On 17th April I upgraded my 2 year old Thinkpad T440s to Windows 10. On windows 7 I could boot in about 45 seconds.
After fixing all the issues, upgrading software etc, all was running well, and Windows 10 was booting in about 45 seconds.
Suddenly, in early May, boot times slowed right down to around 3 to 3.5 minutes. I don't recall changing anything at the time. This has also happened on my desktop machine, also running windows 10. Both are upgrades rather than clean installs.
I've have been searching all over for the solution. I've stopped all sorts of things starting, and gone through all the usual check lists on this forum and elsewhere.
I've created a new user, and can logon to this user in less than a minute, so there is probably something wrong with my main user profile, if I could just find it!
In the application event log every time I boot, I see Event ID 6006: "The winlogon notification subscriber <Profiles> took 158 second(s) to handle the notification event (Logon)." (The time varies but are very close to the extra time the boot is taking). So this is my prime suspect. However, I am in a workgroup, not a domain, and most posts that reference how to stop the logon delay refer to domains, and are also pre-windows 10. I've tried the recommendations that seemed applicable without success.
If I log in from the alternative user, Event ID 6006 does not feature in the logs. I could obviously try to move my applications over to the new user, but I have a lot of heavily configured software and this will take a long while - almost as long as a clean install of windows 10, which is the preferred alternative.
In any case, my concern is that the problem will recur so I really want to find and fix the cause.
I did find the following (abbreviated) post in one forum – food for thought: "Having done many Win10 upgrades, I am of the opinion that UPGRADING to Win10 over an existing user profile IS NOT RELIABLE. It appears to produce a whole range of bizarre operational symptoms. To get your free upgrade, the only way is to upgrade in place. Thus the only reliable way to get an upgrade to Windows 10 is to do the upgrade in place, and then do a clean re-install of Windows 10…. This is the procedure that gets you the most reliable and stable end result."
Other Windows 10 users I know are also complaining that after initially booting very fast, it slows right down and it is back to the bad old days of having to make a cup of coffee while the boot completes!
As I said above, I am hoping the event ID 6006 gives a clue to what might be hanging? Can anyone help?
(I've posted this already on other forums, but no-one has come up with a fix, other than recommendations to do a clean install. I have a sort of workaround - hibernate rather than shutdown!)
Thanks in anticipation! Brendan.
