Microsoft has confirmed what may initially appear to be a mildly, nay, arms-wavingly alarming difficulty with a current Home windows 11 preview construct. Specifically, putting in it “may trigger gadgets to restart repeatedly,” requiring “restoration operations in an effort to restore regular use.”
On deeper inspection, it’s really not fairly so alarming as a result of this difficulty solely appears to have an effect on virtualised Home windows environments that put in the non-obligatory June 26 KB5039302 replace. This replace is a preview construct, which primarily means it’s most of July’s replace packaged for an non-obligatory early obtain.
Fortunately, Microsoft caught the problem earlier than the upcoming July 9 patch. If it had rolled out, some digital Home windows environments—presumably enterprise machines, for essentially the most half—might need failed to start out or repeatedly restarted. However Microsoft says the replace “is now paused just for gadgets affected by the problem” and “may not be supplied to Hyper-V digital machines working on hosts that make the most of sure processor sorts.”
To be clear, evidently it’s solely a problem for virtualized Home windows programs similar to Microsoft Cloud PCs or Azure Digital Desktops, or presumably localised digital machines similar to one you may run on VMWare or VirtualBox. So, don’t fear about your bodily PC which has Hyper-V enabled, as a result of it solely appears to be an issue for any digital machine working on that hypervisor.
Should you do run Home windows on a cloud PC or digital machine and also you’ve put in this replace, you’ll be able to revert and uninstall it from the Home windows Restoration atmosphere as soon as Home windows finally plonks you into it after the numerous reboots. Simply go to Troubleshoot > Superior Choices > Uninstall Updates > Uninstall newest high quality replace, then reboot when it prompts you to.
For the non-virtualised Home windows environments that can obtain it, the KB5039302 replace has a number of good enhancements and fixes. Most likely most related to PC avid gamers is the repair for a problem that prevented some GPUs from coming into idle states when not in use. There’s additionally a repair for points regarding excessive system CPU utilization attributable to the Home windows Filtering Platform (WFP) driver, which is utilized by firewalls and so forth.
So, extra CPU efficiency freed up for pumping out the framez, and a smattering of GPU customers seeing much less energy draw. What’s to not love? Oh, proper, the boot loops. Sorry, digital desktop customers!
