Slow performance while launching inDesign 2021 and other Adobe apps on Windows 10

Some considerations here:

(1)  For the first time after updating to a new version of these applications, they create new sets of preferences and configurations, possibly converting them from earlier versions of the same applications.

(2)  Check how many fonts you have installed on your system. Part of Adobe application initialization is spent enumerating all the fonts you have installed on your system. If you make changes (adding, deleting, replacing) to the fonts, these applications do a full font enumeration which could account for an awful lot of disk and CPU activity before the applications are ready to use.

(3)  In conjunction with (2), if your computer is still using a conventional magnetic rotating disk drive, most seriously consider updating it to an SSD (solid state disk). These days, that is probably the most dramatic and cost effective way to boost your computer's performance (including application start-up time and font enumeration). And if you do still have an old, antique spinning disk drive, make sure you defragment early and often. (Note that SSDs don't require any defragmentation since there is no mechanical overhead to access non-adjacent disk sectors!)

Hi there,

Sorry to hear about this trouble. Could you please confirm when did this start happening? Are there any recent changes made to your system? For example, any antivirus, system updates or web extensions installed recently. 

Try booting the system into Safe Mode ( https://support.microsoft.com/en-in/help/12376/windows-10-start-your-pc-in-safe-mode ) and check how it works there. It starts your system so that it performs certain checks and prevents third party software/ services from automatically loading or opening. If it works fine in Safe mode, then there is some third party service or application like antivirus, plugins or web extensions which are conflicting with the InDesign.
