If it detects registry damage, it tries to fix it automatically. Windows Setup runs the Windows Registry Checker tool to verify the integrity of the existing registry before it performs an upgrade. If the registry contains more than 500 KB of empty data blocks, Windows Registry Checker automatically optimizes it. This is equivalent to running the scanreg /fix command from a command prompt.
If no backups are available, Windows Registry Checker tries to make repairs to the registry.
This is equivalent to running the scanreg /autorun command from a command prompt. If invalid registry entries are detected, Windows Registry Checker automatically restores a previous day's backup. Windows Registry Checker automatically scans the system registry for invalid entries and empty data blocks when it is started. This article describes the Windows Registry Checker tool. Files that Windows Registry Checker backs up include System.dat, User.dat, System.ini, and Win.ini. It just keeps working.When you start your computer successfully, the Windows Registry Checker tool (Scanreg.exe) creates a backup of system files and registry configuration information (including user account information, protocol bindings, software program settings, and user preferences) once daily. I'm writing this because I'm installing it on a notebook that, after paying top dollar for registry software that has significant issues, I'm visiting the site to download Old Faithful - Free Windows Registry Repair 2.5. Once repaired, it must scan to put all the books on the shelf in order.Ĭons: Right or wrong, this is my logical conclusions after using the software for some 7 years. (Most people don't put a library book back where they found it!) The registry first finds all the errors of wrong books on the wrong shelves. Registry files are like a library shelf that get mixed up the more it is used. The software should be used (your registry scanned) multiple times until the number of problems are fixed completely or appear to be permanent. However, let me pro vide an answer to previous concerns. I've been using this product on all my machines since3 2005. This User will respond to concerns of other users.
