Browser slow to load

“dism.exe /online /cleanup-image /restorehealth” and “Windows Install” has to last option... dism.exe once tool over an hours.

Will trying logging different user.

dism.exe once tool over an hours.  

On a properly working machine, dism will be done in about 15 minutes.

Try another user.

Then, Repair Install is painless and easy and leaves you where you left off. No reason to avoid it so long as you select the Default to keep everything.

Entered with another user and it seems to work fine.  Will continue for while monitor when and if gets slow.

OK, so if it is working well, then back up the data in the user profile, delete it and make a new user profile

also noticed the remote desktop is working fine under another user-name.... strange

It means the existing profile is damaged.

seems that way.  The other user work somewhat ok.  Though there was no halt or prolong loading, it did sometimes show a bit of lag.  

Is there a way to fix this user profile? (deleting this profile is not an option due to that many apps installed under this user an configurations etc.)

Is there a way to fix this user profile?   <--- No. Backup, Delete and Recreate is the only practical way to fix a profile. It is sometimes easier just to back up and reinstall Windows.

Yes as last option... unfortunate all previous  windows restore or any routine to refresh windows has been horrible long and costly due to the users cannot be productlve.

The problem we have is that internet explorer and chrome are slow to load and Remote Desktop and Teamvier also similar behavior sometimes doesn’t connect to another computer in the office.  

That above said, the problem seems to be connections related.

Question,  
What can we look for to try identify the culprit for this connection issue?
(we will go with your recommendation as last resort)

Profile issues cause problems with Office and with Browsers. The issues (long experience on my part) are not technical issues with the products (Office, Browsers) but rather with the profile.

So based on your experience, what can we look for to try identify the culprit for connection issue?

I know that the profile here is the issue

Ok, prior doing you recommendation, we will search possible causes.

If the culprit is inside the Profile, not much you can do.  

If the culprit is outside the Profile, then the new test Profile would not have accomplished anything, but a Windows 10 Repair Install would work.

You can always try a Repair Install

again, those are last resource, but thanx... will continue...

Why would a cable modem (serving many) affect one profile on one computer. That does not make sense at all.

Unless, of course, the defective profile was trying to connect to the cable modem directly in addition to its network connection.

The other profile were a slow also, not as much, but it was.

That is new information about the other user profile and I trust you are now not going to say all the computers are slow as well.

So now on the problem computer, do a Windows 10 Repair Install as suggested earlier. This is not last resort. It is simple, easy and effective.

I said "The other profile were a slow also, not as much, but it was".  It's not new information.  Some days back I said "...The other user work somewhat ok.  Though there was no halt or prolong loading, it did sometimes show a bit of lag." - and of course, I am not going to say now "all the computers are slow as well".

The problem computer is working fine now.  No halts / slow load / RDP / teamviewer problem to-date.  By changing the modem, the problem disappear.  

Nevertheless, I needed to know the "why".  The problem was not defective profile was trying to connect to the cable modem directly in addition to its network connection as you stated.  The problem was the modem.  Unfortunately trying to pry on the "why", no results from the manufacturer.

If you were to brainstorm on possible cause of behavior a modem to act like that, what do you think it might cause this problem?

It was not until the end that you said the other profile was slow. Earlier you said it was fine.

I find the modem solution that is affecting one and not other computers to be strange indeed.

The problem was the modem.  <-- Only, I think because of problems with the one computer OS.
no results from the manufacturer.  <-- No surprise at all.

Nothing more I can do but what I have already done.

It was not towards the end, I gave you the link that places you on the date; and the "lag" was a response on your comment of "It means the existing profile is damaged.", it was not something I just came up with.

Anyways, the purposes of asking for feedback on possible causes is to award the points, have info for other members and close the question.

You can award yourself the answer. That is the best approach here. I would have just fixed the problem computer as that is what we do for clients.

Ok.

Awarded "Assisted Solution" for the time and patience taken to assisted in our questions within the thread and also if the problem would have been the user-profile, the recommendation indicated by the EE would have been possible solution - nevertheless, in our case, the repair and other recommended routines would have not helped.

However, we was informed that the modem was in fact faulty, though no real answers from the provider as to why a specific user-name would have that problem and another within the same computer not.

Last info: after talking to the users one did say that they was testing various way to block by MAC by tweaking the modem software and even try to update the routers firmware but never reported to us.
