Just a shot-in-the-dark here, but have you checked the version of the graphics driver on your HP laptop vs what is "current" according to the HP web site?RonH wrote:... Had a bit more of a read and it does seem a bit 'dodgy' to take the 'delete' action.
I would have tried to research the HP site but I do not know what model you have. Be aware that when searching on model numbers use the full model number. For example searching for G40 might not give the desired results because there are many sub models with different specs. There again, perhaps you know that and in which case, apologies.
While using the Windows 10 Pro Insider Preview in my desktop environment I have experienced issues where the Microsoft provided graphic drivers caused many issues. Getting the appropriate driver(s) from the graphic card's manufacturer resolved the issues. However, current MS provided drivers seem to be OK. Sometimes a bit of a gamble.
And as advised by Hans, ensure that whatever action you take, do not forget to create a System Restore Point before starting.
