How to Protect your E-Mail from spam

Imagine yourself preparing an important presentation. Suddenly, the Outlook Express installed on your computer pops up a message saying 'Buy Viagra for cheap' or 'Trying to sell you a business that pays you thousands of $$ every week'. Most Internet users are familiar with such unwanted emails in their Inbox.
Lately, however, you must have noticed an increase in this kind of 'junk mail' to your your email address, or on your favourite newsgroup. These junk mails, also known as spam, are flooding the Internet with many copies of the same message, in an attempt to force it on people who would otherwise choose not to receive it. Most spam is commercial advertising, often for dubious products like get-rich-quick schemes. Spam costs the sender very little -- most of the cost is paid for by the recipient or the carriers, rather than by the sender.
Email spam targets individual users with direct mail messages. Email spam lists are often created by scanning Usenet postings, stealing Internet mailing lists, or searching the Web for addresses. Here are some tips and tricks to help you control the amount of spam you receive.
How to eliminate spam:
1. Try not to display your email address in public: This includes newsgroup postings, chat rooms, Websites and online services membership directories. You may want to opt out of member directories for your online services -- spammers use them to harvest addresses. Also, disguise your email address when you post it to a newsgroup, chat room, bulletin board, or other public web pages. For example, use ankurjain_del AT rediffmail DOT com. This way, a person can interpret your address, but the automated programmes spammers use often cannot.
2. Check the privacy policy when you submit your address to a Website: See if it allows the company to sell your address. You may want to opt out of this provision, if possible, or not submit your address at all to Websites that won't protect it. Also, look for all the check boxes that have been checked by default while you fill and submit any form.
3. Use two email addresses: Try to use two email addresses -- one for personal messages and one for newsgroups and chat rooms. You also might consider using a disposable email address service -- this can be a separate email address that forwards mails to your permanent account. If one of the disposable addresses begins to receive spam, you can shut it off without affecting your permanent address.
4. Use a unique email address: Your choice of email addresses may affect the amount of spam you receive. Spammers use 'dictionary attacks' to sort through possible name combinations at large ISPs or email services, hoping to find a valid address.. Thus, a common name such as ankurjain may get more spam than a more unique name like a11nkur2006jain. Of course, there is a downside -- it's more difficult to remember an unusual email address.
5. Use an email filter: Check your email account to see if it provides a tool to filter out potential spam or a way to channel spam into a bulk email folder. You might want to consider these options when you're choosing your Internet Service Provider. Do your part by keeping your junk email filter up-to-date.
6. Never hit the 'REMOVE' button: Most spam mail you receive contains a line that says 'Reply with subject line as UNSUBSCRIBE to remove your email address from our mailing list'. When, in fact, you reply to unsubscribe, what happens is that you simply verify you have a valid email address. As a result, you get even more spam instead of getting removed from the list.. Some spam relies on generators that try variations of email addresses at certain domains. If you click a link within an email message or reply to a certain address, you are only confirming your email address is valid. Unwanted messages that offer an 'unsubscribe' option are particularly tempting, but this is often just a method for collecting valid addresses that are then sent other spam.

Take, for example, the : URL: http://grz67. com/track/ rd/3964715/ 5751/23643/ 1934. This URL contains a tracking ID will be mapped to your email ID in the site's database. The spammers would be sending you email with this URL behind the link. Whenever the user accesses this URL, the spammer can be sure the email address associated with this tracking ID is a valid one. Many people have documented the fact that not only do 'Remove' lists not work, they verify to the spammer that your e-mail address is good. The spammer then puts it on a premium CD and sell it to the next spammer for even more money.
7. Be responsible and considerate as a user: We ourselves promote spam in some way or the other. Some people consider email forwards a type of spam, so be selective with the messages you redistribute. Don't forward every message to everyone in your address book. If someone asks that you not forward messages to him or her, respect their request.
8. Keep your antivirus programs updated: Spam is a cat-and-mouse game, with spammers working relentlessly to outwit the filters. There have been some viruses reported, which help in spamming by sending a pre-set mail to all your Outlook contacts using your email address. When the recipients open their mail, their system also gets infected and mails are sent from their system to all the contacts in their address books. So, by keeping your antivirus programme updated, you can detect these viruses, stop their entry into your computer and prevent spamming from your mailbox.

