NMap command to remember
NMAP -sP 192.168.1.0/24 = to ping all systems in that range
NMAP -sT -p 80,443 192.168.1.0/24 = search all IPs for defined open ports
sudo NMAP -sS -p 80,443 192.168.1.0/24 = stealth search all IPs for defined open ports
sudo NMAP -sS 192.168.1.90 = stealth search for all open ports, best to do this one machine at a time
sudo NMAP -O 192.168.1.90 = OS detection
sudo NMAP -A 192.168.1.90 = OS detection
hide yourself, -D sets the decoy IP address
sudo NMAP -sS -D 192.168.5.5 192.168.1.22
check vulnerabilities in systems
sudo NMAP --script vuln 192.168.1.90
if you type in a command and it needs Sudo, just type in sudo !! (bang, bang), it will run the command you just type without sudo with sudo.... speed
CTRL + K will removes all text at the curser

Windows 10 by default prioritizes it's self for your band width, if you have a gaming PC or a laptop you probably do not want Windows 10 deciding when to us your bandwidth, specially if you are on a limited band width connection (Not everyone has high speed) and of course Windows will start using bandwidth when you need it most, like in a zoom call or downloading something for work.
Lets fix that
This is for Windows 10 Pro so we can use gpedit.msc to change it.
For Windows 10 Home version, you will have to edit the registry (if you are not comfortable editing your registry do not apply this fix)
You may or may not see any improvement but you know that Microsoft isn't using your bandwidth when you don't want them too.
