[45] On machines using a Computer-AT real-time clock, by default the hardware clock still must be set to nearby time for compatibility with BIOS-dependent Home windows,[four] unless applying current versions and an entry from the Windows registry is set to indicate the use of UTC.
If You aren't really interested in the security brought by Secure Boot and therefore are only enabling it to satisfy the requirements posed by Windows 11, you may want to consider disabling the validation procedure in shim with mokutil --disable-validation.
Just by including Spring boot stability dependencies to the class path, usage of the applying is secured with one hurdle.
UEFI machines might have amongst the next lessons, which ended up accustomed to assist ease the transition to UEFI:[eighty five]
I've built several makes an attempt at this, employing the various instructions and arguments within the outlined internet sites.

the primary two implement to my condition much better, simply because I want click here to help keep the Microsoft signatures installed, but Rod Smith's site is really a wealth of data.
Warning: changing the platform keys with your have can wind up bricking hardware on some machines, including laptops, rendering it not possible to have in the firmware settings to rectify the problem.
