Sometimes with Windows, I come across issues where I can’t delete files on my hard drive because I “don’t have permission” to delete them. I typically tend to come across the issue after Windows has installed Windows updates – I end up with garbled folders that I can’t modify or remove.
Thankfully, there is a solution. I’ve come across a program called Unlocker – which is a Windows extension that forces files to delete even if your user can’t.
It’s free and can be downloaded here. Use it with care (don’t remove any files by mistake), but it can be a great tool for removing temporary files.
