There are several ways to effectively speed up your computer. If your computer becomes slow, read this article.
Steps

Step 1. Use the command line
From the command line, you can control your computer: send tweets or instant messages, play mp3 files (via mplayer), browse the web (via Lynx or Links2), torrent (rtorrent), edit images (ImageMagick), read news (raggle), use chat (irssi), manage downloads (axel, wget), etc. It is very easy to use the command line on Linux and BSD, but it is not so on Mac OS X and Windows.
Action | Windows / DOS | Windows Powershell, Mac OS X, Linux, BSD etc. |
list files / folders | dir | ls |
clear console | cls | clear |
copy files | copy | cp |
move files | move | mv |
delete files | del | rm |
create a folder | md | mkdir |
delete folder | rd | rm -rf |
change current folder | cd | cd |
current folder | cd, chdir | pwd |
Search | find | grep |
change access rights | chmod | chmod |
display text | echo | echo |
add user | net user | adduser |
If you prefer using a graphical interface, proceed to the next step. But the benefits of using the command line are undeniable.
- If you need to move all folders ending in "photo", it is very easy to do it on the command line, but very difficult to do it through the graphical interface.
- Command line completion also speeds up computer management.
- In Linux it is possible to abbreviate commands and their sequences.

Step 13. Go to the "Startup" tab and uncheck the boxes for all programs or processes that should not (in your opinion) be loaded along with the system boot
Attention! Disabling the process used by Windows may lead to system instability! Before shutting down a process or program, make sure you know the exact purpose of the process or program.

Step 14. Before the next step, display hidden files and folders
To do this, click "Start" - "Control Panel" - "Folder Options". Go to the "View" tab and check "Show hidden files, folders and drives."
