Here are a few things that have been a total pain to fix on client computers lately due to windows updates and other crap
1) Outlook 2010 crashes for no reason:
Fix - Uninstall Windows Update KB3097877
2) Stupid Windows 10 upgrade notification.
Fix - Remove by uninstalling Windows Update KB3035583
3) Remove the start button apps/bloatware in Windows 8 and 8.1
a) Open powershell as administrator
b) Enter the following commands in order:
Get-Appxpackage -Allusers | Remove-appxpackage
Get-Appxprovisionedpackage -online | remove-appxpackage -online
You can just copy and paste those lines if you want.
