Load Applications Faster...

2011-02-07T17:43:00.000+05:30

The Windows prefetcher aims to load applications faster by
“pre- fetching” the application and storing it in the pre-fetch cache.
You can speed up application loading by changing the default value of one
the settings under the relevant key.

Navigate to:

HLM > SYSTEM > CurrentControlSet > Control > Session Manager > Memory Management > PrefetchParameters

The default value for the EnablePrefetcher setting is 3. Change this value to 5 to make applications load faster. You can experiment with higher values upto 9 and see if you get a further improvement.

Since this relates to the system, a reboot is required for the change to take effect.

Unable to delete a file? Must see this..

2011-02-07T17:11:00.000+05:30

Were you ever unable to delete a file?..you click delete and a message like this or like this occurs.

That is when windows are using the program in that instance and the program needs to be shut down. So we go to Task Manager>Processes and find the process and end it.

But what if that process is already ended and we still have the same message appearing over and over again. That happens when Windows still use one of the threads of the process but not the whole process. So, if the process/program is not essential for the OS then we can just delete the file through command prompt:

1.Remember where the file is located

2.Click ctrl-alt+delete and end explorer from the process list…Once you removed explorer Windows will not be able to see what exactly are you doing with the files.

3.Click File and New task. Type in cmd

4.Now when you open cmd, the navigator is probably located in c:\Document and Settings\Username

5.We need to navigate from this folder to the folder where the file is…Using commands cd .. to go up and cd foldername to enter a designated folder

6.Once we’re in the desired folder, by using the dir command we can see all the files in the folder .

7. By typing in del foldername prompt will delete the file.

8.Now just type in explorer.

*it’s important to know that the file you’re deleting is not essential to the functioning of the OS

20 things you didn't know about Windows XP

2011-02-07T16:43:00.000+05:30

You've read the reviews and digested the key feature enhancements and operational changes. Now it's time to delve a bit deeper and uncover some of Windows XP's secrets.

1. It boasts how long it can stay up. Whereas previous versions of Windows were coy about how long they went between boots, XP is positively proud of its stamina. Go to the Command Prompt in the Accessories menu from the All Programs start button option, and then type 'systeminfo'. The computer will produce a lot of useful info, including the uptime. If you want to keep these, type 'systeminfo > info.txt'. This creates a file called info.txt you can look at later with Notepad. (Professional Edition only).

2. You can delete files immediately, without having them move to the Recycle Bin first. Go to the Start menu, select Run... and type 'gpedit.msc'; then select User Configuration, Administrative Templates, Windows Components, Windows Explorer and find the Do not move deleted files to the Recycle Bin setting. Set it. Poking around in gpedit will reveal a great many interface and system options, but take care -- some may stop your computer behaving as you wish. (Professional Edition only).

3. You can lock your XP workstation with two clicks of the mouse. Create a new shortcut on your desktop using a right mouse click, and enter 'rundll32.exe user32.dll,LockWorkStation' in the location field. Give the shortcut a name you like. That's it -- just double click on it and your computer will be locked. And if that's not easy enough, Windows key + L will do the same.

4. XP hides some system software you might want to remove, such as Windows Messenger, but you can tickle it and make it disgorge everything. Using Notepad or Edit, edit the text file /windows/inf/sysoc.inf, search for the word 'hide' and remove it. You can then go to the Add or Remove Programs in the Control Panel, select Add/Remove Windows Components and there will be your prey, exposed and vulnerable.

5. For those skilled in the art of DOS batch files, XP has a number of interesting new commands. These include 'eventcreate' and 'eventtriggers' for creating and watching system events, 'typeperf' for monitoring performance of various subsystems, and 'schtasks' for handling scheduled tasks. As usual, typing the command name followed by /? will give a list of options -- they're all far too baroque to go into here.

6. XP has IP version 6 support -- the next generation of IP. Unfortunately this is more than your ISP has, so you can only experiment with this on your LAN. Type 'ipv6 install' into Run... (it's OK, it won't ruin your existing network setup) and then 'ipv6 /?' at the command line to find out more. If you don't know what IPv6 is, don't worry and don't bother.

7. You can at last get rid of tasks on the computer from the command line by using 'taskkill /pid' and the task number, or just 'tskill' and the process number. Find that out by typing 'tasklist', which will also tell you a lot about what's going on in your system.

8. XP will treat Zip files like folders, which is nice if you've got a fast machine. On slower machines, you can make XP leave zip files well alone by typing 'regsvr32 /u zipfldr.dll' at the command line. If you change your mind later, you can put things back as they were by typing 'regsvr32 zipfldr.dll'.

9. XP has ClearType -- Microsoft's anti-aliasing font display technology -- but doesn't have it enabled by default. It's well worth trying, especially if you were there for DOS and all those years of staring at a screen have given you the eyes of an astigmatic bat. To enable ClearType, right click on the desktop, select Properties, Appearance, Effects, select ClearType from the second drop-down menu and enable the selection. Expect best results on laptop displays. If you want to use ClearType on the Welcome login screen as well, set the registry entry HKEY_USERS/.DEFAULT/Control Panel/Desktop/FontSmoothingType to 2.

