FAT32 breaks free from its outdated limitation in latest Windows update

The FAT32 file system, historically limited to a 32GB partition size due to a design choice by Microsoft engineer Dave Plummer, can inherently support volumes up to 2TB with a 512-byte sector size and theoretically up to 16TB with 4KB sectors. While Windows maintained this 32GB limit, motherboard manufacturers had already developed firmware to utilize larger FAT32 drives. Tools like Rufus and GUIFormat were used to format high-capacity media, as Windows did not allow direct FAT32 formatting for drives larger than 32GB. However, with the introduction of Windows 11 Insider Preview Builds 26220.8165 and 26300.8170, users can now format large flash drives and external volumes as FAT32 directly from the Command Prompt without third-party software.

Connecting .NET Lambda to Amazon Aurora PostgreSQL via RDS Proxy

Many organizations are modernizing legacy .NET applications while reducing database costs and enhancing scalability, particularly during migrations to AWS Lambda and transitions from SQL Server to Amazon Aurora PostgreSQL-Compatible Edition. The process involves connecting Lambda functions to Aurora PostgreSQL using Amazon RDS Proxy, with AWS Secrets Manager managing secure credential storage. The architecture includes a .NET Lambda function interfacing with Aurora PostgreSQL via RDS Proxy, which provides connection pooling to minimize database connection overhead. The solution requires a CloudFormation template to provision resources such as a VPC with private subnets, an Aurora PostgreSQL cluster, RDS Proxy, and Secrets Manager. The RDS Proxy is configured with parameters including PostgreSQL engine family, idle client connection timeout, and Secrets Manager secret. A Windows EC2 instance is provisioned, and access is facilitated through AWS Systems Manager Fleet Manager. The solution includes creating a sample table named "employee" in the database and a new .NET Lambda project that utilizes Npgsql for database connections. The Lambda function is deployed using the AWS CLI, and testing involves invoking the function and retrieving logs from Amazon CloudWatch. Finally, resources created during the process should be deleted to prevent ongoing charges.

Windows 11 is finally removing the 32GB FAT32 capacity limit

Microsoft has released new test builds for Windows Insiders, specifically Dev Build 26300.8170 and Beta Build 26220.8165, which remove the 32GB limit on FAT32 formatting for external drives. Users can now format external drives up to 2TB using FAT32 through the Command Prompt. This change, which has been anticipated by users, is a shift from the long-standing restriction that required third-party applications or specialized commands for larger drives. The enhancement applies only to the Command Prompt, as the graphical interface remains unchanged, and the 4GB file size limit for individual files on FAT32 drives still applies. This feature is currently available only in preview versions for Windows Insiders, with a broader rollout planned for future standard Windows 11 updates.

How to Reset Folder Permissions in Windows 11: 5 Proven Methods That Actually Work

Folder permissions in Windows 11 control access to files, determining who can read, modify, or delete them. Common issues arise from drive or file migration, Windows updates, malware, or user errors. Symptoms include "Access Denied" messages and ownership displayed as "unknown." Methods to resolve folder permission issues include: 1. Security Tab: Reset permissions through the Security tab by modifying access levels and ensuring proper inheritance. 2. Take Ownership: Claim ownership of a folder if the current owner is no longer valid, then reset permissions. 3. Command Prompt: Use commands like PLACEHOLDERfa5c045a85bc6cf0 and PLACEHOLDER14a87b7576573f58 to reset permissions quickly and efficiently. 4. PowerShell: Utilize PowerShell for advanced permission resets, allowing for conditional logic. 5. Windows Reset: As a last resort, reset Windows to restore default permissions while keeping personal files. To prevent future issues, back up permissions before changes, understand NTFS vs. share permissions, and avoid altering system folders. If problems persist, ensure commands are run as an administrator, check ownership settings, and verify that Group Policy or sync tools are not overriding changes.
