Advanced SystemCare 19 Cleaned 3GB Hidden Junk From My PC

The user experienced a slow computer with prolonged startup times and storage shortages despite manual cleanup efforts, including emptying the Recycle Bin and using Windows Disk Cleanup. A deeper system scan revealed hidden junk files such as temporary files, browser cache, and outdated logs. The user then utilized Advanced SystemCare 19 Free, which effectively identified and removed 3GB of junk files, resulting in improved startup speed, program launch times, and overall performance. Advanced SystemCare also includes features like a registry cleaner, large file finder, disk cleaner, and app/extension cleaner, and it serves as a comprehensive system optimization suite with tools for enhancing boot time and protecting privacy. The software does not delete files automatically and should be used alongside antivirus software for complete protection.

The 200GB catch hiding in Windows 11’s new recovery feature

Microsoft has introduced point-in-time restore for Windows 11 users, enhancing the traditional System Restore. This new recovery tool allows users to recover their PCs from software issues, problematic drivers, or faulty updates, even when Windows won’t boot. It uses the Volume Shadow Copy Service (VSS) to automatically generate restore points every 24 hours, which include both system and user files, unlike System Restore. Point-in-time restore manages storage by deleting restore points after 72 hours and integrates seamlessly into Windows Settings, being activated by default for volumes over 200GB. Users with smaller volumes must activate it manually. It also incorporates Reserved Storage to ensure restore points do not consume regular disk space. The feature is available on Windows 11 Home and Pro editions with the installation of the optional Preview Update KB5095093. Users can access point-in-time restore through Windows Settings under System > Recovery, and initiate recovery via the Windows Recovery Environment (Windows RE).

Windows 11 has more recovery options than ever, and here’s exactly when I would use each one to fix a broken PC

Microsoft has enhanced Windows 11 with various recovery tools that allow users to address system issues without needing to perform a complete reinstall. Key features include: - Reset This PC: Offers two options: "Keep my files" (reinstalls Windows while retaining personal files) and "Remove everything" (wipes the computer before reinstalling). Users can choose between a Local reinstall or Cloud download. - Cloud Rebuild: Accessible via the Windows Recovery Environment (WinRE), it reformats the OS partition, downloads a fresh Windows image, and restores the original setup without relying on local recovery images. - Go Back (Rollback): Allows users to revert to a previous installation after an upgrade if issues arise, utilizing the Windows.old folder, but is time-sensitive (files purged after about ten days). - Uninstall Updates: Enables users to remove recent updates that may cause problems without a full system reset. - System Restore: Creates restore points to revert to a stable state without affecting personal files. - Startup Repair: A tool in WinRE that scans for and fixes common startup issues. - Safe Mode: Starts Windows with essential drivers and services to troubleshoot problems. - Quick Machine Recovery: Automatically connects to Microsoft's recovery service to download fixes if Windows fails to start due to a faulty update or driver. - Point-in-Time Restore: Automatically reverts the system to a previous working state when updates fail. Other tools include the Windows Recovery Environment (WinRE), Recovery Drive for bootable USB access, Command Prompt, Startup Settings, and the Windows Backup app for restoring settings and files. The legacy Backup and Restore (Windows 7) tool is still available for creating backups and full system images.

Can Chromebooks Get Viruses? How to Protect Your Device

Chromebooks are designed with robust security features, including sandboxing, Verified Boot, automatic updates, data encryption, and Recovery Mode, which collectively reduce the risk of malware infections. However, they are still vulnerable to threats such as malicious Chrome extensions, scam Android apps from third-party stores, phishing attacks, and risks associated with using Developer Mode and cloud storage. Users can identify potential malware through signs like slow performance, unexpected pop-ups, and unusual battery drain. To remove malware, users should eliminate suspicious extensions, uninstall dubious apps, run antivirus scans, enable Google Play Protect, or perform a Powerwash to reset the device. To protect their Chromebooks, users should avoid Developer Mode, check app permissions, use two-factor authentication, verify website URLs, and use a VPN on public Wi-Fi.

