The best system utilities and repair software makes it simple and easy to help your business computers run more smoothly and faster.

The best system utilities and repair software

As soon as you take your shiny new business PC out of the box and switch the machine on, it starts saving temporary files, caching pages, rewriting registry entries and otherwise populating the hard disk. Over time all of this stuff has an impact on the system as the disk becomes fragmented, old registry keys get left behind, items are added to startup and more.

It’s no surprise therefore that after a few months, your once fast PC can start to feel a bit more sluggish. Help is at hand, however, as there are a number of tuning tools available that can clean things up and help you get back that nippy, out-of-the-box feel.

If you want to tidy up your system or target a specific area such as your hard drive, we’ve put together this guide which highlights some of the best tuning software tools for the job. Note that all of these will run on Windows 10 and earlier versions of Microsoft's OS.

Here then are the best system utilities and repair software products for business computers.

1. CCleaner Business Edition

Versatile and easy-to-use clean-up tool

Reasons to buy
+Works with popular browsers and programs+Option for automatic monitoring
Reasons to avoid
-Interface feels dated

This is the business version of the popular free consumer CCleaner clean-up tool. On first use it scans your machine for cookies, history and temporary files related to popular browsers, as well as files from other popular applications. It also includes a registry cleaner and a range of other tools such as an uninstaller, a startup manager, a browser plug-in manager and a duplicate finder. There’s a drive wiper for cleaning up old systems before disposal too.

The software also gives you an option to monitor the system in the background and run a clean automatically when a previously specified amount of space can be saved.

Note that there are discounts available when it comes to purchasing larger numbers of licences. For bigger businesses there are network and cloud versions available that allow remote management of multiple endpoints. If you want a clean-up tool that’s simple to use and covers all bases, this one is well worth a look.

2. Restoro

Streamline utilities and repair software

Reasons to buy
+Great essentials+Fast, efficient scans+Very competitive prices
Reasons to avoid
-Limited free version

Although Restoro certainly doesn’t boast the largest feature list we’ve seen, it does a great job of providing the essentials without adding too many unnecessary extras. 

Numerous problems are scanned for, listed if found, and repaired with the powerful system repair tool. All Restoro scans include built-in malware detection. Any suspicious files will be immediately identified, and you can decide whether or not they need to be removed.

If you have one of the two unlimited use plans, you will benefit from the power of Restoro’s excellent real-time monitoring tools. These are designed to help you keep tabs on your computer, identifying potentially dangerous apps or security breaches before any damage is caused. 

This should be quite self-explanatory, but Restoro’s full money-back guarantee basically means that you can request a full refund if you’re not happy with the program’s performance. 

The only negative is that the free version allows you to run the software, but not any of the repair tools.

3. AVG TuneUp

A good choice for non-technical users

Reasons to buy
+Smart and modern interface+Built-in performance advisor
Reasons to avoid
-Slow scanning

AVG TuneUp has been around for many years, but the current version has a smart, modern look. Run a scan - which takes a while to complete though it does display a graphic indication of progress - and you’re presented with an easily read dashboard display showing which areas need attention. Sadly, when you click on an item for more detail, the style of the application proves to be inconsistent.

As well as dealing with browser data it cleans up system logs and caches, looks for registry problems and broken shortcuts, helps manage startup and shutdown, and checks for disk fragmentation. There’s an automatic maintenance option and a performance advisor that offers tips for speeding up the system – by disabling background tasks, for example. The program can also produce a monthly optimisation report.

Again, bulk discounts are available when buying for multiple systems. With its useful tips and clear interface this is a good choice for non-technical users.

4. Ashampoo WinOptimizer

Fast and has lots of useful features

Reasons to buy
+Fast scanning+Privacy control for Windows 10
Reasons to avoid
-Need to drill down to uncover some info-Intrusive advertising

Ashampoo WinOptimizer is compatible with all versions of Windows from 7 onward. The freshly overhauled interface is clear and there’s a choice of styles when you install the program. Click the search button to begin the optimization process – once it’s complete you have the option to examine the details of what the program has found, or just run an automatic fix.

