Will test it shortly. Update: Doesn't crash anymore.

Clean? Well, the "usual" install of CCleaner, meaning each update over the last one for a long time now. Latest Windows 10 Home (20H2, 19042.662, Windows Feature Experience Pack 120.2212.551.0) with no extra av or firewall. But, the crashes happened on 19042.630 first. Anyway, I have CCleaner uninstalled currently.. Will wait for the next version.

Yep... This crash is logged every time now on app exit: Description Faulting application name: CCleaner64.exe, version: 5.74.0.8198, time stamp: 0x5faae541 Faulting module name: CCleaner64.exe, version: 5.74.0.8198, time stamp: 0x5faae541 Exception code: 0xc0000005 Fault offset: 0x0000000000d68253 Faulting process id: 0x2e38 Faulting application start time: 0x01d6c6e9f2c686f4 Faulting application path: C:\Program Files\CCleaner\CCleaner64.exe Faulting module path: C:\Program Files\CCleaner\CCleaner64.exe Report Id: 4303b16b-aac3-4744-b9dc-c5b37abe6f95 Faulting package full name: Faulting package-relative application ID:

Nevermind, the shell extension does not work even after rebooting, oh well.

I can answer "[*]Does the scheduler run Defrag or Quick Defrag?" -- It definitely runs full Defrag, and is painfully long. So much so that I don't think I can use Defraggler in its current state, it may be more thorough and all than Win7's own app but the time it takes just isn't worth it to me.

Hello. I use Win7x64 and just installed Defraggler 2.04.297. The Explorer shell extension commands won't do anything for some reason. I right-click on a selected file or folder, and nothing happens when I select check or defrag. Do I actually have to reboot to get the shell extension to work properly? Thanks
