The 1607 update to Windows 10 I think has caused this I believe. Going to try this tomorrow as a final attempt on my laptop at work. Contacted Comodo help and they said they could fix it but I would have to pay for the GeekBuddy licence. Googled it and tried a few things including disabling the Program Compatability Assistant service and turning off the digital driver checking in troubleshooter at bootup. I tried to install Comodo firewall after the Reset again, but Program Compatability Assistant said its drivers aren’t digitally signed, hence blocking them and not allowing internet traffic through the Comodo Firewall even though the installation goes ahead.

I reset my laptop after the 1607 update as I was having some weird problems occurring. The company states however that Windows will eventually block boot drivers. While the company states that certain setups won't be affected by the change, it appears that at least some of these exceptions will only be temporary.Īs mentioned previously, boot drivers won't be blocked outright according to Microsoft. These changes limit the risk of an end-user system being compromised by malicious driver software. Weâ€™re making these changes to help make Windows more secure. Microsoft notes that the change is done to make Windows more secure for end-users. All previous versions of Windows are not affected. The change affects only Windows 10 Version 1607.They will be removed by the Program Compatibility Assistant however. I am using version 0 as the 1511 not available now through the update. Microsoft took it off I had friends here locally had the same issue also. It wont install I checked the update in windows 10 today & nothing there now just the windows defender updates. Boot drivers won't be blocked to prevent systems from failing to boot. October 6th version didn't make it too, despite I'm with Win 10 Entreprise 1511. It seems this is the next version of windows 10.All drivers signed with cross-signing certificates that were issued prior to Jwill continue to work.PCs without Secure Boot functionality, or Secure Boot off, are not affected either.PCs upgraded to Windows 10 Build 1607 from a previous version of Windows (for instance Windows 10 version 1511) are not affected by the change.

Win 10 pro version 1511 won't install
