Vit Registry Fix Free is one of the nicer freeware registry tools we've tried, and one of the more thorough in its actions, too. It creates automatic backups of your registry before it changes anything, so it's safe for beginners.
Vit removes a variety of unnecessary entries from your registry. That usually makes your system boot more quickly and run faster. Vit also packs in some useful extras, including a Registry Optimizer and Disk Cleaner.
Vit Registry Fix has a clean and attractive interface that is a welcome break from the overstyled GUIs so common these days. Before we started a scan, we visited the Settings tab, where we could uncheck any of the scan categories, configure shortcut scans, and uncheck the registry backup option. We strongly recommend leaving the backup option checked, though, unless you have a different registry backup active or you're certain the scan's findings are safe to remove. Vit also offers an Ignored List for keys the scan should skip.
Vit's other tabs give access to a History file, a Software list, and a Tools menu. When we'd made all our selections, we ran a scan. On its first scan, Vit turned up quite a few invalid entries, most of which were in the Deep Scan section and related to junk left over from uninstalled software. Clicking Show Results displayed a detailed listing of the scan's findings, each with its own check box. Vit's toolbar has "Select all" and "Deselect all" buttons, making it easy to select what to remove. Clicking Fix Error cleaned the list up. While we can't swear our PC ran more quickly, nothing bad happened, and at least we knew the garbage had been taken out.
The Registry Optimizer is a separate, bundled tool that compacts the registry. It requires a reboot. It reclaimed quite a bit of space from our registry, and our system booted normally and just a bit more quickly, too.
Some of Vit Registry Fix Free's English translations could use a bit of tweaking themselves. But we have no trouble recommending this free tool's registry tweaks.
