Improving Security PC / Laptop

Or modify the various configuration on Windows. Also can other people see your files confidential. Something like that is very possible when your computer is the computer "general". That is a lot of other people who helped put on, for example, friend, brother or sister. Remember, a beginner (in the case of computers) are usually very happy to try out everything on the computer. Now, to avoid things we do not want that happening on our machine you can try various steps below:
1. BIOS password
The first time you have to put a password on your BIOS. Why? Because in BIOS there are facilities for enable and disable some of our computer resources. While there are easy ways to penetrate this password, but at least it will slow down the intruders ....
2. Make sure the boot only from hard drive.
In your BIOS, make sure the settings for booting from the hard drive only. In other words disable booting from a floppy disk facility, CD-ROM, or other media.
3. Disable Start-up Menu
With the startup menu to disable it so other people (including us) can only boot from Windows (can not boot to DOS Prompt). How, in the config.sys file add: Switches = / F / N to config.sys. At the top of the autoexec.bat file add:
@ CTTY nul
@ BREAK OFF
@ ECHO OFF
Being at the very end of the autoexec.bat file add: CTTY CON
4. Boot Key disable
Its purpose is to prevent the F8 key and pressing F5 during the boot. By pressing F8 will display a start-up menu. Mendisablenya mode: Open the MSDOS.SYS file located in the main directory (C:) with Notepad. Then changes into Bootkeys Bootkeys = 1 = 0.
5. Hide icon in the Control Panel
In Control Panel there are various facilities for setting / configuration on our computer. For example the setting of passwords, printers, desktop themes, etc.. Well if you do not want anyone else who wants to change the settings on your computer, you can perform the following actions, namely hiding the various icon in Control Panel. How, first open the file control.ini contained in the folder c: windowscontrol.ini (if your windows folder called other, please adjusted). Then under the section [do not load] please do not enter the facility you want to show. For example to hide the icon password please write "password.cpl = no". To hide the Desktop Settings icon, then write desk.ini = no ", and so on. To see a list of *. CPL file you can see in c: windowssystem.
6. Software Protection with
Protection software can be many different forms. First encryption. By performing encryption (encoding) another person would find it difficult to open files that are encrypted. At the time we are required to perform encryption to enter a password, which password will also be used to perform decryption. That way people who do not know the password will not be able to open the file and will not know its contents. Examples of software used for encryption is Cryptext, PGP, etc.. In addition to using encryption there are other ways to secure our files is done using the software Win-Secure It and Folder Guard. With our software can hide files / folders, prevent the execution of the program, preventing deletion (delete), etc.. Files that have been hidden (hidden) will not be visible in Windows Explorer even if the Show All Files option is enabled. Preventing others to execute / run the program becomes very important if you have the software to configure on Windows, such as WinBoost, Tweak UI, the Start Menu Changer, and so forth.
7. When you include paranoid
With the six steps above your computer already has a decent level of security which (certainly not good for a hacker). But when you include paranoid or really scared diisengin others your computer you can continue with the next step. Ie delete or rename these files is that including the category of "dangerous" if it is executed, such as fdisk.exe, format.exe, etc.
