Q: How can I disable SPTD on my computer to check if it causes problems?
A: If your system has some problems with SPTD installation you can do as follows:
If your system is already running then go to step 2 directly. Otherwise start from step 1.
Step 1. Boot in safe mode and press ESC key when you see on bottom line of display: "Press ESC to cancel loading SPTD.sys". This will abort loading of SPTD layer.
Step 2. Find "HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Services\sptd" registry key in REGEDIT and set DWORD Start value to 4 (i.e. disabled).
Step 3. Reboot again in normal mode and check if your issue is solved.
To reenable SPTD restore the DWORD Start value back to '0' and reboot your computer.
