We recently experienced an installation of Windows ten with system files that were corrupt to the betoken that certain sections of the Settings app would automatically close when being opened, amid other bugs around the platform.

Later on attempting typical repair options, we used a Windows 10 ISO to perform an in-place upgrade, reinstalling Windows x while keeping our applications and all.

If this sounds familiar, nosotros have covered a similar process using Windows x's built-in "Reset this PC" selection, but that removes your programs and only retains your files and settings on the newly installed operating system, whereas once more, the in-place upgrade even preserves the software you accept installed.

Running an in-place upgrade worked to fix our instance of Windows 10 that couldn't otherwise exist repaired with Command Prompt commands such as SFC /scannow and DISM /Online /Cleanup-Epitome /RestoreHealth – neither of which would terminate their operation on our installation.

The reinstallation can be initiated from within Windows using the setup.exe file on a Windows x ISO/USB drive or from the Media Creation tool, and the process took around one-half an 60 minutes to finish on our desktop PC.

Since fifty-fifty your applications are retained on the resulting installation, if all goes as planned you won't accept to practise much later and it's certainly a path of less resistance compared to fully reinstalling Windows.

Getting started with an in-place upgrade

For starters, the in-place upgrade isn't an selection if you tin't boot into your installation. You must be logged in to a Windows account and that account must accept administrator access. If you're non an admin, you lot will be prompted for credentials when launching the installer.

To check if you have an admin business relationship, search First for "modify business relationship blazon" or go to Control Panel\User Accounts\User Accounts\Manage Accounts\Change an Account\Modify Business relationship Type where all of the accounts on your Windows installation should be listed and those with admin-level admission volition say "Ambassador."

Double-click your business relationship and and so click "Change the account type" for the pick to become from a Standard user to an Administrator.

You can also detect this information past searching Start for Netplwiz.exe. With that application open, select your account and get to Properties then the Group Membership tab for the Standard user/Administrator toggle.

If you lot're unable to make your business relationship an administrator, annotation that the Windows ambassador account is disabled by default and can be enabled from an elevated Command Prompt:

net user administrator /agile:yes | enables ambassador account (relog)

cyberspace user | lists all Windows accounts including the ambassador account

Every bit some other requirement for the in-identify upgrade, your Windows ISO/USB drive/Cosmos Tool must contain the aforementioned edition of your operating organisation (or newer), as well as the same language and compages (32/64-fleck).

You lot'll also need some spare storage on the Windows drive -- around 8GB when nosotros tested.

Conveniently, this step in the installation will help you with storage information, displaying capacity usage for different areas of your operating arrangement, and you can also choose a secondary/external storage device from a drop-down menu of every bulldoze fastened to your PC.

Although you'll proceed all of your files and software, the reinstallation will delete certain items such as custom fonts, system icons and Wi-Fi credentials. Nonetheless, as function of the process, the setup volition also create a Windows.erstwhile folder which should have everything from your previous installation.

If you have a UEFI system with Secure Kicking enabled, it'southward suggested that y'all disable Secure Kicking earlier starting the in-identify upgrade and then re-enable the feature afterward.

Actually starting the in-place upgrade

Commencement the Windows setup (setup.exe) past mounting the ISO or opening the Windows USB installation drive from the File Explorer.

Windows 10 has native support for mounting ISOs by right-clicking and choosing Mountain or by using the following PowerShell command (our installation was so broken that the right-click option wasn't available to u.s.):

Mountain-DiskImage -ImagePath "C:\FileName.ISO"

Subsequently launching setup.exe or the Media Creation tool, you'll have the choice to upgrade now or to create an installation ISO/USB drive -- y'all want to Upgrade this PC now. You lot might be prompted to download updates prior to this option being bachelor.

The installer will perform some initial setup/scans and eventually enquire what you want to keep on the new re-create of Windows.

If you intend to keep your currently installed software on the repaired operating system, make sure that "apps" are listed and not only "files" (Keep personal files and apps).

The rest of the in-identify upgrade amounts to waiting nearly a half an hour for Windows to reinstall, which rebooted our system several times and didn't require whatever further intervention from u.s.a..

When completed, you'll load back into the same Windows environment where you originally started the "upgrade," except with newly installed operating arrangement files which should be bug-free.

After completing the in-place upgrade

As mentioned before, although this reinstallation retains your software and settings, the process creates a Windows.erstwhile folder with data from your previous copy of Windows. This folder occupies a large amount of storage and isn't easily deleted directly from File Explorer, though you tin can browse the contents at C:\Windows.erstwhile.

Disk Cleanup can delete the Windows.old folder as well as other temporary installation files used in the setup: Search the First carte du jour for Disk Cleanup and and so click "Clean upward organisation files" to run a secondary scan that will locate Windows junk files.

When we scanned later the in-place upgrade, Deejay Cleanup found 3.61GB of "Previous Windows installation(due south)" and 225MB of "Windows upgrade log files."

If you're really low on storage space, we've found that tertiary-party software such as Wise Deejay Cleaner volition remove more data than Deejay Cleanup, and that particular tool even removed more than than CCleaner.

Other than deleting backlog Windows data, you'll probably have to relog into your Wi-Fi network and you may have to install some Windows updates if you didn't use the nearly recent Windows ISO. Withal, that ought to be most the extent of your chores after the in-identify upgrade/repair installation.
