====== Resetting Trusted Platform Module (TPM) ======
===== Prerequisites =====
  - UEFI install of Windows \\ How to check
    - Run **msinfo32**
    - Look for entry called "BIOS Mode". Should be a 14th line from the top. \\ {{:laptopwiki:guides:tweaking:msinfo_biosmode.png?400|}}
  - If you don't see "BIOS Mode  UEFI" you will need to reinstall using UEFI mode. If you do have UEFI mode, continue below.

<WRAP WARNING> Warning: if you have bitlocker enabled, you need to disable it before proceeding, unless you like losing all your data. if you don't know what bitlocker is, you don't have it. </WRAP>

===== Resetting =====
  - Press Win+R to open the Windows Run dialog
  - Type **tpm.msc** and press Enter
  - If this opens normally, you should be able to clear the TPM and reboot and be done. It's not uncommon to get an error here if you have this problem.
  - If that didn't work do the following:
    - Open the start menu and type **Device Security**
    - Select **Security Processor Details** -> **Security Processor Troubleshooting** and select **Clear TPM**
    - You'll be prompted to restart, so restart your machine
    - After the restart it should be working correctly.
