1) I upgraded my desktop PC from windows 8.1 to windows 10 on the last day the free upgrade was available in July 2016. That currently feels like the worst decision I have ever made involving a computer 2) Immediately the PC developed instability issues and would repeatedly freeze meaning I had to reboot the PC numerous times a day. After battling this for a couple of weeks or so things seemed to stabilise somewhat 3) The instability issues returned again a few days ago and were becoming progressively worse. On Sunday Nov 20th and Monday 21st the frequency of the freezing meant the PC was unusable 4) Yesterday evening (Nov 21st) and this morning I have tried to fight the instability issues. I can't see anything of use in the event viewer giving me what appears relevant clues. I next uninstalled some programs I don't use. Then from searching online I tried installing a free tool named Ccleaner. I have tried to do some stuff with that to try to tackle this win 10 instability 5) This is where Viivo comes in. A week ago (Nov 14th) I installed the free version of Viivo to give it a try to see what it's like. After the actions mentioned in step 4) Viivo no longer works today. Specifically:- a) when I add the password at the Viivo password prompt, the [next] button remains greyed out when I click the [forgot password?] button, I get this message:- "You have not previously logged in on this device. To keep Viivo secure, passwords are not recoverable from unknown devices. Please recover your password from a device from which you have previously logged in." This message is ironic since I have only ever used Viivo with one device (the device on which that message appears). From what I have read on viivo.com/support there is some kind of a key that should be on the PC that holds the password. Thus the conclusion to draw seems to be I have done something to that password key (moved or deleted it in error).
* The folders of which I encrypted the contents with Viivo are all on Microsoft One Drive. When I look in One Drive it says there are no previous versions of the files that are now encrypted. I'm not aware of the files that are now unencrypted version being available anywhere else. * I took a back up of the registry with Ccleaner before I did the registry clean with that tool. I have the registry backup file and I have tried to run 'merge' to restore this. I get this message:- "Cannot import registry backup.ref: Not all data was successfully written to the registry. Some keys are open by the system or other processes, or you have insufficient privileges to perform this action." Unsure how to action successfully the registry restore I've used Recovery within Windows 10 to go back two restore points (1st to Sun 20th, 2nd to Fri 18th). This has made no difference to issue.
Can anyone please direct me on how I can progress this please so I can regain access to the encrypted files? Any help is hugely appreciated.
