Windows 10 c drive full ??

Friends we are daily facing this issue for disk full that time clean junk file and folder and defragmentation
But there might not resolve our issue

We need to delet some.other step are

Disable windows update service in services

And one more clean folder on path

Windows/softwaredistribution/download

Inside all stuff clean

Now you can see your c drive space increase as before one
