Why is Ccleaner only going to 98% and not 100%?

Good day to you all...

Windows XP.

I have tried uninstalling and reinstalling Ccleaner.

I have tried putting it on Normal File Deletion, as opposed to Secure File Deletion.

I have all the Applications options checked on.

I found a hint to the solution when I started toggling the Windows options...

In order to get it to work all the way to 100%, I had to uncheck the following Windows options...

IE:

Last Download Location

Autocomplete Form History

Saved Passwords

Windows Explorer:

Search Autocomplete

Other Explorer MRUs

Network Passwords

System:

DNS Cache

Font Cache

Start Menu Shortcuts

Desktop Shortcuts

Advanced:

All options must remain unchecked for Ccleaner to run the full 100%

So, what's the deal? This is only happening on one of my XP computers. The others seem fine.

Many things could cause this:

What is your XP machine like that you are running it on? Specs wise? IE: Single or dual core CPU & rated clock speed/RAM installed.

- Do you know if you have any rootkits or malware on the machine?

- Is it slow running other things?

- Have you defragged it lately?

- How many startup items do you have?

- What version(s) of CCleaner have you tried?

- Does it still do it in Safe Mode, or with a different CCleaner version, or with a portable CCleaner version?

- Do your case/CPU/GPU/power supply fans have dust on them, causing overheating?

What browser do you use?

Are you admin on the machine?