Ashampoo’s effort does the usual file and registry clean-ups, plus it provides additional tools including a backup manager so you can roll back changes should a cleaning process mess something up. It also includes a Privacy Control Module for Windows 10 which allows you to manage what data is shared with Microsoft; a pretty nifty touch.

There’s an auto-clean option, too, and a live tuner which optimizes performance by managing background tasks. Furthermore, there’s a new SSD Wizard for optimizing solid-state drives.

Discounts are available for multiple licenses, plus there’s a fully functional free trial to allow you to try the program for yourself. WinOptimizer scans quickly and provides a lot of data but you do need to drill down into the interface to find some of it. The program also constantly tries to sell you other products which is a bit irritating.

5. Iolo System Mechanic

Plenty of options for techies, but easy for ordinary users too

Reasons to buy
+Live performance optimiser+Ability to run tools independently
Reasons to avoid
-Dated interface-Limited control over some options

Iolo System Mechanic is one of the most popular tuning tools around and it's easy to see why. Although the interface isn't particularly special it does offer a comprehensive range of cleaning tools as well as the ability to optimize your CPU, memory and internet connection. It also allows you to manage startup programs. 

After a scan you can opt to repair all the issues it has found or dig deeper to view the details before deciding on whether to take action, though some areas offer more control than others. All of the tools can be run separately if you prefer. There's an ActiveCare option that will run cleaning tasks when the system is idle, and LiveBoost to improve system performance.

Note that there’s also a Pro version available with more features. If you want a tool that's easy enough for non-techies to handle but also lets you dig deeper if needed, then Iolo’s offering is for you.

6. SlimCleaner

Free to use and surprisingly comprehensive

Reasons to buy
+Crowd-sourced accuracy+Runs from a flash drive+Comprehensive
Reasons to avoid
-Some functions need a web connection

SlimCleaner from SlimWare is a tool that uses a community-based approach to recommend optimal settings for programs and services. It helps you to clean up the system as well as uninstall unwanted software. It can also identify the data clogging up your drive and securely wipe sensitive information.

There’s a defrag tool and a duplicate finder, optimization for solid-state drives, and it can check the versions of installed software to see if there’s a new version available. A hijack log also lets you identify potentially unwanted toolbars and BHOs. SlimCleaner can be run from a flash drive so you can use it to clean up several PCs without having to install the program on all of them. 

SlimCleaner is surprisingly comprehensive, and while there are some minor niggles, this is well worth considering for the performance boost mode and alerts for unwanted startup items.

7. Avast Ultimate

Internet security with system utilities

Reasons to buy
+Comprehensive bundle+Ransomware protection+VPN included
Reasons to avoid

Avast Ultimate is one of the most comprehensive internet security suites around. While it includes anti-virus software at its heart, it also provides additional features you'd struggle to find in similar bundles.

The package is really a combination of four of Avast's main products: Avast Antivirus Premier, Avast SecureLine VPN, Avast Cleanup, and Avast Passwords for Windows. This means you also get an automatic updater for your software, a file shredder to ensure data is properly deleted from your harddrive, as well as ransomware protection. There are privacy protections included, too, not least via the SecureLine VPN, and a password manager manager, too.

Avast Cleanup offers useful optimization utilities on top, though, such as help repair outstanding issues with the Windows registry, as well as delete junk files from temporary and cache folders, on top of general tuning for improved performance.

Altogether, Avast Ultimate isn't the cheapest security and privacy platform out there, but it's one of the most comprehensive, and the ability to better protect and control your critical data are definite selling points. 

The only real negative is that Avast keeps spinning off its services into separate products, means you can expect repeated pop-up ads on your screen telling you that you need to fix something - only to find that feature isn't included in your subscription, making you feel that perhaps you would have been better going with a competitor that does include everything.
