AWStats is a free powerful and featureful tool that generates advanced web, streaming, ftp or mail server statistics, graphically. This log analyzer works as a CGI or from command line and shows you all possible information your log contains, in few graphical web pages. It uses a partial information file to be able to process large log files, often and quickly. It can analyze log files from all major server tools like Apache log files (NCSA combined/XLF/ELF log format or common/CLF log format), WebStar, IIS (W3C log format) and a lot of other web, proxy, wap, streaming servers, mail servers and some ftp servers.
Take a look at this comparison table for an idea on features and differences between most famous statistics tools (AWStats, Analog, Webalizer,...).
AWStats is a free software distributed under the GNU General Public License. You can have a look at this license chart to know what you can/can't do.
As AWStats works from the command line but also as a CGI, it can work with all web hosting providers which allow Perl, CGI and log access.

What is FreeOTFE? FreeOTFE is a free, open source, "on-the-fly" transparent disk encryption program for PCs and PDAs
With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.
Features include:

• Highly portable - Not only does FreeOTFE offer "portable mode", eliminating the need for it to be installed before use, it also offers FreeOTFE Explorer - a system which allows FreeOTFE volumes to be accessed not only without installing any software, but also on PCs where no administrator rights are available. This makes it ideal for use (for example) with USB flash drives, and when visiting Internet Cafés (AKA Cybercafés), where PCs are available for use, but only as a "standard" user.
• Source code freely available
• Easy to use; full wizard included for creating new volumes
• Both PC and PDA versions are available; data encrypted on your PC can be read/written on your PDA, and vice versa. Supports all versions of MS Windows from Windows 2000 onwards (including Windows 7), and Windows Mobile 2003 and later (including Windows Mobile v6.5)
• No need to install it; making it ideal for use on USB memory drives, etc
• Support for encrypted Linux volumes (Cryptoloop "losetup", dm-crypt and LUKS)
• Available in English, Spanish, German, Italian, French, Czech, Japanese, Croatian, Greek and Russian - with support for other language translations
• Optional support for smartcards and security tokens
• It's powerful: Supporting numerous hash (including SHA-512, RIPEMD-320, Tiger) and encryption algorithms (including AES, Twofish and Serpent) in several modes (CBC, LRW and XTS) - providing a much greater level of flexibility than a number of other (including commercial!) OTFE systems
• Encrypted volumes may either be file, partition, or even disk based
• Much more!

Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your website's FTP password, online passwords (like website member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, website, etc. Unimaginable.
KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key file. So you only have to remember one single master password or select the key file to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish). For more information, see the features page.
Is it really free?
Yes, KeePass is really free, and more than that: it is open source (OSI certified). You can have a look at its full source and check whether the encryption algorithms are implemented correctly.

Complete Memory Dump: A complete memory dump records all the contents of system memory when your computer stops unexpectedly. A complete memory dump may contain data from processes that were running when the memory dump was collected.
* must have a paging file on the boot volume
*  previous file is over written if a second problem occurs
Kernal Memory Dump:A kernel memory dump records only the kernel memory. This speeds up the process of recording information in a log when your computer stops unexpectedly. You must have a pagefile large enough to accommodate your kernel memory. For 32-bit systems, kernel memory is usually between150MB and 2GB. Additionally, on Windows 2003 and Windows XP, the page file must be on the boot volume. Otherwise, a memory dump cannot be created.
It includes only memory that is allocated to the kernel and hardware abstraction layer (HAL) in Windows 2000 and later, and memory allocated to Kernel-mode drivers and other Kernel-mode programs, not include unallocated memory or any memory that is allocated to user-mode programs
* previous file is over written if setting is checked
Small Memory Dump
A small memory dump records the smallest set of useful information that may help identify why your computer stopped unexpectedly.A history of these files is stored in a folder
    The Stop message and its parameters and other data
    A list of loaded drivers
    The processor context (PRCB) for the processor that stopped
    The process information and kernel context (EPROCESS) for the process that stopped
    The process information and kernel context (ETHREAD) for the thread that stopped
    The Kernel-mode call stack for the thread that stopped
* If a second problem occurs and a second small memory dump file is created, the previous file is preserved. Each additional file is given a distinct name. The date is encoded in the file name. For example, Mini022900-01.dmp
To configure startup and recovery options (including the dump type), follow these steps:
    Click Start, and then click Control Panel.
    Click Performance and Maintenance, and then click System.
    On the Advanced tab, click Settings under Startup and Recovery.
Tools for the dump types :
I386kd.exe. - complete & kernla dumps with the windows 2000 support
Dumpchk.exe  - Small memory Dumps

Over the life of an operating system install, configuration changes can occur that prevent the operating system or applications from functioning correctly.
When a formerly working installation suddenly fails, a natural troubleshooting step is to return to the last working configuration that existed when the operating system, service or application last worked, or in an extreme case, return the operating system to its out-of-the-box configuration.
This article describes supported and unsupported methods to undo or rollback changes to the following elements:
· Permissions in the Registry, File System and Services.
· User rights assignments
· Security policy
· Group membership
For windows vista : secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
For windows 2000/2003 server : secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
