CCleaner v5.63.7540 crashing in Windows 7 in CCleaner Bug Reporting Posted January 17, 2020 Nukecad, Thanks for feedback. Yes i did know about the windows 7 to 10 upgrade license issue still working. I am a PC troubleshooting, upgrade and repair hobbyist and help family and friends alot so i did know about that. I also listen to quite a few PC repair tech podcasts and some others ones which mentioned this several times. Goid info though for others who might come across this. Again thanks for this forum to post comments, issues and such. I always forget to check forums when i run into things that i have never seen before. Have a good year.
