorrupted.
If the mouse-click problem no longer exists in the new profile you know there are settings somewhere in the original profile that caused your issues. You might not want to move to the new account for various reasons though, and instead only use it to check that the problem is gone when logged into it. In that event go back to your original account and troubleshoot the issue as best you can but even on the few occasions I was able to do this successfully I found myself spending whole days inside the registry and ultimately it was more trouble than it was worth and since I had nothing of great importance that I'd lose by setting up a new profile this is the solution I found most effective for me. Try nos. 1 and 2 above first though since they're easily done and might work out better for you.

***IMPORTANT***
It's best to set a system restore point, back up your registry and/or perform a full system backup before making any significant changes to your settings so that you at least have the option, if your attempts to fix things only end up making things worse, to return to your system back to its present state, as frustrating as it is.
