    My colleague is working on some second-hand but fairly new Dell computers T5600 and noticed that some are booting up very fast and others seem to be waiting for about 2.5 minutes before they go into Bios for bootup. He discovered TPM and disabling this will mean the pc will boot up without this delay.
    I read up on the general purpose of TPM and realise that for Win 11 it will be necessary and bitlocker is using this. If we do not use bitlocker at this stage and are still on Win 10, are there any reasons to leave this enabled and accept the delayed boot up time?

    Interesting observation. Thanks.

    My two desktops have had TPM disabled until a few weeks ago (Win11). I haven't noticed any boot time difference.

    TPM was already enabled on my desktop PC. I haven't noticed any slowdown. Compared to my MBR laptop without TPM I'd say it boots quicker.

    Interesting article - I was checking my own pc (HP) but it is not supported, so checking on mine did not lead anywhere. I am a bit concerned that the two minute delay my friend is reporting and which apparently can be avoided on the pc he is installing by disabling this feature is not a commonly reported. Makes me wonder why his pc has this issue.

    I just know that tpm will make private key operation at startup and this can take half second for each key cause tpm is a slow device, so maybe your friend got multiple keys installed

    I don't think multiple keys would be the issue and doubt he would notice a few seconds in boot time but plan1098 seems to indicate that he experienced the same delay until he disabled a specific intel service which is interesting. I will pass on that info.
