Best Free Pc Tools Software

With our pick of the best free PC optimization software, you can give your PC's performance a noticeable boost.

Free PC optimization software can't solve obsolescence – if your computer is struggling to meet the system requirements for your OS or apps that's a job for more RAM or the addition of an SSD – but if the slowdown is software-related, it can really help.

The Best Free System Software for PC. We are looking for people with skills or interest in the following areas: - Mobile Platform App Reviews for Android and iOS - Windows, Mac and Linux software reviews. H ere is the list of top best ethical hacking tools 2019 for Windows PC, Linux system and MAC OS. These are the must have tools for every hacker required for different purposes. All these hacking tools 2019 provided here are effective and free of cost. List of top & best free software downloads, open source software, freeware, free utilities & tools for Windows 10/8/7 computer. Available as free download.

It's worth noting that you can do much of what these free PC optimization apps do yourself using Windows' built-in system maintenance tools, but that's time consuming; what's really being sold here is convenience.

If you want more features, many of these free PC optimization tools also have premium counterparts that can perform more advanced tasks, and offer additional tools like secure file deletion and scheduled scans.

1. Iolo System Mechanic

Enjoy a faster, cleaner PC with the best PC optimization tool

Clear, detailed analysis

Iolo System Mechanic removes junk files and unwanted apps, blocks bloatware and unwanted auto-run settings, clears out RAM and wipes various logs, browser histories and caches.

Not only does this free up key system resources, it also eliminates traces of your browsing activity to protect your privacy.

Its PC optimization toolkit really does make a difference; whenever we've tested System Mechanic we've found a significant speed improvement, especially at startup. The free edition is excellent, but the two premium versions – System Mechanic and System Mechanic Pro – are well worth considering if you find yourself using it regularly – and Iolo is offering a 70% discount with the voucher code TECHRADAR.

The genuine performance boost we saw after running System Mechanic made it our favorite system optimization tool. Read on for four more of the best apps around for speeding up your Windows PC.

2. IObit Advanced SystemCare Free

A hands-off approach to optimization that's ideal for novice users

One-click and auto cleanup

IObit Advanced SystemCare comes in two forms: a free edition version that covers basic house cleaning, and a Pro version that adds internet speed-boosting, real-time optimization, privacy protection, deep registry cleaning and 24/7 technical support. That's US$20 (about £15, AU$25) for a year, and the license covers three PCs.

Whichever edition you choose, IObit Advanced SystemCare's interface is well designed, easy to use and unlikely to frighten even the newest PC user. We'd deduct points for an installer that wants to add additional programs - that's hardly in keeping with the philosophy of keeping unwanted stuff off your computer - but they're easy to avoid if you choose a custom installation.

Like most of the free PC optimization software here, it cleans up files and folders you don't need, neatens up the Windows registry and corrects errors on your hard drive – all via a simple, slick dashboard.

3. Piriform CCleaner

Eliminate unnecessary files, clean the registry and manage apps

Frees up disk space
Duplicates many Windows tools

Piriform CCleaner has been around for a long time, and part of the reason for its ongoing popularity is that it cleans the parts of your PC that many other free system optimization tools don't.

There's a paid-for version of the optimization toolkit that adds real time protection and cleanup scheduling, but the free edition of CCleaner covers the important stuff such as removing temporary files, getting rid of browser caches, removing unwanted cookies while keeping the useful ones and so on.

If your PC just feels sluggish then this is the free PC optimization software to try first. It doesn't have all the advanced features of apps like System Mechanic, but the stuff it does clear is famous for slowing down PCs.

4. Ashampoo WinOptimizer 2019

A fast scanner plus a suite of well designed maintenance tools

Descriptive interface

Ashampoo WinOptimizer 2019's biggest selling point is its flexibility – you can scan for junk files, broken registry entries and browser cookies with a single click, and erase them all with one more.

Alternatively, you can dive deeper by selecting the 'Details' button to review the results of your scan one by one. Unlike some PC optimization tools, Ashampoo WinOptimizer gives you a full description of each issue it's identified, explaining exactly what it is, and why you should consider removing it. You can then make an informed decision about whether to erase or keep it.

WinOptimizer also includes a suite of 'modules' for routine maintenance tasks like defragging hard drives and optimizing startup processes. These are all tasks that could be accomplished within Windows itself, but having them all in one location is much more convenient than trawling through menus.

(In case you're wondering, Ashampoo takes its name from this optimization software, which cleans your PC 'like a shampoo'.)

5. Razer Cortex

Made to help gamers wring extra performance from their PCs

Frees up RAM for games
Contains some unnecessary extras

If your system struggles when you're trying to get your game on, Razer Cortex could well be the answer. This free PC optimization software suspends unnecessary system processes, clears out memory and defrags your system to get the very best game performance possible.

Razer Cortex is available for Windows 7, 8 and 10, and while the differences won't make you jump up and down in astonishment - for most people the results will mean slightly smoother visuals rather than astonishing performance improvements - it does automate the fiddly process of turning off unnecessary software and services when it's time to play.

Using free video editing software is a convenient way to edit your videos. Plus, most of them are so easy to use that they're great for beginning editors.

You might want a video editing program if you need to extract audio from a video or add different audio, cut out parts of the video, add subtitles, build a DVD menu, merge video files, or fade a video in or out. Most vloggers need a video editor of some kind.

Because most free video editors limit their features to advertise their professional versions, you may find roadblocks that stop you from making advanced edits. For editors with more-advanced features but that aren't free, check out mid-level digital video software or top professional video editing programs.

If you need to convert your video files to different file formats such as MP4, MKV, and MOV, this list of free video converters has some great options.

The fact that you get all of this for free is reason enough to download it yourself and try it out before you purchase a video editor.

  • Includes optional screen recorder.

What We Don't Like

  • Not super user-friendly.

  • Some video lag with free version.

VSDC is a full-featured free video editing tool that you can install on Windows. A fair warning though: This program might be a little hard to use for beginners because of the sheer number of features and menus.

However, if you poke around for while and play with your videos within the editor, you'll find that it's not quite as daunting as it seemed when you first opened it.

There's even a wizard you can run to make things easier. Use it to do add lines, text, and shapes, as well as charts, animations, images, audio, and subtitles. Plus, as any good video editor should, VSDC can export videos to a variety of file formats.

The VSDC Video Editor setup lets you easily install the company's video capture program and screen recorder. These are optional, but they may come in handy in certain projects.

What We Like

Best Free Software Tools For Pc

It's included in this list because it's already on lots of Windows computers, which means you might not even need to download anything in order to start using it.

Online-Only Options

If you've tried out these video editing programs but prefer some other options or you're more interested in editing videos online for free than downloading software, there are several online editors that function in the same way as these downloadable tools:
