Make you Windows 7 Boot and Shutdown Faster


It's very good news if your laptop and PC have slow booting and shutdown, so simply put, this little collection of tools will help you to gain control on quicker start times, internet confirmation, shut down times as well as throwing in some performance improvements.  As a bit of a start though, lets discuss two of the largest causes of a lengthy boot time on a computer, automatic updating and virus programs.  A great many programs leave files in your startup folder and automatically set themselves to automatic updating on installation.  Automatic updating can increase your boot time by 6-60 seconds, and more, depending on what you have installed.

For example, I use a great optimization utility called Advanced System Care which does a great job keeping my system clean.  It only get used when I choose so I never considered that it would be the cause of a 7-8 second delay in my start time.  It turns out that, in the programs Options menu, there are two check boxes, one for starting the program automatically at start up and the other for automatic updating.  I simply unchecked them and got that time back but who knew right?

The other consideration that I mention has to do with finding the right virus program.  I like freeware myself and have had the opportunity to check the start times of four programs in the past while.  Was I surprised to find that the best program started in the least amount of time was 5-6 seconds while at least two others chocked 10-15 seconds on to the boot time.


A. Configuration File Adjustment

The Configuration File can be found by pressing the WinKey + letter ’R’ simultaneously which will bring up the Run command. From there, type ‘msconfig’ into the box and press enter. While here we are going to perform a few changes to decrease our boot time:
Check  No GUI Boot which will stop the colorful opening ceremonies of the software and save you precious seconds at start up as will these others;
Reduce the Delay time to 3 seconds;
Choose Advanced options and select 2 for the number of processors if you are fortunate to have such; and
Click on OK followed by Apply and then agree to restart your computer.

B. Remove any Unused and Unneeded Services

Windows 7 running services can potentially be the main cause for slow start and performance in a computer system. Many of the services are never used by the computer as the general settings are meant to cover any number of computers and their configurations. On first seeing the Service Applet, the columns will show the name of each service, description, status and start-up type. The user needs to carefully consider the properties of each one to determine if it needs to be running or not. The safest method of approach is to set services to manual, when unsure, rather than to disable them.

So, simply press WinKey + ‘R’ to again bring up the Run Command and type in ‘services.msc’ before pressing OK. Double clicking on any service will help in determining if it is useful or not as well as changing its properties.

Some services that start automatically, by default, that can be disabled are:

• Computer Browser
• Distributed Link Tracking Client
• IKE and AuthIP IP Keying Modules
• Offline Files
• Remote Registry
• Tablet PC Input Service (If you are not using a tablet)
• Windows Error Reporting

You can experiment carefully with some services and I would suggest only a few at a time and then return if something doesn't work as planned or there are adverse results.


C. Eliminate Unneeded Start Up Programs

Start Up programs, as with Windows Services, have the ability to slow your system down a great deal. Start Up programs are a bit more obvious to the typical user however. Many software programs, on installation, embed files within the Start-up folder that are running behind the scenes needlessly. Quick Time is famous for this as is MS Office, however, MSN Messenger and the many communications programs that start automatically are a better example.  My best suggestion is to choose quicker boot times rather than starting frequently used programs automatically.

To examine your Startup, press WinKey + ‘R’ and type ‘msconfig’ and OK. From there select Startup and examine the running files. Again, determining what you can shut down may take a bit of work, however, my policy is that if I can start it when I select the program, there is no need for its files to be running all the time and slowing my system.


D. Remove Unused Fonts

I have just counted and was astounded to learn that there were a total of 708 fonts installed on my computer by Windows 7 taking up a whopping ½ GB of space, all but three of which I may never use. Windows loads each and every one of these fonts at boot up and must keep track of them, thus slowing your system. Feel free to cut down on the total number by simply deleting them. Go to Start Menu/Control Panel/Fonts.


E. Get Quicker Internet Confirmation

There is a quick trick to getting your internet to confirm quicker on boot. Press Winkey + ‘R’, type in ‘services.msc', double click and disable Workstation.

PRECAUTION: This tweak is not advisable if your system is located within a network or workstation environment as it will affect the environment itself.


F. Speed Up Your Shut Down Time

Windows 7 allows you to control your shut down time and allows it to be set from instantaneous to a 20 second delay. In considering this, your work habits need to be thought of and whether or not there is data being saved on exit. My shut down time is set at 2 seconds which I find a perfect setting as I hate waiting for a computer to shut down. We need to go into the Registry for this one so buckle up!
Press Winkey +’R’ and type ‘Regedit’ which brings you to the Registry Editor;
Follow” HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control and then look to the right to find WaitToKillServiceTimeOut and double click on it. You can enter a value from 2 to 20000, each value representing a millisecond. Two seconds would be 2000; and
Again click OK and then simply exit the program; it will be saved automatically.

How to login Multiple User in One Computer in Windows XP


This is really superb solution to use single computer by multiple user, in built RDP (Remote Desktop Protocol) provide to access the computer remotely but it has a limited only single user can be take a remotely at a time.

