I have a Compaq laptop with Vista on it. It is about 4 years old, am I able to put Windows 7 on it? Since I can not afford at this time a new laptop I would like to get rid of Vista since I do not like it.
Shirley, I’ve got some great news for you. If your PC is running Vista then it most likely can run Windows 7. Microsoft has a free utility called the Windows 7 Upgrade Advisor which will scan your computer and report back on the upgrade ability and any possible conflicts.
Click here  to download Windows 7 Upgrade Advisor. Once you run Windows 7 Upgrade Advisor, a report will show on the screen giving you a list of possible compatibility issues t specific to your computer. You can review this report to determine if any software or hardware won’t work once you install Windows 7.
It’s also a good idea to visit your manufacturer’s website and look for drivers under the support section. You can find out if Windows 7 drivers are available for your computer’s internal devices. If there are drivers available, download them and put them onto a DVD or a USB flash drive. Once you complete the upgrade, you’ll have the drivers you need to install.
If you do decide to upgrade, I would look online or in-store for the Upgrade edition of Windows 7 Home Premium. This edition is the most popular version of Windows 7 and is designed for home users who do not need to connect to a corporate work network.
