7-zip, Ninite (a customized version per computer, although I own a pro licence), Sumatra and, depending on the computer's end user, ZoomIt goes on EVERYTHING.
-I generally go with the Avast
https://www.avast.com/en-ca/index#pc anti-virus engine, even though the nags get a little overly-naggy
-Greenshot
http://getgreenshot.org/ for taking screen caps and then annotating them.
-F.Lux
https://justgetflux.com/ cuz I'm still using Windows 7
-WizMouse
https://antibody-software.com/web/softw ... the-mouse/ which allows me to scroll non-active Windows (usually x2). No idea if it works with Win10, but indispensible
-7 Sticky Notes
http://www.7stickynotes.com/ because I don't like gunk on my monitor
-System Scheduler
https://www.splinterware.com/products/scheduler.html (the free version) for doing scheduler tasks. Dead easy and quick.
-I use the ridiculously cheap Spartan Lite
http://m8software.com/clipboards/sparta ... anlite.htm for Clipboard management, but there's a free version called M8
http://m8software.com/clipboards/freeclip/freeclip.htm from the same guys
-I get by with the free version of Evernote after paying for a few years. I've tried to install One-Note a gazillion times. No go for me. YMMV
-Password Safe
https://pwsafe.org/for giving me a localized copy of the passwords stored in Last Pass (which is indispensible and rather inexpensive)
I echo all the apps from Nirsoft and SysInternals as needed. And I agree that most of the ones from the DesktopOK guy are worth looking at, even that one that Nikos would rather not see mentioned here. When I'm dealing with moving files out of a holding tank to five or six folders, I find having a couple of windows open helps me do it quickly with drag and drop. STILL use x2v2.5, don't get me wrong. But as TARGETS, the extra window helps.
From a notoriously penurious guy!
