Portable Optimizer 16.5 Multilingual



A fresh Windows installation isn’t as clean as many users would like, as some of the features included in the latest versions of the OS are seen as unnecessary, hampering performance and compromising your privacy.

Optimizer Portable is a user-friendly program that lets you disable various Windows functions, delete superfluous files, remove objects from the starting list, manage the Registry, and more. It is open-source and entirely portable.

Disable Windows features that may be reducing performance and affecting your privacy

The application can disable telemetry, Windows Defender, network throttling, Skype advertisements, error reporting, and more, as well as conduct some general performance optimizations. Although the procedure is simple, it would have been beneficial if some explanations were supplied.

Depending on your Windows version, the program will also allow you to make various adjustments that are exclusive to that version of the Microsoft operating system. These can be found in the second tab, but no explanations are provided.

Clean unnecessary files, remove unwanted startup programs and fix registry issues

Optimizer can help you free up disk space by removing various files that may no longer be necessary, such as temporary items, logs and cache files.

Additionally, it is possible to inspect processes that have been added to the startup list and remove the ones that you prefer not to be launched automatically.

What’s more, you can use this program to fix a number of common registry issues, and it can restart File Explorer automatically in order to apply them.

Edit your hosts file and add new items to the context menu

Optimizer makes it easy to add new mappings in your hosts file or remove them, either by inserting individual items or processing the file in an advanced editor.

Lastly, this utility enables you to add custom commands to the right-click context menu, such as programs, shortcuts to folders, website links or files.

All in all, Optimizer is a very useful application that can help you optimize Windows in various ways, clean up your PC and even customize the right-click context menu. It could use some documentation, but it is easy enough to use and features an intuitive, minimalistic UI.
