KB4023057 promises to provide the Local Group Policy Editor with control, not only over the target version 21H1, but also over the target platform Windows 10 — I do not want Windows 11 getting installed while it is the mess that it is reported to be.
Yesterday, on my 64-bit Pro desktop with the most recent 21H1, I installed KB4023057 — no problems — and I quickly found the new LGPE field where I could insert ‘Windows 10’.
Then I installed it on my wife’s 64-bit Dynabook Satellite Pro C10-H, also running the most recent 21H1 Pro (and deemed suitable for Windows 11, which my desktop is not), It was offered by Windows Update, and it seemed to install OK, but unfortunately things are now crook in Tallarook:
1. There is no new field to insert ‘Windows 10’ in the LGPE, contrary to the promise.
2. The update KB4023057 is listed on Windows Update –> View Update History as ‘Successfully installed’, but it is NOT listed in Control Panel –> Uninstall a Program –> View installed updates. This means that I cannot uninstall it and try again.
3. Windows Update informs me that everything is up to date.
So I now have no defence against Windows 11, and I have an update that seems to be partially installed. What does a non-techie do now?
