Microsoft has a long history of operating systems (OS); not all of them were as lean and good looking as Windows 7. As an OS, Windows 7 has shown remarkable longevity and adaptability. Still, with enough strenuous use, any OS will start to show signs of age and slips in performance. Once these dips in performance occur, you have two options: Improving performance or doing a clean install of Windows.

Improving Performance

Sometimes people pull the plug on their operating system way before they need to. Sometimes, rather than reformatting your hard drive completely, wiping all your data and installed programs and starting the OS again from scratch, it would be much easier to start running a few performance boosts:

Now, I don’t recommend running all of these every time you feel your system seems like it could be running faster. I tend to prefer running clean installs over tedious OS maintenance and troubleshooting, but as a rule of thumb, if you do four of the above tasks and still don’t notice a difference in performance, I would do a clean install.

How to Clean Install

For clarities sake, a clean install is when you install a new OS on an empty hard drive or a newly formatted hard drive. Remember that formatting your hard drive permanently erases everything on the partition, so back up everything you intend to keep on a second hard drive or external.

Remember also that all applications you installed on your previous OS will be lost, so keep those installation discs around so you can reinstall them on the new OS. To do a clean install, do the following:

  1. Insert the Windows 7 installation disc and restart your computer.
  2. Press F12 in the BIOS menu, and select the boot from disc drive option.
  3. Follow the instructions that appear.
  4. On the “Which type of installation do you want?” page, click “Custom.”
  5. On the “Where do you want to install Windows?” page, click “Drive options (advanced).”
  6. Click the partition that you want to change, click the formatting option you want to perform (reformat partition), and then follow the instructions.
  7. After formatting, complete the rest of the instructions. Your computer will restart a couple times, and then Windows 7 will startup.

    Windows 7 is such nicer OS to work with. I find it easier to increase performance and I always go for it instead of Clean Install, unless it’s crowded with viruses.

    I also use Clean install when a new upgrade like video card does not work after multiple tries of installing the drivers.

    Clean install is good for removing virus, malware, spyware, registry errors, replace currupt windows files, or if you can’t update windows to the latest service pack or patch.

    Clean install is certainly a good idea to blow the cobwebs from any version of Windows – arguably doing it once a year would be a wise move if you can spare the time to reinstall everything.

    In addition to backing up documents it is worth backing up drivers (assuming you have kept them up to date) to reinstall them more easily as you may find it difficult to find them afterwards (especially if you can’t access the internet because of missing LAN/WLAN drivers!) The free Double Driver software is a good tool for this.

    W7 is better than Vista/XP at supplying its own drivers but can’t include them all – and the generic MS driver may not work as well as the proper manufacturers driver anyway.

    Nice info and tips here. In where I’m staying, a clean install by a repair shop would cost around $50.

    I personally like Re-imaging a hard drive with pre-installed software with a fresh version of Windows then doing a clean install since I found clean installs to be time consuming.

    I think that if computer shops install all the users necessary software like MS-Word, Google Chrome, etc, and image the computer with CloneZilla or the built-in Image program in Windows 7, it would save time in the long run. A system image is like a system restore from a USB or Network Hard drive.
