My Recovery key bitlocker failed unlocking

Hi.

Earlier this year i had a problem with my computer where it would not scan for virus by the integrated windows security. It simply said ''you do not have administration access'' or something like that. I used this thread and tried many things, but i could not resolve it. Then i took my computer to an IT guy who works at a professional shop and solved it by doing a clean install. he said that probably my lenovo computers updates did'nt co-respond with the new windows updates. he clean installed it to an earlier windows 11 update and said i shouldnt update it until a little while.

after this i have only used the computer for school assignment, and left it alone.

the school year has now started, and now the new updates has been installed.

the problem is that the Service host: diagnostic policy... is sky hi in the task manager. the CPU is around 30% and the memory is around 388 MB, earlier before the update the memory had a couple thousands MB.

so i took a Full scan, no viruses. then i wanted a deep offline scan. but when i take the offline scan it wants a recovery key through bitlocker. first i skiped it, but i just took me back to deskop. then i found my key, and entered it, but it simply said unlocking fail or something with yellow writing.

What should i do? and what is the problem?

Regards

Alex

    Hello Alex T7,

    thank you for posting on the Microsoft Community Forums.

    If your BitLocker recovery key is failed to unlock, there might be an underlying issue with BitLocker or the TPM (Trusted Platform Module).

    1. Verify Recovery Key: Double-check the BitLocker recovery key you have. Make sure it's the correct one for the drive in question.
    2. Suspend and Resume BitLocker: Open Command Prompt as an administrator, and then run the following commands: manage-bde -protectors -disable C: manage-bde -protectors -enable C: replace "C:" with the appropriate drive letter.
    3. BitLocker Repair Tool: Open Command Prompt as an administrator, and then run the following commands:

    repair-bde C: X: -rp [your BitLocker recovery key]

    "C:" is the BitLocker drive and "X:" is a separate, empty drive where you can move the data. Ensure you have another drive that can take the data, as this command attempts to recover the data to another location.

    Hope it helps.

    Kind regards,

    Lei
