How does the SR-2 Update work?
When you run the SR-1 Update, it modifies your current files to correct issues. This process helps keep the SR-1 Update small in size, but certain issues arose with the release of the WinAlign feature in Windows 98. NOTE: These issues have since been corrected. The SR-2 Update uses a different process to update your files. Instead of modifying them, the SR-2 Update backs up your current files and installs new files. After all of the new files are installed, the SR-2 Update deletes the original files. This process allows “rollback” (the ability to quickly and easily restore your system to its previous state), in the event that the SR-2 Update fails. The downloaded SR-2 Update is 23 MB in size; you must have approximately 60 MB of free space available on your hard disk when you run the SR-2 Update.
