How to Disable UAC / Turn Off UAC in Windows 7

User account control (UAC) a new feature which was introduced in Microsoft windows vista has become moreannoying feature. UAC in windows vista is way toprotected windows operating system by preventing unauthorized changes to your system. However UAC inWindows 7 is less annoying and more friendlier now.

Windows 7 UAC has option to set level of alerts and notification hence virtually no setting toturnoff or disable UAC in windows 7.well actually the steps for disabling UAC in windows 7 is more or less similar to windows vista.

Method 1: Disable and Turnoff UAC in Windows 7 from Control Panel

1. Access User Control Panel from Start Menu -> Control Panel -> User Accounts and Family Safety -> User Account

2. Click on

User Account Control settings link.

3. Move the Slider to Never Notify

4. Click OK to make the change effective

5. Reboot.

Method 2: Disable UAC with Registry Editor (Regedit) in Windows 7

1. Run Registry Editor (RegEdit) by typing regedit at command prompt or at startmenu->run

2. Locate following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System

3. Locate the following REG_DWORD value:

EnableLUA

4. Set the value of EnableLUA to 0.

Optional step to suppress UAC permission prompt dialog,

1. Locate the following REG_DWORD value:

ConsentPromptBehaviorAdmin

2. Set the value of ConsentPromptBehaviorAdmin to 0 (optional).

Now Exit from Registry Editor and Restart the computer.

What is difference between Switch and Hub.

Although hubs and switches both glue the PCs in a network together, a switch is more expensive and a network built with switches is generally considered faster than one built with hubs.

Why?

When a hub receives a packet (chunk) of data (a frame in Ethernet lingo) at one of its ports from a PC on the network, it transmits (repeats) the packet to all of its ports and, thus, to all of the other PCs on the network. If two or more PCs on the network try to send packets at the same time a collision is said to occur. When that happens all of the PCs have to go though a routine to resolve the conflict. The process is prescribed in the Ethernet Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol. Each Ethernet Adapter has both a receiver and a transmitter. If the adapters didn't have to listen with their receivers for collisions they would be able to send data at the same time they are receiving it (full duplex). Because they have to operate at half duplex (data flows one way at a time) and a hub retransmits data from one PC to all of the PCs, the maximum bandwidth is 100 Mhz and that bandwidth is shared by all of the PC's connected to the hub. The result is when a person using a computer on a hub downloads a large file or group of files from another computer the network becomes congested. In a 10 Mhz 10Base-T network the affect is to slow the network to nearly a crawl. The affect on a small, 100 Mbps (million bits per scond), 5-port network is not as significant.

Two computers can be connected directly together in an Ethernet with a crossover cable. A crossover cable doesn't have a collision problem. It hardwires the Ethernet transmitter on one computer to the receiver on the other. Most 100BASE-TX Ethernet Adapters can detect when listening for collisions is not required with a process known as auto-negotiation and will operate in a full duplex mode when it is permitted. The result is a crossover cable doesn't have delays caused by collisions, data can be sent in both directions simultaneously, the maximum available bandwidth is 200 Mbps, 100 Mbps each way, and there are no other PC's with which the bandwidth must be shared.

An Ethernet switch automatically divides the network into multiple segments, acts as a high-speed, selective bridge between the segments, and supports simultaneous connections of multiple pairs of computers which don't compete with other pairs of computers for network bandwidth. It accomplishes this by maintaining a table of each destination address and its port. When the switch receives a packet, it reads the destination address from the header information in the packet, establishes a temporary connection between the source and destination ports, sends the packet on its way, and then terminates the connection.

Picture a switch as making multiple temporary crossover cable connections between pairs of computers (the cables are actually straight-thru cables; the crossover function is done inside the switch). High-speed electronics in the switch automatically connect the end of one cable (source port) from a sending computer to the end of another cable (destination port) going to the receiving computer on a per packet basis. Multiple connections like this can occur simultaneously. It's as simple as that. And like a crossover cable between two PCs, PC's on an Ethernet switch do not share the transmission media, do not experience collisions or have to listen for them, can operate in a full-duplex mode, have bandwidth as high as 200 Mbps, 100 Mbps each way, and do not share this bandwidth with other PCs on the switch. In short, a switch is "more better."

How to know Our Sent eMail is Read or Not?

If you ever wondered whether mails you sent ever gets read or just sent to trash, you can use a mail tracking service which allows email tracking provided by MailTracking.Com. They send you a email notification whenever the recipient reads your email. Notification includes many details including following… Date and time opened, Location of recipient (per their ISP city /town),How long the email was read for? , How many times your email was opened , If your email was forwarded, or opened on a different computer etc

How to Use Mail Tracking to Track your Emails Create an account with them first.

Then next time, whenever you send mail to someone@special.com just add .mailtracking.com to the email address.

So in this case email address will become someone@special.com.mailtracking.com

Now whenever someone@special.com read your email, you will receive notification mail from mailtracking.com

Details : Basically the change in email address will route email through mailtracking.com’ server. They add a small (around 3×3 pixel) white image which is almost invisible to human eyes in email body. The image will be hosted on mailtracking servers and a unique image is kept for each email message.

