How can I erase win7 marker in SLIC?

Hi all,

I installed Windows 10 dvd on an old notebook which was running vista(it means I cleaned the hard disk and installed Windows 10 dvd). However win 10 has a minor problems. I'm an insider, so I checked build 10240 and 10547(upgraded last week by windows update). When I checked with showkeyplus, it says "Windows 7 OEM marker present in firmware". I suspect it be embedded in SLIC, but I don't know how to get rid of the "marker".

How can I remove it?

Thanks in advance!

You can't, it's part of the manufacturer programmed bios firmware that doesn't get changed with a standard bios upgrade. Just curious, why do you want to?

To solve the ctrl+alt+del issue:

1. Win+R key to bring up run dialog
2. Type netplwiz and enter
3. Click the advanced tab in the user accounts window that opens.
4. Bottom section, uncheck "require users to press ctrl+alt+del"

My laptop also has the Windows 7 marker and it shouldn't interfere with anything. I think that was just the preparation Microsoft and the computer manufacturers were making to store Windows 8 product keys in bios.

Actually - on another thread someone explained the Windows 7 marker:
How to get the productkey of old OS (Win 7) after upgrading to Win 10? - Page 6 - Windows 10 Forums

Yeah, the OEM-SLP keys are generic keys common to that manufacturer. They are actually blocked from online activation and phone activation. Factory OEM-SLP installs do not activate online, they activate against the SLIC table in the BIOS. That's why the key on the COA sticker is a different key and a unique key. It can activate online, although I've usually had to do a phone activation the first time I used one of those. If you can actually read the sticker that is.

Thank you for ctrl+alt+del problem. But it was unchecked from the beginning. So I cannot fix this. This notebook still requires ctrl+alt+del. Especially when rebooting, the whole screen flicks black and white twice or 3 times, then initial screen appears. Then ctrl+alt+del is required....so I suspect windows 10 is intentionally doing this.

What can I do? I'm at a loss.

Looking at SLIC-toolkit (advanced tab), only "No OEM Certificate found" is red, but this is no longer OEM, so I don't mind.

Now I'm doing "dism /online /cleanup-image /restorehealth /source:wim:f:\sources\install.wim:1 /limitaccess" for sure. Am I off the point?

Windows 10 ( 10240 and above ) has to be installed over a qualifying OS or activated preview edition

It appears you clean installed windows 10 10240 on a blank HDD without a prior windows 10 (Preview) activation or an upgrade from a qualifying OS (Windows 10 upgrade activation)

Really? Actually I clean installed Windows 10 10240. hmmmm....fortunately I have 10162 dvd. If I begin with this, shall I succeed? It will take time and may cost..

EDIT: oops....10162 has expired. It cannot be activated.

Is your current install of Windows 10 activated?
