can I transfer my bitcoins on a use or something?
Step 1. Make certain you have no virus or malware running on your computer.
Step 2. Choose wallet software for your computer (Such as MultiBit or Electrum). You can see additional options under "Desktop" here:

Step 4. Install the software on your computer.
Step 5. Create an encryption password that you won't forget for your wallet if your chosen software supports that. If you forget this password it will become impossible to ever access your bitcoins again, so choose carefully and perhaps consider storing this password somewhere secure.
Step 6. Create a backup of the wallet data from the chosen software (Each software has a different method of creating a backup. You should learn the method for your software in step 3). Store one or more copies of this backup somewhere secure. If your computer crashes or is destroyed then this backup will allow you to access your bitcoins.
Step 7. Get a receiving address from your wallet software. (Each software has a different method of providing receiving addresses. You should learn the method for your software in step 3).
Step 8. Send a transaction from Xapo to the receiving address that you acquired in step 7.
Step 9. Wait for the transaction to confirm.
