Can I clear the Prefetch folder?

Hi,

I have my old laptop and my new laptop. My old laptop gets barely usable so I was trying 5 days to clear it somehow just for fun.

While exploring the Windows folder to find something useful or useless, I found the Prefetch folder. At first it was locked so I clicked Continue to see if it will let me in.

On my old laptop there is 622 files and folders, and the folder itself weights about 200MB(!). On my new laptop, it's only 16MB like nothing.

At first I didn't want to get in here, so in the browser, searching "can I clear the Prefetch folder" doesn't give me any normal results. Everything was about the Prefetch folder, which I know it contains cache for processes if I am saying that right, but not about if I can delete something from it.

And that's why I am here. My question is, can I delete the unusable program files from the Prefetch folder? No, not the folder itself or all its contents. I want to delete the files for programs I already uninstalled, not just uninstalled, uninstalled even their last files until to the last hidden file and registry entry.

The reason why I am afraid to do this is because the folder itself is located at C:\Windows directory, meaning deleting at least one file, and there one component is broken. I just need to know, is it completely safe to delete uninstalled program files from this folder?

A reply and help would be greatly appreciated!
