Dell desktop factory restore

Hello,

I need to factory restore a Dell desktop. Originally it was running win 7 or windows 8. The ckient upgraded to win 10 and it is running so so slow. So I decided to factory restore the desktop. What are the key stroke I need to use to boot up in recovery mode and format this PC ? Ate the key I used for win 7 or for Windows 10? They did the upgrade more than 30 day ago so I don't see the option to undo anymore .

Just in case where should it. E the option to undo the upgrade to win 10 please

Thank you

Have you done a factory restore yet?

Windows 10 is as fast as Windows 8 and faster than Windows 7.  So maybe all you need to do is a Windows 10 Repair Install and Keep Everything.

Go to the Media Creation Link

https://www.microsoft.com/en-us/software-download/windows10

Click on Upgrade to Windows 10 (even if Windows 10 is running), click on the Download button, select Open (Run) but NOT Save. Allow the program to run. Allow drivers to update. Then select Keep Everything.

You need to make sure the computers are Windows 10 compliant.

I5 high end, 8GB of memory, 7200-rpm hard drive or SSD should run Windows 10 speedily. That is what I use and clients use.

i have those specification. they only think I don' t know is about the 7200-rpm hard drive

JohnBusiness Consultant (Owner)Commented:
Unless the computers are cheap (budget models), hard drives today are commonly 7200-rpm.

Try reinstalling one as I mentioned. Also try installing one fresh (nothing kept) and then installing software carefully to see if any legacy software is causing issues.

Let me ask you a question: once the client performed the win 10 upgrade is there a way to go back to the originally factory software won7 or 8 ?

I have a backup, I rather don't keep anything and do it a fresh install

JohnBusiness Consultant (Owner)Commented:
You have to roll back within 30 days (29 days or less) or it is too late.

Roll back from the recovery settings.

Try a fresh install and restore from backup.

ItaliabellaAuthor Commented:
i know the 30 days, so after 30 you will never be able to go back to the original OS Correct ?

ItaliabellaAuthor Commented:
so what happen to the hidden partition that contained the OS for factory restore ?
after the upgrade to Win 10 it get erased ?

JohnBusiness Consultant (Owner)Commented:
Correct. You would need the original install media

JohnBusiness Consultant (Owner)Commented:
It may depend on the computer whether the original other operating system was retained or not. I do not know for Dell.

I am looking at Disk Management on my Lenovo and I think the first recovery partition is still there, but I would not even dream of testing.

So the install was successful and it is just a matter of setting up. Be sure software is new and not old legacy.
