I tried updating Windows and the updater fails. Attempts to repair were unsuccessful. I'm now attempting to update to 20H2.
I installed on another PC which has 2004 installed and this works with no problem and OpenCL is enabled with an on board GPU Intel HD Graphics 530.
This apparently is the result of a broken Windows update. The Windows troubleshooter made me think it fixed the update problem when in fact it didn't.
I'll tell you a secret. I'm a Linux user and expert but Windows neophyte. I use Windows only for gaming, photography and, video only because that's where the good tools (like Affinity) are available. I shy away from Windows largely because updates have often broken for me resulting in a huge loss of time -- like now. A Windows PC for me is fine for about a year and then often starts failing updates and gradually loses performance because of cruft. A fresh install of Windows doesn't cut it for me because of the having to re-install all the apps. Any chance at all there will be an Affinity for Linux?
