Answer:
anytime
Explanation:
as far as i know you can manage in real time meaning add or remove any hardware or software anytime but im not sure once its rewritten each is considered version 1.0 but uninstallation happens each time you reinstall so uninstallation is actualy anytime
last i checked all tho trial activation is usualy one week or one month so 7 or 30 days till installation but uninstall is anytime unless it service or updates
