Microsoft was better at software in the ’90s, and these still-useful Windows utilities prove it

Microsoft PowerToys originated during the development of Windows 95 as small programs created by engineers to test concepts and ease workloads. The first collection of PowerToys included tools like FindX, Send To X, and Tweak UI. System Configuration (MSConfig) helps isolate configuration and startup issues by allowing selective loading of services and startup components, remaining useful despite modern management shifting to Task Manager. Disk Cleanup was launched with Windows 98 to help users reclaim disk space, featuring commands that allow saving cleanup profiles, a functionality that persists in Windows 11. Task Scheduler, introduced in 1995 as System Agent in the Microsoft Plus! pack for Windows 95, automates tasks based on specific triggers. System File Checker (SFC), dating back to Windows 98, scans and repairs protected Windows resources, evolving from a graphical utility to a command-line tool. Device Manager provides an expandable tree of hardware components and reflects advancements in Microsoft's Plug and Play system from Windows 95, continuing to assist users in hardware inspection and troubleshooting. The DirectX Diagnostic Tool (DxDiag) was created for gamers in the late '90s to examine hardware and software configurations related to DirectX and remains available in Windows 11.

Windows 11’s driver signature requirement is one of the best anti-consumer security features out there

Windows 11 requires drivers to be digitally signed, a policy aimed at enhancing security by preventing unauthorized code from executing at the kernel level. This requirement, which began with Windows Vista and became mandatory with Windows 10, version 1607, has tightened over the years, especially with the introduction of UEFI Secure Boot and TPM in Windows 11. While this enforcement protects against malware and supports anti-cheat systems in gaming, it limits user autonomy and imposes significant challenges for developers, particularly those working on smaller projects. In contrast, Linux allows users more freedom to modify their systems, though this flexibility can compromise security.

These 4 built-in Windows tools helped me build a self-healing PC

Windows operating systems include built-in tools for maintaining PCs, allowing users to monitor system health, repair corrupted files, and recover from boot failures with minimal intervention. Task Scheduler automates maintenance tasks by triggering them based on schedules or events, accessible via the Start menu or taskschd.msc. It can activate tasks at fixed intervals, on startup, during idle periods, or in response to Event Viewer entries. Tasks should run with the highest privileges and can be configured to execute regardless of user sign-in status. The Settings tab allows missed tasks to run as soon as possible. DISM (Deployment Image Servicing and Management) is a command-line utility that repairs the component store, essential for installing updates and restoring system files. It offers three inspection levels: CheckHealth, ScanHealth, and RestoreHealth, with the latter requiring an internet connection for downloading replacement files. DISM logs operations in C:WindowsLogsDISMdism.log. SFC (System File Checker) verifies and repairs core operating system files using Windows Resource Protection. The command sfc /scannow checks all protected files, while /verifyonly provides a report without changes. SFC's effectiveness depends on the integrity of the component store, making it essential to run DISM first. Results are logged in C:WindowsLogsCBSCBS.log. Quick Machine Recovery (QMR), introduced in Windows 11, addresses boot failures by connecting to the internet to find solutions when repeated boot failures are detected. QMR is enabled by default on unmanaged devices and can continuously check for fixes. It is designed to respond to widespread issues rather than unique problems and may not work effectively on older hardware or without a network connection. Together, these tools provide a comprehensive approach to system maintenance in Windows 11, ensuring the operating system remains healthy and efficient without additional software.

Why Does Windows Explorer Use So Much Memory?

A user on Reddit reported that Windows Explorer was using over 21GB of memory, which can cause performance issues on systems with less than 8GB of RAM. One cause of excessive memory consumption is third-party shell extensions, which can be identified by booting into Safe Mode. A tool called ShellExView can help locate problematic extensions. To create a system restore point, users can press Win + R, type systempropertiesprotection.exe, click Create, enter a description, and click Create. Windows Explorer may also retain large caches of temporary data, leading to high memory usage. To clear temporary files, users can press Win + I, navigate to System > Storage > Temporary files, check the relevant boxes, and click Remove files. They can also manually clean the thumbnail and icon cache by deleting specific files in the %localappdata% directory. Corrupted system files can contribute to high memory usage, and users can run DISM and SFC tools to repair these files by accessing the Terminal (admin) and executing the commands DISM.exe /Online /Cleanup-image /Restorehealth and sfc /scannow.

Here’s What Actually Happens When Antivirus Software Scans Your PC

Interactions with antivirus software occur during installation and when issues arise, while the software operates quietly in the background. Modern antivirus solutions continuously monitor for threats using various detection methods, including real-time scanning, which actively scrutinizes files as they are downloaded or accessed. The signature database is essential for identifying malware by comparing files against known signatures, but it can only detect documented threats. Heuristic detection and behavioral analysis help catch unknown malware by evaluating suspicious characteristics and monitoring file actions during execution. Sandboxing allows suspicious files to run in a controlled environment, logging their behavior to determine if they are malicious. Quarantine neutralizes threats by locking files in a secure location, allowing users to review them before deletion. Full scans are resource-intensive and can slow down system performance, while real-time scanning is less demanding. Users can schedule scans during idle times, exclude trusted folders, or consider cloud-based solutions to mitigate performance impacts.

How to Free Up Disk Space on Windows 11

Your C: drive may be full, causing Windows to send reminders about low disk space or updates failing to install. Windows 11 includes built-in tools to help reclaim disk space. The guide outlines methods for recovering space, starting with the quickest techniques. 1. Cleanup Recommendations: Navigate to Start > Settings > System > Storage > Cleanup recommendations to review and remove temporary files, large or unused files, and apps. Deleting the previous Windows installation can recover several gigabytes but is irreversible. 2. Clear Temporary Files Manually: Go to Start > Settings > System > Storage > Temporary files to manually select and remove temporary files. 3. Empty the Recycle Bin: Right-click the Recycle Bin and select Empty Recycle Bin to reclaim space from deleted files. 4. Find and Move Large Personal Files: Use File Explorer to locate and move large files from Videos, Music, Pictures, or Downloads to an external drive. 5. Uninstall Unused Apps: Uninstall applications via Start > Settings > Apps > Installed apps, the Start menu, or Control Panel. 6. Turn On Storage Sense: Activate Storage Sense in Start > Settings > System > Storage to automate cleanups. 7. Configure Storage Sense Schedule: Adjust the schedule for Storage Sense cleanups in Start > Settings > System > Storage > Storage Sense. 8. Use Classic Disk Cleanup: Access the classic Disk Cleanup tool by typing "disk cleanup" in the search box to remove system files and items overlooked by the Settings scan. 9. Free Up Local Space with OneDrive Files On-Demand: Enable Files On-Demand in OneDrive settings to keep files in the cloud and free up local space. 10. Redirect Where New Content Is Saved: Change the default save location for new files in Start > Settings > System > Storage > Advanced storage settings. 11. Use External Storage to Install a Stuck Update: Connect an external USB drive with at least 10 GB of free space to assist with installing updates. 12. Rule Out Malware: Run a Windows Security antivirus scan if disk space continues to disappear unexpectedly. Deleting files in File Explorer moves them to the Recycle Bin, and space is not reclaimed until it is emptied. Deleting the previous Windows installation is irreversible and can only be done within 10 days of an upgrade. The KB5074105 update changed the scan context for Temporary files, preventing certain admin-restricted items from being detected. Storage Sense operates only on the system drive and does not automatically delete files in Downloads or OneDrive unless configured.
