After updating, System Checkup is detecting many more registry errors than before. Is this normal?
Yes, some product updates will include enhancements to tools such as System Checkup's registry optimizer. It is normal for a newly enhanced tool to detect a large amount of errors the first time it is run. Though it may seem like these errors have appeared out of nowhere, they have actually existed on your PC the whole time. Now that System Checkup is able to detect these previously undetectable errors it will also be able to correct them and improve your system's performance even further.
