Pros & Cons

    • Easy to use.
    • Effective system cleaning.
    • Community-based features.
    • Windows 10-specific data protection.
    • License limitations.
    • Can only uninstall unwanted apps one at a time.

The average tune-up utility improves your PC's overall system performance by repairing the problematic Windows registry, defragging the hard drive, and deleting junk files. However, SlimWare Utilities SlimCleaner Plus goes the extra mile by including community-based recommendations, the ability to recognize out-of-date antivirus software, and new Instant Alerts that let you know when suspicious software tries to latch onto your PC's startup process. Overall, SlimCleaner Plus is easy to use and has effective computer clean-up chops, but its license limitations prevent it from toppling the reigning paid tune-up king, Iolo System Mechanic 15.5.

System Requirements and Setup

Compatible with Windows 10/8/7/Vista/XP PCs, SlimCleaner Plus requires an Internet connection for downloading the software and any updates that may be required during installation. Unlike Iolo System Mechanic 15.5, our Editors' Choice for paid tune-up utilities, SlimCleaner Plus limits the number of installation licenses you receive for your money. You get one PC license for $29.97, three for $34.95, five for $56.95, 10 for $100.95, and 25 for $230. Iolo, on the other hand, lets you install its System Mechanic 15.5 software on as many PCs as you'd like—that's a sweet, potentially money-saving deal in the age of the multi-PC home. I wish SlimCleaner Plus, and other tune-up utilities, would adopt this model.

SlimCleaner Plus vs. SlimCleaner Free

If you're wondering about the differences between SlimCleaner Plus and SlimCleaner Free, here's the skinny: SlimCleaner Plus has a one-click scan and fix button, laptop power-consumption settings, the ability to deactivate unneeded features for greater computing efficiency, and Windows 10-specific protection that lets you customize the operating system's privacy settings to disable, or limit, features that collect and report data to Microsoft. For example, you can nix the "Getting to Know You" feature, which prevents Microsoft from gathering speech, contacts, and calendar information. If you're concerned about your digital footprint, this is a very useful feature.

SlimCleaner Free lacks those features, as well as SlimCleaner Plus' ability to identify inactive or out-of-date antivirus software, and the new Instant Alerts, which leverages community recommendations to notify you that unwanted software (such as a toolbar that came packaged with an application) tries to insert itself into the bootup process. In my tests, Instant Alerts triggered a pop-up window when it detected a browser toolbar (a toolbar that I didn't intentionally install, by the way). Instant Alerts gave me the option to either keep the toolbar or uninstall it, so I removed it. It's an incredibly useful feature.

About Our Expert

Jeffrey L. Wilson

Jeffrey L. Wilson

Managing Editor, Apps and Gaming

Since 2004, I've written about consumer tech for many publications, including 1UP, Laptop, Parenting, Sync, Wise Bread, and WWE. I now apply that knowledge and skill set as the managing editor of PCMag's apps and gaming team.

The Technology I Use

As a member of the App & Gaming team, I use a wide variety of apps and services. Google Drive is an essential file-syncing service for moving documents between team members in this work-from-home era. Scrivener has been an invaluable writing tool as I rework my fiction manuscript. YouTube Premium and YouTube TV deliver hours of entertainment (though I only use the latter service during the F1 and NBA playoff seasons).

In terms of hardware, I use a Lenovo Thinkpad Carbon X1 laptop for work and an Origin PC tower for playing PC games. I also have a Steam Deck, which lets me play my favorite titles under a shade tree. Of course, I have a smartphone, and the Google Pixel 9a is my handset of choice.

My main input devices are the Das Keyboard 4 Professional and Logitech MX Vertical Ergonomic Mouse, though I bust out the Hori Fighting Commander Octa or Hori Fight Stick Alpha when mixing it up in fighting games. I have a thing for arcade sticks. I collect Neo Geo AES games, too, but only if I can find the carts on the (relative) cheap.

For video and music consumption, I fire up my Lenovo Tab P11; it has a sharp screen and great Dolby Atmos-powered speakers. My Kindle Paperwhite has received much use, too. I have a standalone, Sony Blu-ray player connected to a TCL television when it's time to go full cinephile. I'm also a vinyl guy, so the Bluetooth-enabled Audio-Technica AT-LP60XBT keeps the wax spinning.

My first computer was a Commodore 64. Long live BASIC and retro computers!
