I use Eusing reg cleaner once a month. It makes backups and never gave me any trouble.
Wise Disk Cleaner also once a month. No problems.
To avoid leftovers when uninstalling, I log my installs with Uninstall Tool. No problems but it's payware.
And once a month too, I clean my keyboards, screens, air intakes, &c. ;)
Hmm, it doesn't stop the tracing until all the processes that were launched by the setup are closed, and I think that if the program is lunched by the setup at the end it will keep tracing until the program is closed.
Edit: it also has a force removal option to scan for related folders/registry keys so it might also do it if the setup was traced
Have a look at this thread.
We use uninstall-tool
Good news! I managed to remove the rest of uxstyle! I downloaded "Uninstall Tool" ( https://www.crystalidea.com/uninstall-tool/download ) And used this program to locate all registry entries and files. Unfortunately the "Uninstall force" tool is Premium only. So I just located and removed them manually.
