“Access is denied” means Acronis Self‑Protection is blocking service control. Easiest fix: disable it from a minimal boot, then disable the Acronis services and reboot.
Do this exactly
Option 1 — Safe Mode (works regardless of Self‑Protection)
1) Restart → hold Shift while clicking Restart → Troubleshoot → Advanced options → Startup Settings → Restart → press 4 (Safe Mode).
2) In Safe Mode, open an elevated Command Prompt (Win+R → cmd → Ctrl+Shift+Enter), then run:
sc stop AcronisCyberProtectionService
sc stop ActiveProtectionService
sc stop AcrSch2Svc
sc stop afcdpsrv
sc stop tib_mounter_monitor
sc stop syncagentsrv
sc config AcronisCyberProtectionService start= disabled
sc config ActiveProtectionService start= disabled
sc config AcrSch2Svc start= disabled
sc config afcdpsrv start= disabled
sc config tib_mounter_monitor start= disabled
sc config syncagentsrv start= disabled
(If any name isn’t found, that service isn’t on your system—ignore.
3) Reboot normally and confirm Windows is responsive. You can re‑enable later with start= auto and sc start <name>.
Option 2 — If a service still refuses (flip it offline in WinRE)
1) Advanced startup → Troubleshoot → Advanced options → Command Prompt.
2) Find your Windows drive (dir C:\Windows or dir D:\Windows). Assume C: below.
3) Load the SYSTEM hive and set services to Disabled (Start=4):
reg load HKLM\OFFSYSTEM C:\Windows\System32\Config\SYSTEM
reg add "HKLM\OFFSYSTEM\CurrentControlSet\Services\AcronisCyberProtectionService" /v Start /t REG_DWORD /d 4 /f
reg add "HKLM\OFFSYSTEM\CurrentControlSet\Services\ActiveProtectionService" /v Start /t REG_DWORD /d 4 /f
reg unload HKLM\OFFSYSTEM
4) Continue to Windows; those services will not start.
Notes
- If you can open the Acronis UI, temporarily disable “Self‑protection/Active Protection” there first, then sc stop will work without Safe Mode.
- Kaspersky’s Self‑Defense can also block service control; if its UI is available, turn off Self‑Defense temporarily while you run the sc commands.
- Once your Adobe work is done, re‑enable the services you actually need (typically the Scheduler and Cyber Protection service) and leave Active Protection off only if it causes conflicts.
If you’d like, paste the output of:
sc query type= service state= all | findstr /i acronis
and I’ll give you the exact service names to disable on your machine.