Windows 95 didn’t detect installers, it ‘guessed’ based on the file name, says veteran dev — it simply checked for words like setup, install, inst, or localized equivalents

Raymond Chen, a Microsoft engineer, revealed that Windows 95 identified installation programs by analyzing executable filenames against a list of keywords, including "setup," "install," and "inst." The system would then initiate a routine to repair any compromised system files. The list included six terms: setup, install, inst, imposta, ayarla, and felrak. Chen noted redundancy in the list, suggesting "install" was unnecessary since it included "inst." For executables not matching the terms, Windows 95 scanned the executable's path for "Setup." The system maintained backup copies of frequently overwritten files in a hidden directory at C:WindowsSYSBCKUP and would restore correct versions after installers completed. File verification was often postponed until the next system boot, especially for installers that reverted to MS-DOS for file replacements. This file repair mechanism continues to influence modern operating systems, including Windows 11.

Microsoft Confirms Windows 11 Bug That Eats 500GB Of Your Storage

Microsoft has acknowledged a significant issue affecting Windows 11 users on versions 24H2 and 25H2, where a bug can consume up to 500GB of storage, leading to critical space shortages and potential system failure. This bug has been reported since May 2025, with a solution disclosed on June 29, but it will not be automatically rolled out until July 14. Users can check if they are affected by navigating to Settings > System > Storage and examining the “System files” category; if it exceeds 100GB, they are likely impacted. The issue is linked to a hidden file named CapabilityAccessManager.db-wal in the “%ProgramData%MicrosoftWindowsCapabilityAccessManager” directory. Microsoft has released an optional update (KB5095093) to address the bug, which also includes feature previews that may affect performance. Users are advised against deleting the problematic file to avoid disrupting WiFi connectivity and screen capture functionalities. An automatic fix will be deployed during the July 14 update.

Microsoft Confirms Windows 11 Bug That Can Consume Over 500GB of Storage Through Permission Log File

Microsoft has acknowledged a bug in Windows 11 that causes the Capability Access Manager's write-ahead log file to expand indefinitely, potentially exceeding 500GB of storage on affected devices. This issue is addressed in update KB5095093, which includes builds 26200.8737 and 26100.8737. Users can manually install this update via the optional updates section of Windows Update or wait for its automatic rollout during the July 2026 Patch Tuesday. The Capability Access Manager manages app permissions and logs usage of privacy-sensitive features, but the WAL file continues to grow unchecked on affected systems. The file can reach sizes from 70GB to over 513GB. To check if a system is affected, users can check storage settings or use Robocopy to verify the file size. The update is available through the Optional updates section and will be included in the cumulative update on July 8, 2026. The excessive size of the WAL file can lead to critical storage shortages and related issues, but it does not compromise the security or core functionality of the permission system. Microsoft has not confirmed if Windows 11 26H1 Insider builds are affected.

Microsoft admits a Windows 11 bug is eating up to 500GB of storage, verify if you are affected

To check for excessive storage consumption in Windows 11, navigate to Settings > Storage > System & Reserved. A file named CapabilityAccessManager.db-wal can cause significant storage issues, potentially consuming hundreds of gigabytes. This file is associated with the Windows Capability Access Manager service, which manages app permissions for features like microphone and camera access. Normally, this file should occupy only a few megabytes, but reports indicate it can expand to sizes like 200GB or even 513GB. Microsoft acknowledged this issue in the release notes for Windows 11 KB5095093, stating that an update to improve disk space usage for this file is scheduled for July 14, 2026. To check if your system is affected, tools like WizTree or TreeSize can be used, or a command can be executed in Command Prompt to verify the file size. If the file is excessively large, it is recommended to wait for the update or rename the file to allow Windows to regenerate it, rather than deleting it.
