Everything You Need to Know About Assistools and Its Features
A good maintenance software should be fast, reliable, and ready to use instantly—without requiring installation or complex configuration.
That’s exactly what Assistools delivers: a tool designed to clean, repair, and optimize Windows (7, 8, 10, 11) in a single click, while keeping the system lightweight. It can be run directly from an external hard drive or USB stick and leaves no traces after use, following a fully portable and minimalist approach.
Developed in Rust for Faster and Safer Code
Assistools is developed in Rust, a modern language created by Mozilla, designed to replace C++ by enhancing both security and performance.
Rust is known for its strict memory management, significantly reducing the risk of crashes or resource leaks. Assistools’ code is compiled into a lightweight executable, ensuring smooth performance—even on older machines.
A Tool Designed for IT Technicians Seeking Maximum Productivity
From its design, Assistools has been built to be portable and independent of the host system.
You copy it to a USB drive? You run it on a computer? You open it on another machine? No problem. There’s no need for installation or registry entries, ensuring that no residual data remains if the tool is deleted. This portability is invaluable for technicians who work on multiple computers or for any user who simply wants to keep a maintenance system readily available.
Assistools is primarily designed to be fast and discreet. The idea is not to monopolize resources during its operations. It can clean temporary files and repair system files while allowing the user to continue working. Even on older configurations, the application runs responsively without impacting the overall performance of the computer.
Des interventions en profondeur pour réparer Windows
Contrairement aux outils de nettoyage classiques qui se limitent à supprimer des fichiers temporaires, Assistools adopte une approche plus avancée en exploitant des fonctionnalités natives de Windows. Son objectif est d’améliorer la stabilité et les performances du système en appliquant des correctifs et des optimisations automatiques, sans nécessiter d’intervention de l’utilisateur.
Toutefois, certaines options plus avancées (comme la gestion de la mémoire virtuelle ou la modification de certains services Windows) restent accessibles dans d’autres onglets pour les utilisateurs souhaitant un réglage manuel. Le mode automatique, en revanche, s’appuie sur trois grandes interventions profondes basées sur des outils intégrés à Windows.
System Repair with DISM and SFC
When the user initiates an automatic maintenance, Assistools performs an in-depth check of the operating system’s integrity by running the following commands in the background:
- DISM (/Online /Cleanup-Image): This powerful Microsoft utility scans and repairs damaged system files by comparing the Windows image with a healthy version stored on Microsoft servers. It helps fix errors that could prevent Windows from functioning normally.
- SFC (/scannow): The System File Checker scans all protected system files and replaces corrupted ones with correct versions.
These two tools combined allow for the restoration of an unstable Windows system without requiring a full reinstallation.
Advanced Cleanup of Unnecessary Files
Assistools goes beyond simply clearing standard temporary files. It performs a selective and intelligent cleanup of system directories using internal commands and PowerShell scripts.
The cleanup operations include:
✅ Removal of Windows Update cache files, freeing up space and preventing conflicts during updates.
✅ Cleaning of internet application caches (browsers, third-party applications), improving the responsiveness of software.
✅ Deleting obsolete restore points, keeping only recent backups to recover disk space without compromising security.
✅ Automatic emptying of the recycle bin, freeing up space without manual intervention.
This cleanup does not delete any personal files, and only unnecessary data is removed, ensuring no risk to the system.
Automatic Disk Optimization (HDD and SSD)
Assistools tailors its optimization process based on the type of storage media detected:
🔹 For an SSD (Fast Electronic Drive):
The tool runs the ReTrim command (Optimize-Volume -ReTrim), which optimizes memory block allocation on the SSD. This preserves the drive’s lifespan and boosts its performance.
🔹 For a Mechanical Hard Drive (HDD):
Assistools applies defragmentation (Optimize-Volume -Defrag), reorganizing files optimally to speed up access times.
This optimization runs in the background and does not interrupt the PC’s performance during execution.
A Fully Automated and Secure Process
Assistools works in perfect synergy with Windows’ native components (system files, registry, disk management) and does not add any third-party elements.
The user does not need to intervene: a simple click triggers the maintenance routine without any manual configuration.
💡 Note: If you are using other specialized tools for storage management or Windows repair, Assistools will not alter anything or replace any third-party software. Its operation is 100% compatible with existing optimization solutions.
PowerShell at the Helm: Everything Runs in the Background
Although the interface and core logic of the software are written in Rust, the automation is largely powered by PowerShell.
As soon as the user initiates the automatic maintenance, Assistools calls a series of pre-written scripts to:
- Clean the disk (temp files, recycle bin, prefetch, old restore points, etc.)
- Invoke repair tools (DISM, SFC)
- Update and scan the system with Windows Defender or Avast
- Optimize disks (TRIM or defragmentation)
- Perform Windows updates with PSWindowsUpdate
The great advantage of PowerShell is its excellent integration with Windows: it allows manipulation of registry keys, automation of standard commands (cmd.exe), and management of processes and services. The auto mode relies on these scripts at each maintenance step. The user doesn’t need to do anything manually—everything is hidden behind the graphical interface, and Assistools ensures the proper execution of each command before proceeding to the next.
Enhanced Security with Microsoft Defender and Avast One
Assistools’ antivirus protection relies on an automated and semi-intelligent system for protection without requiring manual user intervention. The tool adopts a two-step approach depending on the available security solutions on the system.
Priority to Microsoft Defender:
By default, Assistools uses Microsoft Defender, the built-in Windows antivirus, for native protection without adding third-party software. It automatically performs:
- Signature updates via the -SignatureUpdate option to ensure the latest virus definitions are downloaded.
- A quick system scan with -Scan -ScanType 1, which detects and neutralizes common threats without affecting computer performance.
Alternative with Avast One:
If Microsoft Defender is disabled or absent, Assistools automatically switches to Avast One (if installed on the system). In this case, the tool performs:
- Virus definition updates via ashUpd.exe to ensure the Avast threat database is up to date.
- A silent quick scan triggered by ashQuick.exe, with automatic removal of detected threats. This scan runs in the background without disturbing the user.
If another third-party antivirus (Norton, ESET, Bitdefender, Kaspersky, etc.) is installed, Assistools does not intervene or make any changes. The protection feature is simply ignored to avoid interfering with the existing security software.
Thanks to this intelligent management of antivirus solutions, Assistools ensures basic protection without user intervention while respecting existing setups. The goal is to maintain optimal security levels without conflicts with other software and without requiring complex configurations.
