System Compatibility Check

System Requirements

Anti-Winver checks these requirements on every launch. Click any item to open its setup guide.

Recommended Security Configuration

Windows 10 (22H2) or Windows 11 (21H2–24H2+)

Build 19045+ (Win 10) or Build 22000+ / 26100+ (Win 11) required

Secure Boot

Must be OFF in BIOS before setup — managed automatically once active

TPM 2.0

Trusted Platform Module must be active

DSD — System Compatibility Layer

Configured automatically during Anti-OS setup

EFI-B — Anti-OS Pre-Loader

Anti-OS pre-loader must be active on this system

Anti-OS — Core Service Active

System service must be loaded and running

Windows Drive Space

Minimum 50 MB free on system drive required

01   Windows 10 & 11

Windows 10 (22H2) or Windows 11 (21H2–24H2+)

Anti-Winver supports Windows 10 Build 19045 (22H2) and Windows 11 Builds 22000 through 26100+ (24H2). Earlier builds lack the system architecture required for module initialization and identity virtualisation.

STEP 01 — CHECK YOUR CURRENT BUILD

  1. 1. Press Windows Key + R
  2. 2. Type winver and press Enter
  3. 3. Confirm Build 19045+ (Windows 10) or Build 22000+ / 26100+ (Windows 11)
PASSBuild 19045+ or 22000+ — you're good
UPDATEAnything below — upgrade required

STEP 02 — UPGRADE TO WINDOWS 11 24H2

A.

Windows Update (easiest)

Settings → Windows Update → Check for Updates

B.

Clean install via ISO

Download the official ISO from Microsoft and perform a clean installation.

02   Secure Boot

Secure Boot Configuration

Anti-Winver's check is state-aware. The green/red status means different things depending on whether Anti-OS is active:

EFI-B ACTIVE

Anti-OS pre-loader is active. Secure Boot is emulated by the system layer — green means it is operating correctly. No action needed.

PRE-INSTALL

Anti-OS not yet active. Secure Boot must be physically OFF in BIOS before setup. Green = off (correct). Red = on (disable first).

STEP 01 — CHECK CURRENT STATE

  1. 1. Press Windows Key + R, type msinfo32, press Enter
  2. 2. Check BIOS Mode (must say UEFI) and Secure Boot State

STEP 02 — DISABLE SECURE BOOT IN BIOS (PRE-INSTALL)

Restart and enter BIOS (Del / F2 / F10). Or from Windows:

Settings → System → Recovery → Advanced startup → Restart now
→ Troubleshoot → Advanced options → UEFI Firmware Settings

Find Secure Boot under Boot or Security tab → set to Disabled. Save with F10.

⚠ Legacy BIOS Users

If BIOS Mode shows LEGACY, convert your drive from MBR → GPT first using mbr2gpt /convert /allowFullOS, then switch BIOS mode to UEFI. Skipping this will prevent Windows from booting.

03   TPM 2.0

Trusted Platform Module 2.0

TPM 2.0 is required by Windows 11 and used by Anti-Winver during its session checks. It must be present, active, and version 2.0.

STEP 01 — CHECK TPM STATUS

  1. 1. Press Windows Key + R, type tpm.msc, press Enter
  2. 2. Check the status message and Specification Version
PASS"The TPM is ready for use" + Specification Version: 2.0
ACTION"Compatible TPM cannot be found" — enable in BIOS
UPGRADEVersion 1.2 shown — update to TPM 2.0 in BIOS if available

STEP 02 — ENABLE TPM IN BIOS

Restart into BIOS, find TPM under Security or Advanced tab:

IntelSecurity → Intel PTT (Platform Trust Technology) → Enabled
AMDAdvanced → AMD fTPM Switch → AMD CPU fTPM

Save with F10. Rerun tpm.msc to confirm.

⚠ BitLocker Warning

If BitLocker is active, changing TPM settings may trigger a recovery key prompt. Suspend BitLocker first: Control Panel → BitLocker Drive Encryption → Suspend protection.

04   DSD

System Compatibility Layer

Windows requires all system components to meet specific compatibility requirements before they can operate. Anti-Winver's system layer ensures these requirements are met automatically during setup — no manual configuration needed.

How it works

During startup, the Anti-OS pre-loader configures system integrity settings before Windows initialises. This takes effect for the entire session without modifying any files on disk.

DSD IS RED — WHAT TO DO

DSD depends on the Anti-OS pre-loader being active and the system having been configured correctly on this boot. If DSD is red:

  1. 1. Check that EFI-B is green — if not, complete guide 05 first
  2. 2. If EFI-B is green but DSD is red — system configuration may not have applied. Reboot and check again
  3. 3. If the issue persists after a clean reboot — contact support with your Windows build number

⚠ Do not use test signing mode

Do not use bcdedit /set testsigning on as a workaround. It does not satisfy the compatibility requirements Anti-OS enforces and may be flagged by security software.

05   EFI-B

Anti-OS Pre-Loader

The Anti-OS pre-loader is the foundation of Anti-Winver. It initialises before Windows loads, ensuring the system is in the correct state for full identity virtualisation to operate. Without it, other components cannot activate.

STEP 01 — PREREQUISITES BEFORE INSTALL

✓Windows 10 (19045+) or Windows 11 (22000+ / 24H2)
✓Secure Boot OFF in BIOS
✓BIOS mode: UEFI (not Legacy/CSM)
✓TPM 2.0 active
✓50 MB+ free on Windows drive
✓Valid Anti-Winver licence

STEP 02 — INSTALL VIA THE MANAGER

  1. 1.Open Anti-Winver Manager as Administrator
  2. 2.Log in with your licence key
  3. 3.Navigate to the System Check tab — confirm Windows, TPM, and Secure Boot are green
  4. 4.Click Install Anti-OS — the Manager runs safety checks, securely backs up your existing configuration, then deploys the pre-loader
  5. 5.Reboot when prompted
  6. 6.After reboot, return to the Manager — EFI-B, DSD, and Anti-OS should all be green

⚠ Restore is always available

The Manager's Revert Profile function fully reinstates your original configuration from a verified backup baseline. The restore process is triple-verified before completing.

06   Anti-OS

Anti-OS Core Service Active

This check confirms the Anti-OS system component is loaded and active. It is responsible for hardware identity virtualisation in real time and only activates once all other requirements are satisfied.

ANTI-OS IS RED — DIAGNOSIS

CASE 1

EFI-B and DSD are also red

Anti-OS pre-loader is not active. Complete guide 05 (EFI-B) first — Anti-OS will activate automatically on the next boot.

CASE 2

EFI-B is green, DSD is green, Anti-OS is red

Pre-loader is active but the system component did not initialise. Most likely cause: a security scan intercepted the component file. Temporarily pause real-time protection, then use the Manager to re-deploy.

CASE 3

Service was active but session expired

Open the Manager and apply your profile from the main tab to re-activate the session.

07   Drive Space

Windows Drive Space

Anti-Winver requires at least 50 MB free on your Windows system drive (usually C:\) to deploy its components. The actual space used is small — this threshold is a safety margin. The Manager displays your exact free space next to this check.

DRIVE SPACE IS RED — FREE UP SPACE

A.

Disk Cleanup

Windows Key → type "Disk Cleanup" → select C: drive → check all boxes → OK
B.

Storage Sense

Settings → System → Storage → Cleanup recommendations → run all
C.

Temp files

Windows Key + R → %temp% → select all → delete

After freeing space, return to the Manager and click Refresh on the System Check tab.
