Image search keeps resetting

This usually happens for one of these supported reasons:

1. The daily set was not completed on time. If a required task is missed before the reset window, the streak goes back to zero.
2. A different time zone or VPN was involved. Microsoft states streaks are based on the device’s time zone, and using a VPN or a device with a different time zone can cause the system not to recognize the streak correctly.
3. The account context changed. If the wrong Microsoft account is signed in, progress may not be counted.
4. Search activity may be limited. Rewards can temporarily limit earning when search patterns look abnormal, such as rapid back-to-back searches, spam-like queries, or automated behavior. When that happens, searches in a period may not qualify for points.

Since this happens on multiple PCs with the same account, the most relevant checks are:

• Make sure the same Microsoft account is signed in each time.
• Complete the task before the daily reset and confirm it shows as completed.
• Avoid using a VPN.
• Make sure both PCs use the correct local time zone.
• Spread out searches instead of doing them rapidly right before reaching the bonus.
• Do not use repeated low-value queries, automation, macros, or anything that looks like bulk point farming.

If the streak or 100-point bonus still resets after that, the next step is to contact Microsoft Rewards Support, because account-specific streak corrections are handled there.
