Windows 10: Lenovo Thinkpad T420 clean install after upgrade.

Just purchased a refurbished T420 with win 10 pro updated from win 7 pro, am wanting to do a clean install.
Anyone running a T420 on win 10 would appreciate any advice.
my only concern is obtaining correct drivers or will windows install them.

Windows 10 alerts on Lenovo ThinkPad T420 Error The external tool "DiskDefragmentationGUI" could not be found for os "Windows Unknown Major Release Service Pack 0 Professional x86 64-bit" .

Original title: Windows 10 alerts on Lenovo ThinkPad T420

Ever since installing Windows 10 on my Lenovo Thinkpad T420, Lenovo Thinkvantage Toolbox generates the following message: The external tool "DiskDefragmentationGUI" could not be found for os "Windows Unknown Major Release Service Pack 0 Professional x86
64-bit" . I see on line that others have the same issue, but neither Lenovo nor Microsoft seem to have offered any solutions yet. I also get at the same time two quite similar messages with the following differences: "PrintersAndFaxes Folder" and ""NetworkSharingCenter"
instead of "DiskDefragmentationGUI". Can anyone help? Rick.

 

In general Windows looks up drivers from an evolving database and provides them.

Occasionally the driver version is inappropriate; much less frequently a driver might not be found.

If all drivers are found without problems, do nothing more about driver maintenance.
We (almost never) recommend the use of driver scanner tools.

Note the Win 10 version on your PC may not be the newest major build; if so the iso you download may be newer, and might give rise to new issues.

(Check your version number with
Windows key + X, winver)

 

Export the existing drivers before you do the clean install. On a USB flash drive with at least 8 GB free space, create a folder called Drivers - or whatever you want. Let's say the USB flash drive has drive letter F:

In a Command Prompt (Admin) or Powershell (Admin) run:
dism /online /export-driver /destination:F:\Drivers

The path in red will be to the external storage folder you create to hold the exported drivers. It can be on a NAS, second hard drive, or USB flash drive. You can even create this folder on the same USB flash drive you are using to install Windows with - if it has enough free space.

After the clean install, if you do need to re-install any drivers that Windows does not do automatically, then just manually install them from the Drivers folder you exported to.

 

Thanks for the advice no problems all drivers found.
apart from the lenovo function keys not working no win 10 drivers.

 

One more thing to consider: Lenovo does a good job of supporting its PCs through its support pages. They have a utility called System Update 5 that you can grab from the support pages for your T420 model. Once installed, it will tell you if Lenovo thinks you need any drivers. They don't always move as quickly to recognize updates as they could, but they do a pretty good job of lagging somewhat behind the leading edge...

PS: here's what the utility looks like (I have a T520 and an X220 Tablet, both Lenovo laptops):

 

Thanks for the info will check out system update 5.
This my first Thinkpad and it's far better than most entry level laptops am enjoying the experience.
Have managed to get all the correct drivers and camera and function keys working.
