Aurora Optimizer · Maintenance and speed-up for Windows
Aurora Optimizer examines your disk, free space, startup, startup programs and registry, and tells you in plain language what it found and why it suggests a change. It changes nothing until you choose; it backs up every change first and lets you undo it from History. When it cannot measure something it says "unknown" instead of making up a number.
Three promises
The biggest risk in maintenance software is sweeping changes made without asking. That is why Aurora Optimizer only looks first.
Scans only read. Nothing is pre-selected in the cleanup, leftover or duplicate lists; every suggestion says what it is, why it is suggested and what will be done.
Registry changes are first saved to a .reg file and leftover folders to a ZIP archive; if the backup cannot be written, nothing is deleted. A system restore point is also created before changes.
Startup time and startup impact are read from Windows' own records; if they cannot be read it says "unknown". If startup did not get noticeably shorter after a change, it says "No clear gain".
What it looks like
Tabs at the top switch between sections; every screen shows the current state first and the buttons that change something come last. The screens below are sample views of the real interface, taken in a test environment with test drives and sample programs; names and numbers are examples.
What it can do
Features with a Beta badge are built and tested in a test environment, but have not yet been tried with real programs in the acceptance run on a real computer.
Shows which regions of the disk hold contiguous, fragmented or system files; click a dot to list the files there. On an HDD, defragmentation uses the safe file-moving path Windows provides: each file is re-read at every step, the job can be stopped at any time, and system and in-use files are skipped.
Whether a drive is an SSD or HDD is read from Windows' device information. Defragmentation is never suggested on an SSD; Windows' own optimise tool is run with the TRIM command instead. Disk health (temperature, wear) and a read-only bad sector scan are here too.
Temporary files (older than 7 days and not in use), Windows Update leftovers and the Delivery Optimization cache are cleaned with Windows' own commands; the thumbnail cache, error reports, browser caches and the Recycle Bin with separate confirmation. Downloads, Documents, Desktop, Pictures and OneDrive, and cookies, passwords and browser history are never cleaned.
Shows the folders taking the most space and the 100 largest files on the drive or folder you choose; every row has "Show in Explorer". There is no delete button on this screen: you decide what goes.
An exact duplicate is a file with the same content hash (SHA-256); name and date do not count. The same photo at a different size or quality is shown separately as a "similar image" and none of them is selected automatically. Selected files only go to the Recycle Bin; the last copy in a group cannot be selected.
Recent startup times and the apps, services and drivers that slowed startup are read from Windows' measurement. It suggests turning off high-impact startup programs, setting third-party services to "Delayed start" and the Fast Startup setting; services are never turned off.
Switches between the power plans already in Windows (no new plan is created). Shows the top 10 users of processor, memory and disk; the program never ends a process.
Disk health and Windows Security status (with a warning if protection is off) are shown on one card. Windows files are checked and repaired with Windows' own tools (DISM and SFC). A system restore point is created automatically before changes; if Windows did not create one, it says so.
This is not a "registry cleaner". It only finds broken entries proven to point to a file or program that no longer exists, and explains what they are and why in plain language. Each entry is re-checked and backed up before it is applied.
Programs that start with Windows, the Startup folder, tasks that run at sign-in and automatic services in one list. The publisher is read from the program's digital signature; Windows components are locked.
Removes a program with its own uninstaller, then finds leftover folders and registry keys using exact matches only. Leftovers are backed up first, deleted when you choose, and can be restored from History. Windows components cannot be removed.
Lists the updates found by Windows Package Manager; you choose which to install, and each update runs one by one with confirmation. There is no bulk "update all".
If you turn it on, it scans once a week and only reports: space that can be freed, new high-impact startup items, broken registry entries and disk health warnings. It never applies anything by itself; turning it off deletes the task.
Asks the open apps you select to close and switches to the High performance plan if there is one. An app that refuses to close stays open; nothing is force-closed. Turning game mode off restores the old power plan and reopens the apps it closed.
On laptops, the battery's current capacity against its design capacity and its charge cycles are read from Windows' battery report. Without a battery this section does not appear.
