Windows 10: Repair Windows by reinstalling

I upgraded my laptop to Windows 10 when the upgrade was free. Now my laptop is running very slow and I want to start from a fresh install, but I don't have any media to install from, since it was a free upgrade download. My son bought Windows 10 home to reinstall his laptop. Can I use the same usb to reinstall my laptop without loosing the info that it is registered to me already? I don't want to have to buy another copy of Windows if I don't have to.

:)

 

[Solved] Windows 10 keeps reinstalling KB3119142

I noticed quite some time ago that KB3119142 (Update for Microsoft Visual C++ 2012 Update 4 Redistributable Package) kept reinstalling itself for some reason. At least once daily. Sometimes up to several times a day. I just ignored it. It didn't seem to be doing any harm. And I figured they'd eventually fix it. Well...days turned into weeks, weeks into months, with no end to the problem in sight. It dragged on unsolved for at least the last few months. Literally reinstalling itself hundreds of(at least a hundred, felt like more) times in that period of time.

So I finally googled it a couple days ago. And just got around to fixing it today. Which appears to have worked. And it couldn't have been easier to do. I feel so stupid to have let it intimidate me for so long.*Oops!

Below are links to the thread that I got the fix idea from, and the official MS support info page for KB3119142(from which I quoted the above).

Reinstall Windows?

You'll need to reinstall windows. just use repair *Toast :toast:

I'd go with 32 bit, myself, because of compatibility with software, and games..

 

Solution: Repair or reinstall WPT

I had the same problem with WPA disappearing on startup. Tracked it down to a conflict between my installation of the ADK and SDKs. Specifically, Microsoft.Performance.Core4.Data.dll could not be loaded which I could see using fuslogvw.

The solution was to reinstall the Windows Performance Toolkit using the MSI in the ISO.

1. Download the ISO from here: http://go.microsoft.com/fwlink/p/?LinkID=2033686
2. Try repairing WPT by going to "[ISO Drive Mount]:\Installers\WPTx64-x86_en-us.msi", right clicking, and selecting Repair. This didn't work for me because I didn't have WTP installed, but it might for you so it's worth a try. If it doesn't work continue to the next step.
3. Run the MSI mentioned above. This installed WPT for me and WPA was able to run again.
4. If that doesn't work then try installing WPA from the Windows Store.

I had also tried uninstalling/reinstalling the SDK and repairing Visual Studio, but neither of those things worked.

My sources tell me that the conflict between various installers is being ironed out so this shouldn't be such a pain in the future.
