Most trial software (Photoshop, JetBrains, Notion) ties the trial to a hardware fingerprint. After 30 days, the trial "expires" — for that hardware. An HWID change resets the counter.
Technically this works in 90% of cases. Practically it's a vendor ToS violation. We do not endorse using HWIDChanger to reset trials — that's not a legitimate use case.
Legitimate scenarios where the same operation is fine: testing software in QA labs, evaluating products on multiple hardware profiles, post-purchase reactivation after upgrade.
If you genuinely want to extend a trial — talk to the vendor. Most offer extra evaluation periods on request. Far more reliable than HWID gymnastics.
