I'm french, so i'll try to write good English ! Sorry if not !
1/ First thing : i was very VERY desappointed when i saw that you deleted "check update" option !
I use Ccleaner since severals years, at least 8 years !... and i always updated it myself every 5-6 month, or when i changed OS (windows versions).
Then now, i always have an annoying notification to update each time i launch it, until i update, or until next update (can't have peace more than a month thus).
2/ Now (since v541) you put a new interface.... FULLY USELESS for me !!
And worth, i suppose it use Graphic Card drivers because of GC overlay appearance each time (like a game launching !!). For what hell CCleaner needs to use graphic card performances ??
For the useless new interface ?... so... give me a way to delete this New Interface Fully Useless (NIFU) !!
3/ I updated CCleaner (forced, because bored with notification) , and (i wasn't accustomed to be on defensive with you !!), I found myself with Mc Afee !! Ohhh!! There was an option to uncheck !!! First time i see that whith Ccleaner !
4/ Today, the vase overflowed : forced to update another time !!.... and after execute.... Chrome lost my profile !! ==> must re-log to find all my parameters !!
So!! Now (*i just created an user account only for this post, on this forum !*) :
I uninstalled CCleaner, and came back to the v538 version !
I won't update it until you persevere in this way ! I have peace (i unchecked "check update" option)... but i'm sad !
I recommended Ccleaner i don't know how many times ! I installed it myself for folks and family !
But for the moment, i won't recommend it for nobody ! I can't tell someone "yeah, install it and you'll have another programm that bore you with notification" !
I'm sad because, it is an excellent tool, wasted by superfluity !
I'm sad because, perhaps I will be obliged to definitively uninstall it when Windows will be too much updated !
