Recover / Reset Windows XP Administrator Password

Somtimes we forget our windows password. We don't have any way other than to install everything fresh, or do we have a few methods to recover or reset. Yes we do, follow the three process explained below ...

Process 1:
Whenever we install Windows, it automatically creates an account “Administrator” by default and sets its password to blank. So Start your system and press ctrl+alt+del keys together twice when you see Windows Welcome screen or Login screen, and it’ll show Classic Login box. Once the Logon box is displayed type Administrator in Username and leaving the Password field blank press Enter. You should be able to log in to Windows.
Now reset your account password from Start -> Control Panel -> User Accounts.

Process 2 :
Windows XP and next versions also allow another process to recover/reset forgotten password by using “Reset Disk“. always create a Password Reset Disk while installing windows or later in a convenient time. You can use that disk to reset the password. Please visit following links to know more ...

If the two process mentioned above doesnot work the try the next process. It is a bit lengthy process but wothwhile if you can recover/reset your password without a complete fresh install.

Process 3:
If the above mentioned tricks doesnt work, then try following trick which is actually a loophole in Windows XP Setup and a big security hole:
1. Boot using Windows XP Setup CD and continue.
2. Accept and press “R” to run the repair when it asks to repair your existing Windows installation,
3. Setup will start repairing your Windows and will start copying files, etc. After a few minutes setup will restart your system.
4. Now it will start doing other tasks and will show a small progressbar with a few details in left side.
5. When it shows “Installing devices“, press Shift+F10 keys together in your keyboard.
6. It will open a Command Prompt window. Now type nusrmgr.cpl and press Enter.
7. It will open the same “User Accounts” window which you see in Control Panel. You can reset your password now.

Seagate releases 1.5 TB Hard Disk Drive

The 7200.4, as the name suggests, targets the high-performance end of the magnetic drive market, and ships with 16MB of cache. As for the 7200.11, it'll slot in at the top of that product family. The main difference between the new 1.5TB drive and the 1TB ST31000340AS already available is their platter density. Both disks are four-platter designs, but the 1TB drive uses four 250GB platters, while the new 1.5TB is apparently using four 375GB platters. 375GB seems a bit odd for a platter size, Samsung's new 1TB Speedpoint F1 drives now use three 333GB platters instead of the original 4x250GB configuration the drive first shipped with. The Seagate Barracude 7200.11 will spin at 7,200RPM, and connects via the SATA I interface to achieve 3Gb/s transfer rate as well as a sustained data rate of up to 120MB/s.which is why Seagate has other choices for the budget conscious in the form of 1TB, 750GB, 640GB, 500GB, 320GB, and 160GB varieties, accompanied by cache options of 32MB and 16MB.

Well, the Barracuda hard drive will target desktop users, so where does that leave us notebook totters? Thankfully Seagate engineers also have this group in mind, introducing a couple of 2.5 500GB hard drives under the Momentus line. These will be available in 5,400RPM and 7,200RPM variations, accompanied by 8MB of cache and 16MB of cache respectively. Both drives will feature free-fall sensor technology to prevent data damage when dropped by parking the heads off the disk whenever it detects any changes in acceleration equal to the force of gravity, all within 3/10ths of a second.

Increase Battery Life of Your Laptop PC !!

Photobucket

Before we buy a laptop / notebook, we must take into account the following factors which determine maximising the battery life of a laptop / notebook.

1. Screen size of the PC. Bigger the screen size less you get as backup from battery. Small size screens such as 13" or 12" give you better back as compared to 15" or 17" screens.
2. A 9 cell battery will provide you with more backup time than a standard 6 cell battery.
3. Opt for Splid State darh Disk Drives as they comsume less power compared to PATA / SATA Hard drives which has moving parts so consumes more power.

Gudelines for Obtaining Optimal Battery Backup
  • Always use up to date device drivers as they will run your PC more smoothly using all the hardwares to their optimal performance. Older drivers may consume more power compared to new device drivers.
  • The Operating System you choose is also an important factor while obtaining optimal performance from your PC. There will be clear notification ( you will see sticker / label written as designed for Windows XP / Vista etc) for a particular operating system on your laptop / notebook. That means that particular OS will give you optimal performance and better battery backup. Other OS may not have proper driver support to maximise the system performance resulting poor backup. So, use only certified OS for your PC. Remember to update your OS from time to time from their website.

  • Use Certified hardware by manufacturer while upgrading the PC like RAM, HDD etc. Uncertified hardware will definitely consume more power.
  • You may also tweak Windows Power Management properly according to your needs to get maximum battery life.
