Windows 11 version 24H2 has faced significant criticism due to security and reliability issues, with users reporting numerous critical bugs. Compatibility problems have been noted with cache-less WD SSDs, Ubisoft games, Asus devices, fingerprint sensors, USB scanners, and devices using the eSCL scan protocol. Microsoft has confirmed that after upgrading to 24H2, USB devices supporting eSCL may become undetectable, disrupting communication with networked scanners, printers, fax machines, modems, and other devices reliant on this protocol. Since the rollout on October 1, 2024, users have reported that their eSCL-compatible devices are inoperative in various environments. Businesses are urging Microsoft for a fix, and the company is working on a solution but has not provided a timeline. To address these issues, Microsoft has placed a "compatibility hold" on PCs connected to eSCL devices, preventing automatic upgrades to 24H2, and has advised users to avoid manual installation of the update until resolved.
