get the original speed back

As you use your computer - running processes, adding programs and creating documents - the wear and tear of normal use can really slow things down. If you are missing the speed and performance of your laptop, try these tips to speed it up and restore its potential. Most of these tips are really simple and you should notice immediate results. Windows operating systems include a number of these tools that make restoring your computer easy.
Remove Unwanted Startup Programs
One drawback to buying a fully loaded laptop or PC is that many free trial and sample programs are installed as bonuses with your operating system or other software. Sample programs are also acquired when we install new programs and tools. A lot of the time these programs run unseen in the background and most of the time they are set to run as soon as the computer boots up.
You can save your computer a lot of time - especially at start up - by removing these items from your start up list. Luckily, this is pretty easy to do: Click Start, then Run. In the Open search bar, type in msconfig and click OK. Now click the Startup tab and you will see a list of programs that are set to run automatically at start up. Click to remove the check from the box beside programs you can safely remove. Don’t remove any entries that you can’t recognize, as they might be important. Click Apply, then Close. When prompted to restart, click to restart. Check the box that says Don’t Show This Message or Launch System Configuration Utility, then OK.
Defragment your Hard Disk
Fragmentation on your hard drive is a normal result of use - as you add and remove programs and files, and the disk is crowded, rather than store programs in a block, bits of the program need to break up and spread out to find available space - vastly increasing the time it takes the computer to run the program. When files and programs are deleted, bits of data can remain behind, cluttering the hard drive and causing more fragmentation. Before you run the Defragger, it is important to go through your programs and files and delete everything you no longer want and empty the Recycle Bin. To run Windows Disk Defragmenter:
• Click to open My Computer
• Right click the drive you want to defrag - probably the C: hard drive
• Choose Properties
• Click the Tools tab, then choose Defragment Now
• Click Defragment
Allow the system to completely run the process, it might take a while to work through all the data - be patient and don’t interrupt the tool.
You can also run the Windows Disk Cleanup utility to get rid of unneeded data on your system:
• Click Start, All Programs
• Choose Accessories, then System Tools
• Click to run Disk Cleanup
These tips will keep your computer in prime working condition and help recover the speed and performance you enjoyed when your system was new.
