Bitku Je to a funkcia introdus gratuit de Microsoft na operačných systémoch Windows Vista, Windows 7 Konečný a Windows 7 Enterprise, pentru a proteja datele de pe pevný. Cu ajutorul BitLocker avem posibilitatea de a cripta (encryp hdd drive) atat partitia de sistem cat si partiile de date ale hard-disk-ului, insa pentru a face acest lucru avem nevoie de Trusted Platform Module (TPM). Nu toate calculatoarele / laptop-urile au acest Tpm intergrat, iar atunci cand dorim sa activam BitLocker pentru o partitie, ne apare mesajul :
A compatible Trusted Platform Module (TPM) Security Device must be present on this computer, but a TPM was not found. Please contact your system administrator to enable BitLocker.
Cum putem folosi BitLocker daca nu avem Trusted Platform Module (TPM).
1. Deschidem Local Group Policy Editor. (run – Gedit.msc sau tastam “Gedit.msc” in Search programs and files (Start Menu))
2. In Local Policy Group mergem la Konfigurácia počítača > Administratívne šablóny > Komponenty systému Windows > Bit Locker Drive Encryption > Operating System Drives si facem click-dreapta & Edit (sau dublu-click) pe Require additional authentication at startup.
3. Bifam “Umožniť” in fata la Require additional authentication at startup si ne asiguram ca este bifata si casuta de la Allow BitLocker without a compatible TPM.
4. Uplatňovať & V poriadku & Restart computer.
