Let's start with what programs load up when your computer is booting.
From the Start button, click it and choose Run. Type in msconfig and hit Enter or OK. There is a tab called Startup. When you click that, everything you see checked will load during bootup. Some things you need, some things you don't. What would those be? Depending on what you have installed, the list could be long and involved. A general rule of thumb is to let your knowledge of what you have be the guide. There's no need for Office, your printer and other unnecessary periperhals and programs. If in doubt, Google any Startup Item to see if it's a necessary process. To be doubly safe, uncheck the unknowns one at a time and reboot after each to see if the system is affected.
When you reboot the first time, you'll get a warning that says changes have been made to the startup. Check the box to not have the message shown again.
If the Command line is blank, this is a clue that it may not be safe. Many viruses and malware programs will hide themselves this way.
Next, let's take a look at your hard drive. Go to My Computer, click it and right click your hard drive. This should be your C dirve. Choose Properties. In the General tab, click Disk Cleanup. It will examine your drive to determine what can be done to clean out unnecessary files. I generally check every box except the Compress Old Files and let it do its thing by choosing OK.
Onwards to the next tab- Tools. Choose the Defragment Now box and then the drive (C) that you want to examine. Choose analyze and let it run. The more red you see, the more the files that need to be together are separated. The analysis will pop up a box and let you know the recommendation. This will take quite some time so allow for that. A word of warning- if you don't have 15% free space on your hard drive, it may not work at all. This is a great time to go to Control Panel> Add or Remove Programs and uninstall applications you no longer use.
Time to scan for malware, adware and viruses. Before you use your programs (you do have them, right?), make sure to update. I use a couple of different ones. AVG is my choice for anti-virus, I also use Spybot and Malwarebytes to check for malware,etc.
That's it. These all done in combination should help to speed things up.
