I was wondering if anyone has had an issue with their computer running slower after upgrading to Windows 10?

That really is an open ended question. Millions of people could say yes and millions of people could say no. It all depends on how the update was performed. If one does a clean install of Windows 10, then you will be dealing with an essentially brand new computer, and it will be as fast as the day it was made. If one just does an upgrade by piling a new OS on top of an old OS, then the computer will run sluggishly and slow. Do a reset and it will pep up your computer.

I did not do a clean install. I did the upgrade so that I could keep my files and programs that I already had installed.

For many years technicians have discouraged doing upgrades and have advised that clean installs were easier to do and more reliable.

This has not changed with W10.

 

I have done many upgrades to W10 at work and have seen many more on the forums here.

It's pretty obvious that a well-used system will have more issues than a new system when doing the upgrade.

We caution customers about this - and advise them of the steps that we'll need to take if the upgrade fails (or if they're unhappy with W10 and the revert to the previous OS fails).

 

And, as this is a fairly common scenario with W10, here's my canned speech about it:

 

Otherwise this tends to look similar to many other problems that we've seen with W10 being installed on well-used systems.

There's a couple of things to try:
1)  Run the following command in a Powershell window that's run as an Administrator in order to re-register the Windows Store apps:

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
From this article:  http://www.thewindowsclub.com/re-register-windows-store-apps
Be sure that Edge is closed (in Task Manager).  Cortana will spit an error as it's still running - don't worry about that for now.

2)  Uninstall your antivirus, then use the removal tool for it (there's a list of most of them here:  http://www.carrona.org/avuninst.html ), then install a freshly downloaded, W10 compatible version.  Some A/V have difficulties with the upgrade, so removing them and then reinstalling them will help how they run.

3)  Download fresh copies of the latest, W10 compatible audio and video drivers for your system.  Then uninstall the current versions from your system.  Then install the freshly downloaded versions.

4)  Get ALL available Windows Updates

5)  Get ALL available, W10 compatible drivers/programs from the manufacturer's website.  If some aren't compatible w/W10, check here about uninstalling them.

6)  Get ALL available, W10 compatible drivers/programs for any add-on hardware and any software that you installed previously.  If they aren't compatible, please uninstall them.

If this doesn't fix things, then post back so we can discuss the following options:
- continuing to attempt to fix this copy of the OS
- Reset of the OS (considering both the "Keep My Files" and the "Remove Everything" options)
- revert to the previous OS (both at less than 30 days, and at more than 30 days since initial update)
- revert to the previous OS with another attempt at installing W10 (I don't recommend this)
- clean install of the previous OS
- clean install of the previous OS, then update to W10 (only needed if a clean install of W10 fails)
- W10 clean install

My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

 In addition to the upgrade considerations, I'd like to know how much RAM you have, since you didn't say.  When I started running Windows 10, I discovered that I needed more RAM to get decent performance.  So I upgraded from 3 GB to 6 GB with my 64 bit system, and now it's as fast as or faster than the earlier versions of Windows.  If you REALLY want to speed it up, put Windows on an SSD.  You can get 240 GB ones these days for as little as $65.

 

 Good luck.


Make regular full system backups or you'll be sorry sooner or later.
