You can listen to any PDF instead of reading; yes it is possible with Adobe Acrobat Reader 6.0 or above. By using the following Shortcut,

Press Ctrl+Shift+B to hear the complete document (View-> Read out Loud -> Read to the End of Document).
Press Ctrl+Shift+V to hear the page (View -> Read out Loud ->Read This Page).
Press Ctrl+Shift+E to Stop the Speech (View -> Read out Loud -> Stop).

It is not convenient to hear, because the voice is very fast, so U can adjust that by changing the Voice Speed -> Slow Adjustment in the Control Panel -> Speech.

Another Bug in Windows !!!!!

Will Windows work continuously for more than 49.7 days?

Here is a bit of information, which may surprise you all. Windows crashes automatically if you don't switch off the machine for 49.7 Days. Microsoft accepts this.

Do you know why?

In Windows the Virtual Machine Manager (VMM) is responsible for creation, execution, monitoring and termination of virtual machines. This VMM, which is a 32 bit, protected mode operating system entity, provides a number of system services at chip level. One of these services is "Get_System_Time". This particular service loads the EAX register with the time in milliseconds since Windows started on that machine. This service is accurate to 1 ms. EAX is a 32 bit register in Intel 386 Processor onwards.

So the maximum number of milliseconds it can hold is (2³²)-1 = 4294967295 milliseconds = 4294967.295 seconds = 71582.79 minutes = 1193 hours = 49.7 days.

So after 49.7 days the EAX resets to zero. Most of the Drivers use this Time Service to keep track of the Timeout of various services they provide. So after 49.7 days the drivers cannot use the Get_System_Time function of VMM and they crash taking the OS along with.

DISKPART Utility

2006-05-18T11:10:00.002-07:00

Windows XP provides a utility by which u can hide your one or more drives.

Using DISKPART Utility, We can do many things, but now explain how to hide the drives but the data in the drive will be remaining same.

Steps:
1. Go to Start > Run > type “DISKPART "(Without Quotes).
DOS Window will appear with following description.DISKPART>

2. Then type "list volume", that will look like this

Volume ### Ltr Label Fs Type Size Status Info
---------------------------------------------------------------------------------
Volume 0 G DVD-ROM 0 B
Volume 1 C FAT32 Partition 5005MB Healthy System
Volume 2 D FAT32 Partition 10000MB Healthy
Volume 3 E FAT32 Partition 10000MB Healthy
Volume 4 F FAT32 Partition 14900MB Healthy

3. If U want to hide drive D then type "select volume 2"Then a message will appear in same window [Volume 2 is the selected volume]

4. Now type "remove letter D"

Now a message will display that [DISKPART Removed the Drive letter]sometime it requires the reboot the computer.

5. Now open the “My Computer” and check that the Drive D is removed from the list of drives displayed in that window.

DISKPART will remove the letter .Windows XP is not having that capability to identify the unknown volume.Don’t afraid your Data will remain same.

DISKPART will remove the Drive letter only not the Data, so the data will remain same.

To display the Drive Letter Repeat the same process.

But in the 4th step instead of typing “remove” type “assign”,
It means type “assign letter D".

Windows Vista Too Protective....

2006-05-16T11:50:00.000-07:00

One of the most exciting new features in Windows Vista is a major change in the way user accounts work. Windows XP allows accounts to reside in either the Administrators group (they have full control over the system, including the ability to install anything) or in the Users group (they have only the limited privileges).

Windows Vista adds a feature called User Account Control (UAC), which until recently was called User Access Protection (UAP).

When you want to do something that requires an administrator’s privileges, you need an administrator’s permission. For a regular user, that means typing the username/password of the Administrators account or if you’re already an administrator, you just have to click a Permit button. This option allows you to see when a program or process is trying to do something and that will affect your system’s stability, and it’s an effective way to block untrained users from the system.

UAC in the current build of Windows Vista is working, but not well. Some programs fail when they can’t get full system access or when they try to save a file to an area where the current user doesn’t have write privileges. User mode applications should only write data files to non-system locations, such as the user profile.

Windows Vista automatically prompts you for administrator credentials when an application requests them.

Windows Vista adding some extra features to the User account that they can do without the administrator permissions.They are,

Change Power Management Systems.
Change Display settings.
Install Fonts.
Add printers and other devices that have the required drivers installed on computer.
Create and configure a Virtual Private Network Connection.
Download and install updates using User Account Control compatible installer.

In previous versions of Windows, a non-administrator (User) could not easily tell what actions they were allowed to do and what actions they are not allowed. Windows Vista will reduce this problem by using a shield icon throughout the operating system to identify commands that are requiring the administrator privileges.

The shield icon notifies users that they cannot perform the Change Date and Time operation.
