I can give a few suggestions.
Sublime Text is a very good alternative to Notepad++.
Notes:
- It's technically a free trial but it works indefinitely and completely, regardless.
Airytec Switch Off allows you to schedule tasks for your computer.
PWGen can generate random pool passwords.
TopmostToggle is an incredibly handy tool that lets you set the 'stay on top' state of windows in Windows on the fly.
QTTabBar adds a bunch of stuff to Windows' file browser, most notably: Tabs.
Note: I take no responsibility for any damage QTTabBar might do to Windows, it's a potentially dangerous program if it goes wrong and as such I can't recommend it to anybody who doesn't know what they're doing.
