How To Reset Local User Account Password Windows XP, Vista or 7

All you need is just a USB stick. Can also use CD but its kind of waste because the file size is not more than 10MB. First download the boot file. USB. CD. Floopy(this is super old-school). If using floppy you might need this drivers. PATA/SATA. SCSI.

How to make the CD

Unzipped, there should be an ISO image file (cd??????.iso). This can be burned to CD using whatever burner program you like, most support writing ISO-images. Often double-clikcing on it in explorer will pop up the program offering to write the image to CD. Once written the CD should only contain some files like "initrd.gz", "vmlinuz" and some others. If it contains the image file "cd??????.iso" you didn't burn the image but instead added the file to a CD. I cannot help with this, please consult you CD-software manual or friends.
The CD will boot with most BIOSes, see your manual on how to set it to boot from CD. Some will auto-boot when a CD is in the drive, some others will show a boot-menu when you press ESC or F10/F12 when it probes the disks, some may need to have the boot order adjusted in setup.

How to make an bootable USB drive



  • Copy all the files that is inside the usbXXXXXX.zip or on the CD onto an usb drive, directly on the drive, not inside any directory/folder. 
  • It is OK if there are other files on the USB drive from before, they will not be removed.
  • Install bootloader on the USB drive, from command prompt in windows (start the command line with "run as administrator" if possible)
    • X:syslinux.exe -ma X:
  • Replace X: with the drive letter the USB drive shows up as (DO NOT USE C:)
  • If it seems like nothing happened, it is usually done.
  • However, a file named ldlinux.sys may appear on the USB drive, that is normal.
  • It should now in theory be bootable.
  •  Please know that getting some computers to boot from USB is worse than from CD, you may have to change settings, or some will not simply work at all. If using Windows 7 please run CMD as administrator.

    How to make the floppy

    The unzipped image (bdxxxxxx.bin) is a block-to-block representation of the actual floppy, and the file cannot simply be copied to the floppy. Special tools must be used to write it block by block.
    • Unzip the bd zip file to a folder of your choice.
    • There should be 3 files: bdxxxxxx.bin (the floppy image) and rawrite2.exe (the image writing program), and install.bat which uses rawrite2 to write the .bin file to floppy.
    • Insert a floppy in drive A: NOTE: It will lose all previous data!
    • Run (doubleclick) install.bat and follow the on-screen instructions.
    • Thanks to Christopher Geoghegan for the install.bat file (some of it ripped from memtest86 however)
    Or from unix:
    dd if=bd??????.bin of=/dev/fd0 bs=18k

    After that boot from you respective device and follow simple instruction.

    Facebook surpasses Google

    By Mary Childs

    March 17 (Bloomberg) -- Facebook Inc., the world’s largest social-networking site, surpassed Google Inc.’s search engine in weekly hits to become the most visited Web site in the U.S. for the first time, according to research firm Hitwise.

    Facebook.com accounted for 7.07 percent of visits in the week ended March 13, topping Google.com’s 7.03 percent, New York-based Hitwise said in a March 15 blog post. Facebook almost tripled its visits from a year earlier, compared with 9 percent growth at Google, the most popular search engine.



    Facebook, started in 2004, has lured users by adding games and making it easier to check messages, notifications and friend requests. To compete, Google added a social-networking feature called Buzz to its Gmail e-mail service last month, allowing users to share photos, comments and clips from its YouTube video site. The company is considering building a version that works outside of Gmail.

    Google, based in Mountain View, California, climbed $5.39 to $570.59 at 11:43 a.m. New York time on the Nasdaq Stock market. Before today, the shares had dropped 8.8 percent this year. Closely held Facebook is based in Palo Alto, California.

    Google and Facebook representatives didn’t immediately respond to e-mailed requests for comment.

    Campus Network Problem

    Last week was the slowest internet connection i have ever had at my work place. Seems there was some intermitance in the network.



    After days of thinking how to solve the problem. Finally the issue was a hub connected to a switch & the hub got a looping connection..WTF..such a tiny winny problem causing such a havoc around the campus. All users kept asking why internet are so damn slow...bla..bla..bla..

    Basics steps that you need to do is :

    • block IPs that are caught have a virus or worm.

    • check all network port and make sure that there are no looping.


    Thats all from a beginner=)

    Malware writers abuse celebrity name!!..

    brad-pitt-and-angelina-jolie.jpg Brad Pitt, Beyonce and Justin Timberlake top list of celebrities which their names are being abuse by malware writers. McAfee have issue a list of celebrities this week that are being abuse by those peddling crimeware. As far as the celebrity names that have been most abused and exploited this year to create dangerous Web sites, malware downloads and spam, the top three names, according to McAfee, are:

    beyonce_justin.jpg1. Brad Pitt. When “Brad Pitt screensavers” was searched, more than half of the reporting Web sites were identified as containing malicious downloads with spyware, adware and potential viruses, according to McAfee.

    2. Beyonce. Inputting “Beyonce ringtones” into a search engine yields risky Web sites that promote misleading offers to gather consumers’ personal information, according to McAfee.

    3. Justin Timberlake. Spammer and hackers exploit interest in his high-profile relationships, and a search for “Justin Timberlake downloads” was flagged as leading to spam, spyware and adware.
