With how fast SSDs have become, storage has been nearly eliminated as a factor in slow Windows boots, and now other factors like BIOS checks and hibernation affect boot times more. I’ve tried several and ranked them by usefulness and how much time they saved.
Beyond boot times, getting into the OS also takes a moment, and that hesitation comes from how Windows controls launching services and startup apps. Personally, I want startup apps ready as soon as I log in, but Windows deliberately delays them and waits until it hits the idle state before launching them. That delay can be annoying when you expect everything to load superfast on a high-end system.
Why Windows makes you wait before your apps even load
Blame it on the hardware from a decade ago
Windows tries to decide what’s best for your PC; even though that same behavior may not suit every system, it applies universally. One example is the startup delay for apps, which is meant to protect older hardware but can hurt productivity on higher-end setups. Two registry settings control this behavior.
In the first setting, Windows waits a few seconds to after it finishes loading services and the OS itself. Second, Windows waits to reach an idle state after finishing services/drivers and background work, and waits for the system to report idle before starting apps; this can take 10 seconds and may take longer than you need for your PC to load apps after logging in.
This approach spreads out Windows’ startup workload and prevents resource overload.
How to kill the startup delay for good
Different values, different reasons
To remove the time delay on Windows when starting apps, change the StartupDelayInMSec value; to change how long Windows waits to reach idle before launching startup apps, change the WaitForIdleState value, and update both values in the Registry Editor. To do that, follow these steps:
- Open Registry Editor.
-
Enter this address:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerSerialize. - If Serialize doesn’t exist, create a new key with that name.
- Under Serialize, create these two DWORD 32-bit values if they don’t already exist: StartupDelayInMSec and WaitForIdleState, and set their value to 0.
The startup delay is usually 10 seconds and is a Windows 10 behavior carried over to Windows 11. Similarly, the waiting-for-idle mechanism can also stretch past 10 seconds, and combined, they can take 20 seconds after Windows loads for startup apps to start, and that’s a lot of time before you can actually start using your PC.
Another delay hiding in your services list
Same idea, different registry key
Aside from startup apps, Windows also marks several other features as secondary and loads them after the OS properly boots; like startup apps, this adds delay and is intended for slower hardware.
Functions or services like Xbox services, Bluetooth, Windows Update, and similar items that might be integral to one’s workflow may load slowly because Windows doesn’t want them competing for resources while the kernel and drivers load at startup.
Usually, the delay is around 120 seconds before Windows loads these non-essential services, and this behavior is legacy and unnecessary on newer systems.
You can either reduce the delay from 120 seconds to somewhere like 30 seconds or zero.
To do so, follow these steps:
- Open Registry Editor.
-
Enter this address:
HKLMSYSTEMCurrentControlSetControl. - Find AutoStartDelay or create this DWORD 32-bit value if it isn’t there, and change its value from the default to 30 seconds (30000, since the value is written in milliseconds), or change it to 0.
Most modern systems can load the kernel, drivers, startup apps, and these non-essential services all at once, so once Windows boots, you won’t really have to wait to do anything, and changing it to 0 is fine.
What my desktop feels like now
Not faster to boot but faster to use
After applying these registry tweaks, Windows doesn’t wait a set period to launch my startup apps and services; it initializes them alongside the services and OS load. These tweaks aren’t meant to make Windows boot faster, but they do make the OS usable sooner, since you won’t have to wait for Windows to initialize these apps.
I no longer have to sit and stare at the screen while my PC loads startup apps like Claude, WhatsApp, Slack, or Windows services like Xbox, knowing it can handle everything at once.
Don’t forget to back up your registry before making any changes
Changing registry values is delicate, and a single mistake can break your OS, so I recommend backing it up before making any changes. However, these registry tweaks make Windows more tolerable and can also make your PC usable faster by reducing the wait time after you log in, so it’s workable from the moment you boot.
