Changes in v5.45 and your feedback in CCleaner Discussion Posted September 10, 2018 · Report reply - System setup: See my signature !!!! - I will report back with more info. Your reply gave me some clues - Suggestions: 1) Make sure that this monitoring feature runs with a (much) lower priority. 2) CC can be set up to run upon start up. But I also know that Windows performs A LOT OF disk I/O in the first say 2 to 5 minutes after the user starts his/her computer. That could interfere with CC. Perhaps Piriform can build in a "start up delay" of anything between say 2, 3, 4 or say 5 minutes ? (I know 2 programs that have such a "start up delay").
