Linux

I have to use Windows on my work computer and I am finding it hard to get FOSS applications on Windows that can do stuff like

1. Record a video (like SimpleVideoRecorder does)
2. Take a screenshot (there's snip, but it isn't very customizable)
3. Unzip .zip files

Just the routine things I used to take for granted on Linux, so I was wondering if there was a FOSS app store for Windows

And it would be very helpful if someone could suggest alternative for

1. SimpleVideoRecorder
2. Archive Manager

Even the apps I installed for these things either had ads or asked me for payment to record more than 2 minutes of video, I am pretty sure there are FOSS apps to do these things out there, but I don't know where :')

PS: To everyone who has tried to help, thank you very much. I was feeling guilty for not replying to most of you, so I thought I would reply to all of ya, but funnily enough, lemmy had had enough of my gratitude!
