How to Reset Registry to Default in Windows 11

Many applications modify the Windows 11 registry without user awareness, potentially leading to issues such as boot problems, application crashes, and settings reverting unexpectedly. Windows 11 does not have a "Reset Registry to Default" button, but there are methods to restore the registry to a functional state. Common indicators of registry issues include: - Applications crashing or failing to open. - Blue Screen of Death errors after registry edits or software installations. - Prolonged boot times. - Settings not saving or reverting unexpectedly. - Error messages about missing DLL files or broken file associations. - USB devices or peripherals not being recognized. To address registry issues, users can try the following methods: 1. System Restore: This method restores system-level changes without erasing personal files, provided a restore point exists. 2. Reset Windows 11: This reinstalls the operating system and resets the registry, with options to keep personal files or remove everything. 3. Import a Registry Backup File: This method restores specific registry keys if a backup exists. 4. Offline Registry Repair via Command Prompt: This is an advanced method for unbootable systems, involving manual replacement of registry hive files. Users are advised to back up the registry before making changes and to avoid using registry cleaners, as they can cause more harm than good. Regularly creating restore points and being cautious with online advice can help prevent registry problems.

Microsoft confirms that a stack of bad Windows updates is causing boot issues

Windows 11 is facing significant issues following the January Patch Tuesday, particularly with boot failures on commercial devices. These problems are linked to both the January update and a flawed December update, leading to a "UNMOUNTABLEBOOTVOLUME" Blue Screen of Death (BSOD) error. Microsoft has indicated that devices that did not successfully install the December security update are left in an improper state, which can prevent booting when subsequent updates are attempted. While Microsoft is working on a partial solution to prevent further installations that could cause boot failures, this fix will not resolve issues for devices already affected. The company is investigating the causes of these update failures and their consequences.

Your BitLocker-secured Windows PC isn’t so secure after all – unless you do this

Microsoft's BitLocker encrypts personal files on Windows hard drives to protect against unauthorized access in case of loss or theft. The BitLocker recovery key is essential for decrypting data, but Microsoft has confirmed it will comply with valid legal requests for access to these keys if they are stored in the cloud. This was highlighted during an FBI investigation in Guam, where Microsoft provided recovery keys related to a COVID unemployment fraud case. Microsoft receives about 20 requests for BitLocker keys annually, but many cannot be fulfilled if users do not store their keys in the cloud. The Guam case is the first known instance of Microsoft providing encryption keys to law enforcement, contrasting with a previous request from the FBI in 2013 that was declined. Users can choose to store their keys locally or in Microsoft's cloud, but storing them in the cloud carries risks of unauthorized access. For optimal security, it is recommended to save the recovery key on a USB stick or external drive, encrypting the file if necessary, and avoiding cloud storage. Users should check their BitLocker settings in Windows 11 or 10 to manage their recovery keys and consider removing any keys stored in the cloud.

Microsoft’s first Windows 11 update of 2026 has been a mess

Microsoft has issued two emergency fixes for issues arising from its January 2026 update for Windows 11. The first patch aimed to resolve various problems but resulted in shutdown issues for certain machines, particularly those using the Enterprise and IoT editions of Windows 11 version 23H2. In response, Microsoft released an out-of-band update to fix these shutdown problems. A week later, another out-of-band update was required to address crashes in OneDrive and Dropbox for users on Windows 11 versions 24H2 and 25H2. Additionally, Microsoft is investigating reports of boot failures linked to the January update, with some machines experiencing bluescreen errors and requiring manual recovery. This situation mirrors a previous incident where a security update was initially blamed for SSD issues, which were later attributed to firmware and motherboard BIOS problems.
