Registry Editor — Windows 98 Simulator

The Registry replaced the old .ini files in Windows 95 and 98, and Regedit was the tool to open its hive. Tweaking a key by hand could change the look of the desktop or break the system, so every tip site of the time warned: "Always back up your registry first."

Registry Editor (regedit) from Windows 98 with the six root keys, string, binary and DWORD values, Find and Find Next, and Import / Export Registry File in the REGEDIT4 format.

The simulator’s own settings live under HKEY_CURRENT_USER, so changing a value really changes the desktop.
