When you uninstall a program, its registry keys should be removed too, but this doesn’t always happen.
Deleting old registry keys won’t free up hard disk space (the amount of space used by each database entry is minuscule), or have much impact on memory usage when the registry is loaded at startup.
You’ll also be asked if you want to set Yahoo as your homepage; if you’d rather not, uncheck the box and click ‘Decline’ – this won’t stop Auslogics Registry Cleaner installing.
Finally, you’ll be asked if you want to install Auslogics Driver Update – again, uncheck the box if you’d rather not.
The registry cleaner itself is refreshingly simple; you can use a series of checkboxes to choose which types of registry entry to scan for, which is excellent if you’re just having issues with a previously installed program.
The registry is backed up by default before you make any changes, and can be restored using the ‘Rescue Center option at the top right.
