Bring context, not secrets.
A concise description makes troubleshooting easier. Remove private information from screenshots and error text before sharing.
Do not share license keys, passwords, payment details, or full unreviewed system data.
- 01 Your Windows version (Windows 10 or Windows 11, 64-bit).
- 02 The app version shown in YUKFUE, if visible.
- 03 Whether you are using Free or PRO.
- 04 What you clicked and what happened next.
- 05 A screenshot or the exact error text, with sensitive details removed.
- 06 Whether YUKFUE was running with administrator access.
- 07 Which area is involved: download, activation, benchmark, Restore Center, or a Windows warning.
Download and release status
Use the official Download page.
The Download page provides the official GitHub installer URL, exact filename, version, SHA-256, and a PowerShell verification command.
Use that official path and match the published details. Do not substitute random reuploads, guessed filenames, mirrors, or binaries posted in chats—including Discord.
Verify the official release →SmartScreen and security
A warning deserves context.
The current installer is not code-signed, so SmartScreen may show publisher/reputation messaging. That is not the same as an antivirus detection, and neither message is a safety guarantee.
Do not blindly ignore or disable Windows security. If the source, file details, or warning details do not match the official page, stop and verify before running anything.
PRO activation
Buy. Receive the key. Paste it in the app.
PRO is purchased through Gumroad. Gumroad emails the license key; open YUKFUE’s license/activation dialog and paste it there. For key or transfer issues, use the support contact shown in the app or on the Gumroad page.
Never post your license key publicly.
Benchmark questions
Compare your own before and after.
The benchmark compares responsiveness signals on your PC. Hardware, drivers, thermals, background activity, and normal run-to-run variance can affect results. It does not guarantee FPS, latency, or a Fortnite outcome.
Restore Center
Restore supported changes.
Supported changes can be restored individually through Restore Center. Rare one-way actions are labeled before use. Restore Center is not a full-system backup, so read labels before aggressive or advanced changes.
Verified community support
Continue the conversation in Discord.
The verified YUKFUE Discord is the documented community and support channel. It is useful when an issue needs discussion, but it does not come with a response-time promise.
Do not post license keys, passwords, payment details, or other sensitive information. A binary shared in chat is not an official release; use the official Download page for release files.
Open verified DiscordOPTIONAL DIAGNOSTIC CONTEXT
Export Support Bundle
YUKFUE includes an Export Support Bundle control that creates a sanitized diagnostic zip. You decide whether and when to send it for troubleshooting.
- 01Use the in-app Export Support Bundle control.
- 02Review what you plan to share and remove anything you do not want to send.
- 03Share it only when you choose to ask for troubleshooting help.
Choose the next step
Start with the answer closest to the issue.
Use the FAQ first, check the official download status, and keep benchmark and safety context close.
