Basic Info :
OEM (Certificate & Key) install only where bios already (or modded) contains slic 2.1
Add slic 2.1 to Bootloader (0.97 grldr customised by Zsmin for me) with option (Default,Alternative, Low Memory, Debug, Forceful)
- default option allows auto-detect best method where possible
- alt method relocates SLIC, RSDT, XSDT and RSD PTR to low memory
- low memory method relocates SLIC to low memory
- forceful mode tries to activate on systems where some checks don't complete successfully, may cause problems.
- Debug mode allows view to process behind bootloader.
Install GUID Path (Thanks to PAYMYRENT) failing which install using Mount method.
Add Security to bootloader (Read Access only).
Randomly renamed grubloader (Thanks to PAYMYRENT) failing which allow its user to try normal grldr.
Add slic 2.1 to Bootmgr (No grldr means less time to boot, not recommended).
Certificate install where you want to replace certificate only.
Key install where you want to replace key only.
OEM Slic detection with matching OEM Key if possible. (You can always choose different OEM Key available or own custom key)
Check incorrect custom key.
Detects SLIC version(Thanks to MasterDisaster) and then autoselect best activation mode.
Detects BIOS Mod, any loader or if no loader installed in most cases.
Option to add custom slic and certificate.

Advantage :
Fast Install (since based on WMI script).
Single file.
Much smaller in size (since based on .NET Framework 2.0).
Bootloader are randomly renamed and so uninstall of old ldr not necessary.
Slic can be added in bootmgr (Not recommended).
Cert & Slic option are together for OEM install.
Cert can be installed/replaced only.
Key can be replaced only.
Option to add your customised OEM info and logo.
Option to backup and restore your licence (useful for retail and mak key users).
Option to dump slic matching OEM certificate.
Default start autoselect best activation mode, slic, cert and key.
Detects BIOS Mod, any loader or if no loader installed in most cases from MBR of disk.
Option to add CUSTOM certificate & slic for bootloader or certificate only for bios mod includes validating MATCH.
