Well, this issue happens with updating or reinstalling as well, not just with uninstalling. From what I get is when either uninstalling 7-zip or updating it with 7z2408-x64.exe, the 7-zip.dll.tmp file is being created and the original 7-zip.dll file is being marked for deletion. After a reboot, the original 7-zip.dll is being deleted and 7-zip.dll.tmp renamed to 7-zip.dll. If a cleanup tool deletes 7-zip.dll.tmp before reboot then after a reboot the original 7-zip.dll gets deleted and that's it,...
