From a BIOS export to a ready-to-import file.
Export your BIOS settings to a .txt file with SCEWIN.
Open the file in NvramEditor. Search, change options or run Optimize.
Save only your changes and import the file with SCEWIN.
The app is free. For a complete configuration, we set up every SCEWIN option for you.
Short answers before you touch your BIOS.
NvramEditor only changes a text export on your PC. Nothing touches the BIOS until you import the file with SCEWIN yourself. Keep an untouched copy of your original export so you can always go back, and only change options you understand.
Run SCEWIN from an elevated Command Prompt, typically SCEWIN_64.exe /o /s nvram.txt to export and SCEWIN_64.exe /i /s nvram.txt to import. Switches can differ between SCEWIN versions, so check the readme that came with yours.
The saved file contains just the sections you modified, so importing it touches only those settings and leaves everything else as it is.
Yes, some options can. Clearing CMOS or using your board’s BIOS recovery usually brings it back, but that is not guaranteed on every board. Change a few settings at a time and keep your original export.
Send your own export on Discord and we set every SCEWIN option for you, then return a file that is ready to import. The app itself stays free.
Yes. NvramEditor updates automatically on Windows 10 / 11 (x64).
