Microsoft is investigating a bug triggering safety alerts on techniques with a Trusted Platform Module (TPM) processor after enabling BitLocker.
BitLocker is a Home windows safety function that encrypts storage drives to forestall knowledge theft or publicity. Based on Redmond, it “provides maximum protection” when used with a TPM “to ensure that a device hasn’t been tampered with while the system is offline.”
TPMs are devoted safety processors that present hardware-based safety features and act as trusted {hardware} elements for storing delicate knowledge, akin to encryption keys and numerous different safety credentials.
In an advisory printed Tuesday, the corporate says this recognized situation additionally impacts unmanaged gadgets, often known as BYOD (brief for bring-your-own-device). These are normally personally owned gadgets utilized in enterprise environments that may be onboarded or secured utilizing measures offered by every group’s IT or safety staff.
On affected Home windows 10 and 11 PCs, customers will see a “For your security, some settings are managed by your administrator” alert “in the BitLocker control panel and some other places in Windows.”
Microsoft says it is presently engaged on a repair and can present extra particulars in regards to the situation when it has extra info.
In April 2024, Microsoft mounted one other situation that triggered incorrect BitLocker drive encryption errors in some managed Home windows environments. The corporate tagged this situation in October 2023 as a reporting downside that didn’t impression drive encryption.
Months later, in August, Redmond addressed one other bug inflicting some Home windows gadgets in addition into BitLocker restoration after putting in the Home windows safety updates.
The identical month, it disabled a repair for a BitLocker safety function bypass vulnerability (CVE-2024-38058) attributable to firmware incompatibility points that brought about patched Home windows gadgets to enter BitLocker restoration mode.
Microsoft introduced in June 2021 that TPM 2.0 is a obligatory requirement for putting in or upgrading to Home windows 11, saying it will make techniques extra immune to tampering and complicated cyberattacks. Nonetheless, this hasn’t stopped Home windows customers from creating numerous instruments, scripts, and methods to bypass it.
Greater than three years later, in December 2024, Redmond made it abundantly clear that TPM 2.0 help is a “non-negotiable” requirement, as clients will not be capable to improve to Home windows 11 with out it.
Statcounter International knowledge presently reveals that over 62% of all Home windows techniques worldwide nonetheless run Home windows 10, whereas lower than 34% run Home windows 11 three years after its October 2021 launch.
