Hi all, I am getting warning messages at boot-up, and after resolving a problem on another thread I was advised to post on this more appropriate forum.
The warnings are > Host Process has stopped working > Internet Control Panel has stopped working > Winpk has failed to load > Windows Shell common DLL has stopped working.
By guidance I have been able to take an Event log and have appended it below,
for your guidance the event id's seem to be 6068/10010/7009/7043 Occasionally and 3688/7000/7026/11 regularly
I will be grateful for any help, regards Robert.
Ps, I had to stop the PC with the power button last night which might show.
