Here's something for broadband people that will really speed Firefox up:

1.Type "about:config" into the address bar and hit return. Scroll down and look for the following entries:

network.http.pipelining network.http.proxy.pipelining network.http.pipelining.maxrequests

Normally the browser will make one request to a web page at a time. When you enable pipelining it will make several at once, which really speeds up page loading.

2. Alter the entries as follows:

Set "network.http.pipelining" to "true"

Set "network.http.proxy.pipelining" to "true"

Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

3. Lastly right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it recieves.

If you're using a broadband connection you'll load pages MUCH faster now!

First of all copy a icon file to the root of the drive.
example: c:\icon.ico

Then create a file called: autorun.inf in c:\autorun.inf
then open that file and type the following:

[autorun]
icon=icon.ico

save and close the file.

Now open my computer and refresh.. and woh! icon changed....
you can apply to other drives too.

be careful:
"autorun.inf" and "ico.ico" must be in the root of the drive.
example: c:\autorun.inf and c:\icon.ico.
same on the root.

As you can guess with this trick you can make your folders invisible without using any software. This is a very unusual & easy trick to make your private folders invisible to others.


A folder contains two parts; an icon and a name.So to make the folder invisible you will have to make both the icon & the name invisible.

These are the steps to do that:
1. For Making The Name Invisible
Select the folder which you want to make invisible. Press F2 key then type ALT+0160 and hit enter key. You will notice that the name of the folder has become invisible. See the snapshot below.

2.For Making The Icon Invisible
Right click on the folder whose name you made invisible. Go to Properties, then go to the Customize tab. Then click on the Change Icon button. Select any blank icon there. Remember there will be many blank icons (see snapshot). Just choose any one.Click OK.

your folder is invisible now (without any software). Now only you know where the folder is located. Enjoy.

According to Microsoft corp, computers capable of running Windows Vista are classified as Vista Capable and Vista Premium Ready.

A Vista Capable or equivalent PC needs to have at minimum an 800 MHz processor, 512 MB RAM and a DirectX 9 class graphics card. A computer that meets these requirements will be capable of running all editions of Windows Vista although some of the special features and high end graphics options may require additional or more advanced hardware.

A Vista Premium Ready PC will take advantage of Vista's "high-end" features but will need at least a 1.0 GHz processor, 1 GB main memory, and an Aero-compatible graphics card with at least 128 MB graphics memory and supporting the new Windows Display Driver Model. The company also offers Windows Vista Upgrade Advisor from its website to determine the ability of a PC to run Vista in its various guises. The utility runs on Windows XP (with Service Pack 2) and Windows Vista.
Microsoft lists some Vista capable hardware on their website. The "Windows Vista Premium Ready" laptops they specify have Intel Core 2 Duo T5500 or above CPUs and 1 GB memory.

Windows Vista's "Basic" and "Classic" interfaces will work with virtually any graphics hardware that supports Windows XP or 2000; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface. As of Windows Vista Beta 2, the NVIDIA GeForce FX family and later, the ATI Radeon 9500 and later, Intel's GMA 950 integrated graphics, and a handful of VIA chipsets and S3 Graphics discrete chips are supported.Though some XGI Technology Volari chips were DirectX 9 (including the Volari V3XT which was available in PCI cards), with XGI's exit from the graphics card business it appears none of its chips are supported as of Vista Beta 2. A PCI Express (PCIe) video card is not a requirement for Windows Aero, but Microsoft recommends PCIe video over an AGP device due to the interface's greater bandwidth. There are some PCI cards available that are compatible with Windows Vista as well.

By default windows XP doesn't show the Administrator in the user list at the welcome screen. Here's a way to get around it.

Now head up to HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon\SpecialAccounts\Userlist

create a new DWORD entry and name it as Administrator and change its value to 1.

exit and reboot for the changes to take effect.
To change it back change its value to 0 or simply delete the key.

Many of us sometimes find the folder options missing in windows explorer.
Here's the solution--

Open Run and then type "gpedit.msc".
Now goto User Configuration > Administrative templates > Windows Component > Windows Explorer.
Click on Windows Explorer you will find the 3rd option on the right side of screen "Removes the Folder Option menu item from the Tools menu"
Just check it, if it is not configured then change it to enable by double clicking on it and after applying again set it to not configured.

I hopes that you will find the option after restarting windows.

