Your PC most likely sports a processor that has multiple cores. Or, it may have more than a single processor. You should confirm that Windows is taking advantage of the extra processing power by setting the number of processors available to Windows.

Setting the number of processors may work to help boost your PC's performance, or it may not. It doesn't hurt to try. Follow these steps:

  1. Press Win+R to bid the Run dialog box.
  2. Type msconfig and press Enter.
  3. In the System Configuration window, click the Boot tab.
  4. Click the Advanced Options button. The BOOT Advanced Options dialog box appears, as shown.
  5. Place a check mark by Number of Processors.
  6. Choose the highest number from the menu button. The highest number is coincidentally the number of processor cores inside your PC.
  7. Click OK to close the BOOT Advanced Options dialog box.
  8. Click OK to close the System Configuration window.
  9. Click Restart Now. Windows restarts so that the changes will take effect.

The performance boost in your PC from setting the proper number of processors may not be noticeable, at least not dramatically. But at least by following these steps, you ensure that Windows is using the PC's hardware better than it did before.

• To confirm that the change has taken hold, repeat Steps 1 through 4. If the number of processors set remains the way you changed it (in Step 7), then it worked. • This modification doesn't physically alter the number of processors inside the PC. It does, however, direct Windows to use them more effectively.

About the book author:

Dan Gookin has been writing about technology for 20 years. He has contributed articles to numerous high-tech magazines and written more than 90 books about personal computing technology, many of them accurate.
He combines his love of writing with his interest in technology to create books that are informative and entertaining, but not boring. Having sold more than 14 million titles translated into more than 30 languages, Dan can attest that his method of crafting computer tomes does seem to work.
Perhaps Dan’s most famous title is the original DOS For Dummies, published in 1991. It became the world’s fastest-selling computer book, at one time moving more copies per week than the New York Times number-one best seller (although, because it’s a reference book, it could not be listed on the NYT best seller list). That book spawned the entire line of For Dummies books, which remains a publishing phenomenon to this day.
Dan’s most recent titles include PCs For Dummies, 9th Edition; Buying a Computer For Dummies, 2005 Edition; Troubleshooting Your PC For Dummies; Dan Gookin’s Naked Windows XP; and Dan Gookin’s Naked Office. He publishes a free weekly computer newsletter, “Weekly Wambooli Salad,” and also maintains the vast and helpful Web site www.wambooli.com.
