I appreciate TechSpot for tips like these, as well as the sensible reviews.
Has PowerToys been mentioned before?
FancyZones is a particularly neat component for custom window-snapping grids, especially on wide or vertical displays (instead of the default 2x2 layout).
Other free general utilities I use:
- StartIsGone (hides Start menu button for more taskbar room. I also make a Toolbar of shortcuts with small icons, instead of pinning everything)
- QTTabBar (adds browser-like tabs to File Explorer)
- Everything (fast file search)
- WizTree (shows what files are taking up space - faster than WinDirStat)
- PushBullet (read/dismiss phone notifications & reply to SMS on desktop)
- WeatherBug (see local temperature in the system tray - imperfect but best I've found)
- IrfanView (fast image viewer)
- VirusTotalUploader (drag & drop file scanner)
More specific-purpose ones but worth mentioning:
- RegScanner (fast registry search)
- HardwareInfo (detailed specs)
- SublimeText (advanced text editor that isn't bloated so it starts up instantly)
Networking:
- Mouse without Borders (use multiple PCs with the same M & KB)
- AnyDesk (remote desktop)
- RadminVPN (simple & unlimited virtual LAN)
Media:
- YouTubeDL (works on various sites, bit harder to find now but still does it's trick)
- LosslessCut (quick and easy way to make clips from videos)
- Mp3DirectCut (like above but for cutting MP3s)
- VidCoder (simple video encoder, alternative to Handbrake's UI)
- MkvToolnix (remove foreign dubs & subs from videos with ease)
EDIT: Let us know if you've found similarly-useful tools or better (easier/faster) alternatives!
