i do know that type of cleaners you talk about i tried them out and would cause my computer to stumble around for a few minutes seemed real hard on computer because almost all over loads the memory to flush it out which makes the computer almost un-usable for a few minutes but this one runs in the task schuduler and calls on windows to do the cleaning so it doesn't do the cleaning windows does because its built into windows i babysat it for like 2 months after installing using Mark Russinovich Process Explorer and it only comes on when the task scheduler told it and only stays on for a second the only thing i had to put on the ignore list is window blinds because dragging explorer folders around it wouldnt show contents but i believe thats only because window blinds replaces some files like uxtheme.exe and a few more but loads into system memory also this has a optional notification icon that i never hide heres pic i just thought it was strange when it hit 50 percent memory use never seen before so i thought id say something i come everyday to the forum and try and follow the tutorials but even with all the plugins its still has a lot to do with art and skill ive tried almost all of the free graphic programs out there and didnt like none of them paint.net its the only one designed right in my book
