On the main screen there are the following grammar/phrasing errors:
Software Manager Tooltip:
"The Software Manager allows you to see what software are installed on your computer. You can uninstall software you no longer need or which you thought you had already uninstalled, even those not listed in the Windows Add/Remove software list."
Better:
"The Software Manager allows you to see what software is installed on your computer. You can uninstall software you no longer need or which you thought you had already uninstalled, even programs not listed in the Windows Add/Remove software list."
The tooltip for Startup Manager is missing a period at the end of the sentence, small detail, but still...
Edit: scratch the next one. I can see it was fixed in v.411.
On the Registry Finder tooltip, "this can save you a lot of time..." should be a separate sentence (another small detail, but still...).
Other than that, the tooltips look really good.
