install from scratch. windows have a hard time managing kernel update. always have a bug or some.
do a fresh clean installation and u will be fine.
if you need to save a file or some use a external hdd(u can borrow from a friend if u don't have one), otherwise you the isn't a software or whatever that you can't find on cgpersia.
or (not recommended) u can use a gparted alike to re-partition you hdd for unused space and copy you important files, then for format only the windows partition.
or u say f*** and erase all and during ur installation divide ur hdd in 2 partitions for failsafe.
or (most recommended) buy a new hdd for data if not a ssd for the os.
