How to Boost and Increase Your Internet Speed

                                     Increase Internet Speed

 Need to increase your Internet connection speed/ There are a number of tweaks out there that will enable you to maximize your system’s performance and likewise, there are lots of things you can do to tweak your Internet connection to boost Internet speed. There are tons of them out there, but this article just lays out two of the most useful ones.

Tweak 1: Un-reserving bandwidth

By Default, XP reserves 20% of your bandwidth for it’s own use. This is a crying shame and should be undone immediately. To do this, you will not require any additional software, just follow the steps below.

1. Access the Group Policy Editor. This can be done by typing gpedit.msc in the Run box (Start, and then Run). You will now be looking at something like this.
   
   
   
2. Navigate to Computer Configuration/Administrative Templates/Network/QOS Packet Scheduler using the pane on the left side.
3. In the left pane, there should be a Setting with the name Limit reservable bandwidth, right-click this and select properties.
4. Now this might seem a bit weird, as the State will say “Not Configured” but Windows by default will reserve 20%. So the trick is to set it to reserve 0%. You can do this by clicking enabled and then setting the Bandwidth Limit % to 0. It should look like the image below.
   
   
   
5. Hit OK then close the Group Policy Editor.

That’s it! You’re done with the first tweak. Just a quick side note here, there are lots of other little things you can change easily using the policy editor. Feel free to wander around!

Tweak 2: Optimizing TCP/IP settings

This next tweak is going to require a piece of freeware called SG TCP Optimizer. This nifty little utility will optimize the manner in which your PC sends and receives data packets, which will as a result speed up your connection. Though It is most effective for broadband connections, it works for just about any type of connection.

1.  Download SG TCP Optimizer. You don’t need to install it, just double-click and it will run. Once you run it, you should be looking at this :
   
2. That is quite an intimidating interface, but we won’t be touching most of it. Under the General Settings tab, just drag the slider to match your connection’s download speed. Then, at the bottom of the same window, select the “Optimal Settings” radio button and click “Apply Changes”.
3. You will now be looking at a window like the one below.
   
   
   
4. Make sure that the “Backup” tick box is ticked and then click OK.
5. All that’s left is to reboot your system, in order to apply the changes. You will be prompted to do so.
6. Once your system has rebooted, surf around for a while. If for whatever reason you feel your connection has been affected negatively, then fear not, for the changes you made can be undone. Start SG TCP Optimizer, click File and choose restore backed up settings. This will bring up a dialog box where you can navigate to where you downloaded the program. There, you will find a file with the extension .spg with a filename containing the date.
   For example If you applied the changes on the 21st of February “sg_backup_2008-02-21-xxxx.spg” would be the filename, where the xxxx is any number. Once you find this file select it and press open. This should bring to a dialog box similar to the one shown above. Click OK and reboot. Your original settings are now restored.

There you have it. Your connection is now tweaked and ready to go! Any questions, post a comment!

How to make a computer faster

                                  6 ways to speed up your PC

 

By following a few simple guidelines, you can maintain your computer, help increase its speed, and help keep it running smoothly. This article discusses how to use the tools available in Windows 8, Windows 7, Windows Vista, and Windows XP Service Pack 3 to help make your computer faster, maintain your computer efficiently, and help safeguard your privacy when you're online.

Note: Some of the tools mentioned in this article require you to be logged on as an administrator. If you aren't logged on as an administrator, you can only change settings that apply to your user account.

1. Remove spyware, and help protect your computer from viruses

Spyware collects personal information without asking for permission. From the websites you visit to user names and passwords, spyware can put you and your confidential information at risk. In addition to compromising your privacy, spyware can hamper your computer's performance. Fortunately, there are a couple of easy ways to combat spyware.
Download Microsoft Security Essentials for free to help guard your system from viruses, spyware, adware, and other malicious software (also known as malware). Microsoft Security Essentials acts as a spyware removal tool and includes automatic updates to help keep your system protected from emerging threats.
The Microsoft Windows Malicious Software Removal Tool, also free, checks computers running Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000, Windows Server 2012, Windows Server 2008, and Windows Server 2003 for infections by specific, prevalent malicious software, including Folstart, Phorpiex, Weelsof, Blaster, Sasser, and Mydoom. It helps remove any detected infection or malware.

