How to Speed up your Computer.

 How to Speed up your Computer ?

First time when we buy a new computer or reinstall our computer operating system, our computer was fast and finally after few months (or years maybe) our computer is slower than before. Sometimes we got annoyed  by our computer itself. To speed up your computer, I will give you some tips to speeding it up :

1. Remove unnecessary programs

No need long explanations, we all know more programs we've installed it will slow down your computer. You can uninstall it from control panel.

2. Remove unnecessary service

Too many running service can slow down your computer , even can make your computer not responding too. You can remove some unnecessary service by using task manager by pressing CTRL+SHIFT+ESC or right click on taskbar then click task manager. On task manager windows click details tab, then right click on process you want to close and click end task.

on older version of windows, open task manager, then click process tab, right click process you want to close, then end process.

3. Delete all files on prefetch folder and temp folder

What is prefetch folder ? 
The Prefetcher is a component of versions of Microsoft Windows starting with Windows XP..It is a component of the Memory Manager that speeds up the Windows boot process, and shortens the amount of time it takes to start up programs.

What is temporary folder ?
In computing, a temporary folder or temporary directory is a directory used to hold temporary files. Many operating systems and some software automatically delete the contents of this directory at bootup or at regular intervals.

Deleting files on prefect and temp folder can speed up your pc. Folder location for prefetch is C:\Windows\Prefetch,  for temp folder C:\Windows\Temp

4. Free up some disk space

Too many files, can slow down read-write process. You can get disk space by deleting unnecessary files or by using disk clean-up, first right click on drive you want to clean, then click disk cleanup. On disk cleanup Windows check all files you want to delete and click ok. For alternatives you can use utilities software like Ccleaner or Tune-up utilities, It's more effective than default disk-cleanup.

5. Repair your Registry

What is Registry ?
The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems. It contains settings for low-level operating system components and for applications running on the platform that have opted to use the registry. 

To repair registry you can find Registry fixer on the internet, there is so many registry fixer on the net,  for example use Ccleaner or Tune-up.

6. Adjust Visual Effects for Better Performance

Windows have some interesting visual effect that can make your desktop look beautiful, but too many visual effect can impact your windows performance. To adjust visual effect go to System (right click My Computer > Properties), then click Advanced System Settings. On System Properties Windows, click Advanced tab and click settings on performance. There you can check and unchecked unnecessary effect, and click ok.

7. Defrag your drive

Defrag your drive can give more performance, especially for read-write process. To defrag you can use default Windows disk defragmenter, or by use third-party software, there is so many software like that. 

8. Remove unnecessary start-up programs

If your pc boot-up slowly, you might check your start-up programs, maybe there is too many programs to start by your computer. to remove press Windows+R  then type "msconfig" without quotes. Click startup tab, then check or unchecked unnecessary start-up.

On Windows 8 there is a bit difference, to edit start-up items, just open task manager then click startup tab.

9. Scan your PC from virus, spyware, malware, and adware.

A computer virus is a computer program that can replicate itself and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability. Virus might be a small program but can harm your computer, Virus may cause a real big problem for your pc.

Spyware is software that aids in gathering information about a person or organization without their knowledge and that may send such information to another entity without the consumer's consent, or that asserts control over a computer without the consumer's knowledge

Malware, short for malicious (or malevolent) software, is software used or created by attackers to disrupt computer operation, gather sensitive information, or gain access to private computer systems.

Adware, or advertising-supported software, is any software package which automatically renders advertisements in order to generate revenue for its author. The advertisements may be in the user interface of the software or on a screen presented to the user during the installation process.

I will add some tips again later.

WindowsAndroid "Lets Android run on Windows"

WindowsAndroid

OFFICIAL WEB http://www.socketeq.com/

WindowsAndroid is Android running with Windows kernel!

It does not run by a simulator (such as VirtualBox), it's on real machine, so it's fast!

It keeps full Android capabilities. You can run all Android apps, including 3D games!

ScreenShot

More Info :

Even wonder what it would be like to play Android apps and games on your Windows laptop or desktop? Well Socketeq has got a solution. Socketeq, a Beijing based start-up company, has put together a system called WindowsAndroid that takes the Android OS and lets it run naively (unlike Bluestacks which only emulates Android) on the Windows kernel (Vista, Window 7 or Windows 8) instead of Linux.

Not only does this run Ice Cream Sandwich smoothly but it allows you to run it in the appropriate tablet or smartphone UI, and works fully with the mouse and keyboard as well. Those of you who have a new Windows 8 machine with a touchscreen will be able to take advantage of that feature and should make you feel right at home. However, remember this is not a full release so don't be surprised if you do encounter some glitches or bugs while your using it.

WindowsAndroid is still in development and there is no Google Play Store yet but you are able to side-load apps by placing the .APK files in the WindowsAndroid root\data\app directory and then restarting the program. Again, it is a work in progress so don't expect every app you try to load to work perfectly. After all some apps don't even work on actual Android devices that they were designed to work for.

All in all you will find things like a calculator and calendar features will work and you can even use Android's browser to surf the net and change wallpapers as well as run games and apps. Obviously for gaming a touchscreen Windows 8 machine is ideal but you can also play them using a mouse. If you want to play around with the early build you can head over to Socketeg site and click on download to try it out for free.