10. You can use Remote Assistance to help a friend who's using network address translation (NAT) on a home network, but not automatically. Get your pal to email you a Remote Assistance invitation and edit the file. Under the RCTICKET attribute will be a NAT IP address, like 192.168.1.10. Replace this with your chum's real IP address -- they can find this out by going to www.whatismyip.com -- and get them to make sure that they've got port 3389 open on their firewall and forwarded to the errant computer.

11. You can run a program as a different user without logging out and back in again. Right click the icon, select Run As... and enter the user name and password you want to use. This only applies for that run. The trick is particularly useful if you need to have administrative permissions to install a program, which many require. Note that you can have some fun by running programs multiple times on the same system as different users, but this can have unforeseen effects.

12. Windows XP can be very insistent about you checking for auto updates, registering a Passport, using Windows Messenger and so on. After a while, the nagging goes away, but if you feel you might slip the bonds of sanity before that point, run Regedit, go to HKEY_CURRENT_USER/Software/Microsoft/Windows/Current Version/Explorer/Advanced and create a DWORD value called EnableBalloonTips with a value of 0.

13. You can start up without needing to enter a user name or password. Select Run... from the start menu and type 'control userpasswords2', which will open the user accounts application. On the Users tab, clear the box for Users Must Enter A User Name And Password To Use This Computer, and click on OK. An Automatically Log On dialog box will appear; enter the user name and password for the account you want to use.

14. Internet Explorer 6 will automatically delete temporary files, but only if you tell it to. Start the browser, select Tools / Internet Options... and Advanced, go down to the Security area and check the box to Empty Temporary Internet Files folder when browser is closed.

15. XP comes with a free Network Activity Light, just in case you can't see the LEDs twinkle on your network card. Right click on My Network Places on the desktop, then select Properties. Right click on the description for your LAN or dial-up connection, select Properties, then check the Show icon in notification area when connected box. You'll now see a tiny network icon on the right of your task bar that glimmers nicely during network traffic.

16. The Start Menu can be leisurely when it decides to appear, but you can speed things along by changing the registry entry HKEY_CURRENT_USER/Control Panel/Desktop/MenuShowDelay from the default 400 to something a little snappier. Like 0.

17. You can rename loads of files at once in Windows Explorer. Highlight a set of files in a window, then right click on one and rename it. All the other files will be renamed to that name, with individual numbers in brackets to distinguish them. Also, in a folder you can arrange icons in alphabetised groups by View, Arrange Icon By... Show In Groups.

18. Windows Media Player will display the cover art for albums as it plays the tracks -- if it found the picture on the Internet when you copied the tracks from the CD. If it didn't, or if you have lots of pre-WMP music files, you can put your own copy of the cover art in the same directory as the tracks. Just call it folder.jpg and Windows Media Player will pick it up and display it.

19. Windows key + Break brings up the System Properties dialogue box; Windows key + D brings up the desktop; Windows key + Tab moves through the taskbar buttons.

20. The next release of Windows XP, codenamed Longhorn, is due out late next year or early 2003 and won't be much to write home about. The next big release is codenamed Blackcomb and will be out in 2003/2004.

Boot Defragment

2011-02-07T16:39:00.000+05:30

A very important new feature in Microsoft Windows XP is the ability to do a boot defragment. This basically means that all boot files are placed next to each other on the disk drive to allow for faster booting. By default this option is enabled but some upgrade users have reported that it isn't on their setup.

1. Start Regedit.
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
3. Select Enable from the list on the right.
4. Right on it and select Modify.
5. Change the value to Y to enable and N to disable.
6. Reboot your computer.

2011-02-07T16:37:00.000+05:30

1 Open Control Panel
2. Click on Performance and Maintenance.
3. Click on System.
4. Then click on the Advanced tab
5. Click on the error-reporting button on the bottom of the windows.
6. Select Disable error reporting.
7. Click OK
8. Click OK

XP Animations

2011-02-07T16:34:00.000+05:30

You can turn off window animation ("exploding" windows), displayed when you play around with minimizing/maximizing open windows. This makes navigating Windows 95/98/ME/NT4/2000/XP a lot quicker, especially if you don't have a fast video controller, or if you got tired of seeing it all the time (like I did).

To do this, run Regedit (or Regedt32) and go to:

HKEY_CURRENT_USER | Control Panel | Desktop | WindowMetrics

or if you are the only user of your Windows computer go to:

HKEY_USERS | .Default | Control Panel | Desktop | WindowMetrics

Right-click on an empty spot in the right hand pane. Select New -> String [REG_SZ] Value. Name it MinAnimate. Click OK. Double-click on "MinAnimate" and type 0 to turn OFF window animation or 1 to turn it ON. Click OK. Close the Registry Editor and restart Windows. Done.

TweakUI, the famous Microsoft Power Toy [110 KB, free, unsupported] can also turn off animated windows.
Just remove the check mark from the "Window Animation" box under the General tab.
