Windows Installation Issues
Since you've tried multiple SSDs and installation methods, it's possible that the installation media itself is corrupted. Try creating a fresh installation USB using the Media Creation Tool and ensure it's properly formatted. Wiped and created installation USB multiple times. This is using 2 different USB thumbsticks - have also tried Windows built in reset
Some users have reported that Windows 11 installation can restart in a loop due to incorrect boot order settings. Double-check your BIOS boot priority to ensure it's set to the correct SSD. Boot order is definitely correct and set to correct SSD. After first 2 failures, I started doing all the re-installations with only the boot SSD connected to board.
Microsoft Store Slow Loading
A default Windows 11 feature (BitLocker software encryption) can slow down SSD performance by up to 45%. You can check if BitLocker is enabled using:
manage-bde -status BitLocker disabled, was never enabled.
If it's enabled, consider disabling it temporarily to see if performance improves.
Reset the Microsoft Store cache by running:
wsreset.exe Tried, same issue.
Some users have also found success by reinstalling the Microsoft Store app. Tried, same issue.
Outlook Freezing
Outlook freezing on Windows 11 has been linked to large mailbox sizes, add-ins, or corrupted profiles. Try:
Running Outlook in Safe Mode (Outlook.exe /safe)
Disabling unnecessary add-ins (File > Options > Add-ins)
Creating a new Outlook profile (Control Panel > Mail > Show Profiles)
Mailbox is small, definitely not corrupted, no add-ins enabled.
Notepad Sign-In Delay
Some users mistakenly believe Notepad requires a Microsoft account to function, but it only does for AI-powered features. If sign-in is slow, try:
Running Notepad as an administrator Tried, same issue.
Checking for Windows updates (Settings > Windows Update) All of them have already been done.
Installation Failures (Firefox, NVIDIA, PowerToys)
Firefox installation failures can be caused by corrupted installation files or Windows Defender blocking the process. Try:
Running the installer as Administrator Tried, no success.
Downloading a fresh setup file from Mozilla Tried, no success.
Disabling Windows Defender temporarily during installation Tried, no success.
Found that issue is with online installers, my further findings after quotes.
Winget Slow Scanning
Winget scanning delays have been reported by multiple users. Try:
Running winget upgrade in PowerShell (Admin) Tried, same issue
Checking if Winget servers are down Not down as installations work, just have a huge delay
Reinstalling Winget (Get-AppxPackage Microsoft.DesktopAppInstaller | Remove-AppxPackage then reinstall via Microsoft Store) Would try this but as PowerToys had issues in MS store, was not going to risk losing winget to attempt this.
UAC Delay
Some users have reported that UAC prompts take longer to appear on Windows 11. Try:
Disabling Fast Startup (Control Panel > Power Options > Choose what the power buttons do) Already attempted this, one of the first things I do after windows install
Running sfc /scannow again to check for corrupted system files
Did some more work on the PC today, managed to narrow down the issues I'm experiencing. I have also found that the issue is replicated on both Pro and Home editions :(
Online installers are failing
Tried to install FireFox using their online installer. Fails. Tried installing using their offline installers, works.
NVIDIA app was installed using an offline installer for game ready drivers, succeeded. NVIDIA app fails to update itself.
PowerToys fails via Microsoft store, works using winget and github download. Unsure how winget actually works but seems to work fine, just takes a while to scan for updates compared to before I started all of this.
All the other programs I've had to download and succeeded with were all offline installers.
No issues downloading installers from browsers, only when running online installers.
I don't know how Steam works but I don't really have issues with installing games on there so I may be wrong on online installers.
Microsoft having issues with my network (possibly??)
During W11 set up without network bypass, I'd get to one section > next > network dropped error > try again > section immediately loads > next > network dropped > repeat
Microsoft store takes a while to load.
I'm going to assume that the Outlook issue I have where it will freeze for 2-5 minutes after opening is the application trying to authenticate/communicate with servers but struggles. Outlook profile is tiny and profile is fine as it works on other devices.
Possibly explains delays in winget
I don't think it's directly an issue with my network/port/cable though as I have absolutely no issues with streaming, browsing, gaming. No major concerns on ping test, down/up speeds are what they should be, drivers up to date.
More
Memtest86 found no issues with memory after 4 hours, all tests passed with no failures.
Was going to contact support but 40 minute wait, I'll leave that for tomorrow. Posting this in case someone else knows whats up.
