Shit! This junk is too slow

I know, I have been there too. I click on an application and it takes freaking forever to start. The first doubt that comes to most minds it "This junk is too slow". It may be or may be not. Try opening another application. If that too is slow, then may be you're right.

Now, what to do. Most people, just format their windows, plain and simple. There are a number of things you can do:

• First check that the system that you have meets the requirements of the operating system installed. Complex thing simple, install the right OS on the right hardware. If not, then either downgrade or upgrade the OS. (Sorry, lads cannot list system requirements of every windows available now, can I.)
• Download the Piriform CCleaner. Then, run it.
  
  You should get a screen like the above. First click Analyze and then after it's completion, click Run Cleaner . Now click, the Registry tab on the left. You should see something like
  
  Same as before, click Scan for Issues and the choose which issues to fix and then click Fix selected issues. When you click on that, a window will pop up asking you to make a backup of the registry. Choose Yes for that and fix the issues.
• Check if you have installed any McAfee or Norton software, then please uninstall them. They usually are resource hogs and take up a lot of resources.
• Update the antivirus and scan the junk.
• Lastly, run Disk Defragmenter and scan the entire system. After that, restart your system a couple of times.

This should solve most problems. If, I have not mentioned your favorite trick, then please comment.
