Im having the same problem with trials running out so ive been trying these.
Using CCcleaner didnt work, im trying it again though.
DEEP FREEZE is for Mac
I couldnt figure out have to get Trial AIO tools to work
I wasnt sure about Tenant Pro 7 so im not really going to mess with that.
I ran the registry fixer in CCleaner a couple times and it kept picking up issues so i kept running it untill they were all gone. Hopefullly it will work now.
