Ha yeah, you're probably right, but I naively thought that the repair install would be quicker, easier and less hassle than a full factory reset or clean install, little did I know
Anyway it's all moot now as I've managed to get the repair install to (finally!) work! I can barely contain myself!!
I've had a busy week but after the last failed attempt, I got a few updates on using various methods but still no joy with the upgrade. I then decided to re-run the MS SURT, followed by the All In One Repair in safe mode, after this the WU were still working and showing 28 + 3 optional but none of them would install (usual story). I also changed the owner of the CBS registry key back to Trustedinstaller (from Admin) after something I read of yours Boggin which prompted me to check it, as I've done that MSI registry key fix myself in the past and it was all there ok apart from the Ownership.
Then having exhausted my ideas of what to change I thought it might be time to try the upgrade install again, firstly with the Home premium, which again got stuck, so I tried one of the first pair of Universal disks again and let it rip and went right through to the end! Holy *&$£ man!!
I'm just in the middle of trying to figure out what I need to do now to get everything working normally again and back to how it was - so far I can see my desktop themes are different, appearance is different (I had aero and other effects off before for better performance), Avast has been turned off for some reason and won't start again, either with the shortcut or with the Action center button - it says the side by side configuration is incorrect! Any idea what I need to do to get it going? The Windows Features box is now visible again after a long time not working, woohoo, and WU appears to be still working, but failed on error 8024001B when I first tried it (update needed to update!), so I've rebooted and tried again, currently "Checking for updates........). Also when my Glasswire connected the first time it came up with a big list of about 10 different items which have all been removed! - do these need replacing or are they all redundant? (I can write the list down if needed, network adapters/drivers by the look of it)
Other than those few niggles all looks to be good, hopefully I can ge the AV back on now and get the WU's all up to date and then the job's a good 'un!!
