Disabling Scandisk
When Windows is not shut down correctly, it will perform an AutoCheck
using CHKDSK on the next restart.

AutoCheck is executed after a short time delay. AutoCheck can be
disabled or delayed by tweaking a few Registry settings.
Run ‘Regedit’ from ‘Start Menu|Run...’
Go to ‘HKEY_LOCAL_MACHINE|SYSTEM|CurrentControlSet|Control|Session Manager’.
Create a new DWORD value, or modify the existing value, called “AutoChkTimeOut” and set it according to the value data below.
Value Name: AutoChkTimeOut. Data Type: REG_DWORD (DWORD Value).
Value Data: Time in Seconds or 0 to disable (default = 10).
Exit your registry, you may need to restart or log out of Windows for the change to take effect.

Monitoring the system
There are various applications you can use to monitor the state of your system at any given time. One of them is a program called CoolMon (www.coolmon.org) where you can monitor about 22 of the most geekiest system parameters like the temperature and speed of your system fans, the number of processes running, the total available memory on your hard disk and RAM, CPU utilization, etc. Each of these can be individually con. gured to appear on the interface. Best of all, this monitoring happens in real time. Better still, the program is free.
If you need more details than what is offered by Windows System Information or the Device Manager, try out an application called Everest Home Edition (www.lavalys.com). This application hunts through your hardware and software setup and extracts every piece of information you might need about your processor, motherboard, graphics card, hard disk and any other piece of hardware or software information that you might care to know about your computer.

These are only three tricks…..there are many more available on net…..the idea here is not to teach you how to disable right click or how to change the color, fonts, looks, etc…..
The basic reason why I post this chapter is to teach that if registry is the place where all the information is stored then why cant we brake passwords from here???
E.g. I install a software on my system to guard some folders which contain material which I want to hide. In order to access the folder I have to input a password, and if it is right only then I can see the content of the folder. From this example it is clear that the password is stored somewhere in the system from where the software compares the value which I enter in the password field. For this example as well as for every other software which asks for password to access the system features including the windows login password, all these values are stored in windows registry. Whenever the user enters a password, it is compared with the value stored in the system registry, and if it is found correct only then the user is allowed to access the feature.

In Windows registry we can search for specific items, keys, values or software’s using the search function in edit menu. But there is one problem the password is not stored in its original form, it is converted to some other format so that no one can recognize it.
E.g.; If I set the password as “hacking” it is stored as “6167453291” or may be some other form depending upon the software. In such cases what we can do is reset the password i.e. delete the value (whatever it is). Once the value is deleted there is no password and our purpose is solved.
