Due to changes in Windows 11 and specifically with the recent version 24H2, Registry First Aid is no longer compatible and no further updates to the software are possible. However, Rose City Software has received some user reports that RFA seems to work OK with the new est Windows release, W 11 v 25H2 If you have the capability to test RFA under 25H2 we welcome your input. You should be able to use Windows Restore to restore your computer if you decide it is no longer functioning correctly after using RFA 11.3.1.

In any case Rose City Software has ceased to sell Registry First Aid as of Sept 1, 2025. Thank you to all our loyal customers over the past couple decades. You may continue to use the software as long as it functions properly with older versions of Windows 11 and Windows 10. If you misplace your registration information, we will maintain the database and still be able to retrieve it for you.
