5 Best PC Cleaners For Optimizing Your Windows PC 2023

People often complain about their PCs’ slow performance and claim it reduces their productivity. Computers become slower for a number of reasons, including a lack of system resources, bloatware, out-of-date software, malware attacks, and more.

A few built-in PC optimization features in Windows 11/10 help users in managing the use of resources and free up unused disk space. However, it’s important to keep in mind that these programs only offer a minimal amount of cleaning and optimization. As a result, you might not be able to get your PC to run at its best. Instead, you can improve PCs using third-party programs.

These PC cleaning programs can carry out more thorough cleaning. They find more useless files, temporary files, duplicates, and other redundant data than the built-in Windows utilities.