Advertising ID, suggested content, tips and similar Windows settings on separate cards; each card shows what changes and the Windows default. Only your own user account's settings change; the old value is backed up and can be restored.
The interface is available in Turkish, English and 19 more languages; Arabic and Urdu are shown right to left. Turkish and English are complete; the other translations have not yet been reviewed by native speakers.
Measured and written down
On 9 and 10 October 2026, acceptance runs were made with administrator rights on a real computer running Windows 11. Defragmentation was tested on a USB stick with test files written in pieces; the other steps used the computer's own disk and settings. Every change was undone afterwards.
| What was tested | Result | How it was verified |
|---|---|---|
| HDD defragmentation · test files written in pieces | Files ended up in one piece | Fragment count with Windows' fsutil tool; SHA-256 of every file identical before and after |
| Stopping defragmentation halfway | Files stayed intact | SHA-256 values identical after stopping; chkdsk (read-only) found the file system consistent |
| System disk type (NVMe SSD) | Recognised as an SSD; defragmentation not suggested | Windows device information: NVMe with TRIM support |
| Delayed start on a third-party service | Applied, then restored | Windows service manager's own query (sc qc) |
| Trying to delay a Windows service | Refused | Windows services are locked |
| Power plan switch | Switched, then back to the old plan | Active plan read with powercfg |
| Registry scan | Nothing in the registry changed | SHA-256 of exports before and after the scan identical |
| Trying to uninstall a locked Windows component | Refused | The program never ran the uninstaller |
| Defragmentation, delayed start and power plan change without a licence | None of them happened | The User edition refused without a licence |
What we leave out on purpose
We do not add tools that are common in maintenance software but show no measurable benefit or can do harm.
Windows uses spare memory as a cache and frees it itself when needed. Forcing memory free can make programs load again shortly afterwards and slow things down.
Extra entries in the registry do not slow Windows down measurably; deleting them in bulk can break programs. That is why we only suggest proven broken entries and back them up first.
Your connection speed is set by your internet provider and your network. Tweaking Windows network settings usually makes no difference and sometimes breaks the connection.
Limits
Knowing what a maintenance program cannot do matters as much as knowing what it does. We say it up front:
We do not promise speed. We show whether a change helped by comparing startups before and after it with Windows' own startup measurement, and if the difference is small we say so.
Free use and licence
Scans, maps, measurements and suggestions are always free. A licence is needed to apply a change (defragment, clean up, uninstall, change a setting). Aurora Optimizer is not sold separately: it comes with the Aurora One Licence.

FAQ
We do not give a number, because the result depends on the computer, the disk and the installed programs. Aurora Optimizer compares startups before and after a change using Windows' own measurement and shows you the result.
If the difference is small it says "No clear gain"; if you have not restarted yet, it asks you to restart for the comparison.
Yes. Registry, startup, service, power plan, privacy and leftover changes are backed up before they are applied and can be undone from History with one click; undo never needs a licence.
A system restore point is also created before changes. If System Protection is off, the program asks: turning it on, continuing without a point or cancelling is your choice.
No. SSDs do not need defragmentation and it only wears them. Aurora Optimizer recognises SSDs and only runs Windows' own optimise tool with the TRIM command.
No. We do not promise speed by "cleaning" the registry. The program only finds entries proven to point to a file or program that no longer exists, and backs them up before applying anything.
Disk cleanup never enters the Downloads, Documents, Desktop, Pictures or OneDrive folders; cookies, passwords and browser history are not deleted either.
For duplicate files, only the files you select are moved to the Recycle Bin, where you can restore them. The large file map has no delete button.
Scans, cleanup and maintenance happen on your computer. The only time the program goes online is the licence check; only the licence key and a hash of the device ID are sent.
Program updates are downloaded by Windows Package Manager (winget), and files needed for Windows repair by Windows itself.
Yes. Scans, maps, measurements and suggestions are free; you see what would be done without a licence. A licence is needed to apply the suggestions.
Aurora Optimizer is not sold separately; it is used with the Aurora One Licence, which covers every Aurora One program. Download and sales are not open yet.
