Some drawbacks of turning on TPM in Windows 11 include performance impacts and compatibility issues.
Some drawbacks of turning on TPM in Windows 11 include performance impacts and compatibility issues.
I've been hoping for some calm before making the change. Upgrading to Windows 11 required enabling TPM, which raised my worries about possible downsides. In theory, TPM should block HDD swaps to protect data, but as a developer I often switch drivers, so I’m cautious. Right now I don’t use BitLocker and won’t in the future; I swap drives for flexibility, not because privacy isn’t important. I don’t want my recovery keys tied to a TPM or tracked during recovery.
When upgrading, I’m concerned someone might help if issues arise. In theory, if BitLocker is disabled, TPM should remain inactive—shouldn’t that be fine? I’m not sure. A user reported BitLocker automatically enabled and encrypted his drive during the upgrade, noting he didn’t see a prompt to save the recovery key.
Could this happen? If so, what fixes exist to disable BitLocker after upgrading? I’ve got external drives with BitLocker set up without TPM, and my keys are saved. If I connect one to a Windows 11 PC with TPM enabled, will it behave differently? I’m not sure, but I want to be sure before proceeding.
Feel free to ask if any of these points seem off or if you have more details to share. I tried to look into this myself, but the info online is mixed.
Before proceeding, it’s important to confirm your motherboard has the most recent UEFI version. Please adhere to the guidelines provided in your manual for a seamless transition to Windows 11. This helps avoid problems with features you enable that were initially disabled and later found problematic. When Windows 11 launched, several manufacturers released updates to address reported issues. TPM ensures drive security without locking them permanently; you can manage them as needed. Bit-Locker secures drives by locking them to the system, allowing swaps but only on the original device. If recovery is lost and the system isn’t bootable, Windows will initiate a recovery process requiring the key. If linked to Microsoft, the key is stored automatically and accessible via their portal. Without it, you’ll need to back up your drive manually. Remember, by default Bit-Locker is disabled. If you’ve previously enabled it, you won’t see the prompt. Windows 11 demands TPM for enhanced protection; disabling it may cause installation failures. Keep the recovery key handy—online advice can be misleading.
