Why I stopped using ‘Modern Standby’ on my Windows laptop to save battery overnight

Many newer PCs support a feature called Modern Standby, which allows minimal background processes to continue running during sleep mode, leading to quicker wake-up times but potentially less efficient battery preservation. PCs can operate in one of six states, with S0 indicating full operation and S5 indicating a complete shutdown. Modern Standby (S0 Low Power Idle) turns off the display and most core components while allowing limited background activity, which may vary in effectiveness for battery drain. Traditional Sleep (S3) shuts down the screen and main components but may take longer to resume. Hibernate (S4) saves the current session and powers off completely, while Restart clears memory and resets the operating system. Shut Down (S5) clears memory and terminates processes, using a "soft off" method that retains certain settings for quicker startups through fast boot. Disabling fast boot can be done via the Control Panel. Although Modern Standby can conserve battery, it may not always be effective, as issues with firmware or drivers can prevent the computer from entering a true low-power state. For maximum battery efficiency, using the Shut Down option is recommended, especially with fast boot enabled for quick startups.

Microsoft releases Windows 10 KB5078885 extended security update

Microsoft has released the Windows 10 KB5078885 extended security update, which addresses vulnerabilities identified during the March 2026 Patch Tuesday. This update resolves two zero-day vulnerabilities and a critical issue preventing certain devices from shutting down properly. Users of Windows 10 Enterprise LTSC or those in the ESU program can install it via Settings under Windows Update. The update upgrades Windows 10 to build 19045.7058 and Windows 10 Enterprise LTSC 2021 to build 19044.7058. The update focuses on security enhancements and bug fixes, addressing a total of 79 vulnerabilities, including two actively exploited ones. Key fixes include: - A new warning dialog in Windows System Image Manager for confirming trusted catalog files. - Enhancements to File History for backing up files with specific Chinese and Private Use Area characters. - Stability improvements for specific GPU configurations. - Additional high-confidence device targeting data for Secure Boot certificates. - Adjustments to Chinese fonts for compliance with GB18030-2022A standards. - A fix for Secure Launch-capable PCs with Virtual Secure Mode unable to shut down or hibernate after a previous security update. - Resolution of an issue affecting folder renaming with desktop.ini files in File Explorer. The update also addresses a known issue preventing Windows 10 devices from shutting down or hibernating when System Guard Secure Launch is enabled. Microsoft is deploying new Secure Boot certificates to replace those expiring in June 2026, which are crucial for validating boot components and preventing security risks. There are currently no known issues associated with this update.

Microsoft issues SECOND emergency out of band update for Windows 11 to address disastrous Patch Tuesday bugs

Microsoft's January 2026 Patch Tuesday updates for Windows 11 have caused significant user frustration, leading to two emergency out-of-band updates within a week to address critical issues. The latest emergency update, KB5078127, was released to fix problems that made applications like Outlook, OneDrive, and Dropbox inoperable after the January 13 updates. Initially, users were advised to uninstall the updates as a temporary fix. The first emergency update on January 17 aimed to resolve shutdown and hibernation failures for version 23H2 and issues with Remote Desktop sign-in, but it inadvertently caused further disruptions to essential applications. The Windows release health dashboard remains a key resource for users seeking updates on ongoing issues.

Windows 11 PCs Fail To Shut Down After Update

Some users of Windows 11 have experienced a problem where their PCs reboot instead of shutting down after the Patch Tuesday security update KB5073455. This issue primarily affects devices with Secure Launch on Windows 11 version 23H2. Microsoft has confirmed this behavior, which disrupts the usual power-off sequence and can drain battery life for laptops and complicate remote management processes. An out-of-band update, KB5077797, has been released to restore normal shutdown and hibernation functionalities for affected systems. Users can check for this update in Windows Update or download it from the Microsoft Update Catalog. To determine if they are affected, users should look for immediate restarts when selecting Shut Down or Hibernate and check if Secure Launch is enabled in System Information.

Windows 11 shutdown bug: Microsoft confirms KB5073455 issue

Microsoft has acknowledged a shutdown issue affecting Windows 11 Enterprise and IoT editions after the January 13, 2026 security update (KB5073455) for version 23H2, which prevents affected systems from shutting down properly, causing them to either hibernate or restart instead. The problem is linked to the System Guard Secure Launch feature and does not affect Windows 11 Home and Pro editions. A temporary workaround involves using the command "shutdown /s /t 0" in an elevated Command Prompt to force a shutdown, but there is no workaround for hibernation functionality. Microsoft is working on a resolution and suggests that enterprise IT administrators consider pausing the deployment of the update on unaffected devices.

Sorry Dave, I’m afraid I can’t do that! PCs refuse to shutdown after Microsoft patch

Microsoft's January Patch Tuesday update has caused shutdown and hibernation issues for some Windows 11 23H2 users, with devices refusing to power down despite user commands. The problem is linked to the Secure Launch feature, which prevents shutdown, restart, and hibernation attempts from functioning correctly. Microsoft has suggested a workaround using the command "shutdown /s /t 0" to force shutdown. They have not disclosed how many devices are affected or provided a timeline for a fix. Additionally, there is a separate issue affecting classic Outlook POP account profiles that may freeze or hang after the update.

‘Fail To Shut Down’—Microsoft Issues Windows Update Warning

Microsoft has raised concerns about the shutdown process of Windows PCs, indicating complications following the January 13, 2026, security update. PCs with Secure Launch may fail to shut down or hibernate, instead restarting unexpectedly. A temporary solution is to use the Command Prompt with the command shutdown /s /t 0 for shutting down, but there is no workaround for the hibernation issue. Microsoft recommends saving work and shutting down devices to avoid power loss. Additionally, some users are facing credential prompt failures during Remote Desktop connections, affecting services like Azure Virtual Desktop and Windows 365. Alternatives include using the Remote Desktop client for Windows or the Windows App Web Client. An emergency update is expected to resolve these issues.

How to speed up mass data inserts in PostgreSQL when using Spring

A common task in enterprise systems involves loading large volumes of data into PostgreSQL, which can be slow if using a loop in Java that calls the save() method for each record. Initial tests show that a basic insert operation takes over 10 minutes. Hibernate retains every object in the session-level cache until the transaction concludes, leading to high memory consumption. Enabling batching with the jdbc.batch_size setting improves performance by about 23%, but high memory usage persists. Application-side caching of IDs is faster than database-side caching, achieving a 30% performance gain. Using saveAll() results in minimal improvement as it still calls save() in a loop. Enabling reWriteBatchedInserts in the JDBC driver allows for multi-row inserts, reducing operation time to 4 minutes and 37 seconds. Clearing the session-level cache with EntityManager further optimizes memory usage, resulting in an 18-second time gain. Setting order_inserts=true enhances batching efficiency. With all optimizations, insertion time is reduced to 4 minutes and 19 seconds. A custom data insertion layer can be created to generate INSERT statements, with reflection being a straightforward but not optimal method. Prepared statements improve performance and security, with an efficient batch size of 5,000 records. PostgreSQL's COPY command facilitates faster bulk data transfers than multi-row inserts. Integrating COPY with Spring transactions enhances performance, and parallelizing the insertion process with a ThreadPoolExecutor significantly improves speed and memory usage.
