Our verdict: LockHunter solves the "file is in use" error: right-click the file and it shows which program holds it, then unlocks or deletes it. Deleted files go to the Recycle Bin, which makes mistakes recoverable. Killing processes or unloading DLLs can still crash programs, so use it with care.
About LockHunter
LockHunter is a free tool for files that Windows refuses to delete or move because another process has them open. It integrates into the Explorer context menu and lists every process locking the selected file or folder, with details about each one.
From that list you can unlock the file, delete, rename or copy it, kill the locking process or schedule deletion at the next restart. Unlike many similar tools, LockHunter moves deleted files to the Recycle Bin. The developer also mentions its use against malware that blocks its own files.
What it does well

- Delete at restart. Schedules removal for the next Windows start.