2. Free up disk space

The Disk Cleanup tool helps you to free up space on your hard disk to improve the performance of your computer. The tool identifies files that you can safely delete and lets you choose to delete some, all, or none of the identified files.
Use Disk Cleanup to:

• Remove temporary Internet files.
  
• Delete downloaded program files, such as Microsoft ActiveX controls and Java applets.
  
• Empty the Recycle Bin.
  
• Remove Windows temporary files, such as error reports.
  
• Delete optional Windows components that you don't use.
  
• Delete installed programs that you no longer use.
  
• Remove unused restore points and shadow copies from System Restore.
  
• Delete system files (Windows 8).

Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.
To use Disk Cleanup:

Windows 8 users

1. Open Disk Cleanup by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Disk Cleanup in the search box, tapping or clicking Settings, and then tapping or clicking Free up disk space by deleting unnecessary files.
   
2. In the Drives list, tap or click the drive that you want to clean up, and then tap or click OK.
   
3. In the Disk Cleanup dialog box, on the Disk Cleanup tab, select the check boxes for the file types that you want to delete, and then tap or click OK.
   
4. In the message that appears, tap or click Delete files.

More information and instruction is available to help you to delete system files in Windows 8.

Windows 7 users

1. Click Start, click All Programs, click Accessories, click System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
   
2. When Disk Cleanup has calculated how much space you can free up, in the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
   
   
3. Clear the check boxes for files that you don't want to delete, and then click OK.
   
   • For more options, such as cleaning up System Restore and Shadow copy files, under Description, click Clean up system files, and then click the More Options tab.
4. When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner, performing better, and potentially increasing your PC speed.

Windows Vista users

Watch the demo (1:00)

1. In the Start menu, click All Programs, click Accessories, click System Tools, and then click Disk Cleanup.
   
2. In the Disk Cleanup Options dialog box, choose whether you want to clean up your own files only or all of the files on the computer. If you are prompted for an administrator password or confirmation, type the password or provide the confirmation.
   
3. If the Disk Cleanup: Drive Selection dialog box appears, select the hard disk drive that you want to clean up, and then click OK.
   
4. Click the Disk Cleanup tab, and then select the check boxes for the files you want to delete.
   
5. When you finish selecting the files you want to delete, click OK, and then, to confirm the operation, click Delete files. Disk Cleanup then removes all unnecessary files from your computer. This may take a few minutes.

The More Options tab is available when you choose to clean files from all users on the computer.

Windows XP users

1. Click Start, and then click My Computer. Right-click Local Disk, and then click Properties. On the General tab, click the Disk Cleanup button. If several drives are available, you might be prompted to specify which drive you want to clean. Disk Cleanup will spend a few minutes examining your disk.
   
   
2. In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
   
   
3. Clear the check boxes for files that you don't want to delete, and then click OK.
   
4. When prompted to confirm that you want to delete the specified files, click Yes.

After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and potentially performing better.

3. Speed up access to data

Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk as a file is opened (to piece it back together). The response time can be significantly longer.
Optimize Drives (Windows 8) and Disk Defragmenter (sometimes shortened to Defrag by users) are Windows utilities that consolidate fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end to end, without fragmentation, reading and writing to the disk speeds up.
When to run Optimize Drives or Disk Defragmenter
In addition to running these utilities at regular intervals (weekly is optimal), there are other times you should run it, too, such as when:

• You add a large number of files.
  
• Your free disk space totals 15 percent or less.
  
• You install new programs or a new version of the Windows operating system.

To use Optimize Drives:

1. Open Optimize Drives by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Defragment in the search box, tapping or clicking Settings, and then tapping or clicking Defragment and optimize your drives.
   
2. Under Status, tap or click the drive you want to optimize. (The Media type column tells you what type of drive you're optimizing.)
   
3. To determine if the drive needs to be optimized, tap or click Analyze. You might be asked for an admin password or to confirm your choice.
   After Windows is finished analyzing the drive, check the Current status column to see whether you need to optimize the drive. If the drive is more than 10% fragmented, you should optimize the drive now.
   
