I use DBeaver for all of my database interaction, and then some. Parsing a csv file with sql is very satisfying.
Greenshot since snipping tool kinda sucks.
Powershell, with domain wide remoting configured. I can “ssh” into any machine instead of screwing around with remote desktop. Also scheduled scripts can make maintenance a breeze. Throw chocolatey on top of that, then there will be very little that can’t be done remotely (gpo software deployment rarely works, even when it does)
Ubuntu subsystem for ssh and off-label uses of telnet (putty is only good for direct serial console connections imo)
