How is it possible for a clean install of windows to have corrupted or missing DLLs and SYS files?

[Guest]

I'm just not sure how that's possible. It's happened to me before and I just want to know what the deal is.

Bad download? Bad media tool file? Antivirus deleted or quarantined something?

Are you getting bsod or just random errors? What is reporting the bad sys files?

right click start button
choose command prompt (admin)
type SFC /scannow and press enter

this scans system files and may fix this behaviour
once its run, even if it finds no errors, copy/paste below into same window
DISM /Online /Cleanup-Image /RestoreHealth

SFC fixes sys files, DISM fixes the files SFC uses to fix files. So if SFC had errors before DISM, re run it again and restart PC afterwards

BSOD are normally drivers so installing old drivers can create these problems. If who crashed just blames NTOSKRNL then you might be best posting dump files instead:
Can you follow option one here: http://www.tenforums.com/tutorials/5560-bsod-minidump-configure-create-windows-10-a.html
and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD

that creates a file in c/windows/minidump
copy that file to documents
upload the copy from documents to a cloud server and share the link here and someone with right software to read them will help you fix it

or just go here and follow their instructions as they have more people who can read those files: http://www.tenforums.com/bsod-crashes-debugging/

Thanks for the tips 😀 but i mostly made this thread to ask why it happens in the first place and what the causes could be.
