Windows 10: Win 10 repair install

Since upgrading from Win 7/64 to win 10/64 am getting startup issues such as "page faults". Device manager is fine, hdd is fine, ram is fine, however sfc shows rasman.dll errors. Have tried re-registering the file without success.

So I was wondering how does one do a repair install if (as most of us) have installed win 10 from the free Win 10 download - ie one has no media from which to run the repair install?

Is there a download site for win 10?

Note in our case we have the original Win 7/64 disk and coa - we don;t have uefi bios.

How to roll back from automatic repair?

Thanks!

If I repair install win 10, all my old files are intact? I donot want my files are gone after the installation...

And can I still move back to win 8.1 after this repair installation?

 

I do it via the Media Creation Tool, just choose 'upgrade this PC'.

My notes and observations on in-place upgrade repair installs:
Precede it with this in case sthg has happened to your file system:

From an admin command prompt
[Windows key + X, click command prompt (admin)]
chkdsk C: /F
Your PC will need to restart.
Make sure the result is clear or fixed.
Post back the result, which you can get after a restart as follows:

An In-place upgrade repair install will fix many things, but not those where the settings are not changed by the procedure.

For this you need an installation medium with the same base build as you have installed.

This will refresh Windows, after the manner of a Windows installation.
- all/most associations will be unchanged
- all your programs will be left installed
- you will lose any custom fonts
- you will lose any customised system icons
- you may need to re-establish your Wi-Fi connection
- you will need to redo Windows updates subsequent to the build you have used for the repair install
- Windows.old will be created
- system restore will be turned off- you should turn it on again and I recommend you manually schedule a daily restore point.
- you will need to redo any language downloads including the display language if you changed that)
- inactive title bar colouring (if used) will be reset to default
- if Qttabbar is installed, you need to re-enable it in explorer (Options, check Qttabbar)
This is one of the better features of Win10: as each major build comes out, that's your updated reference build, and as updates are mostly cumulative, there will be few to do.

Recommendation:
Before you perform this major repair procedure, do create a disk image.

Please consider using disk imaging regularly. It's a brilliant way to
- preserve your system (and your sanity)
- back up your data
- restore your system to a previously working state in a relatively short time

Recommended: Macrium Reflect (free/commercial) + boot disk/device + large enough external storage medium.