4. Tap or click Optimize. You might be asked for an admin password or to confirm your choice.
   Optimizing a drive might take anywhere from several minutes to a few hours to finish, depending on the size of the drive and degree of optimization needed. You can still use your PC during the optimization process.

Notes

• If the drive is being used by another program, or is formatted using a file system other than NTFS, FAT, or FAT32, it can't be optimized.
  
• Network drives can't be optimized.
  
• If a drive isn't appearing in Optimize Drives, it might be because it contains an error. Try to repair the drive first, then return to Optimize Drives to try again.

Additional information and instruction to optimize your hard drive for Windows 8 is available.
To use Disk Defragmenter:

Windows 7 users

1. Click Start, click All Programs, click Accessories, click System Tools, and then click Disk Defragmenter.
   
   
2. In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze disk button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.
   
   Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
   
3. To defragment the selected drive or drives, click the Defragment disk button. In the Current status area, under the Progress column, you can monitor the process as it happens. After the defragmentation is complete, Disk Defragmenter displays the results.
   
4. To display detailed information about the defragmented disk or partition, click View Report.
   
5. To close the View Report dialog box, click Close.
   
6. You can also schedule the Disk Defragmenter to run automatically. (Your computer might even be set up this way by default.) Under Schedule, it reads Scheduled defragmentation is turned on and then displays the time of day and frequency of defragmentation. If you want to turn off automatic defragmentation or to change the time or frequency, click Configure schedule (or Turn on Schedule, if it is not currently configured to run automatically). Change the settings, and then click OK.
   
7. To close the Disk Defragmenter utility, on the title bar of the window, click the Close button.

Windows Vista users

In this version of Windows, Disk Defragmenter is set to run every week, so you don't have to remember to run it and you don't need to do anything else. However, you can change how often Disk Defragmenter runs, and at what time of day. To change the schedule:

1. Click Modify schedule....
   
2. In the Disk Defragmenter: Modify Schedule dialog box, choose how often, which day, and at what time of day you want defragmentation to occur, and then click OK.
   
3. Click OK again.

To manually open Disk Defragmenter:

1. Open Disk Defragmenter by clicking the Start button, clicking All Programs, clicking Accessories, clicking System Tools, and then clicking Disk Defragmenter. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
   
2. Click Defragment Now.

Disk Defragmenter may take from several minutes to a few hours to finish, depending on the size and degree of fragmentation of your hard disk. You can still use your computer during the defragmentation process.

Windows XP users

1. Click Start, and then click My Computer.
   
2. Right-click on Local Disk, and then click Properties.
   
3. Click the Tools tab, and then click Defragment Now. The Disk Defragmenter dialog box appears.
   
   
4. Click the drives that you want to defragment and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.
   
   Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
   
5. To defragment the selected drive or drives, click the Defragment button. Disk Defragmenter will work for at least several minutes, although it might take several hours. When prompted, click Close.

4. Detect and repair disk errors

In addition to running Optimize Drives, Disk Cleanup, and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.
As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult or even impossible. The Error Checking utility scans the hard drive for bad sectors and scans for file system errors to see whether certain files or folders are misplaced.
If you use your computer daily, you should run this utility once a week to help prevent data loss.

Run the Error Checking utility:

Windows 8 users

1. Open Computer by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Computer in the search box, tapping or clicking Apps, and then tapping or clicking Computer.
   
2. Press and hold or right-click the drive you want to repair, and then tap or click Properties.
   
3. Tap or click the Tools tab, and then, under Error checking, tap or click Check. You might be asked for an admin password or to confirm your choice.
   
4. Follow the instructions. You might need to restart your PC after error checking is complete.

Windows 7, Windows Vista, and Windows XP users

1. Close all open files.
   
2. Click Start, and then click Computer.
   
3. In the Computer window (My Computer in Windows XP), right-click the hard disk you want to search for bad sectors, and then click Properties.
   
4. In the Properties dialog box, click the Tools tab.
   
5. Click the Check Now button.
   
6. In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
   
   
7. If bad sectors are found, choose to fix them.

Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.

5. Learn about ReadyBoost

If you're using Windows 8, Windows 7, or Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory. With Windows 8, if you have a storage device that will work with ReadyBoost, you’ll see an option to use ReadyBoost when you plug the device in to your PC.