Typically, if you were logged in with RDP on a computer, if someone else tried to remote into that computer at the same time, you'd be bumped off. There are a couple of cases where you might want or need simultaneous RDP sessions. You and your partner could both access a home computer's programs and files while at work, for example. Or, as TechSpot suggests, you could have a dedicated Media Center PC in the living room and remotely access all the files on the computer without interrupting someone watching TV.

This patch will enable two or more concurrent sessions in Windows XP PRO Service Pack 2 (SP2) and Service Pack 3 (SP3) if you have FAST USER SWITCHING enabled, and your windows is NOT in a domain.

Uninstaller is also included and can be found at windows Control Panel -> Add or Remove Programs.

NTSC and PAL video standards

NTSC and PAL video broadcasting standards

There are currently two types of analog format used to broadcast video signals throughout the world. Certain parts of world use NTSC, which stands for National Television System Committee, while other parts of the world use PAL, which is short for Phase Alternating Line. There are several important differences between PAL and NTSC signals which are good to know about since they affect how certain technologies (such as DVDs) work in different countries. This Bamboo AV Advice article will help you to understand the differences between NTSC and PAL video standards, and will give you a good overview of what will happen to television systems and broadcasting standards in the future. NTSC will be the first video standard examined, followed by PAL.

NTSC format

NTSC stands for National Television System Committee, and is the analog format used by the majority of television American broadcasters. NTSC was developed in 1940 to establish a common broadcasting standard following the popularity of television and the introduction of analog television signals. NTSC images conform to a standard of an interlaced image made up of 525 horizontal lines with a refresh rate of 30 frames per second. Any standard definition picture with a maximum horizontal resolution of 720 lines and a 480 vertical resolution limit with a frame rate of 30 frames per second can be defined as NTSC and will play on a device designed for NTSC television. Numerous amounts of consumer video products, such as DVDs have been tailored to work to this standard and thus output in a resolution of 720 x 480. If a DVD uses an unsupported digital standard, many manufacturers of DVD players have implemented the ability to convert the signal to analogue and “squeeze” the image frame to fit the video.
Countries using NTSC
NTSC signals are used predominately in the Western hemisphere. The territories and some of the more notable countries that use NTSC broadcasts are listed below.
North America
Canada
Mexico
United States
Central America and the Caribbean
Costa Rica
Cuba
Guatemala
Honduras
Nicaragua
Panama
South America
Bolivia
Columbia
Peru
Asia
Burma
Japan*
Philippines
South Korea
*Japan uses a variant known as NTSC-J that has a slightly lower level of darkness.

PAL format

PAL, which stands for Phase Alternating Line, is the video standard used primarily in Europe and Africa for displaying television, DVD, and VHS pictures. The system was primarily introduced because of the inability of the 50 Hz power grids in European countries to accept the existing 60 Hz NTSC standard, and because of the colour shift that can occur during poor transmission weather. As a result, in 1963 Walter Bruch of Germany unveiled a television standard with a frequency of 50 Hz and a better quality picture than NTSC.
The PAL format outputs interlaced images at a resolution of 720 x 576 (86 more vertical lines than NTSC) with a refresh rate of 25 frames per second (5 less than NTSC). This means that while PAL broadcasts have a superior picture quality, NTSC images appear smoother, especially during high motion footage such as action films or sports.
Countries using PAL
PAL signals are most common in Europe and Africa. The territories and some of the more notable countries that use PAL broadcasts are listed below.
Africa
Nigeria
Ghana
Cameroon
South Africa
Asia
China
India
Philippines
Vietnam
Europe
Czech Republic
Denmark
Ireland
Italy
Poland
Portugal
Romania
Spain
Ukraine
United  Kingdom
South America
Argentina
Brazil
Paraguay
Uruguay
Oceania
Australia
New Zealand

The image above shows a world map of the distribution of PAL and NTSC video standards usage.
The future of NTSC and PAL
In the last few years the penetration of High Definition televisions into homes has been consistently on the rise. As a result there has been an increased amount of demand for digital signals that can contain 5.1 audio and High Definition broadcasts. Both NTSC and PAL are analog formats, which means that they have a limited bandwidth incapable of broadcasting Dolby Digital sound or High Definition images. In the near future there will be little need for these analog signals.
Numerous countries around the world have set mandates to phase out and stop any further analog broadcasts and replace them with digital high definition broadcasts. For America, on February 8th 2006 George W. Bush signed the “Digital Television Transition and Public Safety Act of 2005” into law. This set February 17th 2009 as the date when all NTSC transmissions will be turned off permanently. NTSC broadcasts will be replaced with ATSC (which stands for Advanced Television Systems Committee), a standard that will broadcast digital High Definition images.
In Europe there are already countries that have fully converted to digital signals. The countries currently using the new digital format DVB – T (Digital Video Broadcasting – Terrestrial) are listed below:
Andorra
Finland
Luxembourg
Netherlands
Sweden
Switzerland
The remainder of the European countries have all set deadlines similar to those of the United States for when PAL broadcasts will be permanently stopped.
