Sweet child, he reads the documentations but doesnt use it. I concur with op, to this day, deleting a fucking file in Windows is an unbelievable chore compared to all their competitors. I tried today, nope, couldn't.
I use Windows Defender on several PCs, and have used for years. All are kept up to date on Windows 11 (and prior, Windows 10) and not “modded” to disable telemetry etc.
I haven’t had a “locked by Defender” error in at least 5 years, and I would say more if I could remember the last time I did.
I’m also developing a(n existing) product that actually uses oplocks, so I’m speaking from experience here.
But you dont care, obv you dont use it.
