Somehow, I have managed to get rid of it. I started to download Zero Install, but it seemed to be downloading something called Deepl, which I hadn't heard of, so I cancelled the download. Then I...

Unfortunately, I was unable to open WinSpy after I downloaded it as I don't have an app associated with the file, apparently. THanks anyway.

Many thanks for your suggestions, dalchina. I think I'll give the install/uninstall option a try. Looks like the easiest suggestion for a computer-illiterate oldie like me!

Many thanks for your reply. I meant that System Restore didn't help with the problem.

Every time I start my computer (version 21H2 OS Build 19044.2075), a small window appears headed Zero Install with the words "The system cannot find the file specified" (see attached). This...

Oh dear, it's getting a bit too involved for my old brain now, but thanks again for taking the trouble to reply. I'll use web mail.

Thanks for your reply, Bastet. I don't have two-step verification activated on Yahoo or Gmail and have used their normal passwords. I had no trouble setting up email accounts on my Windows 10 laptop

I recently bought a Fusion 5 tablet with Windows 10S operating system. I find I cannot add ymail and gmail email accounts to the native email client: it just hangs saying "Creating account" and...

So it won't work. Thanks for the info, syntoh.

Well, I've connected it back up to my computer and the light has reappeared.

Thanks for your reply, Berton. I see what you mean about the light but I have the drive plugged into the mains electricity supply as well.

I have a Western Digital My Book Essential external hard drive connected to my desktop computer by USB. I wanted to connect it instead to my Sky modem-router. Because the router does not have a USB...

Both my wife and I have administrator accounts on our PC. If my wife scans a document and saves the file in the Public Documents folder, both she and I can read it. If I scan a document and save the...

No, it didn't self-correct but I understand it will after the October update.

There has been a development on my problem with Mail app.

To recap, I have five accounts on my Mail app: outlook.com, gmail.com, ymail.com and two mail.com accounts. A little while ago I found...

Thanks, guys, I'll have a think about it. In the meantime I have Thunderbird and a fully functioning Mail app on my other computer.

Maybe not difficult for you, Ken, you're a guru! "Adjust BIOS", "disable Secure Boot" - too much for this senior citizen, I'm afraid. But thanks very much for your interest.

Thanks, Ken, but I'm afraid that is a bit beyond my limited computer skills! I did try the registry option but the keys for the problem accounts are not present in the registry of the problem...

Thanks for these, Ken. Can you go into a bit more detail, please, about what you mean by uninstall again and run an inplace repair? And no, none of these accounts has the same address as my MS...

Yes, Ken, it's rather ironic that the only account that gets deleted when I do a Powershell uninstall is the outlook.com one. I wonder what that's got that the other four don't have.
Could there be...

Yes, Ken, you're right, I had to add back the outlook.com account, and I got the two gmail accounts.
I have already tried the Reset option without success.
And I can confirm that all four accounts...

I ran the sfc /scannow and got "Windows resource protection did not find any integrity violations". I was referring to the account settings in the Mail app itself. Funnily enough, in Email and App...

Thanks for your replies, Ken and Helmut. Both of you make reference to removing the accounts from the email app. Unfortunately, that's just what I can't do. Account settings doesn't respond any more...

Thanks Ken. No, there are no problems accessing the accounts through a Web browser and indeed on my other computer there is nothing wrong with these accounts on the Mail app. I believe the problem...

I have one outlook.com account on my Windows 10 Mail app and four other email accounts. Today the four other accounts stopped working. Clicking on them, left or right, makes no difference, they are...
