Over the years a PC might become slower and less reliable than it once was. This can be due to invalid registry entries, lots of background apps, malware, a fragmented and full hard disk and more besides. Although Windows already includes numerous system-maintenance tools to keep things ‘ticking smoothly,’ there are loads of PC optimization programs that can boost system performance at least a little with their hard disk and registry cleaners, disk defrag, RAM optimizers and startup tools.

The best PC optimization software includes a wide variety of system-maintenance tools and options, and these are a few freeware programs you can supercharge Windows with.

Iolo System Mechanic Professional (recommended)

System Mechanic is one of the most highly rated PC optimization programs for Windows. This has a freeware and Pro version that includes some more advanced modules with anti-virus, internet connection tweaker, Windows customization and search and recovery tools.

Nevertheless, the freeware version still has the essential maintenance tools to give Windows a genuine boost. Press the Start Download button on this web page to save System Mechanic’s installer to your hard disk.

System Mechanic has an intuitive and appealing UI design that includes most of the software’s tools and options within a left sidebar. It gives you a system status overview (shown in the snapshot above) that highlights things that need fixings, such as registry issues, junk files or fragmented hard drive. System Mechanic Free retains several of the essential tools from the full package. It has a junk file cleanup tool that does a system-wide scan to erase obsolete files.

It includes a registry tuner with which you can fix invalid registry entries, and that also comes with backup and restore options. With the software’s startup manager users can remove startup bottlenecks to speed up boot times. In addition, you can also speed up Windows with System Mechanic’s RAM optimizer that defrags RAM.

On top of that, this utility has tools to fix invalid shortcuts, repair internet connections and defrag hard disks; and users can run multiple tools at once with its wizards.

Iolo System Mechanic is one of the 7 software products included in the comprehensive security, privacy and optimization package Phoenix 360. If you are interested, you should definitely take advantage of its current discount from $79.95 to $39.95.

CCleaner (recommended)

CCleaner is award-winning PC optimization software with an extensive user base eclipsing two billion downloads. It has fairly thorough cleanup tools that don’t erase any more essential system files, and you can use this software to free up hundreds of megabytes of disk space, remove software, manage startup items and repair possible errors.

The freeware version of CCleaner might lack some of the scheduling, file recovery, and disk defragmentation tools included the Professional Plus package; but it still has a few handy options for system optimization.

You can add the freeware CCleaner to Windows, which is quite limited in actions and in customizing CCleaner’s work. But if you are interested in CCleaner-s full version – you can buy it here.

CCleaner’s primary tools are its hard disk and registry cleaners. It has flexible hard disk and registry cleaners that you can configure to delete a variety of more specific file and registry items.

The software also has extra settings that enable users to select specific folders or files to either delete or exclude from system scans. Another advantage of CCleaner’s hard disk cleaner is that it also enables you to clean up third-party software file items.

Beyond the HDD and registry cleaners, CCleaner’s tools might seem a little limited compared to some alternative optimization software. The freeware version doesn’t include any disk defrag, RAM optimizer, shortcut fixer, one-click maintenance option or much in the way of file management tools. However, it still has a good startup manager with which you can not only remove startup items, but also delete scheduled tasks and third-party software context menu entries.

CCleaner’s handy Browser Plugins tool enables users to quickly activate or deactivate browser extensions, apps and plug-ins. You can can also search for and erase duplicate files with the Duplicate Finder tool. So even if CCleaner doesn’t have the most extensive number of utilities, it’s still a handy Windows optimization program. Check out this Windows Report article for the full lowdown on CCleaner.

Ashampoo WinOptimizer

Ashampoo WinOptimizer is a stripped-down version of WinOptimizer 14. WinOptimizer 14 might have more extensive file management and system maintenance tools, but there are still plenty of options and settings to explore in the freeware version. You can add WinOptimizer trial version for Windows platforms from XP up by clicking here.

WinOptimizer Free has Drive Cleaner, Registry Optimizer and Internet Cleaner tools for system maintenance. Its One-Click-Optimizer provides a handy shortcut to run those tools simultaneously. The Drive Cleaner is flexible as users can create exclusion lists, add file filters and configure it to delete items to the Recycle Bin.

WinOptimizer’s Startup-Tuner is another more essential system maintenance tool with which you can disable Windows services and edit startup items. The program comes with a Task Scheduler for you to schedule optimization runs, and it also saves the most frequently used modules in Favorites for quicker access.

However, WinOptimizer isn’t just system maintenance software. It also includes handy Windows customization and file management tools. For example, the software has a Context Manager you can customize Windows context menus with. The Icon Saver enables users to save Windows desktop icon arrangements. In addition, you can split up, encrypt and recover files with WinOptimizer’s File Splitter, File Encrypter and Undeleter tools. So WinOptimizer offers more tools than most optimization suites.

Glary Utilities

Glary Utilities is a cut-down version of the Pro package. However, there isn’t that much difference between the freeware and Pro version aside from Glary Utilities Pro’s automatic updates, free technical support, and extra scheduling options. There’s also a free portable version of the software you can run from external drives.

Glary Utilities is packed with more than 20 system tools to optimize Windows with. It includes all the more standard tools such as disk cleaner, registry cleaner, startup manager, uninstalls manager and disk defrag. On top of that, this program also has less standard tools for removing malware, fixing invalid shortcuts, deleting empty folders, erasing duplicate files, splitting and joining files and even file recovery.

Glary Utilities enables users to run a custom 1-click Maintenance scan that incorporates a number of its tools, which can come in handy.

The program’s RAM optimizer enables you to select a more specific amount of RAM to free up with a slider bar. Glary Utilities also integrates with File Explorer so that you can select some of Glary’s file management options directly from context menus. Overall, Glary Utilities has almost all the tools you’ll need for PC optimization.

WinUtilities Free

WinUtilities Free is another all-in-one PC optimizer with a freeware and Pro edition, which has a $29.95 one-year subscription. The publisher reveals relatively little about the differences between the freeware and Pro editions of WinUtilities. The UI design of both editions is almost identical, but the File Undelete, Task Scheduler and Duplicate Files Finder only work in the Pro version, which also has free technical support.

WinUtilities Pro also boasts a more effective registry scan engine and disk cleaner. Open this page and press the Download Now button there to save the WinUtilities Free installer to Windows.

WinUtilities Free has an impressive 25 modules that consist of PC optimization, clean up and repair, files & folders, registry and other system tools. In the optimization category, users can select Registry Defrag, Disk Defrag, Startup Cleaner, RAM optimizer and BHO (Browser Helper Objects) Remover tools. The software includes a Disk Cleaner to remove junk data, Registry Cleaner to fix invalid registry entries, Shortcut Fixer and Uninstall Manager.

The software’s 1-Click Maintenance option incorporates most of the clean up and defrag tools. WinUtilities Free has some useful file and folder and registry tools to split and merge files, analyze disk space, back up the registry and remove and restore context menu options and settings with. The publisher has also packed all those tools within a clean and intuitive UI.

So those are five great utility software you can optimize Windows with. They provide RAM optimizers, disk and registry cleaners, startup managers, shortcut fixers, uninstall managers, duplicate file finders and disk defrag tools; and some of them also include additional Windows customization and file options. The best thing is that they’re all freeware software!
