Slow Windows startup with Parallels 14

Since installing version 14, I note the load time for Windows 10 (Home Premium) after rebooting the Mac is about 9 minutes to a log-in screen, another 3 minutes after that before a welcome sound and another 2 minutes before the taskbar has completely settled. I have no anti-virus on the Mac or in Windows. The Mac has 16GB memory (4.096 assigned to Windows), a quad core i5 3.1 GHz processor and fusion drive. CPU stays well within 100% and overall memory pressure is less than half. Hard drive is less than half full. Is there some way to speed up the process?

Like described earlier, the disk usage shows 100%, but no process shows high disk usage. In Mac activity monitor, my windows 10 process shows GB reads. Unable to cleanboot, a forced machine stop is the only option, followed by Disk check in Mac, and delete and reinstall parallels V14. I once again ask if it is possible to downgrade to V13, that is delete V14 and install V13 instead. Please advice.

Hi @BeeMb, we appreciate the time and effort that you have invested in to try fixing the issue. We would request you to create a new User profile to check if that takes a normal disk usage.

Hello PaulChris,
I did the following after your instruction:
1. Take a snapshot (Actions > Take a snapshot)
2. Open Windows menu and search for Command Prompt. Once located, right click it > Run as Administrator.
3. Execute the following commands one by one
chkdsk C: /f /r
sfc /scannow
The first one will require Windows restart, so please restart it, wait for disk check to complete and perform the second command
Please make a screenshot of the output an provide it in answering e-mail
4. After the described actions are performed, please also execute the following commands in Command Prompt (Run as Administrator) one by one
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
5. Please restart afterwards and check if the issue persists.
AND THIS:
1. Take a snapshot in working Windows (Actions > Take a snapshot)
2. Perform a clean boot in Windows as described in Microsoft article https://support.microsoft.com/en-in/help/929135/how-to-perform-a-clean-boot-in-windows
Make sure to keep Parallels services enabled It was performed as one of the first troubleshooting steps when you contacted Parallels Support, but since currently this is a restored VM, we need to perform it once again
3. Take a technical report after Windows starts (immediately after that) or when you are on login screen in Windows (Help > Send technical data) and reply to us with approximate time of start and 9-digit ID of the report
4. Check the following general article from Microsoft on speeding up Windows https://support.microsoft.com/en-us/help/15055/windows-7-optimize-windows-better-performance
5. Clean older updates (and the C: drive itself) as described in https://www.laptopmag.com/articles/clean-winsxs-folder-to-save-space
Once performing all the steps described above please check the startup time of Windows once again and collect a fresh report after Windows starts (or from Windows login screen).
BUT NO ERRORS WERE REPORTED

Once again the note:
I copy the Windows.pvm file from my FusionDrive (start about 7 minutes !!! and all programs start slowly and are slow in the execution) but Windows will start on an external SSD in about 20 seconds.
There seems to be no problem with the Windows installation but a problem with the compatibility with the FusionDrive or the internal hard disk.

My problem started the day I installed V14 on my MacBook Air. After many weeks looking for a solution and a totally unresponsive virtual machine, i bought a new MacBook Pro. Now it runs perfectly. Conclusion : keep away from V14 if you are using older hardware.

I am having the same issue with V14. Windows 10 is taking over 20 minutes to load to login and another 10 before it can be used. Everything on my MacBook Pro is slow to respond when parallels is running. I have deleted it and reinstalled it twice as I have always done with windows. This is ridiculous. Version 13 was fine.

I have generated a problem report number 301471687 this afternoon. I restarted my macbook, started parallels which took 3 or 4 minutes and then started Windows 10 which took 20 minutes from pressing start to the user login screen. Everything on my machine is slower since v14 was installed. What can i do with this? it is causing me great issues trying to work.

Hi....I just want to add my experience here. I have all of the same problems with loading times for Windows, and everything I do within Windows after it is loaded is extremely slow. I have done many of the proposed solutions, and they have not ultimately solved the problems. In short, Windows is simply unusable on my Mac. I will not be renewing my subscription to Parallels if nothing changes.

I rue my decision to upgrade to 14, also! Same slow issues others have mentioned. My times are much longer, though. A good 20 minutes before I can even get a File Explorer window to appear! As with others, I'm hoping for a solution, soon!

I have the same problem, a good average for a startup of Windows 10 is 12-15 minutes since my upgrade to Parallels 14.1.2 I updated Windows 10 with the latest update, 1809. I have tried everything listed on the two pages of this discussion. I sent information on technical report 302508452

Extremely slow start up. for Windows 10 on Paralles 14.1.2. The last one took over 12 minutes.
I'm using Mojave 10.14.3 on a MacBook Pro (13 inch mid 2012) with a 2.5 GHz Intel i5 with 16GB 1067 MHz of DDR3 RAM.
