Many PCs come with tools to optimize and clean the system, however it is possible to obtain more efficient results by downloading a third-party application. This article will help you choose the most effective freeware program for your PC.

Freeware is software that can be downloaded for free, but may have restrictions on its usage or distribution. Freeware is different from programs in the public domain, or that are not copyrighted, which means that they are free to be used for any purposes. Shareware programs are similar to freeware but the authors retain copyright on the program’s contents and may restrict other uses.

Freeware is usually released by vendors to give prospective customers a taste of their larger paid-for software. Freeware is also released by large, independent software vendors to promote their brand and reputation. Freeware could also include adsware that shows different kinds of advertisements to users using their computer. Another example is crippleware. The software blocks the user from accessing certain features until they pay a fee. Other forms of free software are donationware, which requests users to make an optional donation to the author or a third-party organization or a third-party organization, and nagware which reminds users to sign up to access a premium service. In contrast, GNU-compliant Freeware adheres to the principles of free software and isn’t bound by the terms of its license.