How to disable "In Private" browsing in IE 8

Microsoft got lots of praise from privacy advocates for including the "In Private" mode in Internet Explorer 8, which lets you surf without storing cookies, saving history or cache information or otherwise leaving tracks of what sites you've visited. This is good when using public computers - but some parents have written to say they don't want their kids to be able to so easily erase the traces of where they've been on the family computer. Well, if you're one of those, you'll be happy to know that it's pretty easy to disable "In Private" browsing. Here's how to do it in Vista Business, Enterprise or Ultimate or in the Windows 7 RC:
  1. Click Start and in the Search box, type gpedit.msc to open the local Group Policy management console.
  2. In the left pane, navigate to Computer Configuration Administrative Templates Windows Components Internet Explorer InPrivate
  3. In the right pane, double click the setting "Turn off InPrivate browsing"
  4. Select Enabled and click OK to prevent the use of the In Private feature.

Is there any reason to run 64 bit Vista on a system that maxes out at 4 GB RAM?

The biggest advantage of 64 bit over 32 bit is the ability to use large amounts of RAM. The 32 bit OS is limited to 4 GB but 64 bit Vista can support from 8 to 128 GB depending on the edition (Home Premium supports 16 GB and Ultimate supports 128). However, you can only use as much RAM as your computer's motherboard will support, so if the hardware limits you to 4 GB, the 64 bit OS won't help you memory-wise. In fact, it may hurt you a little, since 64 bit Vista can use about 12 - 15% more RAM for the OS and services.

I have found 64 bit Windows to be generally more stable than 32 bit on the same machine, but that advantage can be outweighed by the fact that it's harder to find 64 bit hardware drivers, so some of your peripherals may not work. If a driver isn't signed, you can't load it on the 64 bit OS. This is probably one reason for the extra stability, but again makes it more likely you won't be able to use some of your devices. Another consideration is that 64 bit Vista won't run 16 bit applications. So if you still have a few old 16 bit apps you want to run, the only way you'll be able to do that is to install a 32 bit OS in a virtual machine and run them there.

You also have a performance advantage when you run 64 bit programs on the 64 bit OS. Unfortunately, right now there aren't many 64 bit applications; however, Microsoft Office 2010 will be available in a 64 bit version. Overall, though, with a machine with limited RAM, you're probably better off sticking with the 32 bit OS.

How to get your Gmail messages in Windows Mail

You can get the messages sent to your Gmail account without going to the Gmail web site - just set up Windows Mail in Vista to get them. First, you need to enable IMAP on the Settings page on the Gmail web site. Just click "Enable IMAP" in the "IMAP Access" section.
Now in Windows Mail, do the following:
  1. Click Tools Accounts and select "E-mail account" as the account type.
  2. Enter your display name, then in the next box, enterer your Gmail address.
  3. On the "Set up email servers" page, choose IMAP for the incoming email server type in the drop-down box, then enter "imap.gmail.com" as the incoming server and "smtp.gmail.com" as the outgoing server.
  4. Check the box "Outgoing server requires authentication."
  5. On the next page, enter your gmail address (username) and password. Check the box that says "do not download my email and folders at this time."
  6. Click Finish.
  7. On the Internet Accounts dialog box, highlight the name of the gmail account and click Properties.
  8. Click the Advanced tab, and check the options "this server requires a secure connection (SSL). Set the outgoing mail (SMTP) port to 587 and the incoming mail (IMAP) port to 993.
  9. Click the IMAP tab and uncheck "Store special folders on IMAP server."

You can now configure which folders you want Windows Mail to download by clicking imap.gmail.com in the left pane of the mail client window. You probably won't wat to download your spam folder and your trash folder, for example. You can now click the Send/Receive button to download your mail.

How to enter the BIOS or CMOS setup.

Because of the wide variety of computer manufacturers and BIOS manufacturers over the evolution of computers, there have been numerous different ways to enter the BIOS or CMOS Setup. Below is a listing of the majority of these methods as well as other recommendations for entering the BIOS setup.

Computers that have been manufactured in the last few years will allow you to enter the CMOS by pressing one of the below five keys during the boot. Usually it's one of the first three.
  • F1
  • F2
  • DEL
  • ESC
  • F10
A user will know when to press this key when they see a message similar to the below example as the computer is booting. Some older computers may also display a flashing block to indicate when to press the F1 or F2 keys.

Press to enter BIOS setup

Tip: If your computer is a new computer and you are unsure of what key to press when the computer is booting, try pressing and holding one or more keys the keyboard. This will cause a stuck key error, which may allow you to enter the BIOS setup.

Where is the Vista Start Menu folder?

QUESTION:
I recently bought a computer with Vista installed. I like it for the most part but I'm still confused about some things that were changed. In XP, I could go to Documents and Settings, Default User, Start Menu and remove things from the start menu. I can find it in Vista. Is there still a way to do this? Thanks!
ANSWER:
Vista has changed the path for that data; it's now in the Users folder instead of Documents and Settings.
The full path is: Users \ Default \ AppData \ Roaming \ Microsoft \ Windows \ Start Menu
If you want to modify the Start Menu for your own user account (rather than all users), there's an easy way. In the Search box on the Start menu, just type: shell:start menu

How to disable the Caps Lock key?

