I tried running these commands in PowerShell, but bcdedit commands would not work even as Admin.

bcdedit /copy {current} /d "No Hyper-V" 
# The entry was successfully copied to {01afc27f-do-not-use-5e2f3b11ce9a}. 

bcdedit /set {01afc27f-do-not-use-5e2f3b11ce9a} hypervisorlaunchtype off 
# The operation completed successfully.

The default prefix binding is CTRL-B

Sessions

tmux new -s my_session
tmux detach (prefix + d)
tmux list-sessions
tmux attach -t my_session

To kill a session, use prefix + :kill-session.

Notes on ag.vim

This plugin is a front for ag, A.K.A. the_silver_searcher, https://github.com/rking/ag.vim

Usage: ag [FILE-TYPE] [OPTIONS] PATTERN [PATH]

Ag searches from your current working directory if a PATH is not given.

Check your working directory in Vim with :pwd
Change your working directory with :cd [PATH]

Basically (and very roughly), the standard paths on Unix are:

/bin & /sbin for vital programs for the OS, sbin being for administrators only ;
/usr/bin & /usr/sbin for not vital programs, sbin being for administrators only ;
/var for living data for programs. It can be cache data, spool data, temporary data (unless it's in /tmp, which is wiped at every reboot), etc. ;
/usr/local for locally installed programs. Typically, it hosts programs that follow the standards but were not packaged for the OS, but rather installed manually by the administrator (using for example ./configure && make && make install) as well as administrator scripts ;
/opt for programs that are not packaged and don't follow the standards. You'd just put all the libraries there together with the program. It's often a quick & dirty solution, but it can also be used for programs that are made by yourself and for which you wish to have a specific pa
