Context menu appears slow with right mouse click on desktop on Windows 8.1

When I right clicked on my desktop it took about 30 second until the context menu appeared. I tried to solve it with updating the graphic card drivers but it still didn’t help. Finally I found the solution.

Delete all Graphiccard related entries in the registry:
HKEY_CLASSES_ROOT\Directory\Background\shellex\ContextMenuHandlers

How to make a member Domain Controller to the primary Domain Controller in an emergency

So if you can’t recover the Primary Domain Controller then you have no other choice than making a member DC to a PDC. You can seize the roles with ntdsutil.

Run command prompt with domain admin rights:
1. ntdsutil
2. roles
3. connections
4. connect to server MyMemberDC
5. q
6. Seize domain naming master
7. Seize PDC
8. Seize RID master
9. Seize schema master
10. q q
11. dsa.msc

* We don’t seize Infrastructure Master because it should be on another DC where the Global Catalog isn’t installed.
* You can get help in ntdsutil anytime if you just write help and press enter

Google Cardboard – virtual reality cheap for your smartphone

I have always been a big fan of virtual reality but haven’t been following it for a long time. Somewhere on the net I heard about Google Cardboard and I thought i give it a shot. I didn’t have very high expectations because it is made just of carton, lenses and magnets. To my suprise the experience was awesome.

Run Android Apps on Windows or Mac

There are several software (emulator) to run android apps on your windows or mac computer. I tried so far BlueStacks and Genymotion. BlueStacks made a cluttered and slow impression and Genymotion worked smoothely and fast.

Here you can download Genymotion:
Genymotion

If you want to install Android apps on Genymotion you need to install Google Play Store first. Follow this step by step:
1. Create a virtual device
2. Download the right Google Play Store version
3. Drag&Drop the zip file in the running virtual device
4. Let it install and restart the device
5. Run Google Play Store and run all updates
