Fresh Install SFC Error "System32\drivers\bthmodem.sys" Why ?

Question

I've done a clean install. (Media Creation Tool W11)

All drivers updated

Then i scanned sfc. how did it found corrupted files on a fresh install of windows?

Was this driver important?

2023-01-27 11:17:32, Info DEPLOY [Pnp] Corrupt file: C:\WINDOWS\System32\drivers\bthmodem.sys
2023-01-27 11:17:32, Info DEPLOY [Pnp] Repaired file: C:\WINDOWS\System32\drivers\bthmodem.sys

I have installed windows many times so far, I always check with sfc. I have never encountered this error. 

Today, out of curiosity, I did a clean install twice (MCT then Cloud Reset) and again I encountered the same sfc error. 

I guess I'll be paranoid with every install. Is there anyone have an idea ? thanks

Media Creation Tool Windows 11 Install (same sfc error after updating everything after installation)

Then Cloud Reset (same sfc error after updating everything after installation)

Same with release and release preview (.525, 1105, 1194)

I've never had a problem with my Bluetooth devices

Thanks. What does "dism /online /cleanup-image /scanhealth" say?

Answer 4

I always update drivers via windows.

And so far the same drivers have always been installed (I'm checking their versions)

I've never encountered any sfc errors. This time, same scenario, same installation, same drivers.

Even if I do a clean install or cloud reset this time, after updating everything, this error comes up on the first sfc scan. (Tried 3 mct installs and 3 cloud resets in the last two days)

Hi erhan,

I am Sumit, here to assist you with this question.

Probably a 3rd party driver from Broadcom is flagging that as the driver replaced the original file from Windows. Does Windows update indicate a Bluetooth driver was installed?
