NOTHING Is Working On My PC After Upgrading to Windows 10!

You can try an in-place upgrade repair install- but first check your disk:

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- else do not proceed.
Post back the result, which you can get after a restart as follows:
How do I see the results of a CHKDSK that ran on boot? - Ask Leo!

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, and x64 if you have a 64 bits OS, else x86 (32 bits).

Recommendation:
Before you perform the following major repair procedure, do create a disk image (see below).

Repair Install Windows 10 with an In-place Upgrade - Windows 10 Forums
- this includes a link from which you can obtain Windows 10 iso file (" download a Windows 10 ISO"), or create a bootable medium.
(If you are using a non-UEFI BIOS e.g. your PC came with Win 7, ignore comments about UEFI and secure boot)

I would recommend creating the bootable medium, as this can be used
- for any future in-place upgrade repair install
- to boot from and use its recovery options should Windows become unbootable.
- to clean install Windows

This will refresh Windows, after the manner of a Windows installation.
- all/most associations will be unchanged
- all your programs will be left installed
- no personal data should be affected
- 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.


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.

I have an issue though. I believe my keyboard is USB 1.0. My mobo doesnt recognize it while booting. I dont have any other keyboards. Do I need to boot into my USB Flash drive with the Windows 10 ISO, or can I simply run it from Windows 10? Also, the ISO download from Microsoft's website is sooo slow.

Hello, how does your keyboard limitation affect this as you see it?

I use ADSL (telephone line) for my internet, and haven't experienced download speed issues for iso's from MS.
But of course that could depend on your ISP, your local area, congestion, sthg on your PC..... guess you'll just have to be patient.

Do I need to boot into my USB Flash drive with the Windows 10 ISO, or can I simply run it from Windows 10?

I can't understand that, sorry.
I would strongly advise that you do the in-place upgrade without downloading updates.
Why? you have slow internet it seems- and it introduces unnecessary complications. You can do the updates later.

An in-place upgrade is started once you have logged in in normal mode. See the guide (URL).
A clean install would be started by booting from Win 10 installation media. You don't want to do that, I think.

Use step 4 or step 5
You can do the same if you burn the iso to a DVD

It's better to have a bootable medium for Win10 to hand 'cos it has recovery features ready for you to use.

'run an iso' doesn't really mean anything.

An iso is a compressed set of files. Effectively with any of the above you expand the iso and then run setup.exe from amongst the files you have extracted from the iso.
