N3XCare – Safe Windows Maintenance
A native Windows 11 app for safe cleanup, DISM/SFC/CHKDSK repairs, Game Mode control and local application updates through WinGet. No telemetry or aggressive registry cleaning.
N3XCare — safe care for Windows 11
N3XCare analyzes only strictly allowlisted locations and performs every operation only after confirmation. It uses Microsoft tools for repairs, controls Windows Game Mode, and locally checks, updates or uninstalls applications through WinGet. No account, cloud, telemetry or risky registry cleaning.

What N3XCare can do
Analyze before deleting
See the count, size and sample paths. No automatic background cleanup and no hidden categories.
Safe categories
Temporary files, browser caches, thumbnails, shaders, crash reports and Recycle Bin — never Downloads or documents.
Windows repair and optimization
DISM, SFC, CHKDSK /scan, WinSxS analysis and optimization selected by Windows for SSD or HDD — always with a live log.
Hard safety boundaries
The backend re-enumerates files from a closed list of directories, skips links and never accepts an arbitrary path from the UI.
History and HTML report
Recent operations, results, skipped files and reclaimed space stay local and can be exported.
Restore point
Before system changes N3XCare can create a restore point and clearly reports when Windows does not permit it.
Game Mode in one place
See the current state and enable or disable the official Windows Game Mode setting.
Applications and updates
A local app inventory, update checks and deliberate uninstalling through WinGet with system-component protection.
Getting started
- 1Download the installer, install N3XCare and launch it. Regular analysis does not require administrator privileges.
- 2Select “Analyze system”, review the categories and choose only what you want removed. N3XCare selects low-risk items by default.
- 3Use the Applications section to check for updates or uninstall a selected program. N3XCare requires confirmation and blocks protected system components.
Note: the app is not yet EV code-signed, so Windows SmartScreen may display a warning. Installers and automatic updates are signed with the N3XCare updater key and verified by the app.
Changelog
- FixTicking an item in any list no longer scrolls the view back to the top — this affected the starter set as well as the filters and selections in Applications.
- ImprovementEvery program in the starter set carries a one-line description of what it actually is, in Polish and English.
- NewStarter set: a curated list of programs for a freshly set up computer, installed in one pass through Windows Package Manager.
- ImprovementThe install queue shows each package separately and tells "already installed" and "restart required" apart from an actual failure.
- ImprovementUpdates pin the winget source, so an id shared with the Microsoft Store is no longer ambiguous.
- FixBattery health now reads the values even when the driver publishes only some of the WMI classes — such a laptop previously showed no data at all.
- FixThe driver's "unknown" sentinel (0xFFFFFFFF) is no longer treated as a measurement, which could show a worn battery at 100% health and fully charged.
- ImprovementWhen the WMI classes report no capacities, N3XCare takes them from the powercfg report — the same one that reads the battery straight from its driver.
- ImprovementWhen Windows returns no readings at all, the section explains why and lists the per-class WMI responses instead of vanishing without trace.
- NewBattery health: full charge capacity against the factory capacity, charge level, cycles and power state — plus the full powercfg report.
- ImprovementThe HTML report includes the battery figures and can be saved even before any operation has been run.
- NewBulk application updates, update holds and inventory export.
- FixFixes to the application inventory and maintenance history.
- NewGame Mode and installed-app management.
- NewWindows Explorer appearance repair.
- ReleaseFirst release: safe Windows cleanup and repairs with Microsoft-supported optimizations.
