Cache reset when waking from sleep or random cache reset please read

Creztor:   I believe one of my cache resets MAY have been caused by a Windows Update – these are a known possible cause of cache resets.   This update was the late April one where Microsoft fixed the security issue that affected Internet Explorer back to version 6, although other issues may have been addressed as well.     Not sure this was the cause as the cache was fairly full at the time.
