Generally, the error is because of system corruptions.

Please follow the below steps to resolve it:

1. Run CheckSUR(KB947821).

2. Run sfc/scannow to fix the possible errors.

3. If you find 0x8004a029 in the CBS.log, it is because you have more than 13 filter drivers installed.

Option 1
Windows 7 is hard coded to allow 14 filter drivers, but the following registry sets the limit to 8 by default. You can adjust the amount up to 14 or delete this key and it will be set to max of 14.

Option 2
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\{4d36e974-e325-11ce-bfc1-08002be10318}\

Delete Something that you don't need (Export First) - You can delete for example Virtual WiFi Filter Driver

4. If you encounter this error on a MacBook, probably it is an known issue (

5. The last option is to Perform an inplace upgrade of Windows
