Automatic Defraging in Windows Vista

In Windows Vista, Windows Disk Defragmenter has an option to run it at scheduled times. This feature is provided via Control panel.

I read somewhere that this schedule task always runs at low priority of CPU. The underlying disk access algorithm is changed so that it doesn’t put overheads on system and affect its performance.

As in windows XP you need at least 15% of free disk space in order to run Defrag without getting halt at 10% of its completion. In windows Vista there is no such restriction. t seem the bar of 15% free disk space in removed.

I am eagerly waiting for arrival of final and stable version of Windows vista SP1. The reason: Current user interface of Defrag is over simplified and here lies the catch. It doesn’t allow you to select which partition or volume to defrag. In SP1, this problem is going to be fixed and options are going to be provided to select the drive letter.

Here is a Step by Step method to run Defrag Automatically in Vista

1. Click on Start
2. Choose Control Panel
3. Select the Control Panel Home
4. Click on System and Maintenance
5. In the Administrative Tools, click Defragment your hard drive
6. You may need to grant permission to run the disk fragmentr
7. Click on Run automatically (recommended)
8. Click OK

Happy Defragging

Administrator password in windows 2008 Server

I downloaded the ISO of windows 2008 Server and burnt the CD. I tried to install it on my Intel Quad Core CPU based system. The installation was a monotonous job, as I did not encounter any problem or configuration issue.

After successful installation, the system rebooted and it reach to a stage where it asked me to enter a Administrator password for fist time login. Here I selected my old windows 2000 server password as I don’t want to remember any more new password. As I really don’t need that kind of stringent security as Microsoft expect from me, I thought old password would worked for me. Here only Windows 2008 showed its true color. I got the message.
The message indicated: Passwords must meet complexity requirements

I tried various combinations but in vain. None of the password worked for me.
I read the help document on Microsoft website. It says password must have
• English uppercase characters (A through Z)
• English lowercase characters (a through z)
• Numerals (0 through 9)
• Non-alphabetic characters (such as !, $, #, %)

The password must contain one CAPITAL letter, one number and one small letter or non-alphabetic r. So my password, which was earlier alphanumeric as “safe2092”, couldn’t work. I just changed it to “Safe2092” and it starts working.
Bottom line: Just use one CAPITAL letter in your old alphanumeric password that’s all to satisfy the complexity requirement of windows 2008.
