1. Installation
After purchase, you will receive an email with a download link for
JINSHI_Setup_v1.0.exe.
Right-click the installer and select "Run as administrator". This is required to apply system-level changes.
2. License Activation
On the first launch, you will be prompted to enter your license key.
- Enter the licence key from your purchase email — nothing else. Its format is
usually
XXXXX-XXXXX-XXXXX-XXXXX. - Do not enter a hardware ID. The app reads your hardware ID by itself, in the background, to tie the licence to this PC. You never need to find it, copy it or type it in, and pasting it into the key box will simply be rejected as an invalid key.
- Ensure you have an active internet connection for validation.
- The bundle issues a separate key for each app, and they are not interchangeable. If a key is rejected, try each of your other keys before anything else — see the support page.
3. Troubleshooting
Antivirus False Positives
Our builds are not code-signed, and the apps modify registry keys and system services — which is also what malware tries to do — so Windows Defender and third-party antivirus flag them. This is the single most common reason an app will not open.
The full recovery steps — restoring the file from Defender's Protection history, adding a folder exclusion, checking a third-party antivirus quarantine, and reinstalling with the exclusion already in place — are on the support page.
"Access Denied" Errors
If you see this error when applying tweaks, ensure you are running the application as Administrator.
Reverting Changes
To undo a single change, switch that tweak back off in the app; the original value it recorded is written back. To undo everything at once, use "Restore Defaults" in the sidebar. Restart the PC if the tweak needed a restart when it was applied. The app does not create a Windows restore point, so if you want one as a fallback, create it yourself before your first run.
4. Network Optimizer
The JINSHI Network Optimizer applies 61+ network-specific tweaks to reduce ping, lower latency, and stabilize your connection for gaming.
What It Optimizes
- DNS Settings: Benchmarks and applies the fastest DNS servers for your region.
- TCP/IP Stack: Tunes MTU, RWIN, Nagle's algorithm, and congestion control for gaming.
- Network Throttling: Removes Windows built-in bandwidth throttling.
- WiFi Settings: Disables power saving, optimizes roaming, and recommends best channels.
- Firewall Rules: Creates optimized rules for popular game ports.
- NIC Tuning: Configures interrupt coalescing, RSS, and buffer sizes.
How to Use
In the JINSHI app, navigate to the "Network" tab to see all available network optimizations.
Click "Optimize Network" to apply all 61+ tweaks. A backup of your current settings is created automatically.
Tweaks are undone one at a time: switch off the individual tweak you want reversed. "Restore Defaults" in the Network tab reverts the settings to the Windows defaults — that is not the same as a snapshot of how your PC was configured before, so if you had tuned any network settings yourself, note them down first.
