Hi there,
Upgraded quite a few machines of various specifications to Windows 10 (Home & Pro) over the last few days. The common element was Bullguard.
On some machines BG will load after the update, on others it refuses.
On the ones that refuse, I've unistalled - used the cleaner - used Revo then re-installed and all looks fine until the reboot to bring the Firewall back in.
Right-clicking to run as administrator doesn't help either. When I check the Windows services - all the Bullguard ones are stopped.
If it helps - Windows 7 upgrades seem to do it more than 8.1
Wondered if anyone else had experience this....
