Avast blocks install of Hyper-V manager on Windows 10 (Error code: 0x80071A90)

[REDACTED]

I recently upgraded my Windows 7 machine to Windows 10.

I found that Avast (Avast Pro v11.1.2245) blocked my attempts to install the Windows 10 feature for Hyper-V management.

Trying the following steps:
Control Panel-->Programs and Features-->Turn Windows features on or off
Hyper-V-->Hyper-V Management Tools

Resulted in the following error:
Windows couldn't complete the request changes.
The function attempted to use a name that is reserved for use by another transaction.
Error code: 0x80071A90

Temporarily disabling the Avast shields allowed the install to complete without error.

Is your system 32 or 64 bit ?

+1 here, same issue. Disabling Avast shields also helped. Os is 64bit.
(Hyper-V requires 64 bit:
It requires a 64-bit system that has Second Level Address Translation (SLAT). SLAT is a feature present in the current generation of 64-bit processors by Intel and AMD. You’ll also need a 64-bit version of Windows. (from Hyper-V docs))