So when someone opens email that image also get downloaded. Now mailtracking server logs the browser request for image (note that the request goes in background) and thus can mail you details which mentioned above.

Who is accessing your Windows Shared Folders?

If you have two or more computers connected on to the same network, you can share files and folders on your computer such that others may access them as if they were on their own local file system. You may also set permissions depending on whether you others to simply view your files or even modify them.

This support page on Microsoft has more details on file sharing in Windows.

Once you have enabled sharing in Windows, you may also monitor connections to know which other

computers are accessing files on your computer and what files /folders are they currently accessing.

The easiest way to monitor this activity is through the Computer Management program that you may quickly access by typing compmgmt.msc in the Windows Run box. Once there, go to System Tools –> Shared Folders –> Sessions to view a list of all users who are connected over the network to your computer and what files are they accessing.

Alternatively, if you need something more simple, here’s a tiny utility called NetShare Monitor that does exactly the same thing but in a less complicated manner.

NetShare Monitor displays a list of users who are currently accessing your files and folders and also keeps a detailed log of all files that they may have accessed in the session. The audio alerts and the flashing icon in the system tray aren’t very pleasing but luckily, you can easily turn them off from the setting box.

Simple ways to increase your computer’s performance – Save hard disk space! Tips

        

             Do you have a computer that doesn’t have a huge hard drive, but you store a lot of pictures, videos, or other large files that’s getting your free space low? Once your computer gets low on hard disk space, normal processes begin to slow down and your computer will run painfully slow. There are of course lots of other reasons why your computer might be running slowly, but this post is specifically for those who know they are running short on disk space.

So instead of having to delete files or move things off to USB sticks or external hard drives, you can first try to free up some space on your computer that may be taken up by useless temporary files or system processes. There are usually three big space “killers” in Windows that are set by default to hog disk space and should be reined in as soon as you can!

1. Recycle Bin – Why pick on the Recycle Bin eh?? The never-irritating and sometimes life-saving trash can just sits there waiting for us to tell it what to do right? Well, it also takes up a LOT of space that it doesn’t need. The recycle bin uses a percentage of your hard drive in order to store deleted files. However, this percentage is set by default at a very high number and ends up wasting a lot of space.

Here’s how to fix space killer #1. First right click on the Recycle Bin on your desktop and click Properties.

On the Global tab, you can choose Use one setting for all drives or Configure drives independently. It’s usually better to configure the recycle bin for each drive independently since it’s based on the size of the drive, so 5% of a 50GB hard drive is much bigger than 5% of a 20GB hard drive. At the top you’ll see tabs for each partition you have on your computer.

By default, the slider bar is usually set at something like 12%, which is very high! Unless you are deleting huge files, there will never be a need for a recycle bin that size. A good size is from anywhere between 3 to 5% of your hard drive. Drag the slider bar and you just saved yourself a good amount of space, especially if you have large hard drives. My computer is set to 1% and I’ve never had a problem recovering a file from the bin!

2. Turn Off System Restore – Another handy little service that can get your computer back up and running sometimes, but again takes up a lot of extra space that is not needed. Also, System Restore only recovers Windows files, not any of your data. So having System Restore enabled on any other drive other than your C drive (where Windows is installed) is completely useless.

To fix this one, right click on My Computer and choose Properties.

Click on the System Restore tab.

As you can see from my computer, I have a C and a D drive of which system restore has been turned off on D. Again, this is because System Restore does not protect your data, it only protects Windows system files, so you don’t need it for any other drive other than the main system drive. If you click on the C drive and choose settings, you’ll get the dialog box to set the amount of space.

For system restore, a value between 2% to 4% will be fine. The default 12% wastes loads and loads of space! I have mine set to 2% and even with that, I still have over 10 restore points to recover from if I needed to.

3. Delete temporary Internet Explorer files – Ahhh…if you like to browse the Internet hardcore like I do, then you MUST clean out your temporary files every once in a while or else it will take up lots of space. And again, as with the Recycle Bin and System Restore, we can set the max size for the amount of storage for temporary Internet files. And again, it’s set really high by default!

Open IE and go to Tools, Internet Options.

On the options dialog, under Browsing History, click on Settings.

Now here you can type in a value for the amount of space to be used!! When I first did mine, it was set to 1GB!!! So I had 1 whole GB of storage being used by temporary files that were never going to be used again anyway! Change that value to something very small like 25MB or even less if you like. After doing this, you should click Delete under the Browsing History section and delete all of the current data there.

4. Actually, there is a 4th thing you can do to get some disk space back! If you’re like most people, you probably use StandBy mode on your computer by simply closing the cover or pressing the power button. No one really uses Hibernate mode because why use that when you can use StandBy, which is easier and a lot faster! I personally have never used it and don’t think I ever will, but it takes up a good amount of space on your computer.

Go to Start, Control Panel and choose Power Options. If you are in Category view, click Switch to Classic View at the top left. Then click on the Hibernate tab in the Power Options dialog:

Make sure it’s unchecked. The hibernate feature takes up the amount of space equal to your RAM, so in my case I was wasting another 1GB of space!!!

Now you hopefully just saved yourself a couple of GB’s worth of space! Now you can last a little bit longer before having to move stuff off.
