I accidentally deleted monitor.sys files from the system32 folder
- System: windows 10 64 bit
- Battery or AC: battery
- Model: a416ja
well I don't know why I did this but, I deleted monitor.sys from the system32 folder and I replaced it with my brother lenovo monitor.sys files, thought it is just the same things. And guess what, my generic pnp monitor driver got error. suddenly my brightness can't be adjusted. The option for brightness just gone and missing. I can't find it anywhere. My keyboard shortcut for adjusting brightness also not functioning. And I'm going crazy cuz I don't know what else to do and the fact that it is my stupid doing is just so stressful.
I don't have any backup
I tried everthing, update, uninstall, enable, disable the driver. troubleshoot. cannot fixed.
Thought of rebooting my laptop, but I'm scared it'll not work.
wonder if upgrading my windows 10 will reset all the drivers or not. I dunno anymore..