One of the ways by which a virus can infect your PC is through USB/Pen drives. Common viruses such as ’Ravmon’ , ‘New Folder.exe’, ‘Orkut is banned’ etc are spreading through USB drives. Most anti virus programs are unable to detect them and even if they do, in most cases they are unable to delete the file, only quarantine it. Here are the things which you can do if you want to remove such viruses from your USB Drive

Whenever you plug a USB drive in your system, a window will appear similar to the one shown below

on’t click on Ok , just choose ‘Cancel’. Open the Command Prompt by typing ‘cmd‘ in the run box. In the command prompt type the drive letter: and press enter . Now type dir /w/a and press enter.

This will display a list of the files in the pen drive. Check whether the following files are there or not

• Autorun.inf
• Ravmon.exe
• New Folder.exe
• svchost.exe
• Heap41a
• or any other exe file which may be suspicious.

If any of the above files are there, then probably the USB drive is infected. In command prompt type attrib -r -a -s -h *.* and press enter. This will remove the Read Only, Archive, System and hidden file attribute from all the files. Now just delete the files using the command del filename. example del Ravmon.exe. Delete all the files that are suspicious. To be on a safer side, just scan the USB drive with an anti virus program to check whether it is free of virus or not. Now remove the drive and plug it again. In most of the cases, the real culprit turns out to be the “Autorun.inf” file which mostly gets executed when someone clicks Ok in the dialog window which appears above. Thus the infections can spread

Security Tip

Disable the Autoplay feature of USB drives. If you disable the Autoplay feature of USB drives, then there are lesser chances of the virus spreading. A tool which can perform such a function is Tweak UI. Download it from here install it.

Run the program. Now you can disable the Autoplay feature of the removable drives as shown above. By following the above steps, you can keep your USB drives clean.

Here is a way to disable USB ports in an Active Directory Domain


In Active Directory Users and Computers, open an existing GPO or create a new one and open it. Use the security settings of that GPO to specify which computers it affects.

In that GPO, go to Computer Configuration – Windows Settings – Security Settings – File System and create a new entry (right-click File System and select Add File). Specify the location of USBSTOR.INF (usually SystemRoot%\Inf\USBSTOR.INF)
Change the security settings of the new entry. The security settings that you specify here will be enforced on the USBSTOR.INF of every computer to which the GPO is applied. This process is not additive, which means that the previous security settings of USBSTOR.INF will be overwritten by the ones given in the GPO. It is therefore recommended to grant full control to SYSTEM and local administrators. But unlike in the default security settings of USBSTOR.INF, you should not grant any priviledges to Everybody. You do not need to explicitly deny access – just omit an entry for Everybody. Optionally, you can grant read access to a certain group. Members of this group will be able to use USB storage.

Repeat the above two steps for USBSTOR.PNF.

Download USBSTOR.ADM.

Back in the GPO, right-click Administrative Templates under Computer Configuration and select Add/Remove Templates. Click Add and browse to the location of USBSTOR.ADM. Close the dialog.

You should now have an additional entry called Services and Drivers in Administrative Templates. Click on it. If it is empty, select View from the menu and uncheck Show Policies Only. Click back on Services and Drivers in Administrative Templates. It should now show the USB Storage policy. Double click it, select Enabled and pick Disabled from the Startup Type drop down. Again, the policy must be enabled wheras Startup Type must be Disabled.
Close the dialog as well as the GPO and boot/reboot one of your workstations. Make sure no USB strorage device is connected to that computer. Log on with administrative privileges and check the permissions of USBSTOR.INF and USBSTOR.PNF. Check the value of the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor\Start. It should be 4. It is also ok if the UsbStor key doesn't exist at all.
On the same workstation, log off and back on as a user that should not have access to USB storage. Connect a USB memory stick or a similar device. Nothing should happen. Remove the memory stick.

Log on as a user that should have access to USB storage and execute net start usbstor in a command shell or at Start – Run before connecting the memory stick. The memory stick should initialized and mapped to a drive letter. If USBSTOR fails to start, it's probably because this is the first time a memory stick is plugged into the workstation in which case USBSTOR is not yet installed. Nevertheless, the memory stick should be initialized and mapped correctly but you need to reboot in order to reapply the administrative template such that USBSTOR is disabled again. Alternatively, you can disable it manually by downloading and double clicking USBSTOR.REG as well as executing net stop usbstor.

Instruct the users with access to USB storage that they need to execute net start usbstor before they can connect a USB storage device.
