Windows 8 activation fails with Error: 0x8007007B
Windows 8, like previous versions, requires online activation to verify that your key is legitimate. However, some users upgrading from Windows 7 have had problems with the code from the previous version of Windows becoming “stuck” and, since it’s for Windows 7 and not Windows 8, activation fails.

To solve this you need to use the command line. Do a Windows search for “cmd” and make sure you have elevated privileges – you may need to right-click and use “Run as administrator.”
Now type these commands:
slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
In the first command, the “XXXXX” characters should be replaced with your Windows 8 product key. Your activation should now complete successfully.
Blurry or fuzzy text
You may notice that some programs display poorly on your Windows 8 PC. This typically is a problem with older software which was designed for screens that have a lower resolution that those today. Windows will often try to scale the software to a higher resolution, but not everyone likes the blurry appearance that results.
To turn this off, right-click on a program’s executable, go to the Compatibility tab and check the box for “Disable display scaling on high DPI settings.” Then restart the program.
If your problem is with icons and general text, rather than programs themselves, you may simply need to scale the Windows UI. Do a Windows search for Display and, in the menu that opens, change to a larger or smaller UI scale. You can also customize text scaling with the “set custom text size” link on the left.
