    I want to install the regular August update KB5012170. I am Paralles18 not 17. I have completed the September regular update but it still will not install.
    Is there any way I can update it?

    I have successfully installed KB5012170 on Parallels 17.1.4 (51567). I ran this link based on post on the topic.
    But in my case, I could not succeed in that way.
    1. Shutdown VM.
    2. Open VM's setting.
    3. Remove the TPM on the Hardware.
    4. Edit config.pvs in VM.pvm in Finder.
    5. Set the value of EfiSecureBoot to 0(zero).
    6. Go back to Parallels vm's settings (Hardware) and select "Boot Order". *This is where the process differs from his post.
    7. Click "Details..." button and change back to "vm.efi.secureboot=0". *This is where the process differs from his post.
    8. Start VM.
    9. Start Windows Update.
    10. I succeeded.
    11. Shutdown Windows.
    12. Go back to Parallels vm's settings (Hardware). Add TPM. Set 'vm.efi.secureboot=1' in the BOOT ORDER.
    13. Reset the value of EfiSecureBoot in config.pvs to 1.
    14. Start Windows.
    I've heard that deleting TPM can cause data loss, but in my case I don't seem to have lost anything in particular.
