Try playing a game that uses VAC. I can only play Team Fortress 2 for 10-15 minutes before it crashes.
Nice good for you. But many people are experiencing this problem and I believe it started since the early builds.
I got from Windows update a new AMD display driver 4/2/2015 15.200.1006.0 but i get 0x800f024b error. I updated it manually BUT: 1. Two applications one the Lumia Recovery Tool and iTunes won't open with this installed. 2. The included Catalyst setup (ccc2_install.exe) won't install also since it gives an NSIS error (Installer Integrity Check has failed. Incomplete or bad download) and blah blah. Revert the driver back and both apps working fine again!
Chrome "sucks" on Win7-10, it's not exclusive to any build, some updates that are pushed, especially on beta-dev-canary builds can cause issues with usability. The most recent update for the beta channel causes the browser to crash upon exiting. This happens on all versions of Windows, I just changed to the dev channel and all is good again.
For me FRAPS, Alice: Madness Returns, The Longest Journey (CD), dxdiag, Potplayer x64 are crashing at startup. Firefox also crashes sometimes.
I assume you have Homegroup set on all of your computers and it worked fine on 8.1. If so you, and you have not done this, you might try stopping Homegroup on all of them (right click Homegroup, Change Home Group settings, Leave the homegroup). then restart Homegroup on your main computer, then the others. Don't forget to check the 'Allow all devices ....' in Change HomeGroup settings.
