CRY is a tool that changes real Windows settings. It is built to be safe and reversible — but it operates on your system, at your direction. Please read this before you optimize.
The short version. CRY makes real changes to Windows — registry keys, services, scheduled tasks. It shows you each change verbatim, creates a System Restore point first, and keeps a local change log so everything is reversible. But you run it on your own machine, at your own risk. The software is provided “as is”, with no warranty. Make a restore point, read each card, and only apply what you understand.
This page is the acceptable-use and disclaimer notice for CRY Free Optimizer (the “software”), a free Windows utility made by CRY. It works alongside the Terms and the EULA; where those documents are more specific, they govern. By downloading, launching, or applying changes with CRY, you confirm you have read and accepted what follows.
CRY is not a cosmetic tool. When you pass the review gate and apply a tweak, it makes genuine changes to your operating system, which may include:
DiagTrack or dmwappushservice).netsh.winget or appx (reinstallable later).Some of these changes require Administrator rights and may need a sign-out or restart to take full effect. CRY launches non-elevated and only requests Administrator at the moment you apply a change that needs it — you can cancel that prompt with no side effects. Even safe, well-tested changes can interact with your specific hardware, drivers, software, or configuration in ways no tool can fully predict.
Before applying changes, CRY creates a System Restore point as a coarse, whole-system fallback. This is part of how the software is designed to keep you safe — but it depends on Windows.
A restore point is a safety net, not a guarantee. It is one of several reversal mechanisms, described next.
Reversibility is a core design goal, not a marketing line. For each change you apply, CRY captures the previous value and writes it to a local, append-only change log under %LOCALAPPDATA%\CryOptimizer. From there you can undo:
Removed apps can be reinstalled later — for example through the built-in App Installer. If you delete the %LOCALAPPDATA%\CryOptimizer folder, CRY loses the precise per-tweak undo history for past changes; the System Restore point remains as the coarse fallback. Reversibility is real and thorough, but it is not a promise that any individual undo can recover from a separate, unrelated failure of your system.
You use CRY at your own risk. Because the software changes system settings, it is possible — even when used as intended — for changes to produce unexpected results on a particular configuration, such as a setting that you preferred the other way, an app that needs reinstalling, or behavior that requires a restore or a restart to resolve. By using the software you accept this risk and agree that you are responsible for your decision to apply any change.
To use CRY safely, you are responsible for:
cryset: code you paste in. Imported selections still pass through the same review gate — inspect every change before applying, exactly as you would your own.CRY is provided for lawful, legitimate optimization of computers you own or are authorized to administer. You agree not to:
cryset: code does, or share presets designed to harm or mislead another user.If you are administering machines for others, you are responsible for confirming that the changes you apply are appropriate and permitted in that environment.
The software, this website, tweak descriptions, presets, and any documentation are provided for general informational purposes. They are not professional advice for your specific situation. A setting that helps one configuration may be neutral or unwanted on another. If you are unsure whether a change is right for your machine, your workload, or your organization’s policies, consult a qualified IT professional before applying it. You are responsible for evaluating the suitability of any change for your own use.
The software is provided “as is” and “as available”, without warranty of any kind, whether express, implied, or statutory. To the fullest extent permitted by applicable law, CRY disclaims all warranties, including the implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.
We do not warrant that the software will be uninterrupted, error-free, or that it will achieve any particular performance result, that any reversal mechanism will recover from every situation, or that it will be compatible with every hardware, driver, or software configuration. No statement — written or oral — creates a warranty beyond what is stated here. Some jurisdictions do not allow the exclusion of certain implied warranties, so some of the above may not apply to you.
To the fullest extent permitted by applicable law, in no event will CRY (or its contributors or suppliers) be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of data, profits, goodwill, or system availability, arising out of or relating to your use of (or inability to use) the software — even if advised of the possibility of such damages, and regardless of the legal theory.
Because CRY is provided free of charge, to the extent any liability cannot be excluded, the total aggregate liability of CRY relating to the software is limited to the amount you paid for it — which is zero. Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above may not apply to you; in that case, liability is limited to the smallest extent permitted by law. Nothing here limits liability that cannot be limited under applicable law.
This disclaimer is governed by the laws of the jurisdiction in which CRY is established, and references to the maker refer to CRY where a legal entity is required.
CRY is deliberately built to be the opposite of the typical “optimizer”. We make these commitments about how the software behaves:
This statement describes our intent and design; it does not expand the warranties disclaimed above. It does mean that if you ever find a change that is misleading or purely cosmetic, that is a bug — please tell us.
