update

Now, let's address some frequently asked questions:

1. Skip Hits: We've thoroughly checked the code and found no issues with skip hits. Tzi has retries for Fake2fa and FakeBad. msBanHits are categorized, but msBanHits are not counted in hits; they exist independently. This explains why you might feel there are fewer hits. In fact, they aren't being counted, but they're still in your folder.

2. When to Fix AutoBuy: Since this feature requires monthly payments for proxy and server maintenance after being made free, we're very busy and don't have much free time to maintain it. We also need to frequently update and maintain bypass functionality, so we can't guarantee it will work in every version. We'll consider fixing it in the next version.

3. Speed ​​Low: Microsoft has changed to a completely new framework, adding more rate limits and anomaly detection in many request areas. As you've seen, many hits will display a login failure message like "You have attempted to log in too many times with an incorrect account or password." This is Microsoft's limitation on high-concurrency, high-request checkers and will not affect normal users. Tzi checker is currently the fastest checker on the market.

Also, Checker now updates automatically, so minor updates will no longer send notifications. You can simply restart Checker yourself.

Optimize missed hits issue.

This version is a transitional version. The next version will include a debug mode for saving logs for my analysis.

The points system is now available.

Also, let me explain the two bypass modes.
Both bypass methods are for testing.
Both can be enabled simultaneously. Beta2 runs before the beta version.
If you find any leaks in the first beta, adjust the fakebad setting to 3-5; this will reduce speed.
The second is pre-detection, filtering data; this is 100% accurate.

From Paid to Free
Starting with version v1.76, Tzichecker has officially become a completely free tool.
Tzichecker previously operated as paid software; I am grateful to all paid users for their continued support and trust. After careful consideration, I have decided to make Tzichecker free for all users, with no feature restrictions and no distinction between free and paid versions.
All features are completely free—no stripped-down versions, no limitations, and no in-app purchases.
No further fees will be charged, and existing paid users do not need to renew their subscriptions.
Ongoing updates and maintenance will continue, and future versions will also be free.
Thank you to every early paid user; your support is what has brought Tzichecker to where it is today.