Do you ever actually use the Caps Lock key? I can't remember the last time I did. But it hasn't been nearly that long since the last time I accidentally hit it and ended up with all caps that I didn't want. That can be a real problem with some laptops whose keys so small that you hit Caps Lock when you're trying for Shift or Tab. Want to disable it? Here's how:
  1. Open your registry editor and navigate to the following key: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Keyboard Layout
  2. In the right pane, double click the value Scancode Map. If it doesn't exist, create a new Binary Value and name it "Scancode Map" (without the quotation marks).
  3. Enter the following binary data in the value data field: 00000000 00000000 0200000000 00003A00 00000000
  4. Close the registry editor.

This remaps the key to "nothing." You can also remap it to serve the function of another key, such as the SHIFT key. If you often hit Caps Lock when you really want SHIFT, you might want to do this. In that case, enter the following value in the value data field: 00000000 00000000 02000000 2A003A00 00000000

How to make XP look and act like Windows 7

No, you can't turn XP into Win7; you can't even do a direct upgrade. However, if you like the sleek look of 7 but aren't ready to start over with a new OS, you can give your XP computer much the same look, and you can also download programs that will provide some of the same functionality as new Windows 7 features.

  1. Install the Windows 7 Taskbar iconizer to make the taskbar icons look more like those in 7.
  2. Install AeroPeek and Visual Task Tips to allow you to view thumbnails of open windows and highlight the active window while making all the other windows transparent (requires .NET Framework 3.5)
  3. Install AeroSnap to make windows automatically resize to fill half the screen when dragged to the side of the monitor.
  4. Download and run AeroShake to minimize all inactive windows by shaking with your mouse.

You can find links to download all of these programs, along with screenshots and more instructions, at make-windows-xp-vista-like-windows

“Your system is low on virtual memory” error message when you try to start an Office program

SYMPTOMS
When you start any of the Microsoft Office 2007 or Microsoft Office 2003 programs, you may receive an error message that is similar to the following error message:

Your system is low on virtual memory. To ensure that Windows runs properly, increase the size of your virtual memory paging file. For more information, see Help.

If you click OK, you may receive the following error message:

Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied. For more information, see Help.

CAUSE
This behavior may occur if you try to start any of the programs included in Office on a computer where the paging file value setting is too low.

RESOLUTION
To resolve this behavior, increase the size of the paging file. To do so, follow these steps as appropriate for your operating system.Note Microsoft Office 2007 requires Windows XP or higher.
FOR WINDOWS XP
  1. Click Start, right-click My Computer, and then click Properties.
  2. In the System Properties dialog box, click the Advanced tab.
  3. In the Performance pane, click Settings.
  4. In the Performance Options dialog box, click the Advanced tab.
  5. In the Virtual memory pane, click Change.
  6. Change the Initial size value and the Maximum size value to a higher value, click Set, and then click OK.
  7. Click OK to close the Performance Options dialog box, and then click OK to close the System Properties dialog box.

NOTE:
With virtual memory, the computer can use hard disk space as random access memory (RAM). The computer uses virtual memory to augment the ordinary RAM that is installed on the computer. If you reduce the size of the paging file, the Office program may not start correctly or may not start at all. This behavior may occur even if the computer has a large RAM.

How to install Windows 7 to dual boot with XP

Many people who have stuck with XP are getting the itch to give Windows 7 a try - but without making a commitment. Here's the procedure for installing 7 to dual boot with XP on a computer that already has XP installed:

1.If you only have one partition on your hard drive, you need to shrink it so you can create a second one on which to install Windows 7 (I recommend if you have less than 30 GB of free space, you should buy and install a second physical hard drive on which to install Win7).

2. Boot the system from the Windows 7 installation DVD and when you get to the "Where do you want to install Windows?" option, be sure to pick the partition, disk or unallocated space on which XP is not installed. Proceed through the Setup process.

3. Proceed through the Setup process

4. When the system reboots after installing, pick "Earlier Version of Windows" from the boot menu to boot into XP.
If you had XP installed on C:, when you boot into Windows 7 you'll see that it appears to be installed on C:. Don't panic - Windows 7 calls whatever drive it's installed on C:, which actually makes things easier for applications. The drive on which XP is installed won't show up at all by default, although it's there in Disk Management and you can assign it a drive letter if you want it to show up when you're in Win7 (for example, if it has data stored on it that you want to access). For example, you might assign it drive letter X: to denote that it's the XP drive, and you'll see it as X: in Win7 Explorer. However, when you boot back into XP, the drive it's installed on will be C: (or whatever it was originally) again.

Here's a detailed, illustrated tutorial on installing the dual boot configuration:
