: If Windows is unable to reach a time server or has "Set time automatically" disabled, the slight drift can be enough to block the software. License Expiration or Tampering
: In some cases, WinOLS may believe the date has been "rolled back" to bypass a trial period or license expiration. Recommended Solutions Based on technical documentation like the WinOLS 5.47 Manual Windows Time Guides Sync Time Automatically Settings > Time & Language > Date & Time Set time automatically is toggled to force a refresh from the Windows time servers.

Windows periodically syncs the clock with time.windows.com. If this service is disabled, or if the computer is permanently offline, the system clock may drift (gain or lose seconds/minutes) over time. Even a drift of a few minutes can cause strict security software like WinOLS to flag an anomaly.
