PC Optimization Free

In the year 2021, the best free PC cleaner will be available.

For those times when your computer is starting to feel slow but not enough to necessitate a hardware update, free PC optimizers can provide a modest but noticeable performance increase.

There are a lot of free PC cleaners and optimizers out there that claim to make your computer run quicker, but not all of them live up to the hype. That’s why we’ve put all of the most popular alternatives to the test and compiled a list of the ones we think would give your PC a considerable speed boost while avoiding any frills or obtrusive adverts.

Iolo System Mechanic is the greatest free PC optimizer available today. It’s a feature-rich toolbox with everything you need to delete superfluous files, fine-tune your PC’s settings, and secure your privacy all at once. If your requirements are easier, we’ve compiled a list of four other fantastic applications that will thoroughly clean your PC without overwhelming you with options.

It’s worth noting that you can do a lot of what these free PC optimizers do yourself with Windows’ built-in system maintenance tools, but doing so takes time; what’s being sold here is convenience.

Many of these free PC optimizers also have premium counterparts that can handle more complicated tasks and give additional options like secure file deletion and scheduled scans if you want more capabilities.

Iolo System Mechanic cleans out junk files and unnecessary apps, prevents bloatware and undesirable auto-run settings, frees up RAM, and deletes logs, browser histories, and caches.

This not only frees up important system resources but also removes traces of your surfing activities, protecting your privacy.

Its PC optimization toolbox truly makes a difference; every time we’ve tested System Mechanic, we’ve noticed a big speed boost, particularly at startup. The free version is good, but the two premium editions – System Mechanic and System Mechanic Pro – are well worth considering if you use it frequently – and Iolo is currently providing a 70% discount with the code TECHRADAR.

We chose System Mechanic as our preferred PC optimizer because of the genuine performance gain we experienced after running it. Continue reading to learn about four more of the greatest programs for speeding up your Windows PC.

2. Restore

Restore doesn’t have the most extensive feature set we’ve seen, but it does an excellent job of giving the necessities and managing them effectively without adding too many frills.

With the powerful system repair tool, a variety of problems are looked for, identified if discovered and rectified. Malware detection is included in all Restore scans. Any suspect files will be discovered instantly, and you will be able to determine whether or not they should be removed.

You will benefit from the power of Restoro’s exceptional real-time monitoring features if you have one of the two unlimited use options. These are intended to assist you in keeping an eye on your computer, detecting potentially dangerous apps or security breaches before any harm is done.

Restore’s full money-back guarantee should be self-explanatory, but it implies that if you’re unhappy with the program’s performance, you may seek a full refund.

The only drawback is that the free version just allows you to use the software, not the repair tools.

3. Free IObit Advanced SystemCare

Reasons to purchase

+Clean, configurable interface+Auto cleanup and one-click operation

Reasons to stay away

-Cannot exclude particular files-Installer contains other software

The free edition of IObit Advanced SystemCare covers basic housekeeping, while the Pro version adds internet speed-boosting, real-time optimization, privacy protection, deep registry cleaning, and 24/7 technical assistance. For a year, the license costs US$20 (about £15, AU$25), and it covers three PCs.

IObit Advanced SystemCare’s UI is nicely designed, straightforward to use, and unlikely to intimidate even the most inexperienced PC user, regardless of the edition you choose. We’d deduct points for an installer that wants to install other apps – that’s not in line with the principle of keeping unwanted software off your computer – but they’re easy to prevent if you opt for a bespoke installation.

It cleans up files and folders you don’t need, cleans up the Windows registry, and fixes issues on your hard drive, all from a simple, elegant dashboard, just like the rest of the PC optimizers below.

CCleaner by Piriform

+Reduces disk space usage+

Simple to use+

For both desktop and mobile devices

Reasons to stay away

-Many Windows tools are duplicated.

Piriform CCleaner has been around for a while, and one of the reasons for its continued popularity is that it cleans portions of your computer that many other free system optimization applications don’t.

The optimization program has a commercial version that adds real-time protection and cleanup scheduling, but the free edition of CCleaner covers the essentials like removing temporary files, clearing browser caches, deleting unneeded cookies while retaining the useful ones, and so on.

This is the free PC optimizer to attempt first if your PC is simply sluggish. It doesn’t have all of the technical functions of applications like System Mechanic, but what it does clean is notorious for slowing down computers.
